Society of Dermatology Hospitalists supportive care guidelines for the management of Stevens-Johnson syndrome/toxic epidermal necrolysis in adults
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening conditions with high morbidity and mortality. Supportive care management of SJS/TEN is highly variable. A systematic review of the literature was performed by dermatologists, ophthalmologists, intensivists, and gynecologists with expertise in SJS/TEN to generate statements for supportive care guideline development. Members of the Society of Dermatology Hospitalists with expertise in SJS/TEN were invited to participate in a modified, online Delphi-consensus. Participants were administered 9-point Likert scale questionnaires regarding 135 statements. The RAND/UCLA Appropriateness Method was used to evaluate and select proposed statements for guideline inclusion; statements with median ratings of 6.5 to 9 and a disagreement index of ≤1 were included in the guideline. For the final round, the guidelines were appraised by all of the participants. Included are an evidence-based discussion and recommendations for hospital setting and care team, wound care, ocular care, oral care, urogenital care, pain management, infection surveillance, fluid and electrolyte management, nutrition and stress ulcer prophylaxis, airway management, and anticoagulation in adult patients with SJS/TEN

Generalized essential telangiectasia
The pathophysiology of generalized essential telangiectasia is not well understood. Generalized essential telangiectasia is an uncommon disorder in which widespread telangiectasias of unknown cause develop without associated systemic or antecedent dermatologic disease. We report a case of generalized essential telangiectasia in an otherwise healthy 49-year-old man

Acral keratoses and squamous-cell carcinomas likely associated with arsenic exposure
Chronic arsenic exposure is known to inducepunctate keratoses with an increased risk ofprimary squamous-cell carcinoma. Drinking wateris currently the major source of arsenic exposureworldwide and is considered one of the mostsubstantial environmental carcinogens. We describethe case of a 61-year-old Hungarian woman withscattered, acral, hyperkeratotic papules and a historyof five palmoplantar squamous-cell carcinomasas well as two other extremity non-melanomaskin cancers. Prior to immigration, she had livedin a county of Southern Hungary that is known tohave elevated concentrations of inorganic arsenicin the drinking water above the World HealthOrganization’s current maximum threshold forsafety. To date, this report is the first to describethe phenomenon of palmoplantar squamouscellcarcinomas in a patient from this region andunderscores the importance of vigilant screening inthose individuals who have spent substantial time inhigh-risk regions internationally and domestically

Durable response to anti-PD-1 immunotherapy in epithelioid angiomyolipoma: a report on the successful treatment of a rare malignancy
Abstract Background Malignant angiomyolipoma is an uncommon tumor of the class of perivasciular epithelioid cell neoplasms (PEComas). These tumors are characteristically driven by deleterious mutations in the tumor suppressors TSC1 and TSC2, whose gene products typically act to inhibit mTOR. There are several cases of malignant angiomyolipoma which exhibit transient responses to mTOR inhibitors, forming the basis of current practice guidelines in malignant PEComa. However the tumors ultimately acquire resistance, and there is no well-established second-line option. Despite the increasing prevalence of immunotherapy across a wide range of solid tumors, little is known about the immune infiltrate and PD-L1 expression of angiomyolipoma. Furthermore, there is no reported case on the treatment of malignant angiomyolipoma with an immune checkpoint inhibitor. Case presentation A 38Â year-old man presented with gross hematuria and was diagnosed with renal epithelioid angiomyolipoma. Despite surgical resection, the tumor recurred and metastasized. Targeted genomic sequencing revealed a deleterious mutation in TSC2, and the patient was treated with the mTOR inihbitor everolimus. The patient went on to have a partial response but ultimately progressed. He was then treated with the anti-PD-1 immune checkpoint inhibitor nivolumab, and achieved a durable near-complete response which is ongoing after two years of treatment. Immunohistochemical staining of tumor tissue revealed strong PD-L1 expression and a brisk T-cell infiltrate. Conclusions We report on the first durable systemic treatment of malignant epithelioid angiomyolipoima with the use of PD-1 antibody nivolumab. Given the absence of prospective clinical trials in this exceedingly rare disease, particularly in the second-line setting, immune checkpoint inhibitors like nivolumab should be considered
