Self-healing Langerhans cell histiocytosis (Hashimoto-Pritzker disease): two Tunisian cases.

Self-healing Langerhans cell histiocytosis (SHLCH) is a rare self-limited variant of Langerhans cell histiocytosis that presents at birth or during the neonatal period. It was first described by Hashimoto and Pritzker in 1973. Subsequently, more than 70 cases have been reported in the literature. Regarding age of onset, SHLCH should be divided into congenital SHLCH and rare late-onset type. We report here two additional cases of SHLCH in Tunisian infants. We emphasize the need for long-term follow-up in such patients.
