Abstract PDF: Angiomatoid fibrous histiocytoma is a rare mesenchymal neoplasm of uncertain cell lineage with indeterminate behavior, hallmarked by EWSR1 translocations. This tumor typically arises in the subcutaneous or deep soft tissues and is composed of bland to mildly atypical histiocytoid cells with frequent intralesional hemorrhagic pseudocystic spaces. It affects both children and adults, without a significant sex predilection. Histologically, the tumor may be mistaken for a lymph node given the apparent predilection for node-bearing sites as well as the brisk lymphoid cuff featuring germinal centers. Surgical excision is often curative, with local recurrence occurring occasionally and metastasis only very rarely. A possible relationship to molecularly related entities arising primarily within the thoracic cavity and intracranial compartment has been proposed, although this association remains incompletely understood.
