Strong CA19-9 expression associated with multiple metastases in a case of apocrine carcinoma

摘要

Apocrine carcinoma is a rare malignancy of sweat glands with only 38 cases being documented since 1985 [1]. This tumor has a high potential for destructive infiltration locally, and distant metastasis caused by spreading through lymphatic and vascular systems to bone, lung, and skin [2]. Here, we report an apocrine carcinoma with elevated serum carbohydrate antigen (CA)19-9 level.
