Basal Cell Carcinoma of the Nipple-Areola Complex: A Comprehensive Review of the World Literature. - Dermatology and therapy
Basal cell carcinomas (BCCs) usually occur in sun-exposed areas. However, they may also occur-albeit infrequently-in unusual locations, such as the nipple-areola complex.Using the PubMed database, an extensive literature search was performed for the following keywords: areola, basal cell carcinoma, and nipple. Papers and references cited in those papers were reviewed to accumulate reports of patients with BCC of the areola and nipple.BCC of the areola and nipple has been described in 55 individuals: 35 males and 20 females. The onset age ranged from 35 to 86 years. The median onset age in males was 61 years, whereas the median onset age in females was 66 years. BCC of the NAC predominantly occurred in Caucasians (75.7%). BCC of the nipple-areola complex (NAC) was observed on the left (54.9%) more frequently than the right (45.1%). Clinical presentation was variable and commonly included scaly or ulcerated plaques and nodules. This tumor was typically associated with the nodular (42.9%) or superficial (30.9%) subtype of BCC. The most common treatment was excision. There were three reported patients who had metastatic disease to their lymph nodes; one of the patients died from his tumor.The nipple and areola are uncommon sites of BCC. BCC of the nipple-areola complex is less frequently observed in females (36.4%), as this is more commonly a photo-protected site. BCC of the NAC has been considered to behave more aggressively than BCCs at other anatomical sites; however, the BCCs are frequently associated with a non-aggressive histologic subtype. Treatment usually involves complete excision of the BCC. Tumor recurrence was uncommon following successful treatment of the primary neoplasm.
Ferrofluid-associated Cutaneous Dyschromia: Discoloration of Hand and Fingers Following Accidental Exposure to Ferromagnetic Fluid. - The Journal of clinical and aesthetic dermatology
Ferrofluid is a colloidal suspension that usually consists of surfactant-coated nanoparticles of magnetite (Fe3O4) in a carrier liquid. Ferromagnetic fluid forms spikes when the liquid is exposed to a magnetic field.The authors describe a man who developed temporary discoloration of his right palm and fingers after accidental cutaneous contact with ferrofluid and discuss some of the current and potential applications of this unique liquid.A 28-year-old man was evaluating the effects of magnetic fields using ferrofluid. He performed a modification of the "leaping ferrofluid" demonstration in which he held a superstrong (14,800 gauss magnetic field strength) N52 rare earth neodymium magnet in his palm and slowly lowered that hand over an open bowl that was filled with ferrofluid.As the magnet approached the liquid, the ferrofluid became magnetized. The liquid leaped from the bowl and contacted not only the magnet, but also the palmar surface of his hand and fingers, resulting in a black-brown dyschromia of the affected skin. The discoloration completely resolved after two weeks without any adverse sequellae.Ferrofluid has numerous current and potential applications; in addition to being of value educationally and aesthetically (after being subjected to magnetic fields), it is also utilized for audio loudspeakers, medical innovations (such as a component of either a research tool, a diagnostic aid, or a treatment modality), and seals. Although the authors' patient did not experience any acute or chronic toxicity from his cutaneous exposure to ferrofluid, conservative follow-up for individuals who experience skin contact with ferromagnetic fluid may be appropriate.
My personal experiences at the BEST Medical Center: A day in the clinic-the afternoon. - Clinics in dermatology
Dr. Ida Lystic is a gastroenterologist who recently began her new faculty position at the BEST (Byron Edwards and Samuel Thompson) Medical Center. After completing her MD degree at the prestigious Harvey Medical School (recently renamed the Harvey Provider School), she did her internal medicine residency and fellowship training at the OTHER (Owen T. Henry and Eugene Rutherford) Medical Center. Her morning in gastroenterology clinic was highlighted by: (1) being reprimanded by the clinic nurse manager for a patient who not only arrived early, before clinic had opened, but also neglected to schedule the anesthesiologist for his colonoscopy; (2) the continued challenges of LEGEND (also known as Lengthy and Excessively Graded Evaluation and Nomenclature for Diagnosis by her colleagues), the new electronic medical record system after the BEST discarded the SIMPLE (Succinct Input Making Patient's Lives Electronic) system; (3) a nurse's interruption of an office visit-once the egg timer on the examination room door ran out-because she had exceeded the allocated time for the appointment; and (4) her chairman's unanticipated arrival in the clinic to visit with the clinic nurse manager. In addition to seeing her patients, Dr. Lystic's afternoon is occupied by attending a LOST (Laboratory OverSight and Testing) Committee meeting and a visit from a wayfinding and signage specialist to depersonalize the doorpost plaques of the examination rooms. Her day ends with a demeaning email from her chairman regarding the poor results of the most recent patient satisfaction survey and being personally held accountable to develop solutions to improve not only her performance but also that of the clinic. Although Dr. Ida Lystic and the gastroenterology clinic at "the BEST Medical Center" are creations of the authors' imagination, the majority of the anecdotes mentioned in this essay are based on individual patients and their physicians, clinics in medical centers and their administration, and actual events, though details have been modified to protect the guilty.Copyright © 2016 Elsevier Inc.

Fibroepithelioma of Pinkus Revisited. - Dermatology and therapy
Fibroepithelioma of Pinkus (FeP) is considered a variant of basal cell carcinoma (BCC); however, in the past 20 years, some researchers have argued for its classification as a trichoblastoma. Recently, use of a new immunostaining marker and further dermoscopic characterization of FeP have advanced the debate about its proper classification.A review of the evidence for and against classification of FeP as BCC or trichoblastoma is presented.Using PubMed, the term FeP was searched and relevant citations were assessed. Additional relevant articles were identified from references of key papers.FeP shares characteristics of both trichoblastoma and BCC.Derived from the same cell type, BCC and trichoblastoma may be best considered as representing opposite ends of a spectrum of differentiation, with FeP deserving an intermediate classification.
Amitriptyline-induced cutaneous hyperpigmentation: case report and review of psychotropic drug-associated mucocutaneous hyperpigmentation. - Dermatology online journal
Several drugs can be associated with hyperpigmentation of mucosa or skin. They include antibiotic, antimalarial, antineoplastic, and psychotropic medications.To describe a 42-year-old woman with amitriptyline-associated photo-distributed hyperpigmentation and to review psychotropic drug-induced hyperpigmentation of the skin.The features of a woman with amitriptyline-induced hyperpigmentation are presented. Using PubMed, the following terms were searched and relevant citations were assessed and discussed for context: amitriptyline, chlorpromazine, citalopram, desipramine, drug-associated, drug-induced, Fontana Masson, hyperpigmentation, imipramine, melanin, melanophages, mirtazapine, phenytoin, psychotropic, sertraline, thioridazine, tricyclic antidepressant.Photo-distributed hyperpigmentation on the upper back of a woman developed six and a half years after initiation of amitriptyline therapy. Biopsy of the affected area showed pigment-laden melanophages and intradermal melanin deposition.Psychotropic drugs associated with cutaneous hyperpigmentation include amitriptyline, chlorpromazine, citalopram, desipramine, imipramine, mirtazapine, phenytoin, sertraline, and thioridazine. The hyperpigmentation may initially appear many years after starting the medication. Pathology typically shows melanophages and melanin in the dermis. Fontana Masson stain confirms the presence of melanin; Perl stain for hemosiderin or iron is negative. Discontinuation of the drug may result in spontaneous improvement. Further studies are needed to better understand the role of Q-switched laser in treating drug-induced hyperpigmentation.
My personal experiences at the BEST Medical Center: A day in the clinic-the morning. - Clinics in dermatology
Dr. Ida Lystic is a gastroenterologist who trained at the OTHER (Owen T. Henry and Eugene Rutherford) Medical Center, after having completed her MD degree at the prestigious Harvey Medical School (recently renamed the Harvey Provider School). She accepted a faculty position at the BEST (Byron Edwards and Samuel Thompson) Medical Center. Dr. Lystic shares her experiences on a typical morning in gastroenterology clinic. Although her clinic start date was delayed by 2 months after becoming sick following a mandatory flu shot and having to complete more than 70 hours of compliance training modules, she is now familiar with the BEST system. Clinic scheduling priorities include ensuring that the staff can eat lunch together and depart at 5:00 pm. It is a continual challenge to find time to complete the electronic medical record after BEST changed from the SIMPLE (Succinct Input Making Patients Lives Electronic) system to LEGEND (referred to as Lengthy and Excessively Graded Evaluation and Nomenclature for Diagnosis by her colleagues). To maintain clinic punctuality, a compliance spreadsheet is e-mailed monthly to the Wait Time Committee. Their most recent corrective action plan for tardy physicians included placing egg timers on the doors and having nurses interrupt visits that exceed the allotted time. Administrative decisions have resulted in downsizing personnel. Patients are required to schedule their own tests and procedures and follow-up appointments-causing low patient satisfaction scores; however, the money saved lead to a large year-end bonus for the vice president of BEST Efficiency, who holds "providers" accountable for the poor patient experience. Although Dr. Ida Lystic and the gastroenterology clinic at "the BEST Medical Center" are creations of the authors' imagination, the majority of the anecdotes are based on actual events.Copyright © 2016 Elsevier Inc.

Amyopathic Dermatomyositis: A Concise Review of Clinical Manifestations and Associated Malignancies. - American journal of clinical dermatology
Amyopathic dermatomyositis is a rare, idiopathic, connective tissue disease that presents with dermatologic lesions of classic dermatomyositis but lacks the myopathy of this disease. Cutaneous manifestations may include Gottron's sign, heliotrope rash, and characteristic patterns of poikiloderma. There is a substantial risk for developing interstitial lung disease or malignancy in patients with amyopathic dermatomyositis. A literature review of amyopathic dermatomyositis was performed using the PubMed medical database. The key features of amyopathic dermatomyositis, including autoantibodies, clinical presentation and dermatologic manifestations, epidemiology, history, associated malignancies, management, and pathogenesis, are summarized in this review. Cancer (solid tumor) (73/79, 89 %) and hematologic malignancies (9/79, 11 %) were reported in 79 patients, with three patients having more than one malignancy. In addition, there were six patients with amyopathic dermatomyositis who had tumor of unknown primary, and eight patients with cancer-associated amyopathic dermatomyositis for whom no additional details were provided. From the group of 73 tumors for whom primary origin and sex were available, malignancy of the genitourinary organs (24/73, 33 %), aerorespiratory organs (15/73, 21 %), and breast (14/73, 19 %) were the most commonly observed solid organ tumors. Tumors of the genitourinary organs (15/48, 31 %) and breast (14/48, 29 %) were the most frequent neoplasms in women, accounting for 29 of 48 (60 %) cancers, with the most common sites being breast (14/48, 29 %), ovary (8/48, 17 %), and cervix or uterus (5/48, 10 %). In men, tumors of the aerorespiratory (9/25, 36 %) and genitourinary (9/25, 36 %) tracts were the most common neoplasms, accounting for 72 % (18/25) of cancers; the most common sites of primary malignancy were nasopharyngeal (6/25, 24 %), bladder (4/25, 16 %), and either colorectal, lung or prostate cancer (three cancers each, 12 %). In summary, the search for an undiagnosed associated malignancy in patients with amyopathic dermatomyositis should focus towards the organs most frequently affected. Similar to classic dermatomyositis, ovarian and nasopharyngeal cancers are also common in amyopathic dermatomyositis. However, in contrast to lung cancer, which is the most frequent malignancy associated with classic dermatomyositis, breast cancer was the most common type of malignancy reported in patients with amyopathic dermatomyosotis.
Red Dot Basal Cell Carcinoma: An Unusual Variant of a Common Malignancy. - Journal of drugs in dermatology : JDD
Red dot basal cell carcinoma is a distinct but rare subtype of basal cell carcinoma (BCC). It presents as a red macule or papule; therefore, in most cases, it may easily be mistaken for a benign vascular lesion, such as a telangiectasia or angioma.
A red dot BCC in an older woman is described. Clinical and histological differences between red dot BCCs and telangiectasias are described.
A 72-year-old woman initially presented with a painless red macule on her nose. Biopsy of the lesion established the diagnosis of a red dot BCC. Pubmed was searched for the following terms: angioma, basal cell carcinoma, dermoscope, diascopy, red dot, non-melanoma skin cancer, telangiectasia, and vascular. The papers were reviewed for cases of red dot basal cell carcinoma. Clinical and histological characteristics of red dot basal cell carcinoma and telangiectasias were compared.
Red dot BCC is an extremely rare variant of BCC that may be confused with benign vascular lesions. Although BCCs rarely metastasize and are associated with low mortality, they have the potential to become locally invasive and destructive if left untreated. Thus, a high index of suspicion for red dot BCC is necessary.

HCK is a survival determinant transactivated by mutated MYD88, and a direct target of ibrutinib. - Blood
Activating mutations in MYD88 are present in ∼95% of patients with Waldenström macroglobulinemia (WM), as well as other B-cell malignancies including activated B-cell (ABC) diffuse large B-cell lymphoma (DLBCL). In WM, mutated MYD88 triggers activation of Bruton tyrosine kinase (BTK). Ibrutinib, a pleiotropic kinase inhibitor that targets BTK, is highly active in patients with mutated MYD88. We observed that mutated MYD88 WM and ABC DLBCL cell lines, as well as primary WM cells show enhanced hematopoietic cell kinase (HCK) transcription and activation, and that HCK is activated by interleukin 6 (IL-6). Over-expression of mutated MYD88 triggers HCK and IL-6 transcription, whereas knockdown of HCK reduced survival and attenuated BTK, phosphoinositide 3-kinase/AKT, and mitogen-activated protein kinase/extracellular signal-regulated kinase signaling in mutated MYD88 WM and/or ABC DLBCL cells. Ibrutinib and the more potent HCK inhibitor A419259, blocked HCK activation and induced apoptosis in mutated MYD88 WM and ABC DLBCL cells. Docking and pull-down studies confirmed that HCK was a target of ibrutinib. Ibrutinib and A419259 also blocked adenosine triphosphate binding to HCK, whereas transduction of mutated MYD88 expressing WM cells with a mutated HCK gatekeeper greatly increased the half maximal effective concentration for ibrutinib and A419259. The findings support that HCK expression and activation is triggered by mutated MYD88, supports the growth and survival of mutated MYD88 WM and ABC DLBCL cells, and is a direct target of ibrutinib. HCK represents a novel target for therapeutic development in MYD88-mutated WM and ABC DLBCL, and possibly other diseases driven by mutated MYD88.© 2016 by The American Society of Hematology.
Molluscum contagiosum of the eyelid: case report in a man receiving methotrexate and literature review of molluscum contagiosum in patients who are immunosuppressed secondary to methotrexate or HIV infection. - Dermatology online journal
Molluscum contagiosum is a benign viral infection of the skin. Lesions typically present as dome-shaped, flesh-colored, umbilicated papules that range in size from 1 to 5 millimeters in diameter. They are usually asymptomatic, but can become tender or pruritic. Children and immunocompromised adults, including individuals being treated with immunosuppressive drugs, are most susceptible to infection. Single or multiple lesions most commonly appear on the extremities, face, genitals, and trunk. However, albeit rarely, molluscum contagiosum may also develop at other sites, including the eyelids.We describe the clinical and pathologic findings of a man who developed molluscum contagiosum of the eyelid while receiving methotrexate. We also review the characteristics of other patients with molluscum contagiosum acquired either during treatment with methotrexate or associated with human immunodeficiency virus (HIV) infection and summarize the unusual sites of presentation for the viral lesions in these individuals.The features of a man receiving methotrexate who developed molluscum contagiosum of the eyelid are presented. Using PubMed, the following terms were searched and relevant citations assessed: adalimumab, contagiosum, Enbrel, etanercept, Humira, infliximab, methotrexate, molluscum, Remicade, TNF alpha, and tumor necrosis factor alpha. In addition, the literature on methotrexate treatment and molluscum contagiosum is reviewed. Several small papules were observed on the eyelid of a 24-year-old man who had been receiving methotrexate and adalimumab (Humira) for the treatment of Crohn disease. The lesions were removed by shave biopsy. Microscopic examination revealed epidermal hyperplasia composed of keratinocytes filled with large eosinophilic intracytoplasmic inclusions. Based on correlation of the clinical presentation and histopathologic findings, a diagnosis of molluscum contagiosum was established. The patient applied mupirocin 2% ointment to the biopsy sites, which subsequently healed without complication or recurrence.Molluscum contagiosum is a benign viral papular eruption that frequently affects children and immunocompromised adults. Patients treated with immunosuppressive agents, such as methotrexate, have a heightened risk of developing molluscum contagiosum lesions. It remains to be determined whether adjunct therapy with a tumor necrosis factor alpha inhibitor increasesthe risk of this viral infection. Diagnosis can usually be established by clinical presentation, although a biopsy is sometimesrequired to exclude other conditions. Molluscum contagiosum is generally self-limiting and often resolves spontaneously within18 months. However, topical (cantharidin) or locally destructive (curettage, cryotherapy, and/or laser) therapy may be indic tedfor patients who are concerned about persistent lesions and for children who are particularly susceptible to autoinoculation.
