Abstract

Constitutional mismatch repair deficiency (CMMRD) syndrome is characterised by a significantly increased risk for developing cancer in childhood. It arises when both parents have a mutation in the same mismatch repair gene and pass it on to their child. Case description An 8yearold girl was diagnosed with CMMRD syndrome after she developed a brain tumour at the age of 4 and a Tcell nonHodgkin lymphoma at the age of 6. She had multiple hyperpigmented skin lesions and died of myelodysplastic syndrome at the age of 11. Conclusion In children with cancer CMMRD syndrome can be recognized particularly if there are multiple primary malignancies and skin hyperpigmentations and hypopigmentations. The parents of these children are at high risk for colorectal and endometrial cancer (Lynch syndrome), amongst others.
