چکیده
Figure 1. Preoperative photograph showing the overlying melanocytic nevi. DESCRIPTION We present a 13-year-old male patient with congenital melanocytic nevi and a yearlong history of enlarging right preauricular mass. Examination revealed 2 congenital melanocytic nevi overlying a large, firm, mobile 2.7 × 2.5-cm subcutaneous mass with irregular borders. Pathology confirmed intradermal melanocytic nevi; the underlying mass was a calcified and ossified pilomatrixoma.

The risk of melanoma and neurocutaneous melanosis associated with congenital melanocytic nevi.
Congenital melanocytic nevi are commonly encountered in clinical practice. Although the development of malignant melanoma arising in small and intermediate congenital melanocytic nevi is rare, there is a significant risk of malignant degeneration associated with large congenital melanocytic nevi, in particular those that arise on the torso in the so-called "bathing trunk" distribution, where th...
متن کاملRisk of melanoma arising in large congenital melanocytic nevi: a systematic review.
Large congenital melanocytic nevi are cutaneous lesions regarded by many as premalignant; estimates of malignancy incidence range from 0 to 42 percent. Given the often complex and extensive nature of large congenital melanocytic nevi resection and reconstruction, the risk of malignant transformation is a crucial factor that surgeons and families must weigh when deciding whether or not to excise...

Background: This case report presents a very rare Dandy-Walker malformation (DWM) in association with a sporadic condition characterized by congenital melanocytic nevi and melanocytic thickening of the leptomeninges called Neurocutaneous melanosis (NCM). The DWM is a rare congenital disorder characterized by enlarged posterior fossa and a cystic enlargement of the four...

Dear Editor-in-ChiefMalignant melanoma is a tumor arising from melanocyte; this tumor rarely occurs before puberty, with higher mortality rate in males and better survival rate in female patients affected by metastatic melanoma (1, 2). These facts propose that a relationship and association may exist between estrogens and melanoma. The effects of estrogens are mediated by...
متن کاملPigmented Skin Lesions in Children (Melanocytic Nevus, Clonal Nevus and Halo Nevus) — Symptoms and Treatment
Benign pigmented skin lesions are very common in children and can be generally classified into congenital or acquired nevi. Congenital nevi can be small, medium or large. Large nevi are usually associated with a higher risk of malignant transformation into melanoma. Acquired melanocytic nevi can be classified into typical melanocytic nevi, clonal nevi, or halo nevi. Cytological atypia can be ob...
