ABSTRACT.

Clinical skin manifestations are commonly seen in resource-limited settings, but they are frequently misdiagnosed due to the lack of microbiological tests with ensuing stigma and long-term disability. The adoption of portable ultrasound devices, which extend physical examination in the hands of trained clinicians, has partially improved the situation. Specific protocols, such as focused assessment with sonography for HIV-associated tuberculosis (FASH), have led to simplified diagnostic pathways. Here we describe a case of bacillary angiomatosis in a patient with advanced HIV disease presenting with subacute unusual cutaneous lesions. The patient also presented with significant weight loss, anemia, and prostration. Highly sensitive rapid tests for tuberculosis and cryptococcosis were negative, and CD4 count was very low. Ultrasound scanning (US) and biopsy of the cutaneous lesions finally led to diagnosis and treatment. This report illustrates the benefits of integrating ultrasound-based protocols with clinical skills, as the diagnosis was suspected based on clinical presentation and US and confirmed by pathology. The importance of adoption of US protocols by infectious diseases clinicians is discussed.
