Cleft-like appearance of accessory nipple in digital microscopy*

Dear Sir, Accessory nipples are solitary or multiple rudimentary nipples developing along the two vertical ‘milk-lines’. Most cases are sporadic and asymptomatic. Accessory nipple occurs in 1-6% of the population and affects both genders equally.1 It is often mistaken as dermatofi broma in clinical or dermatoscopic examination. Blum et al. have reported a case of accessory nipple indistinguishable from dermatofi broma, with dermatoscopic features such as peripheral pigment network and central scar-like white-colored area.2 Oztas and Gurer detected a cleft-like appearance in the dermatoscopic evaluation of four of their fi ve patients.3 Herein, we would like to point out the potential of portable digital microscopy for the diagnosis of accessory nipple in clinical practice. In our clinic, we use a Celestron handheld digital Microscope model #44301, at 30-fold magnifi cation, provided with a focus ring and six LED ring illuminators. It has a resolution of 1280 x 1024 pixels and provides JPEG-format digital images, which are downloaded via USB connection to a personal computer.
