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.

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.

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”

Journal of the American Podiatric Medical Association, 1995
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.

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 ...

Archives of Dermatology, 1956
Junction activity is one of the well-recognized histologic features of primary malignant melanomas of skin and mucous membrane. Its absence in a pigmented tumor revealing cellular and nuclear pleomorphism, mitoses, and invasion is usually indicative of the metastatic nature of the neoplasm or represents a local recurrence.

Blue nevus of the colorectal mucosa
Annals of Diagnostic Pathology, 2011The 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.

Blue nevus of the uterine cervix
Cancer, 1967This paper describes 3 instances of melanotic nevi occurring in the stroma of the uterine cervix, a subject heretofore discussed primarily in the foreign literature. The lesion is interpreted as a visceral analogue of the cutaneous blue nevus. The presence of stromal blue nevi in the cervix and the prostate support a neural origin for the cell of the ...

Journal of Cutaneous Pathology, 1980
Cellular blue nevus can be clinically and histogenetically confused with malignant melanoma but remains a benign neoplasm of uncertain histogenesis. This paper reports the ultrastructural features of three cases of cellular blue nevus and emphasizes melanosomal alterations, including immature and granular forms, multiple layers of basement membrane ...

Malignant blue nevus of the scalp
International Journal of Dermatology, 1998A 70‐year‐old woman had noticed, at the age of 30, a single blue nodule of about 1 cm in size on her scalp. The lesion remained stable until 1991, when it became larger and ulcerated and, because of the sudden onset of additional macules and nodules around it, the patient presented at our Dermatological Division in August 1992.Physical examination ...
