Abstract
BACKGROUND
Histiocytoses patients present with highly heterogeneous clinical and histopathological pictures requiring multidisciplinary management. Mixed histiocytosis is a recently described group of syndromes defined by the histological overlap of Langerhans cell histiocytosis and other histiocytic proliferations that include three clinically and prognostically different conditions (i.e., Type-1-3 mixed histiocytosis).
CASE REPORT
We describe a 10 year-old boy with unifocal (type-3) mixed histiocytosis - Langerhans cell histiocytosis combined with a lesion with features intermediate between Rosai-Dorfman disease and reticulohistiocytosis. Sixty months after excision, the child is disease free.
DISCUSSION
Cutaneous type-3 mixed histiocytosis (Langerhans cell histiocytosis with Rosai-Dorfman disease/reticulohistiocytosis) may occur in older childhood, be unifocal, and be cured by surgical excision.
