Multinucleate cell angiohistiocytoma (MCAH) is an uncommon benign fibrohistiocytic and vascular proliferation, which usually occurs as slow-growing grouped reddish-brown to purple papules and nodules on the distal extremities or face. Patients with generalized MCAH are extremely rare and to our knowledge, there are no more than 11 cases reported previously in the medical literature.
