It gives rise to a large diversity of pathologies, including those of soft tissue, which may prompt orchiectomy. We performed a 17-year search of our database for orchiectomies for a PT soft-tissue mass. In a total of 4741 orchiectomy specimens, 138 orchiectomies were performed for primary neoplastic or nonneoplastic masses of the PT soft tissue or had an incidental PT soft-tissue mass. Of these, 65.9% were neoplastic. The mean age was 40.2 years (range: &lt;1 to 87 years) and was similar for neoplastic and nonneoplastic lesions. The most common malignancies were rhabdomyosarcoma (31\/63 malignancies), liposarcoma (19\/63), and leiomyosarcoma (5\/63), with the former occurring in younger patients (average: 18.3 years). No malignancies were incidental. The most common benign neoplasm was spermatic cord lipoma (24\/28 of benign neoplasms); however, most were incidental. This was followed by leiomyoma (3\/28) and hemangioma (1\/28). The most common nonneoplastic lesions were adrenal rests (22\/47 nonneoplastic cases); however, all were incidental findings. Of 47 nonneoplastic masses, 22 prompted orchiectomy, and of these, the most common diagnosis was fibrous\/nodular periorchitis (11\/47). Of 88 nonincidental lesions, 25 were either benign neoplasms (3\/25) or nonneoplastic (22\/25). These data indicate that PT soft-tissue neoplasms prompting orchiectomy are disproportionately rhabdomyosarcomas, though these are principally in young patients. In older patients, malignancies are more frequently liposarcomas. However, almost one-third of orchiectomies performed for PT soft-tissue masses yield benign lesions, indicating an opportunity to reduce unnecessary procedures.<\/jats:p>","DOI":"10.1177\/1066896917707040","type":"journal-article","created":{"date-parts":[[2017,5,1]],"date-time":"2017-05-01T06:06:46Z","timestamp":1493618806000},"page":"480-487","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":22,"title":["Paratesticular
