acrospiroma/progesterone

We present the case of a 33-year-old female who developed a cystic nodule on the vulva during pregnancy. Immediately following Cesarean section, the lesion was biopsied and histologic examination revealed a dermal tumor composed of glandular structures arranged in a labyrinth pattern. The glandular

OBJECTIVE To make a quantitative evaluation by image analysis of oestrogen receptors, progesterone receptors, and androgen receptors in papillary hidradenomas and anogenital sweat glands. METHODS 20 papillary hidradenomas and the anogenital sweat glands detected in surgical specimens selected from

We report a case of a 26-year-old woman with an 8.0-cm tumor of the left breast. The tumor was clinically and radiologically suspicious for malignancy. The pathologic evaluation of the core biopsy and the subsequent excision specimen revealed a benign sclerosing, cystic, and papillary adnexal tumor

A new case of breast tumor with features of eccrine spiradenoma is described. This neoplasm is exceedingly rare, because only two cases, arising in breast parenchima, have been previously reported. The patient was a 43-year-old woman and she experienced three local recurrences at 7, 20, and 30

A 58-year-old female had a mass in the right breast palpable beneath the areola. A mammogram revealed a 1.5-centimeter soft tissue density that was confirmed with a subsequent ultrasound. The patient underwent a core needle biopsy which was initially reported as a moderately differentiated invasive

Adenocarcinoma in situ rarely occurs in vulvar papillary hidradenoma. We encountered 2 cases of adenocarcinoma in situ arising in a papillary hidradenoma of the vulva. Both patients were asymptomatic women, aged 83 and 92 years, who presented with nodules (1.0 and 2.0 cm) on the vulva.

BACKGROUND Fine-needle aspiration (FNA) is well-established as an accurate technique for the diagnosis of palpable breast masses. While the differential diagnosis of such lesions usually focuses on benign or malignant mammary proliferations, a subset of breast neoplasms arises from skin and soft

Hidradenocarcinomas are rare, aggressive adnexal tumors of sweat gland origin that demonstrate a high potential for local recurrence, metastasis and poor outcome. These neoplasms can derive from preexisting clear cell hidradenomas, but more commonly appear de novo with the molecular events

We report and immunohistochemically document the first (to the best of our knowledge) case of malignancy in which an intraductal carcinoma resembling apocrine breast cancer arose within a papillary hidradenoma of the vulva. Papillary hidradenoma is generally thought to originate from apocrine sweat

Extramammary fibroadenomas, occurring in the anogenital region, are rare lesions thought to be arising from "mammary-like anogenital sweet glands" described by van der Putte. We present a 42-year-old woman with a slow-growing, 4-cm, well-circumscribed but nonencapsulated mass in perianal region. The
