Invasive melanomas may be detected as small-diameter lesions and are potentially metastatic, according to study findings published in Journal of the American Academy of Dermatology.
Researchers conducted a retrospective study using patient data from the European Association of Dermato-Oncology database. They evaluated invasive melanomas of the nodular melanoma or superficial spreading melanoma subtype that had a maximum diameter of 6 mm on histologic sections diagnosed between 2006 and 2015.
Follow-up for small-diameter melanomas was conducted until 2022. Multivariate logistic regression and Kaplan-Meier estimator were used to analyze metastasis.
