Skin Cancer

Skin Cancer

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...

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...

Summary

Discoid lupus erythematosus (DLE) can be distinguished from other cutaneous lupus subtypes by lesion location, characteristic damage, and lack of high-titer Ro/SSA antibodies. Histopathology and immunoreactant deposition are less effective differentiators.

Background:

Discoid lupus erythematosus (DLE) is a subtype of cutaneous lupus erythematosus.
Accurate classification criteria are needed to differentiate DLE from other lupus subtypes and mimics.
Existing classification criteria require refinement based on current evidence.

Purpose of the Study:

To review the literature for features distinguishing DLE from other cutaneous lupus erythematosus (CLE) subtypes.
To identify clinical, histopathologic, and serologic features with supporting data for DLE classification.
To highlight research gaps for future classification criteria development.

Main Methods:

Literature review using Ovid MEDLINE database.
Search for studies reporting criteria for distinguishing DLE from other CLE subtypes.
Analysis of clinical, histopathologic, and serologic features for diagnostic utility.

Main Results:

Lesion localization, characteristic damage features, and absence of high-titer Ro/SSA antibodies are most effective in differentiating DLE.
Histopathologic features and class of immunoreactant deposition appear less helpful for distinguishing DLE.
Identified gaps in the literature regarding definitive diagnostic markers for DLE.

Conclusions:

Clinical features, particularly lesion location and damage characteristics, alongside serologic findings (absence of high-titer Ro/SSA antibodies), are key for differentiating DLE.
Histopathology and immunoreactant deposition are less reliable for distinguishing DLE from other CLE subtypes.
Further research is needed to refine classification criteria for DLE, addressing identified literature gaps.
