AI Article Synopsis
- Favus is a rare chronic scalp infection primarily affecting children, though some adult cases exist, featuring yellowish plaques and hair loss.
- An adult patient presented with a non-scalp lesion resembling psoriasis in the forehead area, which led to a diagnostic challenge after she declined a biopsy.
- Diagnosis was confirmed using potassium hydroxide stains, and treatment with itraconazole led to complete recovery, highlighting the importance of basic diagnostic methods in limited-resource environments.
Article Abstract
Favus is an uncommon chronic inflammatory dermatophyte infection of the scalp. Predominantly, a disease of childhood, uncommon reports of adult cases are described. For the most part, this infection is characterised by invasion of hair shaft clinically presenting as yellowish scaly plaques, alopecia and/or inflammatory lesions. We hereby present an immunocompetent adult presenting with a psoriasiform plaque over glabella, culturally referred to as 'bindi' area. No involvement of the scalp or other hair-borne areas was seen. As she did not agree to undergo a skin biopsy, a last resort of simple stains like potassium hydroxide was done confirming favus. Systemic itraconazole was initiated and complete clinical and mycological resolution was seen with no relapse. Such atypical presentations in adults can cause a diagnostic dilemma and simple stains still hold their ground in making a diagnosis in resource-poor settings.
