Statistics from

Variation in clinical pictures of syphilis, when co-infected with HIV are well known.1 Normally, a classic Hunterian chancre heals within 1–2 weeks of treatment without scarring.2 Primary chancre, healing with perforation of the site, does not commonly occur.3 Here we report four patients with primary syphilis, in whom the chancres healed with perforation of the genitalia. Concomitant infection with HIV is presumed to be responsible for this destructive sequela.


A 21 year old woman presented with a painless, indurated ulcer on the inner aspect of the left labia majora, along with same sided inguinal lymphadenopathy of 1 week’s duration. Dark ground microscopy (DGI) was positive for Treponema pallidum and VDRL titre was 1:64. Following treatment with penicillin, the ulcer healed slowly, leaving a perforation on the labia majora.


A 20 year old unmarried male patient with high risk behaviour presented with a painless indurated ulcer over the dorsal aspect of the prepuce and unilateral inguinal lymphadenopathy. DGI was positive for T pallidum and VDRL titre was 1:32. He had a history of genital ulceration and was treated for suspected lymphogranuloma venereum. Following treatment with penicillin, the ulcer healed at a slower pace leaving a large perforation on the prepuce (fig 1).

Perforation of prepuce.


A 23 year old unmarried man, with a history of repeated unprotected exposure to commercial sex workers, presented with a painless, indurated ulcer on the dorsal prepuce, multiple genital mollusca contagiosa, and genital warts. Bilateral inguinal lymphadenopathy was present. DGI from the ulcer was negative and VDRL was 1:64. Following penicillin therapy, it healed with perforation of the prepuce.


A 45 year old married man with high risk behaviour presented with a large perforation on the lateral side of the shaft of the penis. He gave a history of a painless ulcer on the same site about 1 month earlier. At presentation, his VDRL was 1:32. He was treated with penicillin.


Gram stained smears from the ulcers and culture for aerobic and anaerobic organisms were negative in first three cases. In all the four patients, ELISA for HIV was positive.

Immune response to T pallidum is primarily cell mediated.2 In an immunocompetent host with primary syphilis, CD4+:CD8+ T lymphocyte ratio is high at the site of the chancre,2 which possibly prevents local multiplication of the organism. Consequent to the loss of local cellular immunity as a result of HIV infection there may be an enhanced ability of the organism to multiply locally, giving rise to larger and deeper ulcers which are slower to heal. This fact has been demonstrated experimentally in animal models.4

Studies exploring the correlation of CD4+ T cell count and stage of HIV infection with this altered manifestation of primary syphilis should be undertaken. This might show the impact of HIV infection on the clinical severity of primary chancre.
