Kaposi`s sarcoma is vascular neoplasia, with purplish, infiltrative lesions and the possibility of affecting the viscera or lymph nodes, that can be classified into 4 categories: epidemic (related to HIV infection), classical (elderly men in the Mediterranean basin), endemic (Africa) and iatrogenic (immunosuppressive therapy). Case presentation Will illustrate the case of a 69-year-old man, without personal pathological history, who came to the consultation for an erythematous– slightly purplish plaque, glossy, supple, mobile, well defined, irregular in shape, with a diameter of 5 cm located at the level of the foreskin, with a 2-month onset, asymptomatic. The presumptive clinical diagnosis was nonspecific balanitis and we recommend treatment with local corticosteroids. After 30 days, at the follow-up visit, the appearance of the lesion was stationary. We rethink the clinical diagnosis with the suspicion of Zoon balanitis or Queirat erythroplasia. By mutual agreement with the patient, it was decided to perform a punch biopsy, which confirmed the diagnosis of Zoon balanitis. We described the therapeutic options to the patient, but he refused any therapeutic alternative, preferring the follow-up attitude. After another 7 months, the patient presented in our clinic for the appearance of new, nodular, purplish lesions, with a maximum diameter of 0.5cm, perilesional, and a detailed clinical examination also notes the existence of violet nodules with a diameter of 0.5 cm located on the right leg. This time we established the diagnosis of Kaposi`s sarcoma. For a certain diagnosis, we excised a gambier node, and the rest of the nodules were removed with electrocautery. The patient was referred to the oncology service for extensive clinical-paraclinical evaluation.
