Skin Diseases and Disorders

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...

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...

Reticular Dermis

Reticular Dermis

The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Pulmonary Tuberculosis III

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Staphylococcal Skin Infections

Staphylococcal Skin Infections

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...

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.

Summary

Sarcoidosis commonly affects the skin, with specific lesions like scar infiltrates often overlooked despite their diagnostic value. Cutaneous sarcoidosis aids in histological diagnosis and can indicate other organ involvement.

Area of Science:

Dermatology
Immunology
Pathology

Context:

Sarcoidosis is a multisystem inflammatory disease with variable cutaneous manifestations.
Skin involvement occurs in 10-30% of sarcoidosis cases, with lesion prevalence differing across populations.
Cutaneous lesions are classified as specific or nonspecific, with specific types including nodules, plaques, lupus pernio, subcutaneous nodules, and scar infiltrates.

Purpose:

To highlight the diagnostic significance of cutaneous sarcoidosis, particularly overlooked lesions like scar infiltrates.
To emphasize the role of skin biopsies in establishing a histological diagnosis of sarcoidosis.
To underscore the association between specific cutaneous lesions and systemic sarcoidosis involvement.

Summary:

Cutaneous sarcoidosis presents diverse lesions, with specific types like scar infiltrates being crucial for diagnosis but frequently missed due to subtle presentation.

Histopathological examination of skin lesions provides a reliable method for diagnosing sarcoidosis.

Certain skin manifestations of sarcoidosis correlate with involvement of other organs, aiding in comprehensive patient assessment.

Impact:

Increased recognition of subtle cutaneous lesions, such as scar infiltrates, can improve early diagnosis of sarcoidosis.
Understanding the link between skin and systemic involvement enhances clinical management strategies for sarcoidosis patients.
Facilitates earlier and more accurate diagnosis through accessible skin biopsies, potentially improving patient outcomes.
