Retroperitoneal teratoma misdiagnosed as a gastric stromal tumor: A case report.

Mol Clin Oncol 2020 Jun 19;12(6):525-528. Epub 2020 Mar 19.

Department of Gastrointestinal Surgery, The First Affiliated Hospital, University of South China, Hengyang, Hunan 421001, P.R. China.

The misdiagnosis of retroperitoneal teratoma as a gastric stromal tumor is rarely reported. There are numerous abdominal organs, and retroperitoneal tumors are easily concealed by organs situated more anteriorly on the abdomen; therefore, retroperitoneal tumors are easily misdiagnosed as human digestive system tumors by abdominal surgeons. We herein present the case of a 39-year-old female patient who was diagnosed with a gastric stromal tumor (GST) on preoperative examination, whereas the postoperative diagnosis was retroperitoneal mature cystic teratoma.

Department of Obstetrics and Gynecology, Niigata University Graduate School of Medical and Dental Sciences, Niigata, 951-8510, Japan.

Molecular characteristics of carcinoma arising from mature cystic teratoma of the ovary (MCT) remain unclear due to its rarity. We analyzed RNA-sequencing data of 2322 pan-cancer [1378 squamous cell carcinomas (SCC), 6 adenosquamous carcinomas (ASC), and 938 adenocarcinomas (AC)] including six carcinomas arising from MCT (four SCCs, one ASC, and one AC). Hierarchical clustering and principal component analysis showed that gene expression profiles of carcinomas arising from MCT were different between each histological type and that gene expression profiles of SCCs arising MCT (MCT-SCCs) was apparently similar to those of lung SCCs.

Surgical Treatment of Massive Teratoma of the Orbit.

Ophthalmic Plast Reconstr Surg 2020 May/Jun;36(3):e68-e70

Division of Maxillofacial Surgery, Surgical Science Department, Maxillofacial Unit, University of Torino, Torino, Italy.

Orbital location of teratoma is extremely rare. The differential diagnosis can be difficult and they may be mistaken for other tumors as they may have both cystic and solid areas. The authors report a case of a 7-day-old neonate with a massive congenital orbital teratoma in which it was decided to apply a surgical technique that involves the aspiration of the cystic fluid, the subsequent infusion of fibrin glue, and the radical excision.

[Testicular tumors in prepubertal boys-organ preservation possible more often than expected].

Urologe A 2020 Mar;59(3):278-283

Zentrum für Kinder‑, Jugend- und rekonstruktive Urologie, Medizinische Fakultät Mannheim, der Universität Heidelberg, Universitätsklinikum Mannheim GmbH, Theodor-Kutzer-Ufer 1-3, 68167, Mannheim, Deutschland.

In prepubertal boys, testicular tumors are rare with an incidence between 2 and 5/million. In contrast to testicular tumors in adolescents and adults, more than 2/3 of these tumors are benign. Unfortunately, in Germany in most cases, only malignant tumors (usually yolk sac tumors) are reported to the study center (MAKEI IV and now V). Read More

Cystic trophoblastic tumor - The effect of chemotherapy in metastatic testicular germ cell tumor to retroperitoneal lymph nodes.

Urol Ann 2020 Jan-Mar;12(1):73-76. Epub 2019 Dec 23.

Department of Surgical Oncology, Apollo Cancer Institutes, Chennai, Tamil Nadu, India.

Cystic trophoblastic tumor is an uncommon lesion which is occasionally seen after chemotherapy in metastatic retroperitoneal lymph nodes in patients with testicular germ cell tumor. The tumor cell clusters show cystic change lined by single to multiple layers of cells with abundant dense eosinophilic vacuolated cytoplasm, large pleomorphic vesicular nuclei with smudged chromatin, and prominent nucleoli. It is important to identify this lesion as its prognosis is similar to a teratoma and does not require any additional chemotherapy. Read More

Concomitant Presence of Ovarian Tumors (Teratoma and Granulosa Cell Tumor), and Pyometra in an English Bulldog Female Dog: A Case Report.

Front Vet Sci 2019 14;6:500. Epub 2020 Jan 14.

Surgery and Theriogenology Branch OHVRI-Group, School of Veterinary Medicine, University of Antioquia, Medellin, Colombia.

The diagnosis of ovarian tumors in dogs is usually complicated because the clinical signs can be very discrete and can be easily confused with other diseases. There are few reports of ovarian tumors with different cellular characteristics in the same dog. Our objective was to describe an unusual case of the concomitant presence of ovarian teratoma and granulosa cell tumors in a female dog presenting symptoms compatible with pyometra at clinical consultation.

Is There a Role of Elevated CA 19-9 Levels in the Evaluation of Clinical Characteristics of Mature Cystic Ovarian Teratomas? A Systematic Review and Meta-analysis.

Cureus 2019 Dec 10;11(12):e6342. Epub 2019 Dec 10.

Obstetrics and Gynecology, Alexandra Hospital, National and Kapodistrian University of Athens, Athens, GRC.

The role of preoperative CA 19-9 levels in patients with ovarian mature cystic teratoma (MCT) and the association of elevated levels of the biomarker with patients' and tumor characteristics were evaluated. Four electronic databases were searched for articles published up to September 2019. Trials that evaluated the significance of elevated CA 19-9 in patients with ovarian MCTs and publications with > 20 patients were considered eligible for inclusion. Read More

Ovarian microcystic stromal tumors: clinical, radiological, and pathological studies of two cases.

Int J Clin Exp Pathol 2019 1;12(6):2241-2248. Epub 2019 Jun 1.

Department of Gynecology, Affiliated Yantai Yuhuangding Hospital, Qingdao University Yantai, China.

We observed two unusual cases of ovarian microcystic stromal tumors (MST). These two patients had no obvious clinical symptoms, and the imaging findings were separately diagnosed as cystic teratoma and ovarian malignant tumors. Significantly, during the operation, none of the pathologists considered the possibility of MST. Read More

Fetal mediastinal teratoma: Misinterpretation as congenital cystic lesions of the lung on prenatal ultrasound.

J Clin Ultrasound 2020 Jun 20;48(5):287-290. Epub 2019 Dec 20.

University of Tunis El Manar, Tunis, Tunisia.

Congenital mediastinal teratoma can lead to development of hydrops fetalis and may be misinterpreted on ultrasound. In this case report, ultrasound revealed severe fetoplacental hydrops, moderate posthemorrhagic hydrocephalus, and multiple pulmonary cysts suggesting cystic adenomatoid malformation and displacement of the heart to the left side. Autopsy of the hydropic 24-weeks male fetus showed a large cystic-solid mediastinal mass that was consistent with nonmetastatic immature teratoma. Read More
