Hidradenoma
papilliferum is a rare, benign, cystic, papillary apocrine gland tumor
that occurs almost exclusively in women in the skin of the anogenital
region. We present the case of a 66 year old woman who presented with
a progressively enlarging perianal nodule. We provide a review of the
literature emphasizing the clinico-pathological characteristics and
differential diagnosis. Local excision is necessary for identification
and cure. No recurrence was observed after one year follow-up.
Non-anogenital (ectopic) hidradenoma papilliferum with sebaceous
differentiation: a case report and review of reported cases.
J Dermatol. 2006 Apr;33(4): 256-9.
Hidradenoma
papilliferum is a benign tumor that usually occurs in the female
anogenital region. We present a 52-year-old male with a non-anogenital
(ectopic) hidradenoma papilliferum on his face. He had had a
subcutaneous tumor on his right eyebrow for 30 years. The histological
findings included variously shaped cystic and tubular structures in
the tumor. The lumina were surrounded by a double layer of cells and
showed active decapitation secretion. The lesion contained sebaceous
differentiation, which has not been previously documented in the
histopathology of hidradenoma papilliferum. We review the published
work of non-anogenital (ectopic) hidradenoma papilliferum tumors on
the head and neck. |
