Dermoscopy of accessory nipples in authors’ own study

Abstract

IntroductionThe accessory nipple (AN) is characterised by its network-like structures, which may suggest the diagnosis of a melanocytic lesion. The knowledge about additional dermoscopic features of AN may greatly minimise the risk of unnecessary surgical excisions.AimTo analyse and present different clinical and dermoscopic forms, in which the AN may appear.Material and methodsNinety AN with dermoscopic features were evaluated in the study, detected in 14 patients between the years 2008 and 2014.ResultsThe most common dermoscopic features of the AN were central, scar-like areas (15/19) and peripheral network-like structures (12/19). A number of cleft-like appearances (8/19) and central network-like structures (7/19) had also been observed. Moreover, among the dermoscopic features, white cobblestone-like structures (7/19), a central round dimpling with a plug (6/19) and fisheye-like structures resembling comedo-like openings (9/19) have all also been noted. There is a statistical significance in the occurrence of white cobblestone-like structures with central network-like structures (Fisher's exact test p = 0.0449). The presence of peripheral network-like structures with the occurrence of central scar-like areas was statistically highly significant (p = 0.0091). The central round dimpling was never observed alongside any central network-like structures in any of the lesions (p = 0.0436).ConclusionsAccessory nipples are most commonly characterised by the occurrence of a peripheral network-like structure accompanied by the presence of a scar-like area.

Nevi and Other Developmental Defects

“…Developmental Defect of the Body 2.9.1 Accessory Nipple and Accessory Breast • Definition: An accessory nipple or breast is an additional area of breast with areola formation that may occur anywhere along the milk line. In particular, the accessory breast is often seen in an axillary area, but accessory nipples are more usual for the lateral chest under the breast (Kamińska-Winciorek et al 2014).…”

Cutaneous Disorders of the Breast

“…1 and 2). Dermatoscopy of accessory nipple is characteristic with peripheral pigment network and a central scar-like patch (Geffroy and Doutriaux-Dumoulins 2015;Kamińska-Winciorek et al 2014a;Oztas and Gurer 2007). • Pathological manifestation: Its histologic features are identical to that of the regular nipple, including hyperpigmentation, slight hyperkeratosis with epidermal thickening, pilosebaceous structure of Montgomery areolar tubercles, smooth muscle bundles typical of the areola, and possible mammary glands and intradermal straight ducts (Stone and Wheeler 2015;Jansen 2014).…”
