Langerhans cell sarcoma

ORPHA:86897Disease

What it is

A rare dendritic cell tumor characterized by an aggressive, high-grade neoplasm derived from Langerhans cells, most commonly extranodal and multifocal, involving the skin and underlying soft tissue, as well as lung, liver, spleen, and bone. Primary nodal involvement is seen in a minority of patients. Immune-phenotyping and the presence of Birbeck granules on ultrastructural examination reveal the Langerhans cell derivation of the neoplastic cells. Prognosis is generally poor.
