Large Epidermoid Cyst of the Breast: Report of a Case

類表皮囊腫一般位於身體軀幹皮膚下層，大多是小型，且沒有症狀。偶爾也會在乳房皮膚下層甚至於乳房組織內被發現，在影像檢查上有時不易與惡性腫瘤區分。尤有甚者，曾有些罕見的潛在惡性變化病例被報告。我們報告一位39歲女性在左側乳房罹患一顆腫塊，這無痛性腫塊節年內逐漸增大到直徑超過10公分的大小並且引起左側腋下淋巴結腫大，臨床上頗似惡性腫瘤。我們爲此病患進行腫瘤切除手術並且收集了乳房超音波、乳房攝影、手術標本及病理等照片。值得一提的是在回顧相關文獻後，此病例應是目前被報告發生於乳房內最大的類表皮囊腫。乳房的類表皮囊腫是少見的乳房良性疾病，但它有時於臨床上不易與惡性腫瘤區分並且確有罕見的潛在惡性變化危險，所以手術切除是合適的治療方式。

Epidermoid cysts are located mainly in the subcutaneous layer of the trunk and are often small and asymptomatic. When they develop in the breast parenchyma they are a rare benign condition, yet have the potential for malignancy. We report on a 39 year-old female who presented with a large protruding lump from her left breast. The mass grew up to more than 10 cm in diameter during the period of five years. Enlarged left axillary lymph nodes were noted also. A malignant tumor was suspected based on the imaging and clinical features. She underwent tumor excision and an epidermoid cyst was confirmed by histopathologic assessment. We collected the breast images, the surgical specimen photographs and reviewed the literature. To the best of our knowledge, the cyst reported here is the largest of the epidermoid cysts arising within the breast that have been reported. Although at times, the epidermoid cyst is difficult to distinguish from a malignant tumor, surgical excision is justified because of its potential for malignancy.
