Telangiectasia Macularis Eruptiva Perstans of the Scalp Mimicking Angiosarcoma.

We present a case of a 74-year-old man with marked photodamage who was ultimately diagnosed with telangiectasia macularis eruptiva perstans (TMEP) of the scalp. The diagnosis was made more difficult because of the clinical and histological similarity of this case with an early angiosarcoma. TMEP is a benign and indolent rare subtype of cutaneous mastocytosis presenting clinically with red-brown telangiectatic macules, usually symmetrically distributed over the trunk and extremities.

Computerized Image Analysis of Tumor Cell Nuclear Morphology Can Improve Patient Selection for Clinical Trials in Localized Clear Cell Renal Cell Carcinoma.

Background: Clinicopathological scores are used to predict the likelihood of recurrence-free survival for patients with clear cell renal cell carcinoma (ccRCC) after surgery. These are fallible, particularly in the middle range. This inevitably means that a significant proportion of ccRCC patients who will not develop recurrent disease enroll into clinical trials.
