We report a case of intracystic papillary carcinoma of the breast in a 62-year-old Japanese man, who came to our hospital complaining of a right subareolar mass. Imaging diagnosis was a cyst with an intracystic component. Since repeated aspiration biopsy cytology was interpreted as a borderline lesion, no additional treatment had been given. Because he wanted the removal of the mass 14 months after his first visit, an excisional biopsy was performed under local anesthesia. Pathological examination revealed the intracystic component to be non-invasive papillary carcinoma. Although the incidence of male breast cancer is approximately 1% of all breast cancer, intracystic papillary carcinoma in the male is very rare. From a review of the literature on this disease in Japanese men, an intracystic component can often be demonstrated by ultrasound. However, it is difficult to confirm malignant cells by aspiration biopsy cytology of cyst fluid. Since some cases have a local relapse, excisional biopsy and long-term follow-up are indicated.
我们报告一例62岁日本男性的乳腺囊内乳头状癌，该患者因右乳晕下肿块前来我院就诊。影像学诊断为一个伴有囊内成分的囊肿。由于反复穿刺活检细胞学检查结果被判定为临界病变，因此未给予进一步治疗。因患者在首次就诊14个月后希望切除肿块，遂在局部麻醉下行切除活检。病理检查显示囊内成分是非浸润性乳头状癌。尽管男性乳腺癌的发病率约占所有乳腺癌的1%，但男性囊内乳头状癌非常罕见。通过回顾日本男性关于这种疾病的文献发现，超声检查通常可显示囊内成分。然而，通过囊肿液穿刺活检细胞学检查很难确诊恶性细胞。由于部分病例会出现局部复发，因此建议行切除活检及长期随访。
