Among the different hysteroscopic patterns that have been described to assess endometrial cancer, it seems especially interesting the one developed by Dr F. Coloma. This classification describes three hysteroscopic patterns:
·Pseudohyperplastic pattern: Individualized aspect of multiple buds with sharp edges and atypical vascularization.
·Nodular pattern: Fixed nodule with solid aspect and a wide base with atypical poor vascularization.
·Malignant polyp: A polyp with signs of malignancy that affects the entire polyp or fragments of it.
These three patterns have an advanced sub-pattern, in which tissue breakdown, necrotic areas and fibrin deposits are appreciated
