The cells of retinoblastoma, melanoma and dysplastic nevus are derived from the neural crest. There are authors who postulate that patients with retinoblastoma and dysplastic nevus syndrome have increased genetic susceptibility to melanoma due to a primary anomaly...
متن کاملParallel ridge pattern on dermoscopy: observation in non-melanoma cases*
The acral melanoma is the most prevalent type of melanoma in the non-Caucasian population, and dermoscopy is a useful tool for earlier diagnosis and differentiation from benign lesions. The dermoscopic pattern often associated with melanoma on the volar skin is the parallel ridge, with 99% specificity according to the literature. However, this pattern can also occur in several benign acral lesi...
متن کاملAtypical dermoscopic presentation of an acral congenital melanocytic nevus in an adult: parallel ridge pattern and its histologic correlation
Acral melanoma is the most frequent subtype in the Asian and Mexican mestizo populations. Dermoscopy is a noninvasive diagnostic technique that helps the differential diagnosis of pigmented skin lesions on acral volar skin. We, herein, present a case of acral congenital melanocytic nevus with a parallel ridge dermoscopic pattern. Since the parallel ridge pattern in a melanocytic lesion of the a...
متن کاملKey points in dermoscopic differentiation between early acral melanoma and acral nevus.
Acral skin is the most prevalent site of malignant melanoma in non-Caucasian populations. On acral skin, other various kinds of pigmented lesions are also detected. Particularly, melanocytic nevus is commonly seen on acral volar skin; approximately 10% of Japanese have a nevus on their soles. Prognosis of acral melanoma is still generally poor because of delayed detection in the advanced stages...
