Lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by L1, L2, L3 serovars of C. trachomatis (CT). Since 2003, LGV cases have been increasing in Europe. Aim of this report is to describe the LGV cases diagnosed in the largest STI center in Rome, Italy, from 2000 to 2016. This report shows that two clinically and epidemiologically different series of cases exist, and that, at present, the ano-rectal LGV represents the clinical variant occurring more frequently among men having sex with men (MSM), particularly those HIV-infected.

Case presentation

Ten cases of LGV were observed. Three were diagnosed in 2009 in HIV-negative heterosexuals patients that presented the classical genito-ulcerative form with lymphadenopathy. Seven cases were observed in 2015–2016 in HIV-infected MSM, that presented the rectal variant and L2b serovar infection; 4 of these had been misclassified as a chronic bowel disease.
Chlamydia infection was confirmed by CT-specific PCR (ompA gene nested PCR), followed by sequence analysis to identify the serovar.
All the patients were treated with doxycycline for 3 weeks, obtaining a complete response with healing of both clinical symptoms and dermatological lesions.


Our findings suggest that, in case of persistent rectal symptoms in HIV-infected MSM, LGV should be taken into account and investigated through molecular analyses, in order to achieve a correct diagnosis and management of the patients.
