Thyroglossal duct cysts are the most frequently encountered congenital neck masses having a malignancy rate of 1%. The most common malignant form is papillary thyroid carcinoma. Synchronous papillary thyroid carcinoma developing in the thyroglossal duct cyst is rarely seen. Synchronized papillary carcinoma can be described as a multifocal tumor or a metastatic lesion on a thyroglossal duct cyst...

With fewer than 40 cases described in the otolaryngology literature, mixed medullary papillary thyroid carcinoma represents a rare but phenotypically distinct tumor. While isolated medullary carcinoma may be admixed with normal follicular structures, true mixed carcinoma displays morphological and immunological characteristics of medullary and papillary carcinoma within a single lesion. We repo...

CONTEXT According to the literature, laryngeal papillary carcinoma is rare and has a benign prognosis. CASE REPORT In this report we present a surprising case with nodal metastasis at the time of diagnosis. Computed tomography showed infiltration of the lesion and metastatic lymph nodes. The resected specimen was submitted to histopathological study that confirmed the diagnosis of papillary s...

BACKGROUND Metastatic papillary thyroid carcinoma typically appears in local lymph nodes. Skin metastases are rare. PURPOSE A man with progressive metastatic papillary thyroid carcinoma who developed a cutaneous metastasis on his nose is described. The clinical manifestations of metastatic papillary thyroid carcinoma to skin are reviewed. METHODS PubMed was used to search the following term...

Malignant melanoma can be successfully treated when it is identified in its early stages, but the disease is associated with a poor prognosis when it is detected in an advanced stage. Papillary thyroid carcinoma is a thyroid cancer that has a good prognosis. The present study reports a rare case of malignant melanoma and papillary thyroid carcinoma that were diagnosed concurrently and treated s...

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...

Is aggressive digital papillary adenocarcinoma (ADPA) really aggressive? Does it only occur at digital location? Does it always have microscopic papillary features? Is it really adenocarcinoma? Let’s us address these questions one by one. Is ADPA aggressive? From the term, namely, aggressive digital papillary adenocarcinoma, one would interpret this as high grade malignant tumor with grim progn...

BACKGROUND Many studies have reported an increased risk of developing a second primary malignancy (SPM) of the breast in women treated for thyroid cancer. In this study, we investigated several potential risk factors for this association. The aim of this retrospective cohort study was to identify a subgroup of women surgically treated for papillary thyroid cancer that may benefit from more care...

Intraductal/intracystic papillary carcinoma (IPC) of the breast is defined as a malignant non-invasive papillary tumor arising from the ductal-lobular system. Based on the presence of myoepithelial cells in the cystic wall, IPC is distinguished from encapsulated papillary carcinoma (EPC). Here, we report a case of an intracystic apocrine papillary tumor in the breast of a 49-year-old woman. His...
