The diagnosis of gastrointestinal (GI) mucormycosis is always a challenge due to its non-specific clinical presentations and often diagnosed at autopsy. Recently increased number of GI mucormycosis has been reported in immunocompetent hosts and during 1948 through 2017, 200 cases of GI mucormycosis are available in literature. We could review 176 cases where case details were available. Majority (50.6%) of the cases were reported from Asia. The disease is nearly equally recorded in adults and paediatric population. The infection commonly affected the intestine (64.2%) followed by stomach (33%). A significant improvement in antemortem diagnosis was noted since 2001. Rhizopus species were the predominant (67.5%) aetiological agents. Amphotericin B was the most commonly used drug (93.4%). Despite improvement of antemortem diagnosis and therapy, the mortality was 60.5% and 67.5% in adults and children respectively. Combined medical and surgical therapy (reported in 47.8% patients) had significantly better survival rate than those receiving either of them. Analysing the clinical presentations, we propose to suspect GI mucormycosis in a malnourished/ dehydrated child (especially premature neonate) with history of exposure to broad-spectrum antibiotics or formula/spoon feeding and presenting with mass in abdomen, abdominal distension or bilious vomiting; and an adult presenting with abdominal distension, fever or GI bleed with underlying risk factors for mucormycosis.
