Thyroid neoplasms: surgical and cyto-histopathological connections on a six year cases study
2018
This study aims to evaluate the percentage of cyto-histologic correlation in patients with a thyroid disease documented through clinical-instrumental, cytological (FNAB), histological and surgical examinations. The purpose of this study is also to determine the percentage of disease incidence and evaluating any surgical indication in relation to biological behavior (benign, malignant or indeterminate lesions, occult carcinomas), sex, and age.Almost all of thyroid neoplasms is manifested through thyroid nodule. Therefore, clinical evidence of the thyroid nodule analysis is primarily related to the need to exclude malignant pathology or carcinoma of the thyroid, present in 4-6.5% of cases.The…
Involvement of the chromosomal region 11q13 in renal oncocytoma: case report and literature review.
1997
Renal oncocytomas comprise a cytogenetically heterogeneous group of tumors consisting potentially of cytogenetic distinguishable subgroups. Review of the literature revealed loss of chromosome 1 and Y as a possible anomaly for at least one subset of oncocytomas. The frequent finding of rearrangements involving chromosome 11 band q13 characterizes another subset of oncocytomas. We report the cytogenetic and pathological features of a renal oncocytoma diagnosed in a 72-year-old woman and found a t(9;11)(p23;q13) as a consistent abnormality. This supports the idea that translocations involving 11q13 define a further subset of oncocytoma. (C) Elsevier Science Inc., 1997.
A singular case of near-haploid stemline karyotype in a renal oncocytoma.
1996
Cytogenetic analysis of a human renal oncocytoma revealed a near-haploid chromosome number of 36 with the loss of chromosomes 1, 2, 3, 6, 8, 9, 15, 17, 21, and 22. Review of the literature disclosed that this cytogenetic configuration is extremely rare in solid human tumors and that no renal oncocytomas with near-haploid stemline karyotype have been described. These results are compared with the other published cases of oncocytoma.
