Summary
Cutaneous lupus erythematosus (LE) presents varied skin lesions influenced by UV light and drugs. Subacute cutaneous LE with anti-Ro/SS-A antibodies indicates a good prognosis, with individualized treatment focusing on severity.
Area of Science:
- Dermatology
- Immunology
- Rheumatology
Background:
- Cutaneous manifestations are frequent and diverse in lupus erythematosus (LE).
- Environmental factors like ultraviolet light and certain drugs are key triggers.
- A classification system aids in defining cutaneous LE subtypes.
Purpose of the Study:
- To detail the varied clinical presentations of cutaneous lupus erythematosus.
- To discuss differential diagnoses based on disease stage.
- To highlight the prognostic significance of specific immunogenetic markers.
Main Methods:
- Review of clinical, histologic, photobiologic, serologic, and immunogenetic findings.
- Analysis of 25 years of worldwide clinical experience.
- Evaluation of treatment strategies for cutaneous LE.
Main Results:
- Cutaneous LE subtypes vary considerably during disease evolution.
- Subacute cutaneous LE with anti-Ro/SS-A antibodies signifies a homogeneous, good-prognosis immunogenetic subphenotype.
- Most patients do not require systemic immunosuppression; biologics offer hope for severe cases.
Conclusions:
- Individualized treatment is crucial for cutaneous lupus erythematosus.
- Understanding disease subtypes and prognostic markers improves patient management.
- Advances in biologics provide new therapeutic options for severe cutaneous LE.

01:23Skin 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...

01:30Skin 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.

01:14Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

01:19Pigmentation
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
01:29Autoimmune Disorders
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.
