Blue nevus of the colorectal mucosa

Annals of Diagnostic Pathology, 2011
The blue nevus is a well-described benign melanocytic proliferation that generally occurs on the skin. Infrequently, blue nevi are found on mucosal surfaces. The most common location for mucosal blue nevi is the oral mucosa, with reported cases in the sinonasal mucosa and genital tract, as well as in other locations.

Amelanotic Blue Nevus: A Variant of Blue Nevus

The American Journal of Dermatopathology, 1999
Blue nevi are typically heavily melanized. We report a variant of blue nevus that is minimally pigmented. Of the 1,358 blue nevi seen in our laboratory during the last 6 years, 38 (2.7%) were selected that had scant or absent melanin. We refer to these blue nevi as the amelanotic type. Approximately half of the cases in clinical diagnosis were nevus of

Blue nevus and “malignant blue nevus:” A concise review

Seminars in Diagnostic Pathology, 2016
Blue nevi are a heterogeneous group of lesions that can display a variety of different clinicopathological characteristics. Although attempts are made to classify each lesion into defined subtypes, there can be overlap between the subtypes. The clinical and histolopathologic features of common blue nevi and cellular blue nevi are discussed, as well as ...

Blue Nevus(“Common” blue nevus)

2004
The “common” blue nevus, is a benign neoplasm composed of dendritic melanocytes accompanied by numerous melanophages. The lesion is entirely contained in the dermis, without a junctional component. The common blue nevus constitutes a clinical and morphological continuum with the so called “cellular” blue nevus, discussed in the next chapter.

Blue Nevus (“cellular” blue nevus)

2004
The so called cellular blue nevus is a form of blue nevus which is composed of ovoid, pale, scarcely pigmented, non dendritic cells, while usually having at least a few dendritic, heavily pigmented melanocytes of the “common” form. These pale ovoid cells have a distinct inclination to aggregate in tightly packed round to oval nests. The term “cellular”
