A rare case of fibroadenoma in ectopic breast tissue of axilla: case report

Abstract

Developmental abnormalities of breast can lead to formation of ectopic breast tissue which may present as polymastia or polythelia or in form of swelling along the milk line. Ectopic breast tissue can also develop pathological changes similar to normal located breast tissue. This report is about a case of fibroadenoma developing in ectopic breast tissue of axilla. A thirty-four-year-old female presented with painful swelling in right axilla for 2 years and was diagnosed with fibroadenoma of axillary tail of right breast. Excision biopsy of the swelling confirmed the diagnosis of fibroadenoma. Fibroadenoma must be considered for any axillary swelling along with other differential diagnoses like lymphadenopathy, carcinoma arising from ectopic breast tissue, lipoma, sebaceous cyst, tuberculosis, vascular lesions, cutaneous malignancies or secondaries in lymph nodes. Ectopic breast tissue should be subjected to similar evaluation and screening as is recommended for normally located breast tissue. The patient should also be evaluated for possibility of kidney and urinary tract malformations.

Intra-abdominal ectopic breast tissue in male patient presenting as a fibroadenoma: a case report

“…The delay is due to a broad differential diagnosis, including lipoma, vascular neoplasm, suppurative hidradenitis, lymphadenopathy, sebaceous cysts, tuberculosis, and malignancy. Some kidney and urinary tract malformations found to be associated with EBT include adult dominant polycystic kidney disease, cystic renal dysplasia, unilateral renal agenesis, familial renal cysts, and congenital stenosis of the pyeloureteral joint 15 . A suspicious lesion found anywhere in the abdomen and thoracic cavity; FA should also be included in the differential diagnosis.…”

Giant Lipoma of the Arm Masquerading as an Accessory Breast: A Report of a Rare Case

“…A different method of tumescent liposuction was discovered that enables patients to avoid the central depression appearance that is frequently left behind after the usual ways of resecting the accessory breast tissue [ 14 ]. With this alternate treatment, less scarring and a better shape may be achieved than with traditional techniques [ 15 ].…”

Unusual intracystic papilloma arising from ectopic axillary breast tissue: Case report

“…This condition is also known as supernumerary breast, ectopic breast, and polymastia, and it frequently develops along the “milk line” or mammary line [2] , [3] , [4] . Gender, geographical area, race, and inheritance have all been proven to influence the incidence of accessory breast tissue.…”
