Two Cases of Supernumerary Nipple

PURPOSE: Supernumerary nipple or polythelia is one of the developmental anomalies occurring at the embryonic stage and this anomaly usually arises from the milk line. While this atypical feature is determined during early developmental stage, it may not come out obviously or become troublesome until puberty or lactation. Moreover, sometimes it is confused with a pigmented nevus. METHODS: Case 1, a 18-year-old woman with intramammary supernumerary breast consisted of another nipple with middle sized areola on the right lower breast was admitted for a 2.8 x 3.1 cm-sized mass on the right breast which was starting appeared 1 year earlier. The preliminary cytological examination of the material obtained by needle aspiration biopsy from the mass was revealed by fibroadenoma with no malignant change. The patient had the surgical excision of the mass and accessory breast. Case 2, a 16 year-old woman admitted for intra-areolar polythelia of the left breast, even she doesn't have any family history of polythelia. Since she wanted surgical correction of her atypical nipple for aesthetic and psychological reasons, we reconstructed the areola using transposition flaps in an S-plasty design. RESULTS: Case 1, the excised supernumerary nipple showed following histological features. In the superficial layer, an acanthotic and hyperpigmented epithelium with elongated rete ridges was found. In the dermis, there were follicles with hairs surrounded by hypertrophic sebaceous glands. In the deepest portion, abundant secretory glomerules and excretory ducts of apocrine gland type were observed. Case 2, follow-up visits 3 months after the procedure showed a satisfactory result with good shape and projection of the nipple. CONCLUSION: We report two cases of aberrant mammary tissue who underwent surgical correction, including complete breast (with nipple, areola, and glandular tissue) and intra-areolar polythelia according to the Kajava's classification, and the results were satisfactory.

Supernumerary Nipple Associated with Unilateral Renal Agenesis / 대한피부과학회지

Supernumerary nipple is a developmental anomaly that occurs along the course of the embryological milk lines. The prevalence appears to be higher in women and a wide range of congenital and hereditary anomalies have been described in association with supernumerary nipple, including cardiovascular, gastrointestinal, skeletal and neurologic anomalies, and especially renal and urinary tract anomalies. However, there has been no report of supernumerary nipple with renal anomalies in the Korean dermatologic literature. Herein, we report on an interesting case of a supernumerary nipple with unilateral renal agenesis in a 15-year old man.

A Case of Supernumerary Nipple / 대한피부과학회지

Supernumerary nipple is a rare developmental anomaly occuring along the course of the embryological mammary lines, usually over the anterior aspect of the chest, axilla, and abdominal wall. We, herein, report a case of supernumerary nipple of the most common type in a 30-year-old woman, which has accessory nipples without aberrant gland tissue.

A case of multiple lentigines syndrome / 대한피부과학회지

Supernunmerary nipple is a developmental anomaly occuring alon, the course of the embryological milk lines. This entity has receieved little attention in the dermatologic literature and has been confused with a pigmented nevus in some cases. We have experienced two ease of the more unusual form of supern umerary nipple. According to the Kajavas classification, our caes are classified as polithelia pilosa and complete breast with nipple
