AI Article Synopsis

  • Anogenital mammary-like glands can develop various pathological lesions similar to those found in breast pathology, although tumors in this region are quite rare.
  • A case study of a 28-year-old woman with a painless mass led to the discovery of a benign phyllodes tumor during microscopic examination.
  • The report highlights the need to recognize these uncommon lesions in unusual locations, discussing their potential origins and reviewing existing literature on similar cases.

Article Abstract

Anogenital mammary-like glands may give rise to various pathologic lesions identical to those known in mammary pathology. Tumor occurring in the anogenital region is extremely rare. The histogenetic origin of this tumor is controversial as it is being debated whether such lesions evolve from ectopic breast tissue and most recently, anogenital mammary-like gland. We report a 28-year-old girl who presented with a painless mass in the anogenital region, which was subsequently excised. Microscopic examination revealed morphologic pattern characteristic of benign phyllodes tumor with pseudoangiomatous stromal hyperplasia. We present this case to emphasize the importance of recognizing this uncommon lesion occurring at an extremely unusual site. We also discuss the histogenesis of phyllodes tumor and related lesions occurring in the anogenital region in light of the current literature along with a brief review of the previously reported cases of anogenital mammary-like glands.

Anogenital mammary-like glands (AGMLGs) are present in the anogenital region that bear striking morphologic and protein-expression similarities to mammary glands in the breast. AGMLGs can give rise to both benign and malignant lesions which mimic primary breast lesions. Herein, we report two mammary-type adenocarcinomas arising from AGMLGs, including one in the previously unreported site of the rectum.

Vulvar Lactating Adenoma: A Rare Representation of Mammary-Like Anogenital Glands.

Int J Surg Pathol

December 2024

Department of Pathology, Molecular and Cell-Based Medicine, Icahn School of Medicine at Mount Sinai, New York City, NY, USA.

Mammary-like anogenital glands are considered a normal constituent of the anogenital area. These glands can have epithelial components with eccrine or apocrine features. They often undergo transformation into mammary-like lesions, including lactational changes that occur during pregnancy and the breastfeeding period.

Article Synopsis
  • * A 73-year-old woman exhibited a non-painful, slowly growing vulvar mass, which upon surgical excision, revealed a nodular mass with mucinous characteristics and a specific tumor profile.
  • * The findings suggest that this type of vulvar carcinoma shares similarities with breast encapsulated papillary carcinoma, leading to a tailored treatment approach focusing on its localized and slow-progressing nature, differing from other more aggressive vulvar adenocarcinomas.

A Rare Case of Hidradenoma Papilliferum of the Vulva.

J Obstet Gynaecol India

June 2024

Apollo Hospital, Navi Mumbai, India.

Article Synopsis
  • - Hidradenoma Papilliferum is a rare but benign tumor found predominantly in the anogenital region of women aged 30-49, although it can also appear in atypical locations like the breast, ears, and eyelids, known as Ectopic Hidradenoma Papilliferum.
  • - The tumor arises from apocrine or mammary-like glands and is characterized by a firm nodule with no connection to the skin's surface, often described as having a flesh to red color and a frond-like structure upon examination.
  • - A case study highlights a 33-year-old woman who experienced a slow-growing nodule in her perineum for eight months; a biopsy confirmed the diagnosis

TRPS1 Is Consistently Expressed in Hidradenoma Papilliferum.

Int J Gynecol Pathol

June 2024

Department of Pathology, Ghent University Hospital; Cancer Research Institute Ghent (CRIG), Ghent University.

TRPS1 is a novel immunohistochemical marker, so far quite specific and sensitive for breast cancer and especially useful for the diagnosis of triple-negative breast cancer. TRPS1 expression has recently been reported in normal skin appendages, as well as in a variety of benign and malignant cutaneous tumors, including adnexal tumors. However, it has not yet been reported in hidradenoma papilliferum (papillary hidradenoma), a benign adnexal neoplasm, accepted to originate from mammary-like glands in the vulvar or anogenital region of middle-aged women.
