A Rare Case of Hidradenoma Papilliferum of the Vulva.

Hidradenoma Papilliferum is an uncommon benign neoplasm typically presents in the anogenital region of 30 to 49 years old females. Rarely it can be seen over the head and over modified apocrine glands area such as breast, external ear canal and eyelids. In these cases, it is referred to as Ectopic Hidradenoma Papilliferum. It usually arises from mammary like glands or apocrine glands, in middle aged females. It has histopathological similarities to intraductul papilloma of breast. Clinically It presents as an isolated dermal or subcutaneous nodule which is said to have no connection to the epidermis. Interestingly the lack of communication with the overlying epithelium is accepted by some as criteria for diagnosis. It usually presents as a firm, flesh to red- coloured nodule in the anogenital area. The nodule is composed of tubules and papillary structures arranged in a frond like pattern. Here I present a case report of 33 Years old unmarried, sexually active female, presented with complaint of, a small swelling over perineum for last 8 months. The swelling has been growing very slowly without any other associated complaints. A biopsy was taken on an outpatient basis which confirmed the diagnosis and patient was treated with complete excision of the lesion.
