A large ovarian steroid cell tumor-not otherwise specified with a unique combination of benign and malignant features as a challenging cause of oligomenorrhea and hirsutism in a 21-year-old Syrian female: a case report

Giant Ovarian Tumors in Young Women: Diagnostic and Treatment Challenges-A Report of Two Cases and Narrative Review of the Recent Literature

Background: Ovarian cysts (OCs) are a common gynecological issue, with approximately 20% of women developing at least one pelvic mass during their lifetime. The incidence of large ovarian cysts has decreased substantially due to regular gynecological screenings. However, giant ovarian tumors still continue to pose significant diagnostic and therapeutic challenges. Methods: We report two cases of giant ovarian tumors (GOTs). Case 1 involves a 17-year-old woman who presented with a 2-year history of gradual abdominal enlargement, accompanied by repeated attempts at weight reduction. A computed tomography (CT) scan revealed a large tumor. It was excised by laparotomy. Histopathologic examination revealed ovarian cystadenofibroma. Case 2 presents a 25-year-old female who had a 3-month history of progressive, severe abdominal distension and weight gain, accompanied by nausea and diarrhea. CT imaging revealed a giant cystic neoplasm. The cyst was removed by laparotomy. The histopathological study revealed the intestinal-endocervical mucinous borderline tumor. In this context, we performed a narrative literature review, including cases of giant ovarian tumors in young women over the past five years. We centered on diagnoses and management in these cases. Results: The surgical management of both cases was successful, with complete tumor excision and favorable postoperative outcomes. hese cases underscore the importance of including giant ovarian tumors in the differential diagnosis of young women presenting with progressive abdominal distension. The narrative review analyzed 39 relevant publications on the management of giant ovarian tumors in young women. Conclusions: It is important to highlight a possible risk of malignancy, and risk of fatal complications during the surgical removal of giant ovarian cysts (GOCs). To ensure safer and more successful outcomes, multidisciplinary care should be provided. The early detection and diagnosis of OCs are challenging, as patients may not seek medical attention until the tumor has become large enough to cause symptoms. It is crucial to raise awareness among family doctors and other primary care providers (PCPs) regarding OCs to ensure optimal diagnostic and therapeutic management and improve the outcomes for patients with OCs.

Ovarian steroid cell tumors, not otherwise specified: three case reports and literature review

Objective

To provide a reference for the diagnosis and treatment of ovarian steroid cell tumors, not otherwise specified (SCTs-NOS).

Methods

We retrospectively analyzed the clinicopathological data of three patients with SCTs-NOS admitted to the Tianjin Medical University General Hospital from 2012 to 2022 and reviewed literature reports related to this disease.

Results

A total of 3 cases in our center and 70 cases searched in literature reports were included. The age at diagnosis ranged from 3 to 93 years (median, 34 years). The common clinical manifestations were hirsutism, acne, deepened voice, clitoromegaly, amenorrhea, and excessive weight gain. Tumor sizes ranged from 1.2 to 45 cm, with an average diameter of 6.5cm. Most of SCTs-NOS were benign, but some of them exhibited malignant behavior. Surgery was the main treatment and close follow-up was required. The follow up time of 73 cases ranged from 3 to 132 months (median, 21.3 months). Disease recurrence or progression occurred in 14 cases (19.2%). Three of the 73 patients had a successful pregnancy.

Conclusion

SCTs-NOS usually occur in women of reproductive age, which are mainly manifested as androgen excess symptoms. Surgery is an appropriate treatment for SCTs-NOS and should be individualized. Final diagnosis depends on pathology. SCTs-NOS have malignant potential, and the treatments for patients with malignant tumors and disease recurrence or progression were cytoreductive surgery, adjuvant chemotherapy, and gonadotrophin-releasing hormone agonists (GnRHa) therapy.

Ovarian mass in a patient with invasive breast carcinoma: A case report of an unexpected diagnosis

INTRODUCTION

Ovarian steroid cell tumors not otherwise specified (OSCT-NOS) are extremely rare ovarian sex cord stromal tumors, accounting for <0.1 % of all ovarian tumors. In 25 % of cases, they are asymptomatic leading to a delay in diagnosis. We, herein, report a singular case of OSCT-NOS diagnosed incidentally during the spread assessment of an invasive breast carcinoma of no special type (IBC-NOS). To the best of our knowledge, this is the first reported case of co-occurrence of OSCT-NOS and IBC-NOS. We aim to study the clinic-pathological characteristics of this rare tumor.

CASE PRESENTATION

A 56-years old postmenopausal female, with no previous medical history, was diagnosed with an invasive IBC-NOS. The tomography performed during the spread assessment of IBC-NOS showed a suspicious mass of the right ovary. Pelvic MRI revealed an ovarian solid T1 isointense and T2 hyperintense mass. The first evoked diagnosis was an ovarian metastasis of the IBC-NOS. The patient underwent bilateral salpingo-oophorectomy. On gross examination, an ovarian solid mass measuring 2,5x2cm, with a firm gray yellowish cut surface was noted. Microscopic examination and immunostaining concluded to OSCT-NOS and ruled out the diagnosis of an ovarian metastasis of IBC-NOS.

CONCLUSION

OSCT-NOS are rare neoplasms. Their diagnosis might be challenging especially in absence of hormonal symptoms. A better knowledge of this rare entities would enable early diagnosis.

Hirsutism as the initial presentation of malignant ovarian Leydig cell tumor: A case report

Ovarian steroid cell tumors are a rare subtype of sex-cord stromal cell tumors. Overall, these tumors make <0.1% of all ovarian tumors. These neoplasms can be divided according to the cell of origin into stromal luteomas, Leydig cell tumors, and steroid cell tumors not otherwise specified. These tumors can be benign, malignant, or borderline, with variable presentation. We report a case of 24-year-old virgin female who was referred to our hospital after being diagnosed with steroid cell tumor-not otherwise specified. Prior to her admission, the patient had been treated unsuccessfully with oral contraceptive pills due to male-pattern facial hair growth, abdominal cramps, and irregular menstrual cycle. Lack of improvement warranted further investigations. Hormonal studies showed an elevated total testosterone, dehydroepiandrosterone sulfate, and morning fasting cortisol. Ultrasonography and computed tomography confirmed the presence of a large pelvic mass with mixed solid and cystic component. Therefore, unilateral salpingo-oophorectomy was performed. Pathological and immunohistochemical examination suggested the presence of a large ovarian steroid cell tumor-not otherwise specified with malignant behavior. The patient did not receive adjuvant therapy and developed metastatic disease. She received four cycles of BEP protocol with no improvement, so she was referred to our center to continue oncological management. Case revision confirmed the presence of steroid cell tumor, but of a different subtype: Leydig cell. She received six cycles of carboplatin-paclitaxel, but her assessment showed disease progression. We report this case with review of literature regarding the appropriate approach to these rare tumors. Although rare, ovarian steroid cell tumors should be included in the differential diagnosis of virilization in young females, especially those refractory to hormonal therapy. In our study, we aimed to present the first reported Palestinian case, which highlights the importance of detailed morphological examination in addition to the difficulties encountered to reach a proper diagnosis. We also provided a review of the existing literature regarding chemotherapeutic lines used in such cases and the response to each.

Contrast‑enhanced ultrasound of ovarian steroid cell tumor, not otherwise specified: A case report

Ovarian steroid cell tumor is a rare type of ovarian tumor, accounting for ~0.1% of all neoplasms of the ovary. Patients suffering from this type of tumor exhibit virilization due to high testosterone levels. The present study reported a case of an elderly female patient with high testosterone serum levels, resulting in hirsutism and deepening of the voice. Magnetic resonance imaging did not reveal any solid ovarian tumor. However, gray-scale ultrasound indicated suspicious solid nodules on the right ovary. A clear outline of the tumor, characterized by ring-shaped uniform enhancement, was revealed by contrast-enhanced ultrasound (CEUS) scanning. In addition, laparoscopic resection of both fallopian tubes and ovaries confirmed the right ovarian steroid cell tumor. After the operation, the patient's symptoms were completely relieved and testosterone levels returned to normal. In the present study, a case of ovarian steroid tumor diagnosed by CEUS was reported, supporting the significant role of CEUS in the detection of adnexal tumors.

Cytologic features of sex cord-stromal tumors in women

BACKGROUND

Gynecologic sex cord-stromal tumors (SCSTs) arise from sex cords of the embryonic gonad and may display malignant behavior. We describe the cytomorphologic features of SCSTs in females, including adult and juvenile granulosa cell tumors (AGCTs and JGCTs), Sertoli-Leydig cell tumors (SLCTs), and steroid cell tumors (SCTs).

METHODS

We retrieved available cytology slides from females with a histologic diagnosis of sex cord-stromal tumor between 2009 and 2020 from institutional archives and reviewed their cytoarchitectural features.

RESULTS

There were 25, 2, 2, and 1 cytology specimens from 19, 2, 2, and 1 patients (aged 7-90 years, median 57 years) with AGCT, JGCT, SLCT, and SCT, respectively. Features common to all SCSTs included 3-dimensional groups, rosettes, rare papillary fragments, abundant single cells and naked nuclei. Rosettes and a streaming appearance of cell groups were only seen in AGCTs, which also rarely featured eosinophilic hyaline globules and metachromatic stroma. AGCTs exhibited high nuclear:cytoplasmic (N:C) ratios, with mild nuclear pleomorphism, uniform nuclei with finely granular chromatin, nuclear grooves and small nucleoli; in contrast, other SCSTs lacked rosettes and nuclear grooves and had generally lower N:C ratios, greater nuclear pleomorphism, coarse chromatin and more abundant cytoplasm. Mitotic figures, necrosis, and inflammation were rarely identified.

CONCLUSIONS

AGCTs show cytomorphologic features that are distinct from those of other SCSTs. Careful evaluation of the cytological features and ancillary studies (eg, immunochemistry for FOXL2, inhibin and calretinin, or sequencing for FOXL2 mutations) can aid in the accurate diagnosis of these tumors.
