Resumo

We present a challenging case of HIV-related lymphangioma-like Kaposi sarcoma (LLKS) affecting the oral cavity. A 54-year-old Brazilian male patient was referred to our center complaining of bleeding lesions affecting the oral cavity for 2 months. Interestingly, these oral lesions were the first clinical manifestation of HIV infection. Clinically, multiple erythematous nodular and patch lesions were observed. An incisional biopsy was performed, revealing numerous microscopic angled and irregular vascular channels lined with flattened endothelial cells. More cellularized and solid areas consisting of more fusiform cells with little pleomorphism and with slit-like vascular channels were noted. Based on immunoreactivity for CD31, CD34, D2-40, and HHV-8, the final diagnosis was oral LLKS. Highly active antiretroviral therapy (HAART) was initiated with dolutegravir, tenofovir, and lamivudine. During follow-up, the patient showed KS metastases to other sites and a chemotherapeutic protocol was initiated. Regression of the oral lesion was clearly noted by the clinicians 1 year after the KS diagnosis. Dentists should be able to recognize systemic diseases that affect the oral cavity such as KS in order to make an early diagnosis of its oral manifestations and to implement effective therapeutic measures to ensure a better prognosis.
