A papillary hidradenoma, also termed hidradenoma papilliferum or mammary-like gland adenoma of the vulva, [1] is a rare, but nonetheless most common benign tumor that occurs in and between anal and genital regions (i.e. anogenital area) of females. [2] Hidradenoma papilliferum, also called papillary hidradenoma, is benign tumour arising from apocrine glands (see sweat gland lesions).

Understanding the Context

The lesion is a small solitary dermal or subcutaneous nodule, most commonly on the vulva. A papillary hidradenoma, also known as a mammary-like gland adenoma of the vulva or hidradenoma papilliferum is a benign tumor that is most commonly found in females between the anal and genital regions or the anogenital area. Introduction: Hidradenoma papilliferum (Papillary Hidradenoma) is an uncommon benign adnexal tumor that shows both apocrine and eccrine differentiation. It is found almost exclusively in the vulva.

Key Insights

Hidradenoma papilliferum is a benign dermal papulonodular tumor almost always found in the vulva / perianal region of women Hidradenoma papilliferum 1 is an uncommon benign tumor. Incidence unknown. Occurs in women over the age of 40. Derived from mammary-like glands in the anogenital area, 2 it was previously thought to be an apocrine gland tumor. Hidradenoma papilliferum is an uncommon benign tumour that is located in the anogenital region of middle-aged women.

Final Thoughts

They are usually only diagnosed after excision and are thought to arise from anogenital mammary-like glands. The clinical appearance of hidradenoma papilliferum (HP) is nonspecific, but the location and patient gender are very characteristic. HP is a rare, benign cutaneous adnexal tumor that occurs almost exclusively in the anogenital region of women.
