Sensitivity of fine-needle aspiration for papillary
carcinoma of the thyroid correlates with tumor size.
Although such preoperatively performed examinations may allow for the appropriate patient management, diagnosis of thyroid papillary
carcinomas that metastasize into the branchial cyst wall, as reported in the literature and as was the case in our patient, is possible only by a histopathologic examination performed after surgery.
There were 6 cases of papillary
micro carcinoma, 5 cases of follicular variant, 4 cases of mixed papillary
and follicular, 2 cases each of tall cell variant and solid variant and a single case each of Warthin like variant and encapsulated variant (Table 1).
(2) All tumors demonstrated cystic components and stromal invasion, and approximately 75% of cases demonstrated intraluminal cystic papillary
In this case report, we present a very rare case in literature, a case of postoperatively diagnosed oncocytic and tall columnar type papillary
thyroid carcinoma arising on a mature cystic teratoma without any natural thyroid tissue.
Clinical and pathologic data were analyzed and classified into two groups according to study criteria (age, sex, tumor size, histologic subtype, intraglandular dissemination, extrathyroid dissemination, and metastases): group 1 with favorable prognosis (low risk) included patients aged <45, female, tumor size up to 2 cm, papillary
and follicular subtype limited to the thyroid, no intraglandular dissemination, and absence of metastases; and group 2 with poor prognosis (high risk) included all those that did not meet all group 1 criteria, i.e.
H & E stained sections of the lung core biopsy showed multiple fragments of a tumour having a complex papillary
fibroelastomas are avascular tumors originating from fibrous tissue, elastic fibers and smooth muscle cells (5).
To the question 'for a patient with a <1cm diameter papillary
cancer incidentally detected after hemithyroidectomy, do you recommend completion surgery if residual lobe is ultrasonographically normal?', while 41% of the participants answered as 'yes', 59% answered as 'no'.
Cohort 3 patients are those with papillary
disease without CIS who underwent mandatory tumor resection at screening and had no visible evidence of the disease.
(9) Histologically, this lesion is well-circumscribed and it is characterized by a papillary
proliferation of endothelial cells forming vascular channels.
The lesion was reported as intracystic mass with a preliminary diagnosis of papillary
