Пахова гранульома

Sites of infection include the following:

• Penis, scrotum, groin, and thighs in men

• Vulva, vagina, and perineum in women

• Anus and buttocks in patients who engage in anal-receptive intercourse

• Face in both sexes

After an incubation period of about 1 to 12 weeks, a painless, red skin nodule slowly enlarges, becoming a raised, beefy red, moist, smooth, foul-smelling lesion. The lesion slowly enlarges, often ulcerates, and may spread to other skin areas. Lesions heal slowly, with scarring.

Secondary infections with other bacteria are common and can cause extensive tissue destruction.

Lymphadenopathy is uncommon.

Occasionally, granuloma inguinale spreads through the bloodstream to the bones, joints, or liver; without treatment, anemia, wasting, and, uncommonly, death may occur.

Granuloma Inguinale (Chronic Genital Lesions)

Granuloma inguinale is a progressive ulcerative disease that is usually sexually transmitted and involves the skin and subcutaneous tissues in the anogenital and inguinal regions. The initial nodule slowly enlarges, erodes the surrounding tissues, and develops into a beefy, bulky, granulomatous mass.

• Physical examination

• Microscopic examination showing Donovan bodies in fluid from a lesion

Granuloma inguinale is suspected in patients from endemic areas with characteristic lesions.

Diagnosis of granuloma inguinale is confirmed microscopically by the presence of Donovan bodies (numerous bacilli in the cytoplasm of macrophages shown by Giemsa or Wright stain) in smears of fluid from scrapings from the edge of lesions. These smears contain many plasma cells.

Biopsy specimens are taken if the diagnosis is unclear or if adequate tissue fluid cannot be obtained because lesions are dry, sclerotic, or necrotic. The bacteria do not grow on ordinary culture media.

• Antibiotics

Many oral antibiotics kill the bacteria, but tetracyclines, macrolides, and trimethoprim/sulfamethoxazole (TMP/SMX) are most effective, followed by ceftriaxone, aminoglycosides, fluoroquinolones, and chloramphenicol.

The recommended oral regimen is azithromycin 1 g once/week or 500 mg/day for > 3 weeks and continued until all lesions have completely healed (1).

Alternate oral regimens should be continued until all lesions have completely healed and include the following (1):

• Doxycycline 100 mg orally 2 times a day for at least 3 weeks

• Trimethoprim/sulfamethoxazole 1 double-strength (160 mg/800 mg) tablet orally 2 times a day for ≥ 3 weeks

• Erythromycin base 500 mg orally 4 times a day for ≥ 3 weeks

IV or IM antibiotics (eg, ceftriaxone) are an alternative.

Response to treatment should begin within 7 days, but healing of extensive disease may be slow and lesions may recur, requiring longer treatment. Patients with HIV infection may also require prolonged or intensive treatment. After apparently successful treatment, follow-up should continue for 6 months.

Sex partners within 60 days before onset of the patient's symptoms should be examined and, if infected, treated.
