Self-limited cutaneous Langerhans Cell Histiocytosis: A case report.

Blueberry muffin baby syndrome is a condition initially described in 1960 to classify the cutaneous manifestations of newborns with rubella. Subsequently, congenital diseases related to TORCH syndrome and blood dyscrasias have been included under this syndrome. Among the conditions associated with this syndrome is Langerhans Cell Histiocytosis, an uncommon condition with variable involvement of one or more organs, often affecting the skin. One of its forms of presentation is Hashimoto-Pritzker disease, a self-limited congenital Langerhans Cell Histiocytosis with exclusively skin involvement. First described in 1973 and with approximately 100 reported cases, its presentation as part of the Blueberry muffin baby syndrome is infrequent. Its prognosis is excellent, but long-term follow-up is required due to the possibility of relapses or subsequent visceral involvement.
