Abstract
Malignant External Otitis (MEO) usually occurring in middle aged or elderly diabetics is uncommonly seen in children and rarely in infants. Various studies done so far have proved that immunological disturbance is present in case of MEO, Eliashiv et al (1978) and Yust et al (1980) have proved that cell mediated immunity is depressed in cases of MEO occurring in diabetics. MEO occurring in a four month old grosslly immunadeficient infant is indeed a very rare presentation. Occurrence of MEO in immttuo-suppressed children, & in cases of AIDS, and conclusions of various immunological studies along with this presentaion emphasize the need of regular immuological work up in all cases of MEO.
