Background: Ovarian cysts, which present as neoplastic and non-neoplastic lesions, are the most common gynecological cause of hospital admissions. This study was conducted to know the spectrum of ovarian tumors.Materials and methods: A cross sectional study was carried out among all the ovarian specimens sent for histopathological examination.Results: Forty two cases were Surface epithelial tumours and 49 cases were germ cell tumour. Among Surface epithelial tumours, 34 (80.95%) were benign neoplasm, 2(4.76%) were borderline and 6 including one Krukenberg tumour (14.29%) were malignant neoplasm. Among all Germ cell tumours, 45 (91.84%) were Mature cystic teratoma, 1 (4.08%) was Immature cystic teratoma and 2 (4.08%) were Dysgerminoma. Conclusion: Incidence of Surface epithelial tumours and germ cell tumours were found to be almost equal with mild predominance of Germ cell tumour.

Mixed germ cell tumours of testis represent a comparatively rare category of testicular tumour where different types of both seminomatous and non-seminomatous tumours can be present in varied proportions. We report two cases of mixed germ cell tumours, one consisting of seminoma, embryonal carcinoma and post-pubertal teratoma in the testis of a 22-year-old male and second consisting of a yolk sac tumour and immature teratoma in the testis of a 19-year-old male. We report theses case due to the rare combination and for documentation

Testicular cancer commonly affects younger men, with testicular germ cell tumours comprising the vast majority of cases. They are classified into either seminomatous or non-seminomatous germ cell tumours, with mixed germ cell tumours treated as non-seminomas. In the following case report, we describe the clinical course and management of a 38-year-old male patient who presented with a right unilateral testicular mixed germ cell tumour, predominantly seminoma that had metastasized to the adrenal gland. This pattern of spread is indeed a rare occurrence. It also highlights the significance of the current diagnostic and management protocol and the benefits of using positron emission tomography as a diagnostic tool. Level of evidence: 4

Stanislovas Jonas Maknavičius, Arūnas Valiulis, Žydrūnė PrapuolenienėVilniaus universiteto Vaikų ligoninės Vaikų chirurgijos centras, Santariškių g. 7, LT-08406 VilniusEl paštas: [email protected] Įvadas / tikslas Germinogeniniai navikai yra ankstyvo embrioninio vystymosi užuomazginių germinogeninių ląstelių virtimo į gametą stadijos navikai. Šie navikai kyla ne tik gonadose, bet ir embriono vidurinės linijos organuose – kankorėžinėje liaukoje, priekiniame tarpuplautyje, kryžkaulio ir uodegikaulio srityje, retroperitoniniame tarpe. Neretai germinogeninės ląstelės migruoja į organus ir juose išauga mišrių ektopinių germinogeninių ir negerminogeninių audinių navikai: teratomos, teratoblastomos, embrioninės karcinomos, endoderminio sinuso karcinomos, seminomos, disgerminomos ar mišrių ląstelių germinogeniniai navikai (dažniausiai). Darbo tikslas – išnagrinėti vaikų tarpuplaučio germinogeninių navikų diagnostikos, klinikos, tyrimo ir chirurginio gydymo taktikos ypatumus. Ligoniai ir metodai Retrospektyviai analizavome vaikų, 1995–2007 metais gydytų Vilniaus universiteto vaikų ligoninės 1-jame chirurgijos (torakalinės ir abdominalinės chirurgijos) skyriuje dėl tarpuplaučio germinogeninių navikų, ligos istorijas, operacijų protokolus, tyrimų duomenis. Ligoniai buvo tirti klinikiniais metodais, atlikti naviko žymenų tyrimai, rentgenogramos, kompiuterinės tomogramos, echoskopija, angiogramos. Rezultatai Mūsų gydytiems 8 vaikams brandūs navikai rasti penkiems ir nebrandūs – trims. Užkrūčio liaukoje navikai rasti 7 vaikams, ne užkrūčio liaukoje – 1 vaikui. Piktybiniai germinogeniniai navikai užkrūčio liaukoje buvo 3 vaikams, gerybiniai germinogeniniai navikai užkrūčio liaukoje rasti 4 vaikams ir 1 ligonei gerybinį germinogeninį naviką radome ant aortos kylančiosios dalies, suaugusį su užkrūčio liaukos užpakaliniu paviršiumi. Kvėpavimo sutrikimas, karščiavimas, obstrukcijos simptomai buvo visiems vaikams. Dėl šių simptomų tėvai kreipėsi į gydytojus. Septyni vaikai buvo operuoti ir navikai pašalinti, o vieno vaiko tėvai radikalios operacijos atsisakė (diagnozė nustatyta kliniškai, rentgeniškai). Sergantiesiems piktybiniais germinogeniniais navikais po operacijos taikyta chemoterapija. Dviem vaikams navikai šalinti atlikus sternotomiją, 5 vaikams – per torakotominius pjūvius. Saugiau operuoti atlikus sternotominį pjūvį, ypač jei navikas išplitęs ir yra užkrūčio liaukoje. Po operacijos vaikai pasveiko. Išvados Vaikų tarpuplaučio germinogeniniai navikai yra polipotentinės histologinės struktūros, jų augimas greitas, skvarbus. Pagrindiniai klinikiniai simptomai – krūtinės skausmas, kvėpavimo sutrikimas, v. cava superior sindromas, anemija, alfa-fetoproteino kiekio ir choriogonadotropinio hormono kiekio padidėjimas. Pagrindiniai diagnostikos metodai – rentgeniniai, echoskopija, angiografiniai. Pagrindinis gydymo metodas yra chirurginis: naviko ekstirpacija per sternotominę, torakotominį prieigą, ar videotorakoskopiniu būdu. Operavome 7 vaikus, navikai pašalinti, diagnozės pagrįstos histologiniais tyrimais.

It may be benign or malignant, or cystic and contain three types of embryonal developing tissue – ectoderm, mesoderm and endoderm. Germ cell tumour can be seminomatous, nonseminomatous and originate from ectopic tissues in the mediastinum. Malignant tumours lesions grow and invade the surrounding structures. Germ cell tumour of the mediastinum in children may present with early puberty in Klinefelter’s syndrome. Children with malignant germ cell tumours often have elevated alpha-fetoprotein and serum beta-chorionic gonadotropin levels. The aim of this study was to review the spectrum of clinical symptoms, diagnostics methods and tactics of the surgical treatment. Patients and methods We analysed retrospectively 8 children’s case histories with primary germ cell tumours in the period 1995–2007. Clinical symptoms, diagnostic methods, methods of surgical treatment and histological diagnoses were analysed. Results Three patients had malignant and five patients had benign tumours. Respiratory distress syndrome was present in all patients. Qur data are based on histological analysis after operations. Seven patients were operated on. The tumours were removed. Conclusions Mediastinal germ cell tumours in children are embryonal multipotentional histological structures of embryonic origin, developing of endodermal, mesodermal and ectodermal tissues. The most frequent symptoms were respiratory distress, chest pain, temperature, cough and wheezing. Patients with teratomas of germ cell tumours often have an elevated level of alpha-fetoprotein and serum beta-human gonadotropin. Seven patients were operated on, tumours were removed, and diagnoses were based on histological analysis. Key words: mediastinal tumours in children, mediastinal germ cell tumour in children, benign and malignant mediastinal teratoma

Abstract INTRODUCTION Patients with localised CNS-germinoma have excellent survival. More recently, intensive inpatient chemotherapy (carboPEI=carboplatin/etoposide/ifosfamide in Europe) has been effectively employed to reduce radiotherapy fields and/or dose. Current research priorities focus on reducing treatment burden and long-term sequelae. Of note, outpatient-based single-agent carboplatin chemotherapy is associated with excellent outcomes in metastatic testicular seminoma (an identical pathology) [Alifrangis,EJC,2020]. Recently, successful vinblastine monotherapy was reported in localised CNS-germinoma [Murray,Neurooncol-Adv,2020]. METHODS Due to the COVID-19 pandemic, adapted UK guidelines for germ-cell-tumour management were distributed, including potential non-standard treatment options that would reduce hospital visits/admissions. A 30-year-old patient presented with a 32mmx30mmx35mm diameter solid+multi-cystic localised pineal CNS lesion, consistent radiologically with a germ-cell-tumour with prominent teratoma component. Investigation revealed negative AFP/HCG markers and biopsy-proven pure germinoma. After appropriate consent, the patient commenced 12-week induction with weekly vinblastine monotherapy (low-grade-glioma dosing [Lassaletta,JCO,2016]), with wk6&12 MRI re-assessment prior to definitive radiotherapy. RESULTS Vinblastine was well-tolerated. After initial 4mg/m2 test-dosing (wk1), standard 6mg/m2 was delivered for wk2, but resulted in asymptomatic neutropenia (nadir 0.3x10^9/l) and missed dosing at wk3. Subsequent doses were 4mg/m2, with no further neutropenia. As expected, MRI showed moderate 40% tumour volume reduction by wk12. Surgical resection of the residual presumed teratoma component was undertaken prior to radiotherapy. CONCLUSION Patients with CNS-germinoma have excellent outcomes and reduction of treatment-effects remains a priority. The exquisite chemosensitivity of germinoma, excellent results from monotherapy for metastatic testicular disease, and early promise of vinblastine monotherapy lend itself to further exploration for CNS-germinoma.
