Tubular Apocrine Adenoma – Case Report and Systematic Review

Abstract

Tubular apocrine adenomas (TAA) are rare, benign, slow growing, Skin adnexal tumors with limited reported cases in literature. Tubular apocrine adenomas resemble papillary eccrine adenomas, and these two tumors were once regarded as identical.[17] Here we present a case of tubular apocrine adenoma in a 47 years old female.

Tubular Apocrine Adenoma – A Case Report of Rare Sweat Gland Tumor

“…[5] Over half of them occur above the level of the shoulders. [2] In our case, the site of tumor was right temporal region, which was in consistence with fact that majority of the reported tubular apocrine adenomas occurred above the level of the shoulder . This body distribution is surprising since apocrine glands are found usually in the axilla and anogenital regions and have very limited distribution in the body otherwise.…”

“…TAA is predominantly found in women with a M:F ratio of 1:2. [2,3] The wide age distribution ranges between 6 days [15] and 78 years. [6] The finding of a tubular apocrine adenoma in a female of middle age in our case is in concordance with what others have reported.…”

“…[6] The finding of a tubular apocrine adenoma in a female of middle age in our case is in concordance with what others have reported. [1][2][3][4][5][6][7]10,12,[14][15][16][17][18] Tubular apocrine adenoma is found most commonly on the scalp but lesions have also been described at a variety of other sites including the face, [6] eyelid, [18] axilla, [3] leg and genitalia. [4,11,17] However, Lee et al reported a case in the external auditory canal.…”

“…[1] Tubular apocrine adenoma is frequently found associated with other dermal neoplasms like nevus sebaceous/organoid naevus of Jadassohn (NS) and syringocystadenoma papilliferum (SCAP). [2] Tubular apocrine adenoma is a well circumscribed, nodular, slow growing, intra dermal benign tumor with tubular structures showing apocrine differentiation. Clinically, the tumor generally presents as a dermal nodule 1-2 cms in diameter or pedunculated lesion, frequently of many years duration.…”
