A Rare Case of Accessory Breast Mimicking Lipoma in a Male

Abstract

Accessory breast tissue is a rare condition in which there is a presence of breast tissue in an ectopic site in addition to normal site. It occurs in about 0.4-6% of women and 1.68% occurrence is seen in men. The obstacle to management comes in the diagnosis of the accessory breast tissue. The commonest site is the axilla, and the other sites of occurrence are groin, buttock and thigh. The disease may present as a unilateral swelling with changes occurring during the time of pregnancy, lactation and menses due to the influence of hormones. This breast tissue also undergoes the changes that occur in a normal breast tissue such as fibrocystic changes or carcinomatous changes. A case of accessory breast tissue was reported in a 28-year-old-male which was initially suspected to be a pedunculated lipoma in the right axillary region and later on histopathological evaluation diagnosed to be an accessory breast tissue.
