A Solitary Variant of Congenital Self‐healing Reticulohistiocytosis: Solitary Hasimoto‐Prltzker Disease

Abstract

Four neonates had solitary, congenital, rapidly growing, spontaneously ulcerating tumors of the face, trunk, and extremities. No extracutaneous involvement was found, and all lesions spontaneously involuted. Mononuclear cells of the cutaneous infiltrate were Langerhans' cells. These findings expand the spectrum of congenital self-healing reticulohistiocytosis.
