Granuloma inguinale (donovanosis) presenting as a neck mass in an infant.

A case of granuloma inguinale (GI) presenting as a lateral neck mass in a 4-month-old, HIV-positive infant is described. The histological features of the mass were typical of GI, with numerous macrophages containing intracellular organisms with a "closed-safety-pin" appearance. This is a rare occurrence, and the mode of transmission of infection is discussed. An awareness of GI in infants by both clinicians and pathologists is important to prevent morbidity and allow for prompt institution of appropriate treatment.
