Endometrial Stromal Tumors

Endometrial stromal tumors are rare, and endometrial stromal nodule is the least common. In the region of Middle Jutland, Denmark, only two cases are reported since 1995. The nodules are benign; nevertheless, hysterectomy is the treatment of choice. Tumor margins are required for diagnosis and essential to differentiate it from an invasive stromal sarcoma whose prognosis is very different. We report a rare case of a 38-year-old woman, with presurgical diagnosis of a uterine tumor/polyp. She presented with nausea and changes in bleeding pattern and initially had a transcervical polyp resection performed. Histopathological examination showed the presence of an endometrial stromal tumor with unclear margins, and an invasive malignant endometrial sarcoma could not be excluded. Pathological examination revealed an endometrial stromal nodule with invasion, not exceeding three mm. Endometrial stromal tumors are interesting due to their rare existence and difficulties in establishing a histological diagnosis. Although endometrial stromal nodules are benign entities, they must be differentiated from the other invasive malignant stromal tumors, which may change the final prognosis. No preoperative diagnostic tools are at hand, and benign as well as malignant tumors are treated with hysterectomy.

First Case

INTRODUCTION: Primary breast sarcoma (PBS) was first described in 1887 as a rare heterogeneous neoplasm arising from the mesenchymal tissue of the mammary gland accounting for less than 5% of all body soft-tissue sarcomas and less than 0.1% of all malignant tumors of the breast. CASE PRESENTATION: A 31-year old lady presented with left breast mass which she felt four years before during which the mass increased in size from 1 to 6 cm in the largest diameter, diagnosed clinically as a benign fibroadenoma without any further cytological or histopathological confirmation. Histopathological examination of the excised breast mass reveals undifferentiated, primary stromal sarcoma of the breast (PSSB), which was followed by mastectomy three weeks later with reconstructive breast surgery with a total duration of follow-up of 3 years thereafter. This is the first case of PSSB reported in Jordan. DISCUSSION/CONCLUSION: PSSB is the generic term given to malignant breast tumors thought to arise from the specialized mesenchymal stroma of the breast but lacking an epithelial component with a phylloides pattern. PSSB is difficult to diagnose preoperatively due to its rarity and inadequate imaging methods to establish an exact diagnosis. The histology of the patient mass may be the leading factor for the management of these tumors. Even in very young patients, a progressively growing breast mass should alert the clinician to investigate for malignancy and verify the results by biopsy. Surgery with adequate resection margins represents the only potentially curative modality with prognostic significance. Adjuvant chemotherapy and radiotherapy are not very beneficial. The prognosis is dismal for patients with lymph node involvement and the size of the tumor has a lesser bearing on the outcome.

Endometrial Stromal Tumors

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.

Introduction. Leiomyoma is a benign vascular tumor affecting the greater saphenous vein rarely. Proper histopathological examination sets the diagnosis after complete and wide surgical excision along with a normal portion of the GSV.Case Presentation. A 36-year-old woman was admitted to our hospital complaining of a dull ache on her right groin for the last three months, along with a palpable mass on the mentioned area. An ultrasound (U/S) scan revealed a solid mass measuring3×2 cm. After wide surgical excision, pathological examination revealed a leiomyoma of the GSV.Discussion. Benign and mostly malignant tumors arising from the GSV are reported in the literature before. Diagnostic modalities and clinical examination cannot set a correct diagnosis preoperatively due to no specific characteristics of these tumors. Possible sarcomatous behaviour has to be kept in mind when treating tumors arising from a vessel wall and wide surgical excision as negative margins should be attempted.

Endometrial Stromal Tumors

Endometrial stromal tumors are rare uterine malignancies composed of cells resembling those of proliferative endometrial stroma. Because of their indistinct clinical and radiological features, these malignancies are very rarely diagnosed preoperatively. They are mostly often diagnosed as fibroid uteruspreoperatively and as a result managed conservatively many a time. Usually distinguishing these tumors from benign smooth muscle tumors of the uterus are not problematic by light microscopy, however, difficulties arise in distinction between highly cellular leiomyomas and endometrial stromal sarcomas with smooth muscle differentiation. Here we present four consecutive cases of low grade endometrial stromal sarcomaswith emphasis on their clinical, histopathological and immunohistochemical features. By this study, we have attempted to document the histologic features of LGESS with discussion of the differential diagnoses to contribute to this rare spectrum of uterine neoplasms.Journal of Pathology of Nepal (2015) Vol. 5, 774-777

Background : Malignant ovarian tumor are still the number one cause of death and the second most  of incidents for gynecological malignant tumors. The principles of management of ovarian cancer are the same as the principles of handling other malignant diseases, for the treatment of primary lesions operatively and the handling of potential sites of tumor metastases with chemotherapy. Histopathological examination is still considered a gold standard for diagnosis and definitive treatment of malignant ovarian tumors. If histopathologic results are obtained, then the patient will be planned to undergo postoperative chemotherapy. The mismatch between the preoperative and intraoperative clinical features, and the results of postoperative histopathological examination is a problem in managing cases of ovarian malignant tumors.Objective : Report a case of residive ovarian carcinoma with no appearance of malignancy marker in the previous postoperative histopathological examination.Method : Case reportCase : We report the case of a 45-year-old woman with a history of two previous laparotomy. The first operation was carried out in February 2014 on the indication of an extra ovarian cyst, resulting in the impression of a "Follicular Cysts" based on histopathological examination. The second operation was performed in March 2015, performed surgical staging tumors with an indication of malignant ovarian tumors with clinical metastases, but from histopathological examination it was found that "Cystadenoma Ovarii Muscinosum Multiloculare" and "no visible signs of malignancy", so the patient was not managed with postoperative chemotherapy. In April 2019 patients came with complaints of new mass growth, from CT-Scan and USG investigations there was a suspicious impression of a residive ovarian tumor with metastases into the omentum and massive ascites. On May 16, 2019 an optimal debulking was performed with the findings of residive mass, ascites, and mass metastases in the intra operative peritoneum. From the results of histopathological examination, it was found that "Muscinous Carcinoma with metastases to the umbilicus, peritoneum, and ascitic fluidKeywords: Malignant residive ovarian tumor, mucinous ovarian carcinoma

Background: Adnexal mass is a common presentation in today’s gynecological practice. The incidence of ovarian cancer is increasing day by day and diagnosis is often difficult to be made pre operatively with inadequate surgical exploration is a regular occurrence. Aims and Objectives: To assess and validate the importance of RMI-3 score as pre-operative diagnostic tool of differentiating benign from malignant adnexal mass for starting first line therapy of ovarian cancer and to find out the incidences of ovarian malignancy among study population. Material and Methods: The study was conducted in the Department of Gynecology and Obstetrics on (n=115) patients attending GOPD and indoor with adnexal mass fulfilling the inclusion and exclusion criteria using purposive sampling technique. All the selected cases underwent ultrasonography and serum CA- 125 level estimation necessary for calculating RMI score. A score of >200 was taken as suggestive of malignancy and confirmatory diagnosis was performed by histopathological examination obtained from staging laparotomy of adnexal mass. The individual scores were then correlated with final outcomes with statistical analyses. Results: The study revealed benign ovarian tumors are more under 50 years (78.46%) and patients with normal BMI are diagnosed with maximum of malignancy (n = 28). History of tubal ligation carried less risk of malignancy (p<0.0001). Histologically malignant tumors found mostly in 71.4% postmenopausal group whereas 94.1% benign pathology were present in perimenopausal group and there is no association found between parity and histopathology (p=0.058). Bilateral (p=0.013), multilocular (p=0.000) tumors with solid areas (p<0.0001) and thick papillary projections (p<0.0001) had statistically significant association with malignant lesions. RMI score (>200) had more efficacy than serum CA-125 level (>46) in differentiating malignant lesions from benign one in terms of specificity (96% vs 83.87%) and positive predictive value (95% vs 79.17%). Conclusions: RMI-3 score is a simple, reliable and effective tool in differentiating benign from malignant adnexal masses thereby help in quick referral and management of cases with increase chances of survival of the patients.

AbstractFibrosarcomas are malignant tumors of the connective tissue, which are characterized by proliferation of fibroblasts. Most of these tumors are localized subcutaneously and cause different symptoms depending on their location. The case report describes a dermal tumor on the outside of the pinna in a 7-year-old female Cashmere goat. The tumor was surgically removed and histopathological examination revealed a low grade fibrosarcoma. Although tumors are rare in ruminants because of the animals’ short lifespan (age of slaughtering in most cases < 24 months) in modern production processes, they should be considered as a differential diagnosis.

Extragastrointestinal stromal tumors (EGISTs) are rare tumors that arise outside the digestive tract. We report a case of an EGIST arising in the subcutaneous tissue of the abdominal wall, which at this site can often be misdiagnosed as dermatofibrosarcoma protuberans. The tumor was surgically resected from a 72-year-old male Chinese Han patient, and pathological examination revealed spindle-shaped tumor cells with eosinophilic cytoplasm and an oval nucleus. Immunohistochemically, the tumor cells showed strong cytoplasmic positivity for CD34, c-KIT (CD117), and DOG1. Tests for activating mutations of GISTs showed that the tumor cells carried an in-frame deletion (NP_000213.1:p.Lys550_Gln556del) in exon 11 of c-KIT (CD117). Thus, an EGIST should be considered in patients with abdominal subcutaneous tumors with an epithelioid, spindle-shaped, or mixed morphology. Immunohistochemistry of c-KIT (CD117) and DOG1 and genetic testing for activating mutations are recommended to aid in the differential diagnosis of subcutaneous tumors. In short, although EGISTs are rare in the abdominal subcutaneous tissue, pathologists must be aware of their possibility.

Retroperitoneal Schwannoma

Background and Objectives: Retroperitoneal schwannoma is a very rare case of schwannoma which commonly occurs in the other part of the body. However, it is difficult to distinguish schwannoma from other tumors before pathological examination because they do not show specific characteristics on imaging study such as ultrasound, computed tomography (CT), and magnetic resonance image (MRI). Case summary: A 60-year-old male showed a retroperitoneal cystic tumor which is found incidentally during evaluation of coexisted bladder tumor. Neurogenic tumor was suspicious for the retroperitoneal tumor through pre-operative imaging study. Finally, a schwannoma was diagnosed by immunohistochemical examination after complete surgical excision laparoscopically. Conclusion: As imaging technology is developed, there may be more chances to differentiate schwannoma from other neoplasm. However, still surgical resection and histopathological examination is feasible for diagnosis of schwannoma.
