The accessory breast is composed of residual glandular mammary tissue that persists after normal embryonic development. The entity is so rare that it is easily neglected in the diagnosis of disease.
We report a 24-year-old virgin Persian woman with a left-sided vulvar mass and no pain or discomfort until shortly before her presentation at our department. Ectopic breast tissue in the vulva was diagnosed. We performed wide local resection of the lesion. Pathological investigation of the lesion confirmed the presence of ectopic breast tissue with secretory changes. She had no specific developmental abnormalities and had no relevant family history. She was followed up for 10 months and had recovered fully by this time.
Accessory breast tissue should be considered as a diagnosis when a mass is seen along the embryonic milk line, especially if the clinical findings reveal changes in the mass accompanied by changes in sex hormones.
副乳腺由正常胚胎发育后残留的乳腺组织构成。由于这种实体非常罕见，因此在疾病诊断中很容易被忽视。
我们报告了一例 24 岁的波斯处女，她左侧外阴有一个肿块，在就诊前没有任何疼痛或不适。诊断为外阴异位乳腺组织。我们对病变进行了广泛的局部切除。病变的病理检查证实存在具有分泌变化的异位乳腺组织。她没有特定的发育异常，也没有相关家族史。她随访了 10 个月，此时已完全康复。
当沿着胚胎乳线出现肿块时，应考虑副乳腺组织的诊断，特别是如果临床发现肿块伴有激素变化。
