A poroma is usually described as a benign neoplasm arising from ductal epithelium of eccrine gland. However, in recent years there have been several reports on poromas featuring with combined sebaceous, follicular, and ductal differentiation, and thus establishment of this separate disease entity, "apocrine poroma" may well be justified considering the common embryologic origin of folliculosebaceous-apocrine unit. In our case, the tumor presented as a dark red nodule on the pubic area, being revealed as poroid neoplasm with folliculosebaceous components embedded in the lobules. Immunohistochemically, poroid cells stained with lysozyme. Taking the immunohistochemical staining results as well as the histopathologic findings of folliculosebaceous differentiation into consideration, we have concluded that this tumor is a case of an "apocrine poroma".
