Abstract:
A 42-year-old man presented with painless, left inguinal lymphadenopathy, which was suspicious of malignant lymphoma. Multiple left-sided foci of markedly increased metabolic activity were observed on PET/CT (SUVmax up to 22.3), located at the inguinal, iliac, and para-aortic lymph nodes along with small-sized right inguinal lymphadenopathy. Laboratory tests revealed increased inflammation markers and neutrophilic leukocytosis. Pathological examination from dissected inguinal lymph node was consistent with granulomatous disease. Infection by chlamydia trachomatis was made serologically establishing the diagnosis of lymphogranuloma venereum.
