社会的な問題のために適切な治療や観察を行えなかった巨大精巣腫瘍（病期Iセミノーマ）の2例

Abstract

The first case was in a 39-year-old man who complained of painless, left hemiscrotal swelling. The patient's serum β human chorionic gonadotropin (β-hCG) was elevated. A chest X-ray and computerized tomography (CT) did not reveal any abnormal findings. The patient underwent left high orchiectomy. The tumor weighed 440 g, and was pathologically diagnosed as a seminoma. The patient chose surveillance as the management strategy. Five months after the operation, the patient stopped attending his periodic checkups. After 21 months, the patient complained of abdominal distention. A CT showed a para-aortic lymph node mass. The patient achieved a complete response following chemotherapy with etoposide and cisplatin for 4 cycles. Three months after the adjuvant chemotherapy, hospital visits stopped again due to financial difficulties. The second case was in a 36-year-old man who complained of painless, right hemiscrotal swelling and difficulty in walking. Clinical examination revealed an adult-head-sized testicular tumor with elevation of serum lactic dehydrogenase (LDH) and β-hCG. A chest X-ray and abdominal CT did not reveal any abnormal findings. Despite a recommendation that the patient undergo immediate orchiectomy, the patient did not undergo surgery due to his unstable lifestyle. After 1 month, the patient presented with more difficulty in walking. The patient underwent right high orchiectomy. The tumor weighed 1, 926 g, and was pathologically diagnosed as a seminoma. The patient chose surveillance. There has been no recurrence for 19 months postoperatively.
