background spitz nevus is an infrequent acquired melanocytic nevus. there is still a challenge for dermatopathologists in distinguishing spitz nevus from malignant melanoma particularly in adults since there is no immunohistochemistry or molecular markers which differentiate spitz nevus from melanoma. objectives the aim of this study is to make clear what clinico-histopathological features of s...

Becker's nevus, also called Becker's melanosis or pigmented hairy epidermal nevus, is a benign cutaneous hamartoma characterized by hyperpigmented macule usually with hypertrichosis. It is rarely associated with neurofibromatosis. We report a 2 1⁄2 yrs old male child with coexistent congenital Becker’s nevus and type 1 neurofibromatosis.

Nevus is a group of melanocytes that grow together to form benign growth on the skin. It often black lesion may protrude from Becker's nevus hyperpigmented presents congenitally or acquired. The pigmentation and unusually high hair might darker with time. nevus, which can interchangeably be called melanosis, rare disease usually presented by men. following case 21-year-old male who his right ar...

Differentiating Spitz nevus from malignant melanoma is difficult and controversial. Despite helpful lists of differential diagnostic features, uncertainty about the diagnosis often provokes some to stain the tumor for MIB-1 antibody to Ki-67 and measure the proliferation index (PI) of the tumor. Of the many reports about MIB-1 PI in Spitz nevi and melanoma, none have consolidated the informatio...

Epidermal nevi are hamartomas that are characterized by hyperplasia of epidermis and adnexal structures. These nevi may be classified into a number of distinct variants, which are based on clinical morphology, extent of involvement, and the predominant epidermal structure in the lesion. Variants include verrucous epidermal nevus, nevus sebaceous, nevus comedonicus, eccrine nevus, apocrine nevus...

BACKGROUND Kissing nevus is a congenital nevus in adjacent parts of the eyelids. Malignant transformation of kissing or divided nevi of the eyelids is rarely described. OBJECTIVE To report a very rare case of malignant transformation of kissing nevus with ocular and extraocular spread. CASE A 57- year- old man with 6/6 visual acuity in both eyes presented with a kissing nevus present since ...

Purpose The aim of this article is to report a case of lacrimal caruncle nevus with papilloma. Methods This is a case report of a 39-year-old female with a progressively enlarging pigmented lesion on the left lacrimal caruncle. She had been aware of a raised whitish wart on the top of this pigmented lesion for several months before her initial visit. Slit lamp examination revealed a papilloma...

Reed nevus or pigmented spindle-cell nevus may mimic cutaneous melanoma; however, its dermoscopic and histopathological characteristics are different. This case report describes three patients with distinct clinical, dermoscopic and histopathological presentations, which were correlated to enable a differential diagnosis to be made between melanoma and Spitz nevus

There are at least two pathways driving cutaneous melanoma; one is linked to an inherent melanoma susceptibility to nevi development and the second to environmental cumulative ultraviolet light exposure. In this study, we examined the relation between nevus density, accrued sun damage and the site of primary melanoma excision. In a series of 888 consecutive cutaneous melanoma patients, melanoma...
