The “nevus of Ota” is a hypermelanotic melanocytic phacomatosis, characterised by: (1) a (usually unilateral) area of non-hairy, macular or slightly raised hamartomatous hyperpigmentation (usually blue or grey in colour) involving the skin and mucous membranes at the forehead, temple, or eyelids over the distribution of the 1st and 2nd division of the ...

A 23-year-old man presented with a 2-year history of a slow growing lesion in the left eye. The lesion consisted of a vascularized, balloon-like mass straddling the limbus nasally (A). Histopathologic examination demonstrates (B) a conjunctival epitheliumwith solar elastosis, consistent with a pterygium (left side), and proliferation of melanocytic ...

A man had a long history of a persistent, fixed area of livid erythema on the trunk. The distribution of hair, sweat, and sensation were normal as were the histologic findings in the affected skin. The involved area had a decreased total skin blood flow and a lower surface temperature compared with surrounding uninvolved skin, but showed normal ...

Nevus of Ota and nevus of Ito are uncommon sporadic forms of dermal melanocytosis. They may be associated with capillary malformations. In rare cases malignant melanoma may develop in the skin or the uvea. GNAQ mutations have been detected in some. Some degree of lightening can be achieved with lasers.

Desmoplastic Nevus: An entity Distinct From Spitz Nevus and Blue Nevus
The American Journal of Dermatopathology, 2011Desmoplastic (sclerotic) nevus is an infrequently reported poorly characterized benign melanocytic proliferation, with only 4 case series published to date. To better define this nevus, we examined the clinical and histologic features of 25 lesions.

Dysplastic nevi are distinctive cutaneous nevomelanocytic lesions that can be recognized clinically and histologically. They were first described as markers of risk for melanoma in members of hereditary melanoma-prone kindreds. Subsequently, they have been discovered in a significant fraction of patients with sporadic melanoma, and in apparently normal

To provide an up-to-date review of the epidemiology, presentation, diagnosis, and treatment options for conjunctival nevi (CN).Around 17.2%-42% of all conjunctival tumors have been found to be CN, which most frequently present in White individuals between the first to early third decade of life, with equal distribution between males and females.

Histologically, the so-called halo nevus is overwhelmed by an infl ammatory, mostly lymphocytic infi ltrate with extensive loss of melanocytes. The clinically evident white halo corresponds to the loss of melanin in the basal layer of the epidermis and to a reduction in the number of melanocytes.

Dysplastic nevi have become an increasing focus clinically, with evidence that they are associated with a higher risk of developing melanoma. However, there still is contention regarding the significance of dysplastic nevi. This contribution provides an overview of the history, epidemiology, genetics, clinical and histologic features, and procedures ...
