1 It has been estimated that 290,000 new cases and 61,000 deaths were recorded worldwide in 2018. 1,2 According to the Brazilian National Cancer Institute (INCA, Instituto Nacional do Câncer) estimates, by 2020 8450 new cases of cutaneous melanoma are predicted in the country, of which 4200 may occur in men and 4250 in women. The number of cases of the disease increases each year in Brazil and worldwide. Melanoma is the most lethal malignant skin tumor. The mitotic index was important for prognosis prediction. The frequency of positive sentinel lymph node biopsy in patients with malignant melanoma of the head and neck was lower than in other studies, although the sample consisted of individuals with advanced melanomas. The mean survival for patients with a mitotic index 3.5. Malar location showed a protective effect on prognosis. Positivity was associated with Clark and Breslow levels. The mean Breslow index was 11.3 mm for primary melanomas with positive sentinel lymph nodes and 4.3 mm for those with negative sentinel lymph nodes. Deaths were recorded in two of the cases with positive sentinel lymph nodes (66.6%), and in 5 (17.8%) of the patients with negative lymph nodes. Among the 31 patients undergoing sentinel lymph node biopsy, 3 had positive sentinel lymph nodes (9.7%). Clark, Breslow and mitotic index were predictors of death. Of the 49 patients, 5 had cervical metastasis at the moment of admission. From 2009 to 2014, 49 patients with cutaneous melanoma of the head and neck underwent surgery at Instituto do Câncer do Estado de São Paulo (ICESP). To evaluate the technical aspects, positivity and prognostic effect of the cervico-facial sentinel lymph node biopsy. Sentinel lymph node biopsy is the gold standard procedure for head and neck cutaneous melanoma staging.
