INTRODUCTION A congenital lower lip nevus is common, but a lower lip length lesion of more than 40% is hard to excise simply, without any distortion. We designed a lower lip bilateral advanced skin flap to restore the wound surface after completely and successfully removing the nevus. CASE PRESENTATION A 13-year-old Mongolian girl was referred to us with a giant congenital lower lip nevus. Th...

Divided nevus or kissing nevus is a rare form of congenital nevus that usually occurs on adjacent parts of the upper and lower eyelids of one eye. Most often, the formation is present from birth, but it may also appear later. Three new cases during the period 1996 to 2004 are reported. Two of them were treated in our unit for oncological, functional and aesthetic purposes, and one preferred not...

C-Kit (CD117), the receptor for the stem cell factor, a growth factor for melanocyte migration and proliferation, has shown differential immunostaining in various benign and malignant melanocytic lesions. The purpose of this study is to compare c-Kit immunostaining in benign nevi and in primary and metastatic malignant melanomas, to determine whether c-Kit can aid in the differential diagnosis ...

BACKGROUND The differential diagnosis of common pigmented skin lesions is important in cosmetic dermatology. The computer aided image analysis would be a potent ancillary diagnostic tool when patients are hesitant to undergo a skin biopsy. OBJECTIVE We investigated the numerical parameters discriminating each pigmented skin lesion from another with statistical significance. METHODS For each...

The presence of a high nevus number is the strongest phenotypic predictor of melanoma risk. Here, we describe the results of a three-stage study directed at identifying risk variants for the high nevus phenotype. At the first stage, 263 melanoma cases from Barcelona were genotyped for 223 single-nucleotide polymorphisms (SNPs) in 39 candidate genes. Seven SNPs in the PAX3 gene were found to be ...

Several skin conditions have been reported to occur on epidermal nevi, but it seems that co-occurrence of a vascular lesion and an epidermal nevus is a very rare phenomenon. Herein, a 17- year- old female patient who had presented with skin lesions on her thigh since 4 years ago has been reported. The lesions were two oval plaques consisted of multiple brown- tinted, hyperkereratotic papu...

Nevus sebaceus is a hamartoma of the sebaceous gland that occurs congenitally, from which various secondary tumors can arise with a prevalence of 5%-6%. Benign neoplasms commonly arise from nevus sebaceous, but they have a very low malignant potential. Two neoplasms may occasionally arise within the same lesion, but it is rare for three or more neoplasms to occur in a nevus sebaceus simultaneou...

PURPOSE To report the clinical and histologic features of combined nevi of the conjunctiva, a type of nevus that is not uncommon in the skin but has rarely been reported in the conjunctiva. METHODS Conjunctival nevi and melanomas from the files of the University of California, San Francisco, eye pathology laboratory were reviewed from 1984 to 1999 for the presence of features of both standard...
