They are lesions that may recur after incomplete surgical enucleation with a variable clinical appearance depending on the clinical form. These clinical variations could be explained by the biological behaviour of the lesion cells which can be explored by the study of the cell proliferation index (Ki67).

These were used to train and validate the developed model. The best ML model achieved a precision of 81.9, recall of 71.9, mean Average Precision (mAP) @ 0.5 of 72.6 and F1-score of 76.5.
