Mogamulizumab is a monoclonal antibody against CCR4 approved for treatment mycosis fungoides (MF) and Sézary syndrome (SS). Mogamulizumab-associated rash (MAR) difficult to differentiate from cutaneous MF or SS, which can lead unnecessary discontinuation of drug use because concern severe reaction incorrect presumption disease relapse progression in the skin.To examine most common clinical presentations MAR patients with SS diagnostic management challenges.This retrospective case series...

Rash is one of the most common adverse events observed with mogamulizumab, an anti-C-C chemokine receptor 4 monoclonal antibody approved for previously treated mycosis fungoides (MF) and Sezary syndrome (SS). Given nonspecific clinical presentations this rash, histopathologic distinction from MF/SS critical informing management. We performed a comprehensive characterization findings in mogamulizumab-associated rash (MAR) integration high-throughput sequencing T-cell (TCR) genes. Fifty-two...

Importance Cutaneous squamous cell carcinoma (CSCC) risk stratification is central to management, and physicians rely on tumor staging systems estimate risk. The Brigham Women’s Hospital (BWH) T system predicts based 4 factors (RFs). However, stage not precisely associated with the number of RFs, as BWH T2b includes CSCCs 2 3 RFs. Objective To determine how RF recurrence, metastasis, disease-related death. Design, Setting, Participants This retrospective multination cohort study diagnosed...

Immunotherapy with immune checkpoint inhibitors that target the programmed cell-death receptor 1 (PD-1) is increasingly used for patients advanced or metastatic melanoma, non–small cell lung cancer, renal carcinoma, Hodgkin lymphoma, and urothelial carcinoma. Cutaneous adverse events occur during treatment these agents include pruritus, vitiligo, lichenoid dermatitis, psoriasiform and, more recently, bullous pemphigoid other autoimmune blistering disease.1-8 Interestingly, radiation therapy...

PURPOSE To evaluate the feasibility of administering three doses neoadjuvant atezolizumab before curative surgical resection in patients with advanced cutaneous squamous cell carcinoma (cSCC). PATIENTS AND METHODS This single-arm phase II trial included cSCC head and neck stage III or IV disease, lesions for which standard therapy would incur an unacceptable morbidity. Patients received up to at a fixed dose 1,200 mg every 21 days undergoing resection. The primary end point was percentage...

Objective: To utilize 3-D modeling techniques to better characterize geometric deformations of the supra-aortic arch branch vessels and descending thoracic aorta after endovascular aortic repair. Methods: Eighteen patients underwent repair either type B dissection (n = 10) or aneurysm 8). Computed tomography angiography was obtained pre- postprocedure, models were constructed. Branch angle curvature metrics ascending aorta, arch, stented lumen calculated both at postintervention. Results:...
