Difficult diagnosis of invasive fungal infection predominantly involving the lower gastrointestinal tract in acute lymphoblastic leukaemia

Invasive fungal infections are most commonly seen in immunocompromised patients and usually affect the respiratory system. Gastrointestinal system involvement of mucormycosis and invasive aspergillosis is rarely reported in childhood. Here we describe a 5 year old boy with acute lymphoblastic leukaemia who developed invasive fungal infection particularly affecting the lower gastrointestinal system to emphasise the difficulties in diagnosis and management of invasive fungal infections in immunocompromised patients.
