[A case of primary mucinous adenocarcinoma of the scrotal contents].

A 48-year-old man consulted our hospital complaining of painless swelling of the left scrotal contents that had gradually increased for 5 years. Serum LDH, alpha-fetoprotein and HCG were within normal ranges. The ultrasonography showed heterogeneous echogram including high-echogenic spots and relatively a low-echogenic hydrocele. Left high orchiectomy was performed and the removed tissue was 24 x 16 x 15 cm in size, which had large cystic cavity filled with cloudy and deep-green mucin. Pathological diagnosis was mucinous adenocarcinoma. Postoperatively analyzed serum CEA, CA19-9 and PSA were within normal ranges. Systemic X-ray examinations, such as lung, abdominal and pelvic CT scan, upper GI series and barium enema, did not show any abnormal SOL suggesting carcinoma. Therefore, we diagnosed this case as a primary adenocarcinoma in the scrotal contents. The patient has been observed without any adjuvant therapy since operation, but no signs of recurrence have been identified for one year and six months.
