Abstract:
Malignant melanoma is a relatively rare but potentially aggressive tumor in children and adolescents. We report the case of a metastatic malignant melanoma in a 17-year-old girl, first diagnosed on cytological features of a fine-needle lymph node aspiration and then histologically confirmed by both examination of the metastatic adenopathy and a clinically harmless skin lesion of the scalp, which harbored focal microscopic pattern of melanoma. A fluorescent in situ hybridization study revealed that both metastatic and primary cutaneous tumours contained the same and pejorative chromosomal aberration consisting in CCND1 amplification (11q13). This observation raises actual limits and challenges in the fields of diagnosis and treatment of fast-killing melanomas.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
