In this study, the majority of thyroid neoplastic lesions were found to be follicular neoplasm, followed by papillary carcinoma
Histologic analysis after a Sistrunk procedure revealed a small focus of papillary carcinoma
within the TGDC.
10 Histopathological evaluation showed 29 tumours; 21 were chromophil basophilic papillary carcinoma
; 5 were clear cell RCC; and 1 was chromophil eosinophilic papillary carcinoma
8] Small cell RCC is classified into 3 main cellular types: (1) clear cell carcinoma (78%), (2) papillary carcinoma
On repeat FNA, 6 of these 24 patients (25%) were found to have papillary carcinoma
On repeat biopsies, 6 of the 24 patients (25%) were found to have papillary carcinoma
Numerous clinical studies demonstrated an association of BRAF mutation with aggressive clinicopathological outcomes, including tumour invasion, metastasis, and recurrence of Papillary carcinoma
She highlights essential morphologic and immunohistochemical features of intraductal papilloma (IDP) (central and peripheral), atypical IDP, IDP with DCIS, papillary DCIS, papillary carcinoma
, and solid papillary carcinoma
35] Of the 268 malignant lesions, most common diagnosis was infiltrating duct carcinoma (N = 229), followed by medullary carcinoma (N = 2) and mucinous carcinoma, infiltrating lobular carcinoma, sarcomatoid carcinoma, invasive papillary carcinoma
, and secretory carcinoma with one case each [Table 3].
Ectopic thyroid tissue within a branchial cleft cyst is rare, and a papillary carcinoma
arising from this tissue is extremely rare.
12 The cytologic characteristic of papillary carcinoma
is typical but a follicular carcinoma cannot be diagnosed on FNAC.
HPE diagnosis revealed that the most common lesion was colloid nodule (35%) followed by nodular goitre (32%), benign follicular adenoma (15%); 8 out of 32 NG cases were showing adenomatous hyperplasia; 13% of cases were papillary carcinoma
and 1 case was reported as marginal B cell lymphoma.
