Summary
Immunoglobulin G4-related hypophysitis is a rare inflammatory pituitary disorder. This study reviews 115 cases, highlighting clinical, imaging, and pathological findings for better diagnosis and management of this underdiagnosed condition.
Area of Science:
- Endocrinology
- Immunology
- Pathology
Background:
- Hypophysitis is a rare inflammatory pituitary disorder with various classifications.
- Immunoglobulin G4-related disease (IgG4-RD) is a systemic fibro-inflammatory condition.
- The prevalence of both hypophysitis and IgG4-RD may be underestimated.
Purpose of the Study:
- To present a case of biopsy-proven IgG4-related hypophysitis.
- To review clinical, laboratory, imaging, and pathological findings of IgG4-related hypophysitis.
- To analyze therapeutic management and prognosis of published cases.
Main Methods:
- Case presentation of an Iranian patient with IgG4-related hypophysitis.
- Systematic literature review of 115 published cases of hypophysitis secondary to IgG4-RD.
- Analysis of clinical characteristics, laboratory results, imaging findings, pathology, treatment, and outcomes.
Main Results:
- IgG4-related hypophysitis presents with diverse clinical and imaging features.
- Histopathological examination reveals characteristic IgG4-positive plasma cell infiltration.
- Treatment strategies include corticosteroids and/or immunosuppressants, with varying prognoses.
Conclusions:
- IgG4-related hypophysitis is an important differential diagnosis for pituitary inflammation.
- Early diagnosis and appropriate management are crucial for favorable outcomes.
- Further research is needed to elucidate the pathogenesis and optimize treatment protocols.

Adrenal Gland Disorders
2.4K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Hypersensitivities
3.9K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Hypothalamic-Pituitary Axis
63.7K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

The Pituitary Gland
8.3K
The pituitary is a small endocrine organ in the sphenoid bone under the hypothalamus. Primarily, the pituitary in adults has two distinct anatomical and functional regions— the anterior and posterior lobes. During human fetal development, a third pituitary gland region called the pars intermedia atrophies and disappears. However, some of its cells migrate and exist adjacent to the anterior pituitary in adults.

The Parathyroid Glands
3.3K
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...

Gastritis-II: Pathophysiology
818
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
