有坏死，细胞核呈空泡状，可见雪茄样核，核分裂易见，是不是还要考虑：

1. 子宫平滑肌肉瘤；2. 富于细胞的平滑肌瘤

有坏死，核分裂易见,细胞异型性不明显，考虑1.平滑肌肉瘤；2.低度恶性倾向平滑肌瘤。

 The key for this case is the types of necrosis, geographic , coagulative tumor necrosis or infartive, hyaline necrosis.

1. no obvious cytologic atypia

2. mitotic rate >15/10hpf

3. type of necrosis?

If it is tumor coagulative necrosis, the case is leiomyosarcoma.

If it is infarctive, hyaline necrosis, the case is STUMP (smooth muscle tumors of uncertain malignant potential).

I favor STUMP.

 Leiomyosarcoma and STUMP can have different prognosis and treatment.

It is not an easy case. Luo zhu needs carefully to review the case and makes your dx.
