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 ...

Journal of the American Academy of Dermatology, 2003
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.

Solitary Intratarsal Blue Nevus
Ophthalmic Plastic & Reconstructive Surgery, 2022A 42-year-old woman presented with a small pigmented lesion of the palpebral conjunctiva that had been present for a few months. Because of the possibility of melanoma, the lesion was resected. Microscopic examination displayed an intratarsal blue nevus at the level of the meibomian glands comprised of bland nonpigmented and pigmented cells that ...

BAP-1 Expression Status by Immunohistochemistry in Cellular Blue Nevus and Blue Nevus-like Melanoma.
American journal of dermatopathology, 2020The family of blue nevi includes the common blue nevus (BN), cellular blue nevus (CBN), and atypical BN, while melanomas with BN-like morphology can either arise in association with a blue nevus (MABN) or in the de novo setting mimicking cellular blue ...

Atypical Cellular Blue Nevus With Necrosis Mimicking Melanoma Ex-Blue Nevus
The American Journal of Dermatopathology, 2021Abstract: Histologic distinction between melanoma ex-blue nevus and cellular blue nevus (CBN) can often be difficult, but features supporting melanoma include infiltrative growth pattern, frequent mitoses, cytologic atypia and pleomorphism, cell crowding, and tumor necrosis.

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 ...
