陰嚢内容に発症した原発性粘液腺癌の1例

Abstract

A 48-year-oldman consultedour hospital complaining of painless swelling of the left scrotal contents that hadgrad ually increasedfor 5 years. Serum LDH, α-fetoprotein andHCG were within normal ranges. The ultrasonography showedheterogeneous echogram including high-echogenic spots andrelatively a lowechogenic hydrocele. Left high orchiectomy was performedandthe removedtissue was 24×16×15cm in size, which hadlarge cystic cavity filledwith cloudy andd eep-green mucin. Pathological diagnosis was mucinous adenocarcinoma. Postoperatively analyzedserum CEA, CA19-9 andPSA 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 identifiedfor one year andsix months.
