Aspiration biopsy cytology of intranodal myofibroblastoma: case report with immunocytochemical analysis.
Intranodal myofibroblastoma (IM) is a recently delineated clinicopathologic entity represented by a myofibroblastic proliferation of the lymph node. It usually occurs at the groin and presents clinically as a single enlarged lymph node. Its clinical behavior is entirely benign and local excision is curative. The authors herein report a case of IM diagnosed by aspiration biopsy cytology (ABC). The main diagnostic clues to the cytologic diagnosis of this entity as well as the differential diagnosis are presented.
