A rare cause of solitary rib lytic lesion in adult – A case report

Abstract

Langerhans cell histiocytosis (LCH) is characterized by the proliferation of Langerhans cells, which can occur in single or multiple organ systems. The most common sites of involvement include skeletal system, central nervous system, lungs, skin, and lymph nodes. LCH involving the rib is one of the rarest site among adults. Herein, we report a case of a 40-year-old man with solitary LCH in posterior aspect of 4th rib.
