Multiple tissue biopsies revealed fibrohistiocytic infiltration but provided an inconclusive diagnosis.

Bone marrow biopsy revealed abnormal histiocytes with multinucleated giant forms, prominent emperipolesis, active hemophagocytosis, and condensed hemosiderin deposition. Immunohistochemistry showed positive histiocytes for CD68, CD163, and partially for S-100. Molecular analysis confirmed the <i>BRAFV660E</i> mutation, establishing a diagnosis of ECD with atypical histologic features and findings overlapping with Rosai-Dorfman (mixed histiocytosis). The diagnosis was challenging due to extensive fibrosis, the lack of typical histopathologic features of ECD, in addition to concurrent involvement by Rosai-Dorfman cells (mixed histiocytosis), activated macrophages, and dense hemosiderin deposition - a morphologic characteristic not previously described in ECD.
