OSTEOMA CUTIS ASSOCIATED WITH CHRONIC DERMATITIS CAUSED BY SUCCESSIVE INFLAMMATORY PROCESSES: CASE REPORT

Abstract

Osteoma cutis is a rare disease characterized by the presence of bone tissue in the layer of the dermis and hypodermis. It has uncertain etiopathogenesis, which is based on two main theories, the embryological disorder with accumulation of mesenchymal cells that differentiate into osteoblasts and the theory of the phenomenon of metaplasia of mesenchymal cells that directly form fibroblasts that produce bone tissue in anomalous sites. One of its possible etiologies is chronic inflammation caused by other conditions. This report presents the case of a 55-year-old patient who presented osteoma cutis, with a history of dermatological lesions associated with significant exposure to the sun, which gradually evolved over time.  With emphasis on the lesions: non-granulomatous rosacea and acne. The objective of this report is to describe the course of the disease and its clinical-histological characteristics. The report describes the course of the disease and discusses relating to risk factors and progression with chronicity, but lacks different sources on the disease, thus illustrating the need for further studies on the subject to elucidate the outcome of the disease.
