Phases of Wound Repair

Phases of Wound Repair

Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

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 II

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Area of Science:

Dermatology
Pediatric Pathology

Background:

Pilomatrixoma is a common benign skin tumor originating from hair follicle matrix cells.
The bullous variant of pilomatrixoma is exceptionally rare, with limited documented cases.

Observation:

A 10-year-old boy presented with a rapidly growing, erythematous, bullous nodule on his neck.
The lesion appeared subsequent to a traumatic event.

Findings:

The case represents a rare bullous variant of pilomatrixoma.
The etiology remains unclear, but mechanical trauma is a suspected trigger for this subtype.

Implications:

This case expands the clinical spectrum of pilomatrixoma.
Further investigation into the role of trauma in bullous pilomatrixoma development is warranted.
