Lobomycosis and squamous cell carcinoma * Lobomicose e carcinoma espinocelular

Abstract: The occurence of squamous cell carcinoma on long-lasting ulcers is classic. Malignant transformationmay occur on burn scars and chronic ulcers of varying etiology, including infectious agents. Transformation ofold lobomycosis lesion scars into squamous cell carcinoma has been rarely reported. Careful and long-term fol-low-up of such patients is important to avoid carcinomatous transformation.Keywords: Bacterial infections and mycoses; Carcinoma, squamous cell; Leg ulcer; Skin ulcer; Mycoses Resumo: A ocorrencia de carcinoma espinocelular sobre lesoes cutâneas de longa evolucao e classica em cicatri-zes de queimadura e ulceras cronicas de etiologia variada, inclusive infecciosa.
