Abstract
Malignant melanoma in childhood is infrequent and can arise within congenital melanocytic nevi. Spread of malignant melanoma to the bone marrow, especially in children, is extremely rare. Reported is a case of a 5-year-old boy with a congenital large melanocytic nevus of the head and neck who presented with a short history of low back and leg pain, fever and cervical lymphadenopathy. Despite regular follow-up by a dermatologist and plastic surgeon and repeatedly negative histology of previous partial excisions, diffuse bone marrow infiltration with malignant melanoma was diagnosed. The primary site was identified in the post-excision area. The disease progressed rapidly on ipilimumab immunotherapy and led to death at four months from the diagnosis. Surveillance is indispensable in children with a predisposition to melanoma and nonspecific symptoms such as bone pain, gait impairment or cytopenia, should always be taken into account.

BackgroundMalignant melanoma in childhood is infrequent and can arise within congenital melanocytic nevi
In spite of recent diagnostic and therapeutic advances, metastatic malignant melanoma is a serious disease with poor prognosis in both children and adults
We report a rare case of a 5-year-old boy with a large congenital melanocytic nevus of the head and neck who presented with malignant melanoma metastasizing to the bone marrow
