Archives of Dermatology, 1983 • 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. The resulting distinctive target blue nevus can be clinically differentiated from a

Low‐dose sirolimus for a patient with blue rubber bleb nevus syndrome
Pediatrics International, 2019Blue rubber bleb nevus syndrome (BRBNS), an extremely rare disease, is characterized by multiple venous malformations (VMs) that characteristically occur on the skin of the whole body and mucosa of the gastrointestinal system. Chronic anemia is caused by

Multifocal Blue Nevus of the Conjunctiva
Survey of Ophthalmology, 2008Blue nevus is a congenital benign melanocytic tumor that classically occurs in the skin and carries low potential for malignant transformation. We report an unusual case of widely dispersed multifocal common blue nevus of the conjunctiva simulating conjunctival melanoma.

A 36‐year‐old man presented with a subcutaneous nodule on the right upper arm. A small nodule had developed 8 years earlier, and grew in size, accompanied by a tingling sensation and numbness.

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.

Melanoma ex blue nevus (MEBN) is a rare, aggressive, and potentially lethal neoplasm. Distinguishing MEBN from an atypical cellular blue nevus can be very challenging. We report a diagnostically difficult case of MEBN with lymph node metastases, in which

‘Atypical’ Blue Nevus – a Benign Variant of Cellular Blue Nevus
Dermatology, 1977Three cases of ‘atypical’ blue nevus presented almost identical histological findings differing from both benign cellular blue nevus and malignant blue nevus or malignant melanoma, and suggesting malignancy. Long-term follow-up – in one case 19 years – indicates that this pigmented tumor is a benign variant of blue nevus.

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.

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 may rarely appear in plaque form. It seems to be a benign and asymptomatic lesion, but because of its rarity, no definite prognosis can be given. Only through reporting of additional cases and their follow-up will the prognosis become clear.
