favus
Noun: A specific, contagious fungal disease affecting the scalp and sometimes the skin or nails, characterized by the formation of yellow, cup-shaped crusts and potentially leading to scarring and permanent hair loss. It is caused by fungi of the genus Trichophyton.
The word "favus" is a medical/clinical term. It is used as a singular, countable noun to name the disease itself. * Diagnosis: "The dermatologist confirmed a case of favus." * General reference: "Favus is less common in industrialized nations."
- The distinctive yellow crusts, known as scutula, are a hallmark of favus.
- Before modern antifungals, favus was a major cause of scarring alopecia in endemic regions.

- The term can be used attributively (like an adjective) to describe related concepts, e.g., "favus infection," "favus lesions."
