The term fibrosis refers to the formation of fibrous tissue that may or may not be associated with tissue healing.
Some of the different types of fibrosis include the following:
Lung fibrosis or pulmonary fibrosis
Pulmonary fibrosis may occur as a result of long standing infections such as tuberculosis or pneumonia. The condition can also be caused by exposure to occupational hazards such as coal dust or the genetic condition cystic fibrosis.
Cirrhosis refers to the scar tissue and nodules that replace liver tissue and disrupt liver function. The condition is usually caused by alcoholism, fatty liver disease, hepatitis B or hepatitis C.
Areas of the heart that have become damaged due to myocardial infarction may undergo fibrosis.
This form of fibrosis is characterized by calcified fibrosis of the lymph nodes, which can block respiratory channels and blood vessels.
Retroperitoneal cavity fibrosis
This refers to fibrosis of the soft tissue in the retroperitoneum, which contains the aorta, kidneys and numerous other structures.
Bone marrow fibrosis
Myelofibrosis is scarring in the bone marrow that prevents the normal production of blood cells in the bone marrow.
Scar tissue that forms on the skin in response to injury is referred to as a keloid.
Scleroderma or systemic sclerosis
Scleroderma is an autoimmune disease of the connective tissue that primarily affects the skin but can also involve other organs such as the kidneys, heart and lungs.
Some examples of the effects fibrosis can have on the body are given below:
- Fibrosis of the joints may lead to stiffness and pain in the knees, plavix canada wrists and hips
- Fibrosis of the tendons may lead to conditions such as Dupuytren's contracture, which can cause deformity of the hands and fingers
- The shoulder capsule may be affected leading to adhesive capsulitis and frozen shoulder
- Fibrosis that involves the soft tissue of the penis is referred to as Peyronie's disease
|Type||Most common location(s)||Circumscription||Cellularity||Vascularity and nature of vessels||Appearance of collagen||Elastic fibers|
|Nuchal fibroma||Nuchal region||No||Very low||Very low||Bundles of fibers||Scant|
|Collagenous fibroma||Shoulder girdle, extremities||Yes, by macroscopic appearance, but microscopically infiltrative||Increased but generally low||Low||Scant or absent||Amorphous|
|Fibroma of tendon sheath||Distal extremities, especially the hand||Yes||Low to high||Moderate to high, with some slitlike vessels||Amorphous||Absent|
|Scar||Variable||Variable||Low to high||Variable||Amorphous||Scant to absent|
|Elastofibroma||Subscapular chest wall||No||Low to moderate||Low||Amorphous||Abundant and abnormal|
|Desmoid-type fibromatosis||Abdominal wall, shoulder girdle||Yes, by macroscopic appearance, but microscopically infiltrative||Moderate||Moderate, mildly dilated||Amorphous||Absent|
|Keloid||Upper part of back, deltoid, presternal, ear lobes||No||Some fibroblasts||Low||Amorphous thick eosinophilic bundles||Scant or Absent|
