Unexpected Acute Necrotizing Ulcerative Gingivitis in a Well-controlled HIV-infected Case.

ABSTRACT

We herein report the case of a 41-year-old Japanese man with well-controlled HIV who presented with diagnostically difficult acute necrotizing ulcerative gingivitis (ANUG). After diet-induced weight loss, he developed oral pain and disturbance of mouth opening, and was admitted to our hospital. Based on preconceptions of HIV-associated diseases, fluconazole was initiated for candidiasis. However, no improvement was seen and ANUG was finally diagnosed. This case suggests that physicians should consider ANUG in HIV-infected individuals when several risk factors are present, even if CD4+ T-lymphocyte counts have remained stable owing to long-term anti-retroviral therapy.
