Goiter

Goiter

Goiter refers to an abnormal enlargement of the thyroid gland that may appear as a diffuse goiter (uniform enlargement) or nodular (single or multiple nodules). Functionally, it is classified as nontoxic (normal/low hormone levels) or toxic (excess hormone production).PathophysiologyDiffuse thyroid enlargement typically results from prolonged stimulation by thyroid-stimulating hormone (TSH) or TSH-like agents, commonly seen in hypothyroidism or iodine deficiency. In contrast, in hyperthyroid...

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...

Hyperthyroidism I: Introduction

Hyperthyroidism I: Introduction

Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...

Graves' Disease I: Introduction

Graves' Disease I: Introduction

Graves' disease is an autoimmune disorder that causes hyperthyroidism, or overactivity of the thyroid gland. It results from autoantibodies called thyroid-stimulating immunoglobulins (TSIs), which bind to thyroid-stimulating hormone (TSH) receptors, leading to overstimulation of hormone production and a hypermetabolic state.EtiologyAlthough considered idiopathic, Graves’ disease has well-established contributing factors. There is a strong genetic component, with increased prevalence in...

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 III: Hyperplasia

Cellular Adaptation III: Hyperplasia

Hyperplasia is an increase in the number of cells in a tissue or organ due to enhanced cell division. It is an adaptive, controlled response to stimuli such as injury, hormones, or stress, involving mitosis to produce genetically identical cells and support tissue repair and regeneration.Tissue CapacityCertain tissues, including the epidermis, intestinal epithelium, bone marrow, and fibroblasts, have a high potential for hyperplasia. Others, such as bone, cartilage, and smooth muscle, show...

[Sporadic C-cell hyperplasia associated with multinodular goiter].

Summary

Sporadic C cell hyperplasia, often diagnosed via calcitonin screening, requires further study. Current evidence suggests it does not alter clinical management, unlike familial forms linked to MEN2 syndromes.

Area of Science:

Endocrinology
Thyroid Pathology

Background:

C cell hyperplasia can be familial (MEN2 syndromes) or sporadic, often linked to other thyroid conditions.
The prevalence and biological significance of sporadic C cell hyperplasia remain under investigation.
Increased diagnosis of sporadic C cell hyperplasia is linked to routine calcitonin screening for early medullary thyroid carcinoma detection.

Observation:

A 47-year-old female with nodular goiter presented with slightly elevated serum calcitonin and a positive pentagastrin test.
Histological examination confirmed C cell hyperplasia in the absence of medullary carcinoma.
Morphological features indicated a sporadic, physiologic form, distinct from neoplastic C cell hyperplasia in MEN2.

Findings:

The study identified sporadic C cell hyperplasia in a patient with nodular goiter and elevated calcitonin.

Calcitonin immunohistochemistry confirmed C cell hyperplasia without evidence of malignancy.

The observed case aligns with a sporadic, non-neoplastic presentation.

Implications:

The progression of sporadic C cell hyperplasia to medullary carcinoma requires further research.
Diagnosis of sporadic C cell hyperplasia does not currently necessitate changes in clinical or therapeutic approaches.
Further studies are needed to define the prevalence and clinical relevance of sporadic C cell hyperplasia.
