Epidermal cysts are common cysts located cutaneously or subcutaneously in the head, neck, and trunk. However, deep epidermal cysts of the breast are very rare, and are frequently associated with traumatic implantation. We present the case of a 62-year-old woman with a palpable mass in the right breast. The patient was evaluated using mammography, ultrasound, and MRI, which uniquely characterized the mass and revealed a second mass. Histological analysis revealed fragments of an epidermoid cyst. The origin of the cysts and location deep within the breast tissue likely were due to a previous bilateral-reduction mammoplasty.
表皮样囊肿是常见的囊肿，位于头、颈和躯干的皮肤或皮下。然而，乳腺深部表皮样囊肿非常罕见，且常与创伤性植入有关。我们报告一例62岁女性，其右乳可触及肿块。对该患者进行了乳房X线摄影、超声和磁共振成像检查，这些检查独特地描绘了肿块特征并发现了第二个肿块。组织学分析显示为表皮样囊肿碎片。囊肿的起源以及位于乳腺组织深部的位置可能归因于既往双侧乳房缩小成形术。
