A case report of langerhans histiocytosis presenting sequentially over a 21-year period with Letterer-Siwe disease, hand-Schuller-Christian disease and eosinophillic granuloma of bone.

摘要

Langerhans cell histiocytosis (LCH) is a very rare disorder, and usually considered a disease of childhood. The adult form of LCH is even rare, and in some case may be considered to represent delayed presentation of a pathologic process beginning in childhood. This case report highlights the range of presentations of LCH possible even in a single patient, and supports the contention that some adult LCH cases may be due to delayed presentation of childhood LCH.
