A 15-year-old boy was admitted with the diagnosis of colonic polyposis, and 
during a 2-year follow-up, he underwent operation for right parieto-occipital 
anaplastic astrocytoma, left-side colonic non-Hodgkin lymphoma (NHL) and 
cerebella glioblastoma which were all confirmed by histology. Although cases of 
Turcot's syndrome (TS) (colonic polyposis and primary brain tumour occurring in 
the same patient) have been previously described, association with 
haematological malignancy is rare. We hereby report such a case with TS.
