title: Inflammatory myofibroblastic tumor of inguinal lymph nodes, simulating lymphoma.
abstract: Multiple enlarged lymph nodes in an elderly female patient can have varied etiologies as well as histologic pictures. We are presenting the case of a 53-year-old female who presented with inguinal lymphadenopathy with fever, which was clinically misconstrued as lymphoma. Cytology could not exclude a lymphoma. Histology led to the unusual diagnosis of inflammatory myofibroblastic tumor of lymph node in this case. Inflammatory myofibroblastic tumor of the lymph node is a rare, distinctive reactive proliferative pattern in the lymph node which involves proliferation of the connective tissue elements of the lymph node, admixed with lymphocytes, plasma cells, eosinophils, and histiocytes. Multiple etiologic agents have been suggested in existing literature. Despite extensive search, no definite attributable cause could be sought. It is now widely accepted that inflammatory pseudotumor of the lymph node is a non-neoplastic proliferation which has a benign clinical course and excellent prognosis after surgical resection.
