RESUMO
AIM: To present current and new knowledge on congenital self-healing reticulohistiocytosis, a benign variant of cutaneous Langerhans cell histiocytosis presenting with skin lesions in the neonatal period. METHODS: We describe and photo document two cases of this rare disease and review the literature. RESULTS: Only few newborns have acute access to a neonatal dermatologist, and we demonstrate how the spontaneous cutaneous involution may happen even prior to the first dermatological assessment. As no sole criterion can reliably distinguish the self-healing form from disseminated disease, multidisciplinary assessment and follow-up are essential. CONCLUSION: Our data document how easily the diagnosis congenital self-healing reticulocytosis may be missed and emphasize the importance and value of instant clinical photographing at the neonatal unit and the use of teledermatology whenever congenital self-healing reticulohistiocytosis is suspected.
