Tubular apocrine adenoma with syringocystadenoma papilliferum arising from the external auditory canal.
ABSTRACT Tubular apocrine adenoma (TAA) is a very rare sweat gland tumour. Comprehensive review of the literature reveals that TAA in the external auditory canal (EAC) has not yet been reported. We report a case of TAA in the EAC, together with characteristic histopathological findings.

ABSTRACT: Syringocystadenoma papilliferum (SCAP) occurs singly or in association with other tumors. Although it is rare, the association of tubular apocrine adenoma (TAA) with SCAP in the background of nevus sebaceous (NS) on the scalp is well documented. However, the co-existence of these two tumors without background of NS has not been reported on the extremities. We report a case of SCAP associated with TAA on the calf without pre-existing NS in an adult. (Ann Dermatol 23(S2) S175 similar to S178, 2011)Annals of Dermatology 10/2011; 23(Suppl 2):S175-8.

ABSTRACT: Syringocystadenoma papilliferum (SCAP) is an uncommon benign adnexal tumor of the skin. It is frequently seen in association with other benign adnexal lesions, such as nevus sebaceous, apocrine nevus, tubular apocrine adenoma, apocrine hidrocystoma, apocrine cystadenoma, and clear cell syringoma. The unusual reported locations of SCAP include the head and neck, the buttock, the vulva, the scrotum, the pinna, the eyelid, the outer ear canal, the forehead, the back, the scalp, the thigh, the nipple, the axilla, and the postoperative scar. The occurrence of SCAP in the right lower abdomen is distinctly uncommon. Herein, we report an unusual case of a 41-year-old man with SCAP occurring in the right lower abdomen that did not develop malignancy, despite a long disease course and an absence of medical treatment. The clinical and histopathologic features and the differential diagnosis of SCAP are also discussed.OncoTargets and Therapy 03/2013; 6:233-6. DOI:10.2147/OTT.S42732 · 1.34 Impact Factor
