Endometrial Stromal Nodule: A Case Report
The endometrial stromal nodule (ESN) is the rarest subtype of endometrial stromal tumors (ESTs) that's why experience with Endometrial Stromal Nodule is limited. Endometrial Stromal Nodule could mimic highly cellular leiomyomas, usually seen in the premenopausal age. Patients present with non-speci?c symptoms such as abnormal bleeding, lower abdominal pain, or maybe asymptomatic. Our patient was 46 years old woman suffering from abnormal uterine bleeding and lower abdominal pain and had no desire to protect fertility. The preoperative diagnosis of Endometrial Stromal Nodule is very difficult. Also, no speci?c imaging is de?ned for the Endometrial Stromal Nodule in ultrasound or MRI examination. Endometrial Stromal Nodule is usually misdiagnosed as uterine ?broids, interstitial ectopic pregnancy, or stromal hyperplasia. Macroscopically, these tumors are classically well-circumscribed, solitary, encapsulated. In a curettage specimen, the distinction between an Endometrial Stromal Nodule and a low-grade endometrial stromal sarcoma is almost impossible, unless the tumor is too small, and the margins can be fully evaluated. In conclusion, Endometrial Stromal Nodule is a rare subtype of endometrial stromal sarcomas, but there is nothing to afraid of if you do the hysterectomy. So, it is important to diagnose preoperatively especially in young nulliparous women who desire to preserve fertility. Clinical presentation is non-speci?c and there is no preoperative imaging that can completely rule out malignancy. It is necessary to develop new diagnostic methods or new treatment options to protect the uterus.
