Anti-NMDA receptor (NMDAR) encephalitis is an autoimmune antibody-mediated neuropsychiatric disorder. The disorder is known to be associated with ovarian teratoma and predominantly affects young women. Here, we report the case of a 34-year-old woman with anti-NMDAR encephalitis, in which detailed investigations gave no specific hint for an ovarian teratoma. Despite this, and due to a continuous...
Autoimmune hemolytic anemia associated with an ovarian teratoma is a very rare disease. However, treating teratoma is the only method to cure the hemolytic anemia, so it is necessary to include ovarian teratoma in the differential diagnosis of autoimmune hemolytic anemia. We report herein on a case of a young adult patient who had severe autoimmune hemolytic anemia that was induced by an ovaria...
Teratomas are tumors originated from mature or immature tissues. Teratomas are made up of one embryonic layer or all three embryonic layers (endoderm, mesoderm, or ectoderm). Herein we report a 41-year-old man who presented with vertigo, vomiting, and tinnitus. After physical examination, laboratory evaluation and performing computed tomography, cholesteatoma was diagnosed, however, during radi...
Background: Mature cystic teratoma of the ovary is one of the most common benign ovarian tumors, which may be confused with other adnexal lesions due to its extensive manifestations on ultrasound. Therefore, in this study, we tried to reduce the need for pathology frozen sections by examining more accurate preoperative ultrasound results and classifying ovarian lesions based on them. Methods: ...
Transplantation of stem cells represents an upcoming therapy for many degenerative diseases. For clinical use, transplantation of pluripotent stem cell-derived cells should lead to integration of functional grafts without immune rejection or teratoma formation. Our previous studies showed that the risk of teratoma formation is highly influenced by the immune system of the recipients. In this st...
Growing Teratoma Syndrome (GTS) is defined as the occurrence of a tumor mass consisting exclusively of mature teratoma, combined with normal tumor marker levels, during or after chemotherapy in patients with Non Seminomatous Germ Cell Tumors (NSGCT). We report two cases of GTS. Case 1 is a woman with concomitant retroperitoneal mass invading the muscular layer of abdominal wall, and scattered n...
BACKGROUND Germ cell tumors are tumors composed of tissues derived from more than one of the three germinal layers. They are more common in the testes and ovaries, but can present in many different regions in the midline, including the sacral region, retroperitoneum, mediastinum, and brain. Testicular germ cell tumors generally metastasize to the retroperitoneum, lungs, and brain; metastases to...
INTRODUCTION This case report illustrates a rare case of teratoma of the mediastinum which was continuous to the pericardium and caused extrinsic compression to the right atrium. CASE PRESENTATION A 22-year-old Caucasian man with no complaints or comorbid conditions presented to our hospital with obliteration of the right cardiophrenic sinus by a mass. A non-invasive investigation demonstrate...
Sacrococcygeal teratoma is one of the most common tumours in infants but rare in adults. We present a case of sacrococcygeal teratoma in a female adult. The clinical presentation, radiological and histological findings, management, and outcome are described.
