Caracterizacion clinica y dermatoscopica del dermatofibroma

Abstract

Dermatofibroma is a benign skin tumor that manifests as a small, firm and painless lesion on the skin, originating in the subcutaneous cellular tissue, mainly in middle-aged adults and usually located on the face and neck. The most common clinical presentation is a solitary, asymptomatic, small, brownish nodule. These tumors appear spontaneously on the skin, manifesting as small nodules up to 3 cm in diameter, brown in color, which can be palpated, which raises a differential diagnosis with malignant neoplasms such as dermatofibrosarcoma protuberans, malignant fibrous histiocytoma and hemangiopericytoma: they are found as single, asymptomatic lesions, frequently appearing after trauma or insect bites. It is a localized lesion, which does not reproduce or metastasize to other organs of the body. The treatment is surgical resection, although due to the benignity of this lesion, it is not necessary. Objective: To evaluate the dermoscopic characteristics and patterns of dermatofibromas for their correct diagnosis and management. Methodology: This descriptive study was carried out by reviewing scientific articles and correlation of clinical cases updated in the last 5 years, using search engines such as Google academy, Pubmed, Redalyc, Scielo, Dialnet, which allowed us to collect information on the characteristics of dermatofibroma for diagnosis. Conclusion: We were able to determine the different types of dermatofibroma with its clinical characteristics evidencing different diagnostic techniques that help us with the identification of the lesion.
