Warthin tumor-like papillary thyroid carcinoma is an uncommon variant of papillary thyroid carcinoma. We report a rare case of Warthin tumor-like variant of papillary thyroid carcinoma with a dedifferentiated component consisting of a solid tumor area composed of neoplastic cells with a spindle to tall cell morphology associated with marked nuclear pleomorphism, atypical mitoses, and foci of ne...

Parotid metastasis originated from papillary thyroid carcinoma is extremely rare, especially as the first presentation of the disease. We present a 70-year-old man with a history of painless swelling in the right side of the neck. He was evaluated for parotid tumor and histopathologic examination revealed a poorly differentiated carcinoma in the parotid gland with suspicion of thyroid origin. T...

background: thyroid carcinoma is the most common malignancy of the endocrine system. papillary thyroid carcinoma (ptc) is the most common type of thyroid cancer, accounting for 70–90% of well-differentiated thyroid malignancies. thyroid papillary microcarcinoma is a subtype of papillary carcinoma that included tumors with less than 10mm diameter. as a result of diagnostic methods improvement, p...

papillary microcarcinoma of thyroid (pmc) as a variant of papillary carcinoma less than 1 cm in size is a new clinicopathological entity, with high incidence and good prognosis. there are many differences between pmc and clinically apparent papillary thyroid carcinoma. also, there are some pmc case reports with unusual metastasis and aggressive courses. prognostic factors are age, size and morp...

the association of squamous cell carcinoma of the larynx with thyroid papillary carcinoma is an unusual finding. from 2004 to 2011, approximately 250 patients underwent laryngectomies due to squamous cell carcinoma of the larynx at the otolaryngology department of khalili hospital, affiliated with shiraz university of medical sciences, shiraz, iran. in three patients, synchronous occurrence of ...

ectopic thyroid tissue results from abnormal embryologic development and migration of the thyroid gland. true malignant transformation in ectopic thyroid tissue is extremely rare and is always diagnosed after surgical excision of the lesion by pathology examinations. there are well-documented cases of ectopic thyroid cancer while primary tumoral lesion occurs in the orthotopic thyroid, but only...

the coexistence of medullary thyroid carcinoma (mtc), papillary thyroid carcinoma (ptc) and parathyroid adenoma is an uncommon clinical entity. here, we report a case of mtc, ptc, and parathyroid adenoma diagnosed incidentally on a routine physical examination of the neck for the work-up of diabetes. the patient had neither symptoms of hypercalcemia nor those related to mtc and ptc.

The prevalence of BRAFT1799A mutation in papillary thyroid carcinomas (PTCs) displays a marked age association: relatively high in adults and exceedingly low in childhood. We report a case of a 12-year-old Japanese female with PTC, the only one case that harbored BRAFT1799A mutation in a series of 46 childhood thyroid cancer tissues. On histology, the findings were so atypical that pathologists...
