Adenomatoid tumors are regarded as distinctive benign mesothelial neoplasm of the paratesticular region. We present a case report of an adult male who presented with right testicular swelling and pain, which was reported as paratesticular tumor on ultrasound examination. The cut-section of the orchidectomy specimen showed a well-circumscribed nodule with wide areas of necrosis. Microscopically, the lesion was composed of tubules that were lined by flat to cuboidal cells with round to oval nuclei and abundant vacuolated cytoplasm which were diagnostic of adenomatoid tumor. But the associated extensive areas of coagulative necrosis and reactive changes of fibroblasts and myofibroblasts obscured the main lesion and posed diagnostic difficulty. Positivity for calretinin and cytokeratin-7 are useful for confirming the diagnosis. Infarction of an adenomatoid tumor obscures the nature of the underlying lesion and causes diagnostic challenge.
