Hyperthyroidism II: Pathophysiology

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...

The Parathyroid Glands

The Parathyroid Glands

The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...

Hypothyroidism II: Pathophysiology

Hypothyroidism II: Pathophysiology

Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...

Graves Disease II: Pathophysiology

Graves Disease II: Pathophysiology

Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...

Cellular Adaptation IV: Dysplasia and Metaplasia

Cellular Adaptation IV: Dysplasia and Metaplasia

DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...

Classification of Epithelial Tissues: Glandular Epithelium

Classification of Epithelial Tissues: Glandular Epithelium

The glandular epithelium is made of one or more epithelial cells modified to synthesize and secrete chemical substances. Glandular epithelia can be classified based on cell number. Unicellular glands have individual secretory cells scattered across the epithelial monolayer. In contrast, multicellular glands consist of a hollow tubular duct attached to the cluster of secretory cells located in the deep pockets.
Multicellular glands are formed during early development when epithelial budding...

Summary

Histological variants of papillary thyroid cancer (PTC) significantly impact patient prognosis. Identifying aggressive patterns like the tall cell variant is crucial for tailored treatment and improved outcomes.

Background:

Papillary thyroid cancer (PTC) staging relies on the Tumor-node-metastasis (TNM) system.
Histopathological patterns and variants of PTC influence patient prognosis and therapeutic strategies.

Purpose of the Study:

To review clinical presentation, recurrence, and mortality across frequent PTC histological patterns.
To compare the prognostic implications of various PTC variants, including tall cell and follicular variants.

Main Methods:

Retrospective review of clinical data for patients with different PTC histological patterns.
Analysis of prognostic factors including cancer recurrence and cancer-specific mortality.
Evaluation of specific variants: follicular variant (FVPTC), tall cell, diffuse sclerosing, etc.

Main Results:

Tall cell variant of PTC is aggressive with a poor prognosis, potentially due to high Muc 1 and type IV collagenase expression.
Follicular variant of PTC (FVPTC) shows better survival and less invasion compared to classical PTC.
Diffuse sclerosing variant is rare, aggressive, predominantly in young patients, and challenging to diagnose pre-operatively.

Conclusions:

Histological variants of PTC are critical for predicting cancer recurrence beyond TNM staging.
High-risk PTC histological patterns necessitate aggressive follow-up and adjuvant therapies.
Understanding variant-specific prognoses aids in optimizing treatment and patient management.
