dysplasia
Medical term for abnormal development of cells, tissues, or organs. Used in clinical contexts.
I had a test for cervical dysplasia.
myelodysplastic syndrome; MDS
fibrodysplasia ossificans progressiva; FOP
Compound of 異 (i, 'abnormal') + 形成 (keisei, 'formation'). A medical term likely calqued from Western medical terminology.
