Based on the cellularity and increased mitosis, it is a sarcoma. STUMP is one of the differential diagnoses. I do not know if the case has bizarre mitoses, bizarre mitosis will warrant a diagnosis of stromal sarcoma. Both STUMP and stromal sarcoma can have the overall glandular growth pattern. Stromal sarcoma may also have hypercellular stroma surrounding normal glands like STUP. Both STUMP and stromal sarcoma have a positive stain for CD34, which is good for differentiating from other spindle lesion such as leiomyosarcoma, rhabdomyosarcoma. STUMP and stromal sarcoma characteristically express PR and uncommonly EP.
Regarding management stromal sarcoma needs a surgical excision. STUMP is based on age. Older patient can be closely followed up if the lesion does not grow fast. Young patient should have surgery.
