OBJECTIVES: Few epidemiological studies have analyzed cutaneous head and neck melanoma (CHNM) in the Spanish population. The aim of this study was to describe the clinical and histologic features of a representative sample of CHNM in Spain and to analyze changes observed over a period of 21 years.
MATERIAL AND METHODS: Descriptive, retrospective, cross-sectional study of 280 patients diagnosed with CHNM at Hospital General Universitario Gregorio Marañón in Madrid, Spain, between January 1, 1995, and December 31, 2015. The main clinical and histologic features were analyzed and compared between 3 periods: 1995-2001, 2002-2008, and 2009-2015.
RESULTS: Mean age at diagnosis was 71.3 years (median, 74 years; interquartile range [IQR], 65-81 years). The most common location was the face, followed by the scalp. The main histologic subtype was lentigo maligna (n=172, 64%). Mean tumor thickness was 1.6 mm (median, 0.4mm; IQR, 0-2.1mm). Median follow-up was 111 months; in this time 51 patients experienced CHNM recurrence (18.2%) and 29 died of the disease (10.4%). In the years analyzed, we observed a significant increase in the number and percentage of patients aged 75 years or older (P=.001) and in the percentage of melanomas in situ (P=.003). We also observed a significant decrease in mean tumor thickness (P=.018), the number of cases with 6 or more mitotic figures (P=.013), the percentage of patients with metastasis (P=.014), and melanoma-specific mortality (P=.005).
CONCLUSIONS: CHNM affects elderly patients and is preferentially located on the face. The predominant subtype is lentigo maligna. Patients presented with thinner tumors over time and are now less likely to develop metastasis and to die of melanoma.
