Insights

A persistent skin eruption in a patient with common variable immunodeficiency resolved with intravenous immunoglobulin therapy. This case highlights sterile granulomatous lesions in primary immunodeficiency.

Area of Science:

  • Dermatology
  • Immunology
  • Pathology

Background:

  • Common variable immunodeficiency (CVID) is a primary immunodeficiency characterized by low immunoglobulin levels and impaired B-cell function.
  • Patients with CVID are susceptible to recurrent infections and autoimmune phenomena.
  • Unusual skin manifestations, such as sterile granulomatous lesions, can occur in CVID.

Observation:

  • A 64-year-old male with CVID presented with a persistent papulonodular ulcerative skin eruption on his right leg.
  • Histopathology revealed a chronic inflammatory infiltrate with central necrosis and palisading granuloma.
  • Microbiological studies were negative for any infectious agents.

Findings:

  • The skin lesions showed a progressive resolution following treatment with intravenous immunoglobulins (IVIg).
  • Complete clearing of the eruption was observed after 10 months of IVIg therapy.
  • The clinicopathological features suggest a sterile granulomatous process.

Implications:

  • Intravenous immunoglobulin therapy can be effective in managing sterile granulomatous skin lesions associated with primary immunodeficiencies like CVID.
  • This case underscores the importance of considering non-infectious inflammatory conditions in the differential diagnosis of skin lesions in immunocompromised patients.
  • Further research into the pathogenesis and optimal management of sterile granulomatous lesions in primary immunodeficiencies is warranted.

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...
Hypersensitivity Reactions: Cytolytic Reactions01:01

Hypersensitivity Reactions: Cytolytic Reactions

Type II hypersensitivity involves IgG and IgM antibodies targeting cell surface antigens, leading to cell destruction. This can occur through complement activation, antibody-dependent cell-mediated cytotoxicity (ADCC), or acting as opsonins for phagocytosis. When excessive, these reactions cause significant tissue damage.Drug-induced hemolytic anemia is a common example, where drugs like penicillin or cephalosporins bind to red blood cells, forming drug-protein complexes. These complexes...
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
Hypersensitivity Reactions: Immune-Complex Reactions01:19

Hypersensitivity Reactions: Immune-Complex Reactions

Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
