| • | AKA Lymphogranuloma inguinale (vs. granuloma inguinale makes it easy to remember) |  
 | • | mainly a disease of lymphatic tissue that spreads to tissue surrounding lymphatics |  
 | • | Chlamydia trachomatis: 15 serotypes, only 3 cause LGV L1, L2, L3  |  
 | • | primary lesion: small painless erosion that heals without scarring (patient will often not notice or remember it; and resolves before nodes enlarge) |  
   
secondary lesion: lymphadenopathy (= main clinical presentation) 
| • | 1-4 weeks after primary lesion heals |  
 | • | unilateral 2/3 of time;  painful; 1/3 rupture |  
 | • | buboes =  inflammatory swelling of lymph nodes  |  
 | • | groove sign:  enlargement of inguinal nodes above, and femoral nodes below, Poupart’s ligament;  1/5 of patients;  pathognomonic |  
   
diagnosis: 
| • | culture available but recovery rate <50% |  
 | • | serologic tests non-specific |  
 | • | therefore, treat with doxycycline |  
   
summary: 
| • | rarely see primary genital ulcer |  
 | • | presents as lymphadenopathy |  
 | • | females get rectal strictures (because disease affects internal lymphatic drainage) |
