Well Differentiated Papillary Mesothelioma (WDPM) is an uncommon neoplasm of the paratesticular area usually presents as hydrocele. Here we report a rare case of benign papillary mesothelioma of the tunica vaginalis presented as hydrocele with singly polypoidal grossly papillary lesion with multiple foci in the hydrocele sac. Histologically tumor shows branching papillary structures with fibro vascular core and cytologically bland nuclei without any mitosis, necrosis or area of invasion. In addition histochemistry is done to differentiate it with other papillary neoplasm. WDPM must be distinguished from the aggressive lesion to avoid unnecessary treatment.
