Pathology, Research and Practice Apr 2024Ovarian fibromas are benign tumors that can present peculiar morphological features not studied sufficiently.
BACKGROUND
Ovarian fibromas are benign tumors that can present peculiar morphological features not studied sufficiently.
MATERIAL AND METHODS
In this retrospective study, 75 consecutive cases of ovarian fibroma were morphologically compared with 46 thecomas, 16 granulosa cell tumors, and 5 sclerosing stroma tumors for the following factors: the growth pattern as diffuse or nodular, the presence of hyaline plaques, necrosis, keloid-like sclerosis, calcifications, cystic degeneration, fibrous or edematous stroma, prominent vascularity, lutein cells, cellularity, scant or abundant cytoplasm, prominent cell membranes, nuclear grooves, atypia, and mitotic activity.
RESULTS
The tumors differed significantly in terms of hyaline plaques presence, nuclear grooves, growth pattern, stroma type, tumor cellularity, cytoplasm, prominence of cell membranes, atypia, mitotic activity, and prominent vascularity.
CONCLUSION
Ovarian fibromas can present some maybe unexpected features rather frequently, such as cystic degeneration, hyaline plaques, prominent vascularity, increased cellularity, and some mitotic activity, thus their presence should not always prompt to an alternative diagnosis.

In medicine, Meigs' syndrome is the triad of ascites, pleural effusion, and benign ovarian tumor (fibroma, Brenner tumour, and occasionally granulosa cell tumour). It resolves after the resection of the tumor. Because the transdiaphragmatic lymphatic channels are larger in diameter on the right, the pleural effusion is classically on the right side. The etiologies of the ascites and pleural effusion are poorly understood. Atypical Meigs' syndrome,characterized by a benign pelvic mass with right-sided pleural effusion but without ascites, can also occur. As in Meigs syndrome, pleural effusion resolves after removal of the pelvic mass. The authors would like to share their own experience of a case of Meigs' syndrome associated with an enormous ovarian fibroma and elevated Ca-125.

Ovarian fibroma with minor sex cord element (MSCE) is a rare tumor. The increased estrogen production due to the presence of MSCE and/or luteinized thecal cells within fibroma can be a risk factor for endometrial hyperplasia or carcinoma.

Cellular fibromas represent ~10% of ovarian fibromas. Mitotically active cellular fibromas show mild nuclear atypia but ≥4 mitoses/10 high-power fields: the clinical course is usually uneventful but literature review is lacking. A 34-yr-old woman underwent left oophorectomy for a 9-cm ovarian mitotically active cellular fibroma at another hospital. The tumor was cellular (spindle cells in fascicular and storiform patterns) revealing mild atypia and 4 nonatypical mitoses/10 high-power fields without necrotic areas. After 16 yr, the tumor recurred as a 5-cm peritoneal nodule on the anterior sigmoid wall near the sigmoid-rectal junction. Frozen section revealed a spindle cell tumor invading the intestinal tunica muscularis propria: a gastrointestinal stromal tumor was favored as previous history was unavailable at that time. Intestinal resection was performed: no residual tumor was found. The patient was followed-up for 8 yr without further recurrences. The peritoneal nodule showed 2 mitoses/10 high-power fields and pericellular reticulin staining. The tumor was variably positive for vimentin/bcl-2/melan-A/CD56/ER/PR/α-inhibin/CD10/calretinin, focally positive for desmin, negative for pan-cytokeratin/actin/EMA/CD34/HMB45/CD117/CD99/S100/synaptophysin. The Ki67-index was ~9%. To our systematic literature review, 7 additional recurrent cases were reported. We describe a mitotically active cellular fibroma recurring after the longest interval of time. Extensive sampling of difficult cases should exclude malignant areas. Moderate nuclear atypia, tumor rupture, adhesions to pelvic/abdominal organs, infarction with extraovarian involvement, and incomplete excision may lead to relapse but there are conflicting data: prolonged follow-up can be suggested in these cases.

Computed tomography obtained as part of a urinary tract assessment in a 68-year-old woman incidentally detected a solid adnexal mass. Bilateral salpingo-oophorectomy revealed a unilateral, 4-cm, white to tan-yellow colored, focally calcified, left ovarian mass. Microscopically, the tumor was composed of bland fibroblasts, abundant collagen, and areas of calcification with a minor component composed of nests of epithelial cells with nuclear clefts focally evident, some of which contained central lumens with eosinophilic secretions. The major considerations were fibromatous overgrowth in a Brenner tumor or ovarian fibroma with minor sex cord elements. Immunostains for cytokeratin 7 showed diffuse positivity in the epithelial nests, whereas cytokeratin 20 and inhibin were negative, further supporting the diagnosis of a Brenner tumor.

We report the case of a 55-year-old patient who pre- sented a pelvic mass, ascites and elevated serum CA125. Suspecting a malignant process she underwent surgery and a total hysterectomy with bilateral salpigo-oforectomy was performed. Pathologic report revealed a bilateral ovarian fibroma and non-tumoral ascites. The presence of elevated serum CA125 levels in a postmenopausal woman with a pelvic mass and ascites suggest an ovarian malignant disease. However, in case of Meigs'syndrome, all symptoms will diappear after removal of the pelvic tumor, so a fast surgical management of the patients is mandatory.
