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.

Hypopigmented common blue nevus
Journal of Cutaneous Pathology, 1997Blue nevus is a benign pigmented lesion of dermal melanocytes with a number of histologic and clinical variants, of which the major types are the common blue nevus, cellular blue nevus and combined nevus.This study describes 9 cases of hypopigmented blue nevus (HBN), a variant of common blue nevus in which there is minimal identifiable melanin pigment.

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.

Because of the appearance and consistency of the lesions, Bean 2 has given the name blue rubber bleb nevus to a variant of hemangioma probably first described by Gascoyen. 6 Although a century has elapsed since the original article appeared, the disorder is still not well recognized.

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 ...

In a 6-year-old boy, we found a malignant blue nevus with metastases of the lymph nodes. After surgical therapy under melanoma conditions, he was treated with interferon. Up to now (2 years after therapy), the follow-up examinations have been negative.

In two cases of target blue nevi of the foot, both lesions displayed a distinctive concentric pigmentary variation. This correlated histologically with a peripheral alteration of dermal collagen accompanied by a focal regression or differentiation of blue nevus cells.

[Malignant blue nevus in Ota's nevus].
Der Hautarzt; Zeitschrift fur Dermatologie, Venerologie, und verwandte Gebiete, 1984A 21-year-old Caucasian woman with congenital nevus of Ota developed a subcutaneous tumor below the lacrimal sack within the area of discoloration. The tumor, located subcutaneously, has been present for 4 years. Histologically, parts of the tumor showed neuroid structures as well as those like cellular blue nevus.
