Relación clínica-dermatoscópica-histológica de lesiones pigmentadas de piel sugestiva de melanoma

Abstract

Introduction: among neoplastic diseases, skin diseases have the highest incidence in adults; of this group, malignant melanoma is the one with the highest lethality. The differential diagnosis with other pigmented skin lesions is based on clinical, dermatoscopic and histological findings. Objective: to describe the clinical-dermatoscopic-histological correlations of pigmented skin lesions suggestive of melanoma in patients seen at the "Celestino Hernández" Hospital in the period from September 2018 to September 2019. Methods: a descriptive, longitudinal, prospective study was conducted. The population was constituted by the total number of patients assisted at the Peripheral Tumor Consultation with pigmented lesions and clinical diagnosis of malignant melanoma. The sample consisted of 57 patients who underwent dermoscopy and biopsy. Results: the mean age was 57.8±13.8 years. The clinical, dermoscopic and histological diagnosis of malignant melanoma corresponded in 56.14% of patients. Dermoscopy was corroborated as a valuable study for the diagnosis of melanoma. Conclusions: the diagnosis of pigmented skin lesions suggestive of melanoma predominated in patients older than 60 years and female sex, with predominance of skin phototypes II and III. The lesions were most frequently located on the lower limbs, in contrast to cases with non-melanoma lesions located on the thorax, head and neck. Dermoscopy was of great importance in the diagnosis of melanoma and supported the clinical diagnosis to rule out false positives.
