Endometrial Stromal Nodule: Report of a Case

Abstract

Endometrial stromal nodule (ESN) is the least common of the endometrial stromal tumors. They are rare neoplasms which are diagnosed in most instances by light microscopy. Although such nodules are benign, hysterectomy has been considered the treatment of choice to determine the margins of the tumor required for diagnosis and to differentiate it from invasive stromal sarcoma Whose prognosis is totally different. We report a case of a 45 years old woman, with presurgical diagnosis of adnexal mass or uterine tumor. She underwent a total abdominal hysterectomy. Pathologic examination revealed an endometrial stromal nodule. Through this observation, we insist on the fact that the ESNs are rare and benign entities which must be differentiated from the other invasive malignant stromal tumors; this can change the final prognosis.

Magnetic resonance imaging of an endometrial stromal nodule

“…If present, infiltration generally appears as 1‐3mm sized protrusions . Several reports have described the pathological features of endometrial stromal nodules . However, the characteristic magnetic resonance (MR) imaging appearance of this rare tumor type has not been established; therefore, it is difficult to make a preoperative diagnosis.…”

CD56 might be a useful diagnostic marker of müllerian-derived tumors: report of an uterine tumor resembling ovarian sex cord tumor (UTROSCT) suggesting polyphenotypic origin and review of the literature

“…The behavior of the ESTSCLE is that of the corresponding stromal neoplasm, either endometrial stromal nodule or endometrial stromal sarcoma. Although the behavior of UTROSCT is benign, these tumors are generally considered tumors of low malignant potential with a small risk of local recurrence or metastasis [9,[14][15][16]. The treatment of choice is hysterectomy with bilateral salpingooophorectomy.…”

Endometrial Stromal Nodule: A Case Report

“…As in this case, the biopsy may be negative when the tumor is not associated with the endometrium. The Introduction Endometrial stromal tumors (ESTs) are very rare mesenchyme tumors, and the endometrial stromal nodule (ESN) is the least common [1]. 2014 WHO classificaity showing starburst morphology was observed in the focal areas (Figure 6).…”
