Necrotizing arteritis with giant cells associated with haemolytic anaemia
Journal of Clinical Pathology
|September 1, 1965
Summary
A rare case of necrotizing arteritis with giant cells was identified in a 74-year-old male with cold agglutinin hemolytic anemia. This autoimmune-related vasculitis presents unique features not fully aligning with existing giant cell arteritis classifications.
Area of Science:
- Pathology
- Immunology
- Vascular Medicine
Background:
- Necrotizing arteritis, particularly giant cell arteritis, is a significant cause of vascular inflammation.
- Hemolytic anemia associated with cold agglutinins suggests an autoimmune process.
- Understanding rare vasculitis presentations is crucial for accurate diagnosis and treatment.
Observation:
- A 74-year-old male presented with severe hemolytic anemia linked to cold agglutinins.
- Post-mortem examination revealed necrotizing arteritis with giant cells affecting major arteries (aorta, pulmonary, coronary) and smaller vessels (coronary, splenic, renal arterioles).
Findings:
- The observed necrotizing arteritis exhibited features overlapping with giant cell arteritis but did not fit established diagnostic criteria.
- The co-occurrence of cold agglutinin hemolytic anemia points towards a potential autoimmune etiology for the vasculitis.
Implications:
- This case highlights a potential variant of autoimmune-related necrotizing arteritis.
- Further research into the immunopathogenesis of such vasculitis is warranted.
- Recognition of this presentation may improve diagnostic accuracy in complex cases of vasculitis and autoimmune hemolytic anemia.

01:16Necrosis
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
01:25Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
01:16Cellular Injury IV: Necrosis
Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...
01:26Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
