Question:

Reportability--Heme & Lymphoid Neoplasms: Is self-healing Langerhans cell histiocytosis (LCH) of the skin reportable?

Discussion:

Answer:

Updated May 2026

Self-healing LCH usually happens when the disease is confined to the skin. The term "self-healing" means that the neoplasm regressed without treatment. This is a known phenomenon.

This is a reportable primary as Langerhans cell histiocytosis (LCH) [9751/3] for years 2010-2020.

Starting in 2021, this would be 9751/1 and only be reportable if it occurred in the CNS.
