A left parietal skin tumor showing rapid enlargement in a 33-year-old woman was excised. The cut surface of the skin revealed a whitish tumor 4 cm in diameter associated with a cyst formation. Histologically, the whitish tumor was mucinous carcinoma in which large clear cells were conspicuous. Because nests of clear cell hidradenoma (CCH) were seen in the cyst wall, this carcinoma was diagnosed as malignant CCH presumably arising from a part of benign CCH. Malignant CCHs are thought to be malignant from their onset. Those proved to have developed from benign CCHs like the present case are extremely rare.
一名33岁女性的左顶叶皮肤肿瘤迅速增大，遂将其切除。皮肤的切面显示出一个直径4厘米的白色肿瘤，伴有囊肿形成。组织学上，该白色肿瘤为黏液癌，其中大的透明细胞很明显。由于在囊肿壁中可见透明细胞汗腺瘤（CCH）巢，因此该癌被诊断为可能起源于部分良性CCH的恶性CCH。恶性CCH被认为从发病起就是恶性的。像本病例这样被证实由良性CCH发展而来的情况极为罕见。
