A 39-year-old man presented with painless scrotal swelling for 2 months. He denied any asbestos exposure but claimed to work with wall and ceiling plaster. Physical exam revealed a large right scrotum which transilluminated. Scrotal ultrasonography revealed a large right hydrocele and a polypoidal mass along the anterior wall of the scrotum. MRI of the abdomen and CT of the chest showed no metastases. He underwent a right inguinal scrotal exploration and wide excision of tunica vaginalis and a partial epididymectomy. Pathology revealed well-differentiated papillary mesothelioma of the tunica vaginalis. The patient was discharged following surgery and had an uneventful recovery.
