Thanks for your question on HCM. Dysplasia is pathological term and related to morphology of cells seen under microscope. And it is used for all cells of the body. Dysplasia means abnormal cells in morphology. Most common is malignant cells. So any cell with malignant potential show certain morphological changes like high N-C ratio (nucleo cytoplasmic ratio) , granular cytoplasm etc. This termed as dysplastic cell (likely to malignant). So presence of dysplasia means high probability of malignancy. And absence of dysplasia (as in your report) means less probability of malignancy. So no need to worry. Your report is good. Get done follow up after 10-12 months.
