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...

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:

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...

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...

Acne Infection

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Sexually Transmitted Infections

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Summary

This summary is machine-generated.

Lichen scrofulosorum, a rare skin manifestation of tuberculosis, can be misdiagnosed. Prompt antitubercular therapy effectively cleared skin lesions in a patient with tuberculous lymphadenitis.

Background:

Tuberculosis (TB) is a prevalent infectious disease globally.
Cutaneous tuberculosis, or tuberculid, is uncommon and prone to misdiagnosis.
Lichen scrofulosorum is a rare tuberculid affecting children and young adults, sometimes associated with systemic TB.

Observation:

This report details a case of lichen scrofulosorum in a young adult.
The patient also presented with tuberculous lymphadenitis.
Skin lesions showed a rapid response to treatment.

Findings:

Antitubercular therapy led to complete clearance of the lichen scrofulosorum skin lesions.
Diagnosis was challenging due to an inconclusive lymph node biopsy.
Tissue culture confirmed tuberculosis after a 4-week delay.

Implications:

Early identification of cutaneous manifestations like lichen scrofulosorum is crucial for timely TB diagnosis.
Skin findings can guide diagnosis when traditional methods like biopsy are equivocal.
Effective treatment of systemic TB leads to resolution of associated skin lesions.
