Resumen: A 53-year-old woman with a history of arterial hypertension, diabetes mellitus, and morbid obesity presented with abdominal lesions persisting for 3 months and resistant to previous treatment. Physical examination revealed characteristic erythematous-violaceous plaques with serpiginous distribution and central ulceration. Histological examination confirmed diffuse dermal angiomatosis with underlying fat tissue necrosis, a rare association. Diffuse dermal angiomatosis typically affects middle-aged women with cardiovascular risk factors, and treatment involves addressing underlying vascular alterations.
