Abstract

The expression of p16INK4a has been reported to be a significant marker for malignant transformation of epidermal tumors. However, little is known about sweat gland tumors. We examined the immunohistological expression of p16INK4a in benign and malignant sweat gland tumors. The ductal and acrosyringial portion of normal eccrine glands were positively stained with p16INK4a while it was negative in the normal epidermis. Moderate to strong expression of p16INK4a was found in 16 of 17 eccrine poromas, 4 of 5 hidradenomas, 3 of 3 syringocystadenoma papilliferums, 2 of 2 mixed tumors, and 3 of 3 syringomas. The p16INK4a expression was observed focally or diffusely in 4 of 4 porocarcinomas, 4 of 4 apocrine carcinomas and 12 of 17 extramammary Paget's diseases. We conclude that the p16INK4a expression is not a good marker for dictating malignant transformation of sweat gland tumors.
