- Abstract
Cutaneous reactive angiomatosis is an unusual benign vascular disorder of the skin usually associated to systemic diseases. It is characterized by lobular or diffuse proliferation of small blood vessels with hyperplasia of endothelial cells, pericytes, and sometimes histiocytes. We report a 59-year-old man with asymptomatic erythematous-violaceous patches on back, palms, and elbows for 9 months. Laboratory examination revealed changes consistent with B-chronic lymphocytic leukemia. Cutaneous biopsy showed a predominantly lobular small blood vessel proliferation in dermis with pericytic hyperplasia and mild perivascular lymphoplasmacytic infiltrate. Spontaneous involution of lesions occurred after 6 months. A second biopsy performed at the beginning of clinical involution showed a less prominent vascular component with perivascular giant cells with coexpression of CD68 and CD 31. To our knowledge, this is the first case of cutaneous reactive angiomatosis with documented histopathological findings of clinical involution.
