Paraneoplastic angiomatosis: A new entity

Paraneoplastic syndromes result from tumor secretion of hormones, peptides, or cytokines or from immunologic cross reactions between malignant and normal cells. Numerous organ systems may be affected by paraneoplastic conditions, including the skin. We report 2 cases of benign cutaneous vascular proliferations occurring in the setting of malignancy and propose the term paraneoplastic angiomatosis. Case 1: A 62-year-old man with multiple comorbidities presented with a large, irregular, blanching erythematous abdominal plaque.
