Is a blue nevus cancerous?

Although most cases of blue nevi are benign, there is a small possibility that a cellular blue nevus can undergo malignant transformation and become a malignant cellular blue nevus (MCBN). Thus, a biopsy of any changing or suspicious lesion should be done.

Is blue nevus serious?

A common blue nevus is usually benign, remains unchanged throughout life, and does not lead to any complications. In rare situations, a cellular blue nevus may develop into a form of melanoma called a malignant cellular blue nevus.

Should a blue nevus be removed?

A blue nevus typically isn’t problematic. You can have a benign blue nevus on your skin for your entire lifetime. The only time your doctor will recommend removal is if the mole is malignant. You can also talk to your doctor about removal if the mole is causing you discomfort.

Should Cellular blue nevi be excised?

Blue nevi are benign lesions and do not need to be excised if the diagnosis is clear. If there is a question about the diagnosis, an excisional biopsy attempting to remove the entire lesion could be considered. The melanocytes of a blue nevus are often quite deep and a shave biopsy may transect the lesion.

What is a cellular blue nevus?

Blue nevus is a benign melanocytic lesion whose most frequent variants are dendritic (common) blue nevus and cellular blue nevus. Atypical cellular blue nevus presents an intermediate histopathology between the typical and a rare variant of malignant blue nevus/melanoma arising in a cellular blue nevus.

Can blue nevus spread?

Differential diagnosis includes cellular blue nevus, atypical cellular blue nevus, primary malignant melanoma, and metastatic melanoma to the dermis. Malignant blue nevus is most commonly seen on the scalp. The tumor has an aggressive behavior and metastasizes in the majority of patients.

Can a blue nevus appear suddenly?

Sudden change in a pigmented lesion accompanied by the appearance of new lesions is a cause for concern for potential melanoma development. Here we present such a case, diagnosed as eruptive blue nevi in a young woman. This case highlights the importance of dermoscopy for the diagnosis of this rare phenomenon.

What is atypical cellular blue nevus?

Atypical cellular blue nevus presents an intermediate histopathology between the typical and a rare variant of malignant blue nevus/melanoma arising in a cellular blue nevus. An 8-year-old child presented a pigmented lesion in the buttock since birth, but with progressive growth in the last two years.

What is the pathophysiology of blue nevus?

Blue nevus is a benign melanocytic lesion whose most frequent variants are dendritic (common) blue nevus and cellular blue nevus. Atypical cellular blue nevus presents an intermediate histopathology between the typical and a rare variant of malignant blue nevus/melanoma arising in a cellular blue nevus.

Can a cellular blue nevus turn into cancer?

However, in rare cases, a Cellular Blue Nevus can transform into a melanoma (a malignant skin cancer). Due to this factor, the nevus is typically removed through a surgery. In some individuals, it may give rise to cosmetic concerns. Scratching or itching of the moles may lead to bleeding and ulceration.

What are the treatment measures for cellular blue nevus?

The treatment measures for Cellular Blue Nevus include: 1 Surgical excision and removal of the mole 2 Blue Nevus can also be excised through electrocautery surgical procedure 3 Regular follow up visits may be recommended by the healthcare provider
