We report a case of a 37-year-old male with a conjunctival melanocytic nevus presenting in a rare, peripunctal location with preservation of the lacrimal canaliculus and punctum.

ABSTRACTCongenital melanocytic naevi, consisting of clusters of naevo‐melanocytes, develop in utero. Although many congenital naevi are visible at birth, some may not become evident until later in life. The timing of naevo‐melanocyte proliferation, senescence and melanogenesis may all contribute towards determining when a naevus will become clinically ...

Abstract:Thirty‐five percent of 363 melanocytic nevi were found to have a keratotic epithelial architectural pattern that was mostly infundibular and not previously emphasized. Keratotic melanocytic nevi were commonly from the trunk of women, and most were associated with an intradermal melanocytic nevus.

Ultrastructural Pathology, 1994
Electron microscopic examination was performed of skin biopsy specimens processed for electron microscopy directly after formaldehyde fixation, after retrieval from paraffin blocks, and as for paraffin embedding but with retrieval after clearing with xylene, the last step before paraffin infiltration.

Melanomas are among the most common skin tumors in horses, with prevalence rates reaching as high as 80% in adult gray horses. Most melanocytic tumors are benign at initial presentation; however, if left untreated, up to two-thirds can progress to overt malignant behavior.

Congenital nevi are characterized by the appearance of pigmented areas that range in size, shape, surface texture, and hairiness. In most cases, the nevus remains stable and benign, but because of possible malignant transformation, nevi are often excised.

Clinics in Plastic Surgery
Congenital melanocytic nevi are benign neoplasms, which present early in life at various anatomic locations with a variety of clinical presentations. When evaluating large or giant nevi, it's important to use a multidisciplinary team and rule out comorbid conditions, such as neurocutaneous melanosis.

Malignant Melanocytic Trichoblastoma
Annals of Plastic Surgery, 2006Trichoblastoma is an uncommon benign cutaneous neoplasm of the hair germ cell. The pigmented variety of the tumor is rare. There have only been a few case reports describing the malignant counterpart of trichoblastoma. There are no reports describing a pigmented variety of malignant trichoblastoma.

Melanocytic Conjunctival Tumors
Ophthalmology Clinics of North America, 2005Melanocytic conjunctival tumors include a wide range of lesions that vary in their clinical and histopathologic features. Their management depends on numerous factors, including their location, focality, tumor dimensions (including depth), histopathologic characteristics, recurrences, growth, and the presence of metastasis.

Different types of melanocytic nevi do exist in relation to their epidemiology, evolution, morphology, genetics, and their associated melanoma risk. The introduction of dermoscopy has opened a new morphologic dimension of melanocytic nevi; this along with recent progresses in our understanding of the molecular pathways involved in the formation of nevi
