LYMPHOGRANULOMA VENEREUM (LGV)
LGV is caused by one of the serovars (L1, L2 or L3) of Chlamydia trachomatis. The primary skin lesion may well go unnoticed, and is described as a painless papule, pustule or erosion. These organisms are lymphotropic and, in the secondary phase, the main symptoms of LGV are associated with the lymph nodes. The most common sign is tender inguinal and/or femoral lym-phadenopathy. Buboes may form and there may be chronic ulceration and fistula formation. Acute haemorrhagic proctitis may also occur. Since 2003 a series of outbreaks of LGV have been reported in European cities (HPA, 2005). These have been among men who have sex with men (MSM), and most cases present with proctitis.
