The thyroid has a conspicuously distinctive architecture consisting of numerous follicles of various sizes, lined by cuboidal epithelium and filled with
This study was therefore undertaken to examine the presence and characteristics of TCs in normal human thyroid stromal tissue through an inte- grated morphologic approach featuring light
The clinical manifestations vary with thyroid function and with the size and location of the goiter. The evaluation of the adult with goiter will be reviewed here. The treatment of goiter in adults
Each thyroid follicle is surrounded by thin connective tissue stroma rich in fenestrated capillaries (along with the sympathetic nerves that innervate
The thyroid function tests, and thyroglobulin were within normal limits. An ultrasound guided fine needle aspiration cytology (FNAc) was performed from the thyroid nodule on the lower left lobe. The FNA
Thyroid nodules and thyroid abnormalities are common findings in the general population. Ultrasonography is the most important imaging tool for
We have studied seven cases of papillary thyroid carcinoma with prominent myofibroblastic stroma, including six men and one woman aged 20–65 years (mean age = 44).
Introduction Riedel fibrosing thyroiditis is a rare disease characterized by chronic inflammation and fibrosis of the thyroid gland. It is also known as Riedel struma, ligneous struma, or
The follicules of the thyroid gland are surrounded by connective tissue stroma, which is not well inves tigated. To fulfill our aim we studied ultrastructurally the operative tissue from Struma nodosa patients.
This article covers the anatomy of the thyroid gland, including functions, hormones, and clinical aspects. Learn this topic now at Kenhub!
If the ectopic thyroid tissue is functioning (5-20% of cases), struma ovarii might cause hyperthyroidism or even thyreotoxicosis, therefore resulting in palpitations, hypertension, tremor, anxiety, weight loss
RESULTS 3.1. Immunohistochemical identification of TCs in the human thyroid stroma The analysis of haematoxylin and eosin‐stained thyroid sections allowed both to exclude any
3.2 Ultrastructural identification of TCs in the human thyroid stroma Transmission electron microscopy confirmed the existence of stromal cells ultrastructurally
Thyroid nodules — even the occasional cancerous ones — are treatable. Here''s what you need to know about thyroid nodules and how concerned you should be
It is mostly the protein thyroglobulin (pink) and bound thyroid hormones (triiodothyronine and tetraiodothyronine (or thyroxin)). The clear space around the colloid is a shrinkage artifact.
The patient underwent surgery, and the microscopic appearance revealed a diffuse infiltration of thyroid stroma by mature adipose tissue with associated amyloid deposition.
Struma ovarii is a rare ovarian tumor containing thyroid tissue, often associated with hyperthyroidism or malignancy. Learn about its diagnosis and management.
Reticular fibers extend from the septa and form a network supporting the thyroid parenchyma. It is composed of follicles, which appear in histological sections round to oval of
We report struma ovarii in a case that had hyperthyroidism and was treated with laparoscopic tumor resection. A 40-year-old Japanese woman presented with tachycardia, finger
While epithelial structure and functions have been substantially investigated in many organs, the mesenchymal elements have received less attention. Compared with follicular epithelial cells, there
Struma ovarii is an extremely rare monodermal teratoma of the ovaries that produce thyroid hormone. We report a case of unexplained hyperthyroidism in a female patient that was found to have struma
The stroma in fine-needle aspiration biopsy (FNAB) of thyroid lesions has not been well investigated. We studied 256 consecutive cases of thyroid FNAB prepared
