Summary
Allergic contact dermatitis (ACD) is a delayed hypersensitivity reaction diagnosed by patch testing. Consider ACD in dermatitis cases unresponsive to treatment or with new symptoms.
Area of Science:
- Immunology
- Dermatology
Background:
- Allergic contact dermatitis (ACD) is a Type IV delayed hypersensitivity.
- Patch testing is the gold standard for diagnosing ACD.
- Prevalence of positive patch tests in patients with suspected ACD varies widely (27-95.6%).
Purpose of the Study:
- To highlight the diagnostic value of patch testing for ACD.
- To discuss the complex relationship between ACD and atopic dermatitis (AD).
- To emphasize considering ACD in refractory or evolving dermatitis cases.
Main Methods:
- Review of diagnostic standards for ACD.
- Analysis of prevalence data for positive patch tests.
- Discussion of the differential diagnosis between ACD and AD.
Main Results:
- Patch testing demonstrates a high prevalence of positive results in referred patients.
- The association between ACD and AD is not clearly defined in existing literature.
- ACD is a crucial consideration for dermatitis that does not improve with standard treatments.
Conclusions:
- Patch testing remains essential for ACD diagnosis.
- ACD should be investigated in patients with persistent or spreading dermatitis, especially when standard therapies fail.
- The differential diagnosis between ACD and AD requires careful clinical evaluation.

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...

Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
