Overview
The clinical manifestation of LGV depends on the site of entry of the infectious organism (the sex contact site) and the stage of disease progression. Inoculation at the mucous lining of external sex organs (penis and vagina) can lead to the inguinal syndrome named after the formation of buboes or abscesses in the groin (inguinal) region where draining lymph nodes are located. The rectal syndrome arises if the infection takes place via the rectal mucosa (through anal sex) and is mainly characterized by proctocolitis symptoms. The pharyngeal syndrome is rare, starts after infection of pharyngeal tissue and buboes in the neck region can occur.
Signs and symptoms
Primary stage
LGV may begin as a self-limited painless genital ulcer that occurs at the contact site 3-12 days or longer in this primary stage. Rarely do women notice a primary infection, because the initial ulceration where the organism penetrates the mucosal layer are located out of sight in the vaginal wall. Also in men fewer than 1/3 of those infected notice the first signs of LGV. This primary stage heals in a few days. Erythema nodosum occurs in 10% of cases.
Secondary stage
The secondary stage occurs from 10-30 days later most often, but has occurred up to 6 months later. The infection is then spread to the lymph nodes through lymphatic drainage pathways. The most frequent presenting clinical manifestation of LGV among males whose primary exposure was genital is unilateral, in 2/3 of cases, lymphadenitis and lymphangitis, often tender inguinal and/or femoral lymphadenopathy because of the drainage pathway for their likely infected areas. Lymphangitis of the dorsal penis may also occur and resembles string or cord. If the route was anal sex the infected person may experience lymphadenitis and lymphangitis noted above or may have proctitis, inflammation limited to the rectum (the distal 10--12 cm) that may be associated with anorectal pain, tenesmus, or rectal discharge, or proctocolitis, inflammation of the colonic mucosa extending to 12 cm above the anus and is associated with symptoms of proctitis plus diarrhea or abdominal cramps and or inflammatory involvement of perirectal or perianal lymphatic tissues. In females cervicitis, perimetritis, or salpingitis may occur as well as the lymphangitis and lymphadenitis in deeper nodes. Because of lymphatic drainage pathways, some end up with an abdominal mass which seldom suppurates and only 20-30% end up with inguinal lymphadenopathy. Systemic signs: fever, decreased appetite, and malaise, may occur as well. Diagnosis is more difficult in women and homosexual men who may not have the inguinal symptoms.
Over the course of the disease, lymph nodes enlarge, enlarged nodes are called buboes, and become painful at first (which may occur in any infection of the same areas as well). The next most common thing is inflammation, thinning and fixation of the overlying skin. Lastly in the progression are necrosis, fluctuant and suppurative lymph nodes, abscesses, fistulas, strictures, and sinus tracts all may occur. During the infection and when it subsides and healing takes place, fibrosis may occur. This can result in varying degrees of lymphatic obstruction, chronic edema, and strictures. These late stages characterised by fibrosis and edema are also known as the third stage of LGV and are mainly permanent.
