Abstract
Melanoma arising in blue nevus, also known as melanoma ex blue nevus, is a specific form of melanoma whose genetic profile is different to that of other cutaneous melanomas and surprisingly similar to that of uveal melanoma. Although melanoma ex blue nevus can appear de novo, it usually arises in a pre-existing blue nevus or dermal melanocytosis. Not all nodular lesions arising in association with blue nevus or dermal melanocytosis are melanomas, however, and because clinical and histologic findings may be insufficient for a definitive diagnosis, additional studies such as comparative genomic hybridization are important. Detection of chromosomal aberrations supports a diagnosis of malignancy. Studies of the BAP1 gene are particularly useful in this setting because loss of expression is indicative of melanoma. We present 3 cases on the spectrum of blue nevus to melanoma ex blue nevus that were studied using molecular biology techniques.El melanoma sobre nevus azul o melanoma ex-blue nevus es una variedad de melanoma peculiar que tiene un perfil genético diferente al del resto de los melanomas cutáneos y sorprendentemente superponible al perfil del melanoma uveal. Aunque puede aparecer de novo, el melanoma ex-blue nevus se suele desarrollar sobre un nevus azul previo o sobre una melanocitosis dérmica. No todas las lesiones nodulares desarrolladas sobre un nevus azul o una melanocitosis dérmica son melanomas, y los hallazgos clínicos e histológicos pueden ser insuficientes para llegar a un diagnóstico de certeza. Así, cobran relevancia estudios adicionales, como la hibridación genómica comparada, pues la presencia de aberraciones cromosómicas favorece el diagnóstico de malignidad. Es de especial utilidad el estudio del gen BAP1, cuya pérdida de expresión orienta a melanoma en este espectro de lesiones. Presentamos tres casos del espectro nevus azul a melanoma ex-blue nevus con estudios de biología molecular.
