Thyroglossal duct carcinomas: light and electron microscopic studies. 1986

S G Ronan, and E Deutsch, and L Ghosh

Two cases of papillary carcinoma arising in thyroglossal duct cysts are reported. Electron microscopic studies were done on both cases and similar ultrastructural features were noted. When compared with a case of papillary adenocarcinoma arising in the thyroid gland proper, no difference was seen both at the light microscopic and ultrastructural levels.

UI	MeSH Term	Description	Entries
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D002291	Carcinoma, Papillary	A malignant neoplasm characterized by the formation of numerous, irregular, finger-like projections of fibrous stroma that is covered with a surface layer of neoplastic epithelial cells. (Stedman, 25th ed)	Carcinomas, Papillary,Papillary Carcinoma,Papillary Carcinomas
D002294	Carcinoma, Squamous Cell	A carcinoma derived from stratified SQUAMOUS EPITHELIAL CELLS. It may also occur in sites where glandular or columnar epithelium is normally present.

D000231	Adenocarcinoma, Papillary	An adenocarcinoma containing finger-like processes of vascular connective tissue covered by neoplastic epithelium, projecting into cysts or the cavity of glands or follicles. It occurs most frequently in the ovary and thyroid gland. (Stedman, 25th ed)	Adenocarcinomas, Papillary,Papillary Adenocarcinoma,Papillary Adenocarcinomas

D013955	Thyroglossal Cyst	A cyst in the neck caused by persistence of portions of, or by lack of closure of, the primitive thyroglossal duct.

D013961	Thyroid Gland	A highly vascularized endocrine gland consisting of two lobes joined by a thin band of tissue with one lobe on each side of the TRACHEA. It secretes THYROID HORMONES from the follicular cells and CALCITONIN from the parafollicular cells thereby regulating METABOLISM and CALCIUM level in blood, respectively.
