INTRODUCTION: Medullary carcinoma is a rare malignant neuroendocrine tumor of the thyroid gland. (MTC) has no specific clinical symptoms. Due to absence symptoms, disease usually diagnosed at stage metastatic lesions regional lymph nodes, and sometimes, internal organs. The five- ten-year survival after detection distant metastases 25% 10%, respectively. OBJECTIVE: To analyze available foreign ...

Aims Medullary carcinoma is an uncommon colorectal tumour which appears poorly differentiated histologically. Consequently, it may be confused with adenocarcinoma not otherwise specified (NOS). The principal aim of this study was to review a large series cancers resected at National Health Service (NHS) Teaching Hospital determine how often medullary carcinomas were misclassified . Secondary ai...

High calcitonin levels noted on a totally healthy 49-year-old man participating in a calcitonin control project led to a presumptive diagnosis of medullary carcinoma. Complete thyroid studies augmented by selective catheterization and quantitative calcitonin studies confirmed the clinical impression of medullary carcinoma. Surgery was recommended and a total thyroidectomy was performed. On gros...

in females, the most common cancer is breast carcinoma in which squamous cell carcinoma (scc) is a rare type of malignancy. histologically, infiltrating ductal carcinoma is the most common type and lobular, mucinous, and medullary types have lower incidence. pure scc of the breast can originate from the skin, nipple, or epithelium of a deep‑seated dermoid cyst or squamous metaplasia on chronic ...

AIMS To show that medullary carcinomas of the thyroid are morphologically indistinguishable from gut carcinoids: the value of histochemistry in their identification and differential diagnosis from metastatic carcinoid tumours to the thyroid and some follicular cell neoplasms. METHODS 15 thyroid medullary carcinomas with features of gut carcinoids were histochemically studied for the presence ...

BACKGROUND Mixed medullary-follicular thyroid carcinoma denotes a rare and heterogeneous group of tumors displaying morphological and immunophenotypical features of both origins within the same lesion. METHOD We report a case of a 41-year-old woman with a lump in the right side of the neck, increasing in pain and size over several weeks. Serum levels of calcitonine (1140 ng/L) and carcinoembr...

This case report is the fourth case documented of a patient with synchronous Follicular, Papillary, and Medullary Thyroid Carcinoma. There have been several case series in the last two decades that include either concurrent papillary-medullary or follicular-medullary thyroid carcinoma, but only three cases documented for all three of these types of thyroid carcinomas occurring in the same patie...
