Sex- and Site-Related Significance in Cutaneous Head and Neck Melanoma.

Cutaneous head and neck melanoma is a separate subgroup of cutaneous melanoma that has a worse prognosis than other primary sites. The aim of this article is to examine the significance of sex and site of primary lesion as additional risk factors. Primary localization distribution and metastatic disease in the neck in a retrospective cohort of 159 patients with cutaneous head and neck malignant melanoma were analyzed. Men develop primary melanoma more frequently than women in the left peripheral head and neck regions ( = .0364), as well as clinically visible and occult metastatic disease in the left side of the neck ( = .0138). Patients with clinically occult regional metastatic disease showed a significantly poorer survival rate than the rest of the group that underwent elective neck dissections ( = .0270). Left-sided disease in male patients may be an additional risk factor in cutaneous head and neck melanoma. Performing elective neck dissections in high-risk patients might identify patients with occult metastatic disease and worse prognosis but does not offer any significant therapeutic benefit.
