Mycotic infections of the adult male beard are not common in this country. Most of the reported cases are caused by one of the Trichophyta, usually Trichophyton mentagrophytes, but Microsporum lanosum is one of the organisms mentioned in the various dermatology and mycology texts. Sabouraud1 states that he was able to culture M. lanosum in only three cases involving the beard of adult man.
Miguens,2 from Spain, writes the only description of a case of tinea barbae due to M. lanosum which could be found in the literature. He cites Mackinson3 as finding one other case. Miguens' patient was a 28-year-old man, and from the clinical description resembled our case closely. His patient apparently acquired the infection from a calf. No description of a case from the United States could be found.
