Amelanotic Blue Nevus: A Variant of Blue Nevus
The American Journal of Dermatopathology, 1999Blue 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, 2016Blue 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 ...

Junctional or compound melanocytic nevus and melanoma may involve the nail apparatus and are usually discussed in the differential diagnosis of nail pigmentation. Blue nevus has been very rarely reported in this location. We report the second clinicopathologic study of a subungual blue nevus.

The Journal of Dermatologic Surgery and Oncology, 1985
Abstract. A malignant blue nevus of the dorsum of the hand and a review of the literature is reported. Histopathologic examination showed the presence of a blue nevus and a cellular blue nevus, as well as a malignant blue nevus. The cellular blue nevus elements of the lesion showed the characteristic prominent neural‐type fascicles intertwined with ...

A 36-year-old woman with a long history of amenorrhea underwent endometrial curettage. An aggregate of short spindle cells containing a finely granular, dark brown pigment with the histochemical characteristics of melanin was detected in the endometrial stroma.

According to the original description by Tieche [33], to which little can be added, blue nevus is a dermal-based, benign melanocytic lesion histopathologically made up by variable proportions of oval/spindle and bipolar, usually heavily pigmented dendritic cells (G. Ferrara et al., submitted) [37, 40].

Blue Nevus (“cellular” blue nevus)
2004The 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”

Blue Nevus(“Common” blue nevus)
2004The “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.

Dermal melanocytes are generally most numerous in the sacral, dorsal hand, and dorsal foot. There is also a slight rise that often occurs toward the axial line of the trunk. The practitioner needs to be aware and take necessary measures to properly diagnose the blue nevus from other forms of pigmented skin lesion.
