CADENA-PINEROS, Enrique  e  ROLON-CADENA, Mariam Carolina. Sentinel ganglion in melanoma of the face: an initial approach. rev.fac.med. [online]. 2012, vol.60, n.3, pp.241-246. ISSN 0120-0011.

In spite of preventative campaigns having been mounted, it still has not been possible to reduce cutaneous neoplasia incidence, probably due to alterations in the ozone layer. This has led to a consequent increase in ultraviolet radiation and thus lesions occurring in tropical countries such as skin cancer (melanoma), considered as being one of the most aggressive tumour lesions. The face and neck are the body areas having the highest exposure to the sun, being reflected in a greater number of such tumour cases. The presence of ganglion metastasis is the greatest negative prognostic factor for patients suffering from this disease; the treating group must thus clarify whether this is present as prophylactic neck dissections were made several decades ago, but the ganglions so removed were negative in most cases. Extracting the first ganglions draining the primary tumour site (sentinel ganglion) represents a possible solution for avoiding this. Several of them are usually present at the same time in the head and neck area, thereby hampering taking a decision as to which should be removed. Our group has begun to standardise such technique; an initial approach has involved the first case of a patient with melanoma of the face who underwent wide local resection of the tumour and extraction of the sentinel ganglions. These were dyed and lymphogammagraphy was used, at the same time as dissection of positive ganglion relief for drainage, as demonstrated by this nuclear medicine study.
