Rectal lymphogranuloma venereum in a bisexual patient.

Rectal Lymphogranuloma venereum (LGV) due to Chlamydia trachomatis (Ct) serotype L2 is reported. LGV was isolated from the lymph node biopsy of a bisexual male and was cultured on McCoy cycloheximide treated-cells. Serological tests such as the Micro-immunofluorescent test and the indirect immunoperoxidase assay for Chlamydia trachomatis done on the patient's serum were positive with a titer of 1/200 and 1/256 respectively. Smears taken from the rectal discharge were stained by the direct immunoperoxidase assay and showed inclusion bodies with positive staining. The search for the origin source of infection as well as the diagnostic and follow-up strategy in the male and female partners is also discussed.
