Trichomycosis Pubis: A Reason Behind Bad Smell Down There

October 19, 2014 By Dr.Deepak Ghimire 2 Comments

Trichomycosis Pubis is a superficial bacterial infection of the hair shaft of the pubic region. This is more common in axilla and we call it trichomycosis axillaris. Besides foul odor, there are no any symptoms, so most of the individuals don’t visit dermatologist.

What causes Trichomycosis Pubis?

Trichomycosis pubis is caused by overgrowth of bacteria called corynebacterium tenuis. Warm, moist environment, excessive sweating and poor local hygiene are common predisposing factors for trichomycosis pubis. In contrast to the name this is not caused my fungus but bacteria. Thus, the term “trichomycosis” is a misnomer and may now better be called as trichobacteriosis.

How does Trichomycosis Pubis look like?

Patients with trichomycosis pubis usually present with yellow, black or red nodular concentration on their hair shafts; yellow is most common. Sweat in the region tends to be colored similarly. Lesions most commonly present on scrotal region but can be seen in the inguinal region and on the base of the shaft of the penis. Although in most cases there is no symptom at all, but can be associated with itching, redness and secondary fungal infection.

How is it diagnosed?

The condition is easily diagnosed bases on direct clinical findings. If in confusion, laboratory gram stain preparation can easily recognize the concentration of bacteria Corynebacterium tenuis. Wood’s light examination can also reveal pale-yellow fluorescence.

How can it be treated?

The simple and effective home treatment is to shave the affected hair. Vigorous rubbing of the affected hair while washing is also another way of removing the colonization of bacteria. Washing with benzoyl peroxide wash is another effective treatment option. Other effective options include topical applications of creams, ointments and gels containing clindamycin, erythromycin or benzyl peroxide. In severe and chronic cases regular use of topical ammonium chloride solution and drying powders may prevent further recurrences. The outcome of the treatment is very good and recurrence is uncommon if maintained good hygiene.

      Reason is because the bacteria employ testosterone in th sweat to make the smell. See more on Wikipedia about it.
