We report a case of intratesticular endometrioid papillary cystadenocarcinoma. A 73-year-old man was admitted for a painless right scrotal swelling. Ultrasonography and computed tomography revealed a large cystic mass in the right testis. Right scrotum puncture revealed xanthochromic fluid with negative cytology. Three months later, follow-up computed tomography showed enlargement of the cystic mass. Right high orchiectomy was performed because a testicular malignancy was suspected. The pathological diagnosis was endometrioid papillary cystadenocarcinoma, and the cells were strongly positive for the estrogen and progesterone receptors. Testicular neoplasms resembling common ovarian-type epithelial tumors are very rare. This is the first report of endometrioid papillary cystadenocarcinoma of the testis.
我们报告一例睾丸内子宫内膜样乳头状囊腺癌。一名 73 岁男性因右侧阴囊无痛性肿胀入院。超声和 CT 显示右侧睾丸内有一个大的囊性肿块。右侧阴囊穿刺显示黄染液体，细胞学检查为阴性。3 个月后，随访 CT 显示囊性肿块增大。由于怀疑睾丸恶性肿瘤，行右侧高位睾丸切除术。病理诊断为子宫内膜样乳头状囊腺癌，细胞对雌激素和孕激素受体呈强阳性。类似于常见卵巢型上皮性肿瘤的睾丸肿瘤非常罕见。这是首例睾丸子宫内膜样乳头状囊腺癌的报告。
