Trichomycosis Pubis Clinical Presentation
- Author: Vladimir O Osipov, MD; Chief Editor: Dirk M Elston, MD more...
While many patients are asymptomatic, patients have presented because of pubic rash, foul odor, or growths on the pubic hair. Presenting complaints of colored sweat also have been recorded, resulting in a consideration of chromhidrosis.
Patients typically present with yellow or red nodules on the hair shafts; yellow is most common. Sweat in the region tends to be colored similarly. Lesions present in the inguinal region, often on the scrotum but occasionally on the base of the shaft of the penis. Lesions can be associated with erythema and itching, and superinfection with dermatophytes has been noted.
Risk factors appear to be geographic, with the highest incidence in tropic areas. In addition, poor hygiene often is present.
Other diagnostic considerations
Clinical separation from other organisms often is not performed, and treatment focuses on the empirical use of drying agents and topical antibiotics. Thus, the use of topical powders can be a confounding factor in diagnosis. True fungal infections (piedra) also may confound the diagnosis but may be present as superinfection. Piedra presents with nodularity of the hair shafts that is either tan to white (white piedra) or black (black piedra), as opposed to the yellow or red nodules of trichomycosis. White piedra may have a gelatinous appearance.
