Hyaline globules and papillary fragments in cytologic smears from two intra-abdominal tumors (ovarian and hepatic) in female patients: A diagnostic p…
2016
Hyaline globules and papillary fragments in cytologic samples from two intra-abdominal tumors in young females are presented including the cytological features and the correlation with the histopathologic and immunohistochemical findings. In the first case a cytologic study from an ovarian mass showed papillary structures and isolated tumor cells with epithelioid morphology, irregular reniform-like nuclear contour, pale or vacuolated cytoplasm, abundant hyaline globules and occasional glomeruloid structures resembling Schiller-Duval bodies. Yolk sac tumor (YST) was the diagnosis on the histological slides. Tumor cells showed positivity for cytokeratin (AE1/AE3), epithelial membrane antigen …
IL TERATOMA CERVICALE
1991
The Authors present a case of Cervical Teratoma in newborn and analyze the optimal diagnostic and therapeutic approach.
IL TERATOMA ED IL CHIRURGO PEDIATRA. Considerazioni sull'approccio e valutazioni dalla Casistica Nazionale "TCG 91".
1996
Germ Cell Tumors (GCT) are rare in childhood, accounting for 2-4% of all solid neoplasms. Teratoma is the most frequent histological type (50%) of GCT and the most important neonatal tumors.. Authors analyze the results of the first Italian Multicentric Cooperative Study on GCTs in childhood (TCG 91). The role of surgical radical excision of the mass with thw coccyx in sacrococcygeal forms is streassed.
The 2021 WHO Classification of Tumors of the Thymus and Mediastinum: What Is New in Thymic Epithelial, Germ Cell, and Mesenchymal Tumors?
2022
Abstract This overview of the fifth edition of the WHO classification of thymic epithelial tumors (including thymomas, thymic carcinomas, and thymic neuroendocrine tumors [NETs]), mediastinal germ cell tumors, and mesenchymal neoplasms aims to (1) list established and new tumor entities and subtypes and (2) focus on diagnostic, molecular, and conceptual advances since publication of the fourth edition in 2015. Diagnostic advances are best exemplified by the immunohistochemical characterization of adenocarcinomas and the recognition of genetic translocations in metaplastic thymomas, rare B2 and B3 thymomas, and hyalinizing clear cell carcinomas. Advancements at the molecular and tumor biolog…
Near-Haploidy in a Malignant Sacrococcygeal Teratoma
1999
Cytogenetic analysis of a malignant sacrococcygeal teratoma in an adult patient revealed near-haploid (77%), near-diploid (19%), and polyploid (4%) cells. The near-haploid cells had a karyotype of 25,XX,der(5)t(5;7)(p15;p13),+7,der(9)t(6;9)(p21;q34),r(17)(p13q25) . In the near-diploid and polyploid cells identical copies of the structural chromosomal changes were found. Although some of the anomalies observed appear unique to this case, a common breakpoint in chromosome 6 was previously reported as specific in a subgroup of extragonadal germ cell tumors of adults.
EXTRAGONADAL GERM CELL TUMORS: Results of AIEOP TCG 91/98 Protocols
2002
The aim of the Study: To analyze the outcome of patirnts with extragonadal (eg) GCT teated with TCG 91/98 Protocols. 45 pts were enrolled: 34 were females, 11 males; median age 17 months (range: 1-137 months)
THE ROLE OF SURGERY (s) IN THE TREATMENT OF GERM CELL TUMORS (GCT) IN CHILDHOOD. A Report from an Italian Multi-Istitutional Study (TCG-91)
1993
GCT account for about 3% of all solidi Neoplasms in children. Because of the confusion as to their classification, diagnostic apporoach and treatment, a multi-istitutional study was carried and a National Protocol for Diagnosis and treatment of CGT (TCG-91), approved by AIEOP, straded in January 1991.
STAGE I GONADAL CELL TUMORS (GGCT): OUTCOME AFETR THE SURVEILLANCE STRATEGY AS APPLIED IN THE ASSOCIAZIONE ITALIANA EMATOLOGIA ONCOLOGIA PEDIATRICA (…
2012
Suveillance strategy is a standerd option in stage 1° testicular GCT and suggested for ovarian GCT too. Worries regarding the relapse risk in ovarian are emerging. We here report on our series of stage 1° GGCT
MALIGNANT NON-SEMINOMATOUS GERM CELL TUMORS (MNSGCT) IN CHILDREN: Results of a Study of Italian Association Pediatric Oncology (AIEOP).
1995
The authors report the results of the Italian study on the treatment of non-seminomatous germ cell tumors in pediatric age and present the results of the diagnostic and therapeutic process in their experience
IL RUOLO DELLA CHIRURGIA NEL TRATTAMENTO DEI TUMORI GERMINALI IN ETA' PEDIATRICA: Analisi dello Studio Cooperativo "AIEOP TCG-'91.
1993
Authors analyze the preliminary results of the first multicentric cooperative study on Germ Celkl Tumors in childhood (TCG 91). The Authors discuss the role of primary surgical procedure on the treatment of benign forms and of resectable malignant tumors.
