title: Epithelioid malignant mesothelioma of tunica vaginalis with deciduoid features: an unusual malignancy clinically masquerading an inguinal hernia.
abstract: Paratesticular/scrotal and inguinal canal mass lesions in elderly patients may pose a diagnostic challenge to both the surgeon as well as the pathologist. In most cases, these represent hernial sacs with their contents, and true neoplasms like lipomas, rhabdomyosarcomas, and fibrous pseudotumors are infrequent. Malignant mesotheliomas arising from the tunica layers are rare cause of inguinal and paratesticular tumors. Herein, we report a case of an elderly patient who presented with an inguinal hernia which pathologically had features of deciduoid malignant mesothelioma.
