Spontaneous rupture ‑induced life‑threatening mediastinal mixed germ cell tumor: A case report and therapeutic considerations
Oncol Lett. 2024 Feb 28;27(4):183. doi: 10.3892/ol.2024.14316. eCollection 2024 Apr.ABSTRACTSpontaneous rupture and hemorrhage of mediastinal germ cell tumors is a rare occurrence. In the current report, the case of a 20-year-old male patient who was admitted with chest tightness and dyspnea is presented. An urgent chest CT scan revealed a large tumor in the right anterior mediastinum, measuring ~12 cm in diameter, with associated intratumoral hemorrhage. An emergency thoracotomy was performed to excise the lesion, which revealed that the bleeding was caused by a ruptured tumor. Postoperative pathological findings revealed...

A rare case of tumor ‐to‐tumor metastasis from thymic carcinoma to an ovarian mature teratoma
This is the first case of tumor-to-tumor metastasis (TTM) from a donor thymic carcinoma to a recipient ovarian mature teratoma. A 25-year-old woman who was diagnosed with unresectable thymic carcinoma presented with a cyst with a solid tumor component in her right ovary. Laparoscopic cystectomy of the right ovary revealed that the solid tumor was a distant metastasis of the thymic carcinoma in an ovarian mature teratoma. When investigating potential distant metastases, histopathological confirmation of TTM is beneficial. AbstractMetastasis from one neoplasm to another is referred to as tumor-to-tumor metastasis (TTM). TTM ...

Unusual imaging findings associated with abdominal pediatric germ cell tumors
AbstractGerm cell tumors of childhood are tumors arising from germline cells in gonadal or extragonadal locations. Extragonadal germ cell tumors are characteristically located in the midline, arising intracranially or in the mediastinum, retroperitoneum, or pelvis. These tumors are generally easily diagnosed due to typical sites of origin, characteristic imaging findings, and laboratory markers. However, germ cell tumors can be associated with unusual clinical syndromes or imaging features that can perplex the radiologist. This review will illustrate atypical imaging/clinical manifestations and complications of abdominal g...

Mature Teratoma with Malignant Brenner Tumour: A Rare Ovarian Collision Tumour Case Report and Literature Review
AbstractCollision tumor is existence of distinct tumors in the same tissue or organ without admixture. Although any histological type of ovarian tumor may occur in collision tumor, the mature teratoma is one of the most found component. Brenner tumor is a rare epithelial tumor of ovary and the coexistence of it with teratoma in collision tumour is sparsely reported in literature. Here we describe a case of mature teratoma with malignant Brenner tumor diagnosed post-operatively on histopathological and immunohistochemical examination. It is of paramount importance to correctly diagnose the histological components of collisi...

Hybrid Lymphovenous Anastomosis Surgery Guided by Intraoperative Mesenteric Intranodal Lymphangiography for Refractory Nontraumatic Chylous Ascites: A Case Report
This article introduces a case of a 22-year-old female patient with an underlying lymphatic anomaly who presented with refractory chylous ascites after laparoscopic adnexectomy for ovarian teratoma which aggravated after thoracic duct embolization. Ascites (>3,000 mL/d) had to be drained via a percutaneous catheter to relieve abdominal distention and consequent dyspnea, leading to significant cachexia and weight loss. Two sessions of hybrid lymphovenous anastomosis (LVA) surgery with intraoperative mesenteric lymphangiography guidance were performed to decompress the lymphatics. The first LVA was done between inferior m...

CK7+/CK20+/CDX2+ mucinous carcinoma, arising in a mature cystic teratoma of ovary, presenting with disseminated metastasis and pseudomyxoma peritonei
In this report, we have described a case of a well-differentiated mucinous carcinoma arising within a mature cystic teratoma. The mucinous carcinoma showed a spectrum of morphological patterns, including cystadenoma-like areas, proliferative/borderline areas, villous adenoma-like areas, and areas of invasive carcinoma. In addition, our case showed some unusual findings, namely, diffuse CK7 positivity, associated pseudomyxoma peritonei, and metastasis to lungs. These features were not demonstrated in any of the previously reported cases. Our case shows that the teratomatous mucinous neoplasm of the ovary may show CK7+/CK20+...
