Oral Localization of Kaposi Sarcoma: Clinical Presentation and Conservative Management

Oral Kaposi sarcoma development is associated with HIV viral load, CD4+ count and CD4+/CD8+ ratio

Background

Kaposi’s sarcoma (KS) is an uncommon, multifocal and angioproliferative lesion, which demonstrates a poor prognosis. The aim of the present research was to explore the association of HIV viral load, CD4+ and CD8+ counts and the CD4+/CD8+ ratio on the risk of oral Kaposi’s sarcoma (KS) development.

Material and Methods

A total of 62 patients were retrieved from March 2008 to October 2020 from the files of two oral pathology centres. Clinical, laboratory and follow-up data were retrieved from their medical files. Poisson regression was used to explore the role of history of immunosuppression and its association with oral KS development. A P-value <0.05 was considered significant.

Results

Sixty-two patients were included in the present study (32 with oral KS and 30 with no presentation of lesions anywhere on the body). Patients with oral KS presented a mean age of 32.6 years, and male patients were more affected. The hard palate (15 cases; 46.8%) was the main anatomical site affected. The lesions were mostly presented as swellings (13 cases; 40.6%) and nodules (12 cases; 37.5%). Systemic manifestations were also observed, including candidiasis (4 cases; 12.5%), bacterial infection (3 cases; 9.3%), tuberculosis (3 cases; 9.3%), herpes simplex (3 cases; 9.3%) and pneumonia (3 cases; 9.3%). A significant correlation was observed between HIV viral load, CD4+ count and the CD4+/CD8+ ratio with oral KS development.

Conclusions

HIV viral load, CD4+ count and the CD4+/CD8+ ratio are associated with oral KS development.

Oral manifestations in stem cell transplantation for acute myeloid leukemia

Acute myeloid leukemia is a highly aggressive malignancy with a high morbidity rate, for which an accurate and rapid diagnostic is essential. Acute myeloid leukemia manifestations frequently include oral abnormalities. Still, there is a limited number of studies reporting the incidence of oral manifestations in acute leukemia, the prevalence of periodontal status and periodontal parameters in these patients. Our aim was to emphasize the importance of early recognition by the dental practitioners of oral cavity manifestations as signs of acute myeloid leukemia, so that prompt referral to the hematologists is being done, and appropriate treatment is offered.
