Collision Tumors

Collision tumor is defined as the coexistence of two or more Histologically distinct tumors adjacent to each other in the same organ without any histological intermixing. Although collision tumors can occur in many organs in the body, its occurrence in ovary is extremely rare. In our series of two patients, dermoid cyst was co-existing with borderline epithelial ovarian tumors in one patient, which is rarest of rare variety of collision tumors reported in ovary. In another patient, there was recurrence in the form of invasive epithelial ovarian malignancy. JMS 2018;21(1):37-39

“Collision tumor” is an uncommon phenomenon characterized by coexistence of two completely distinct and independent tumors at the same site. Collision tumors have been reported in different sites in the body; however, these are particularly uncommon in the pelvic cavity. A 70-year-old man, with prior history of urothelial and prostate cancer, presented with a large pelvic mass detected on imaging studies. Pathological examination revealed a large liposarcoma with prostatic carcinoma embedded in it. Immunohistochemistry and florescence in situ hybridization studies were performed to reach to a conclusive diagnosis. To the best of our knowledge, this is the second case reported till date. We present the challenges encountered in the diagnosis of this case and review of pelvic collision tumors.

Histologically distinct tumors that coexist in an organ without any histological admixture at their interface are denominated collision tumors. We report 3 cases of colliding mature cystic teratoma with mucinous cystadenoma and a case of mature cystic teratoma colliding with benign Brenner tumor in the ovary. We also provide a literature review based on 35 previously published ovarian collision cases. Ovarian tumors from all classes, benign, borderline and malignant lesions may collide. Both our case series and the literature review indicate that ovarian tumor collisions tend to be clinically and ultrasonographically/radiologically unrecognized. The awareness among surgeons, radiologists and pathologists of this rare phenomenon and histological recognition are crucial in order to offer adequate treatment to patients. There is a need to identify novel and more specific imaging clues pointing towards collision tumors in the ovary.

Objective: To determine the difference of HER2/neu expression in benign, borderline and malignant epithelial ovarian tumor. Method: An analytic cross-sectional study was performed on 49 samples of epithelial ovarian cases which were divided into three groups: twelve cases of benign epithelial ovarian tumor, 9 cases of borderline epithelial ovarian tumor and 28 cases of malignant epithelial ovarian tumor. Paraffin embedded tissue samples was cut, stained with HER2/neu imunohistochemistry and examined in Pathology Laboratory at Sanglah Hospital. The other data was collected from medical record samples. The data was analysed using One Way Anova test and Chi-square test with level of confidence α = 0.05. Result: There were 13 cases (46.43%) of the HER2/neu over expression in malignant epithelial ovarian tumors, 2 cases (22.22%) of the HER2/neu over expression in borderline epithelial ovarian tumors and 1 case (9.09%) of the HER2/neu over expression in benign epithelial ovarian tumors. With p = 0.048 (p < 0.05), there are differentiation of HER2/neu expression in benign, borderline and malignant epithelial ovarian tumors. Conclusion: In this study HER2/neu expression was different between benign, borderline and malignant epithelial ovarian tumors. Keywords: benign epithelial ovarian tumor, borderline epithelial ovarian tumor, HER2/neu, malignant epithelial ovarian tumor, ovarian cancer.

Mucinous Ovarian Tumors

A collision tumor is the coexistence of two adjacent, but histologically distinct tumors without histological admixture in the same tissue or organ. Such tumors have often been reported in various organs, but location in the ovary is rare. The juxtaposition with dermoid cysts has been reported as comprising approximately 5% of benign mucinous ovarian tumors and rare examples of proliferating mucinous tumors. Authors are reporting a case of collision tumor which included benign mucinous cystadenoma and benign cystic teratoma. The gynecologists and pathologists should be aware of such combination of tumors. The case was diagnosed post-operatively. It is important to correctly diagnose the component of tumor for further management and favourable prognosis. Frozen section intra-operatively plays an important role in diagnosing such tumors.

ABSTRACT Introduction Incomplete initial surgery complicates subsequent management of ovarian tumors. This study aimed to study demographic and clinical factors associated with incompletely staged ovarian tumor patients. Materials and methods Twenty five patients who had undergone incomplete staging surgery for ovarian tumors outside Gujarat Cancer & Research Institute, Ahmedabad, Gujarat, India, were included in this study. Their demographic and clinical features were studied in detail. Patients were either subjected to restaging or were referred for chemotherapy initially. Results Mean age of patients was 42 years (23—60 years); 64% of patients had abdominal pain as initial complaint; 64% patients were operated initially using a transverse incision. Only four patients were managed laparoscopically initially, others by laparotomy. Single/part of one ovary was removed in 60% of patients as part of initial surgery. Infundibulopelvic ligament was tied distally in 40% of patients. Omentectomy (Om) and lymphadenectomy were not done in most of the patients. Nineteen patients were found to have malignancy on final histopathological examination; 3 borderline malignancy; 1 granulosa cell tumor; and 2 benign tumors; 52% (n = 13) patients were subjected to chemotherapy; 4% (n = 1) were observed, and rest underwent restaging procedures. Conclusion Incompletely staged ovarian tumor patients, especially those with malignant histopathology, should be managed by gynecologic oncologists. The management needs to be individualized and cannot be a blanket therapy. How to cite this article Kamath A, Dave P, Mankad M.

ABSTRACT Collision tumors are distinct and rare groups of neoplasms characterized by occurrence of two histologically different neoplasms at one site as a single lesion without significant tissue admixture. They are described in different parts of the body including adrenal glands. Collision tumors reported in relation to adrenal gland are mainly combinations of adenoma and metastasis. Here we present a case of incidentally detected adrenal collision tumor with adenoma and hemangioma as components which is a very rare and unique occurrence.

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

This study focuses on the fabrication of an anisotropic textile brace that exerts corrective forces based on the three-point pressure system to treat scoliosis, which is a medical condition that involves deformity of the spine. The design and material properties of the proposed anisotropic textile brace are discussed in detail here. A case series study with 5 scoliosis patients has been conducted to investigate the immediate in-brace effect and biomechanics of the proposed brace. Radiographic examination, three-dimensional scanning of the body and interface pressure measurements have been used to evaluate the immediate effect of the proposed brace on reducing the spinal curvature and asymmetry of the body contours and its biomechanics. The results show that the proposed brace on average reduces the spinal curvature by 11.7° and also increases the symmetry of the posterior trunk by 14.1% to 43.2%. The interface pressure at the corrective pad ranges from 6.0 to 24.4 kPa. The measured interface pressure shows that a sufficient amount of pressure has been exerted and a three-point pressure distribution is realized to reduce the spinal curvature. The obtained results indicate the effectiveness of this new approach which uses elastic textile material and a hinged artificial backbone to correct spinal deformity.
