Cutaneous lesions caused by mechanical injury
European Journal of Dermatology : EJD
|June 13, 2015
Summary
Mechanical injury causes two types of skin lesions: folliculitis mechanica and acne vulgaris flare-ups. This study redefines these conditions, offering new insights into their clinical and histological characteristics.
Area of Science:
- Dermatology
- Pathophysiology
Background:
- The term 'acne mechanica' has historically encompassed diverse cutaneous lesions resulting from mechanical injury.
- This study aimed to redefine the spectrum of mechanically induced skin lesions by analyzing their clinical and histological features.
Observation:
- Analysis of 135 published cases and clinical data revealed two primary types of mechanically induced inflammatory skin lesions.
- The first type, proposed as 'folliculitis mechanica', presents with inflammatory papules, open comedones, or lacks comedones.
- The second type involves acne vulgaris flare-ups in susceptible areas, exhibiting typical acne lesions.
Findings:
- Mechanical factors induce distinct inflammatory cutaneous lesions.
- Folliculitis mechanica is characterized by inflammatory papules and/or comedones, or a lack thereof.
- Acne mechanica is reclassified as a flare-up of acne vulgaris.
Implications:
- The proposed term 'folliculitis mechanica' offers a more precise classification for specific mechanically induced lesions.
- Understanding these distinctions aids in targeted treatment strategies.
- Treatment may involve topical agents for barrier and microbiome support, alongside conventional acne medications for flare-ups.

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.

Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

6.6K
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.

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...

01:19Clinical Applications of Epidermal Stem Cells
3.4K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

01:19Pigmentation
5.0K
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...
