Primary ovarian leiomyoma in a premenarchal adolescent: first reported case

Case Report: Primary Ovarian Leiomyoma: A Clinical Analysis of Case Series and Literature Review

Ovarian leiomyoma accounts only for 0.5–1% of all benign ovarian tumors, and almost no preoperative diagnosis has been achieved. Commonly, these tumors are small in size and asymptomatic. However, they can become symptomatic as their size increases; thus, it is important to recognize this entity and differentiate them from ovarian malignant tumors. Radical surgeries with total hysterectomy and salpingo-oophorectomy are usually performed. However, ovary-preserving surgery has been suggested to young women, especially those desiring fertility in the future. In this study, we shared seven cases of primary ovarian leiomyomas and one inherent ligament leiomyoma, reviewed related articles to provide some new information about leiomyoma of the ovary, and discussed their proper surgical management.

Primary Ovarian Leiomyoma Associated with Multiple Uterine Leiomyomas

Ovarian leiomyomas are very rare. We report the case of a primary ovarian leiomyoma accompanied by multiple uterine leiomyomas. A 50-year-old woman was referred to our department for heavy menstruation, and a hot spot in the uterine lumen was observed on positron emission tomography-computed tomography (PET-CT). Cervical and endometrial cytology and tumor marker tests were negative. Pelvic magnetic resonance imaging revealed an endometrial polyp and submucosal leiomyoma in the uterine lumen and a 5-cm right ovarian tumor. Laparoscopic total hysterectomy, right salpingo-oophorectomy, and left salpingectomy were performed for radical treatment. Histopathology showed that ovarian tumors contained interlacing bundles of fusiform cells encircled by normal ovarian tissue. Immunohistochemical staining showed strong and diffuse positive staining for α-smooth muscle actin. We diagnosed the tumor as a primary ovarian leiomyoma because the leiomyoma was localized in the ovary and was larger than the size of uterine leiomyomas. No metastatic lesion was found on PET-CT. There was no tumor recurrence at the 6-month follow-up.

Bilateral ovarian edema with unilateral ovarian leiomyoma and double inferior vena cava: a case report

Background

Ovarian edema, ovarian leiomyoma, and double inferior vena cava are all rare clinical entities. The coexistence of all these entities has not been yet reported in the literature.

Case presentation

We report a case of a 25-year-old nulliparous tamang woman with all these rare clinical entities, who presented with a complaint of right-sided lower abdominal pain. After examination and investigation, an ovarian tumor was suspected and laparotomy was performed during which bilateral ovarian edema with a solid tumor on the left side was identified and left salpingo-oophorectomy was done preserving her right ovary. A histopathological examination confirmed the clinical findings.

Conclusions

As ovarian edema is a rare entity, due to lack of clinical suspicion it is often overdiagnosed as a malignant tumor leading to radical surgery with subsequent loss of hormonal function and early infertility. A high degree of clinical suspicion during the intraoperative period is helpful for diagnosis to avoid unnecessary oophorectomy and infertility.

One case report of giant atypical leiomyoma of the ovary

RATIONALE

Ovarian leiomyoma is a rare ovarian tumor that occurs in 20-65 year-old women, and is mostly misdiagnosed as malignant tumor. In most reports on this type of tumor, ovarian myoma has a benign histology. Herein,we describe a case of ovarian atypical leiomyoma.

PATIENT CONCERNS

The patient is a 58-year-old woman. At the age of 40 years old, the patient underwent hysterectomy due to "hysteromyoma" and secondary anemia. The patient was admitted to our hospital due to palpation of lower abdominal mass and abdominal distention.

DIAGNOSES

A mass was revealed at the left uterine appendage by pelvic ultrasound and CT.Pathology and immunohistochemistry confirmed the diagnosis of the left ovarian atypical leiomyoma.

INTERVENTIONS

Pelvic cavity resection and right adnexectomy were performed during laparotomy for the patient.

OUTCOMES

Without radiotherapy or chemotherapy, there were no signs of tumor recurrence in a 9-month follow-up period.

LESSONS

When a solid mass appears in ovarian tissues, ovarian leiomyoma should be considered. Patients with this type of tumor are mostly asymptomatic. Preoperative diagnosis was difficult, intraoperative frozen section would be helpful for determining the scope of the surgery, and the correct diagnosis was made by identifying the properties of smooth muscles through postoperative pathology and immunohistochemistry.

Primary ovarian leiomyoma in a postmenopausal woman: A case report

Leiomyomas are benign neoplasms that can develop wherever smooth muscle is present. Primary leiomyomas of the ovary originate from smooth muscle cells of ovarian tissue and are rare, solitary tumors. Approximately 70 cases have been reported. They usually present in premenopausal women. The present case is a report of left ovarian leiomyoma in a postmenopausal woman.

Primary ovarian leiomyoma: A case report

•

Primary ovarian leiomyoma is one of the rarest solid tumours of the ovary.

•

Many patients with ovarian leiomyomas are nulligravidas.

•

Differential diagnosis can be difficult from ovarian solid tumours.

•

The diffuse strong positive staining for SMA is characteristic of leiomyoma.

•

Unilateral and benign tumours can be treated with unilateral salpingo-oopherectomy.

INTRODUCTION

Primary ovarian leiomyoma is a rare benign tumour of the ovary seen in women between 20 and 65 years old. It is usually diagnosed incidentally during pelvic examination or pathologic examination after surgery.

PRESENTATION OF CASE

We describe a case of unilateral, ovarian leiomyoma. Transvaginal ultrasonography and magnetic resonance imaging (MRI) revealed a right adnexial mass. Unilateral salpingo-oophorectomy was performed, and histological examination revealed a leiomyoma arising primarily in the ovary. The diagnosis was confirmed immunohistochemically.

DISCUSSION

The tumour may be asymptomatic or may manifest with lower abdominal pain like in our case. The definitive diagnosis of these lesions is difficult prior to surgical removal. Because there is no pathognomonic symptoms or characteristic imaging findings. The correct diagnosis of an ovarian leiomyoma requires identification of the smooth muscle nature of the tumour.

CONCLUSION

This rare tumour of the ovary should be considered in the differential diagnosis of solid ovarian masses. An immunohistochemical analysis is recommended for definitive diagnosis.
