Congenital self-healing Langerhans cell histiocytosis
Hashimoto-Pritzker disease


Rare condition, about 5% of all langerhan cell histiocytosis cases, which present usually at birth or in the neonatal period, with solitary, localized to generalized papules, vesicles, or nodules on the trunk, head, palms and soles.

Within several weeks, lesions tend to involute spontaneously leaving behind hypo- or hyperpigmented macules or patches.

Abstractor Notes

Patients with this condition should be monitored carefully for relapses. Relapses often involve the bone and may progress to Letterer-Siwe disease, which is a disseminated form of Langerhans cell histiocytosis (9751/3).
