Introduction: aynchronous melanomas are defined as the presence of two or more melanomas in an individual at the same time, or the appearance of a second melanoma up to one month after the diagnosis of the first one.
Objectives: to determine the epidemiological, clinical, dermoscopic, and histological characteristics of synchronous melanomas in patients at Hospital El Carmen.
Design: descriptive, retrospective, observational, and cross-sectional study.
Materials and methods: patients with synchronous melanomas evaluated at the Dermatology Department from June 2022 to July 2023 were selected.
Results: of the 37 melanomas detected during the study period, 37.84% (n=14) were synchronous melanomas, corresponding to 5 patients. The mean age at diagnosis was 61.8 years (±13.2). 60% were females and 40% males. 42.9% were located on the trunk, 35.7% on lower limbs, 14.3% on upper limbs, and 7.1% on head and neck. 80% of synchronous melanomas were found in the same anatomical region. Dermoscopic patterns were similar in 80% of patients' synchronous melanomas. Histologically, 6 were in situ, 6 were superficial spreading melanomas, and two were nodular melanomas.
Conclusions: it is important to conduct a total body examination on patients and we emphasize that it should not be interrupted when a suspicious lesion is found. This study demonstrates that synchronous melanomas are located in the same anatomical region and present similar dermoscopic and histological characteristics in the same individual. This underscores the need for a thorough evaluation to detect possible synchronous melanomas.
