ISSN 0001-5555 Hidradenoma papilliferum is a rare benign neoplasm originating from the apocrine sweat glands. It has been reported primarily to affect Caucasian females, typically during the third to fifth decades of life. The lesions are usually solitary, well-demarcated papules or nodules covered with normal skin, and are generally less than 10 mm in diameter (1). This tumour is frequently asymptomatic, though may be associated with a pruritic, burning sensation or pain. Hidradenoma papilliferum usually occurs in a vulval, perineal or perianal location. When these tumours are not located in the anogenital area, they are termed ectopic hidradenoma papilliferum (2). We report here two cases of ectopic hidradenoma papilliferum of the nose.
