History
Women
Trichomoniasis symptoms in women range from none to severe pelvic inflammatory disease. Women with trichomoniasis frequently report a frothy yellowish-green vaginal discharge, abnormal vaginal odor, vulvovaginal itching and soreness, dyspareunia (pain during sexual intercourse), and dysuria (pain during urination). However, many infected women experience no symptoms.
Cervicitis due to trichomoniasis is characterized by 2 major signs—purulent discharge in the endocervical canal and easily induced endocervical bleeding.[2] However, it may also be asymptomatic.
T vaginalis infection is one of the top 3 causes of vaginitis.[2] Vaginitis is usually characterized by vaginal discharge, which may be accompanied by vulvar itching, irritation, and odor. The two other most common causes of vaginal discharge are anaerobic bacterial overgrowth of normal flora and candidiasis (infection with Candida albicans).[2]
Men
Trichomoniasis symptoms in men range from none to urethritis complicated by prostatitis. Nongonococcal nonchlamydial urethritis is the most common symptom reported by men with trichomoniasis. Symptoms of urethritis include discharge, dysuria, and urethral pruritus.[2] The discharge may be purulent to mucoid in character. Most symptomatic infections are intermittent and self-limiting. Complications of untreated trichomoniasis include prostatitis, epididymitis, urethral stricture disease, and infertility.
Physical
Women
- Purulent or homogenous vaginal discharge and vulvar or vaginal erythema are common.
- Colpitis macularis, or strawberry cervix, describes a diffuse or patchy macular erythematous lesion of the cervix. This is a specific sign for trichomoniasis but is visible in only 1-2% of cases without the aid of colposcopy. With colposcopy, colpitis macularis is detected in up to 45% of cases.
- Lower-abdominal tenderness may be present; however, this is described in fewer than 10% of patients. If this occurs, coexisting salpingitis or an intra-abdominal pathology is possible.
- Coexisting Neisseria gonorrhea infection, candidiasis, and bacterial vaginosis are common and may produce a mixed clinical picture.
Men
- The findings of trichomoniasis in men on physical examination are generally unremarkable unless the infection is complicated. It may be associated with local inflammatory states, including balanitis and balanoposthitis.
- Physical findings of epididymitis and prostatitis may also occur.
