Dermatoscopy of pigmented extramammary Paget disease simulating melanoma

Clinical and dermoscopic characteristics of extramammary Paget disease: a study of 35 cases

“…Early diagnosis and treatment of EMPD are crucial for a favourable prognosis, because a delayed diagnosis can result in a more extensive lesion, dermal invasion or distant metastasis. Although the utility of dermoscopy has been reported for various pigmented and nonpigmented tumours, the dermoscopic patterns of EMPD have rarely been reported in the literature . Investigation of clinical and dermoscopic patterns of EMPD could elucidate further characteristics of this rare tumour.…”

Pigmented extramammary Paget disease of the thigh mimicking a melanocytic tumor: report of a case and review of the literature

“…Pigmented EMPD was first described clinically by Cuberson and Horn and represents an exceedingly rare lesion: only 10 well‐documented cases have been reported so far in the literature, although this low number likely represents underreporting of the lesion. Pigmented EMPD presents as an irregular, diffusely pigmented plaque or macule, which clinically can mimic a melanocytic lesion . Histopathologically, pigmented EMPD resembles other forms of MPD and EMPD, except the intraepidermal tumor cells typically contain varying amounts of finely granular intracytoplasmic melanin pigment, and there are usually melanophages in the subjacent superficial dermis .…”

Erythematous plaques of the vulvo‐perineal region: diagnostic role of dermatoscopy

“…The dermatoscopic features of EMPD have rarely been described. In this regard, pigmented EMPD may mimic melanoma, as has been shown in a case of scrotal EMPD [ 7 ] . Here dermatoscopy revealed a linear arrangement of globules on a white background, forming a white negative pigment network.…”
