Presentation

History

While many patients are asymptomatic, patients may present with reports of pubic rash, foul odor, or growths on the pubic hair. Colored sweat also has also been reported, resulting in a consideration of chromhidrosis.

Physical Examination

Patients typically present with yellow, red, or black nodules or fine sheaths consisting of a bacterial biofilm encasing the hair shafts [8] ; yellow is most common, present in 95-98% of cases. [10] Sweat in the region tends to be colored similarly. Lesions present in the inguinal region are 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.

Complications

The primary complication appears in individuals who are immunocompromised and can develop septicemia secondary to colonization of catheters and surgical sites. Infection in hosts who are immunocompetent yields few long-term adverse effects.

Recurrence is common, but the simplicity of treatment and improved hygiene make follow-up care simple. In rare cases, shaving the pubic hair after treatment has been advocated to prevent recurrences.
