Case report: An 86-year-old male with an epithelioid angiosarcoma of the scalp that mimicked malignant melanoma. Results: A large irregular dark grey-blue plaque with an adjacent speckled tan nodule was suggestive of a primary cutaneous malignant melanoma with adjacent in-transit metastasis. Both had a well-circumscribed growth pattern and were composed of numerous large epithelioid cells with scattered severe atypia and mitoses. The tumor was positive for S-100 protein and vimentin and negative for low- and highmolecular weight cytokeratins. However, at high power, the epithelioid cells with severe atypia were negative for S-100 protein, and abundant large epithelioid macrophages were responsible for the S-100 protein positivity. The malignant tumor cells were negative for HMB-45, positive for CD31 and Factor VIII-related antigen, and focally positive for CD34. A focus of infiltrative, classical angiosarcoma with irregular vascular channels lined with plump, anaplastic endothelial cells was then found deep to the epithelioid tumor. Conclusions: Macrophage rich epithelioid angiosarcoma demonstrates abundant S-100 protein-positive epithelioid macrophages. This subset of epithelioid angiosarcoma may mimic malignant melanoma and may present as a pitfall in diagnosis.展开更多

Design: Monocenter, cross-sectional study. Setting: The Skin Oncology Program, Department of Dermatology, and the Photopheresis Unit of Boston Medical Center. Patients: A total of 22 adult patients with confirmed CTCL. Main Outcome Measures: (1) Evaluation of general oncologic and skin disease-specific HRQOL using, respectively, the Functional Assessment of Cancer Therapy-General (FACT-G) and Skindex-29 profiles; (2) assessment of HRQOL association with disease stage (early stage, IA-IIA; late stage, IIB-IVB). Results: Patients with more advanced CTCL stages reported more effects on general health (FACT-G), particularly in the physical, emotional, and functional domains (P < .05). Patients with early-stage CTCL reported better skin-specific HRQOL overall (Skindex-29; P=.002) and for each specific domain than did patients with late-stage disease. The Skindex-29 scales had high internal consistency, and the confirmatory factor structure was similar to that of previous studies. Conclusions: The HRQOL of patients with CTCL can be evaluated using the Skindex-29 and FACT-G instruments. Patients with more advanced stages of CTCL had lower HRQOL scores.展开更多
