Squamous cell carcinoma (SCC) of the breast is an extremely rare form of cancer, accounting for approximately 0.04% of all malignant breast tumors. To date, only a limited number of cases of SCC of the breast have been reported, and most of them presented like the usual breast carcinomas.
A 39-year-old woman presented with a large breast abscess and signs of sepsis. After surgical debridement of the lesion, histopathological examination of the abscess capsule revealed the presence of SCC of the breast. The definitive treatment for the tumor consisted of modified radical mastectomy with resection of the residual lesion in the right breast.
This unusual case illustrates how an apparently benign disorder such as a breast abscess might be related to a clinically occult malignancy. A review of the literature on SCC of the breast is presented.
乳腺鳞状细胞癌（SCC）是一种极其罕见的癌症形式，约占所有乳腺恶性肿瘤的0.04%。迄今为止，仅有有限数量的乳腺SCC病例被报道，且其中大多数表现类似常见的乳腺癌。
一名39岁女性出现一个大的乳腺脓肿及败血症体征。对病变进行手术清创后，脓肿包膜的组织病理学检查显示存在乳腺SCC。该肿瘤的确定性治疗包括改良根治性乳房切除术及切除右侧乳房的残留病变。
这个不寻常的病例说明了一种看似良性的疾病，如乳腺脓肿，可能与临床上隐匿的恶性肿瘤有关。本文对乳腺SCC的文献进行了综述。
