Calcinosis

Calcinosis is a medical condition characterized by the deposition of calcium salts in soft tissues of the body. This abnormal calcification can occur in various parts of the body, including the skin, muscles, tendons, and blood vessels. It is a rare condition that can be caused by a variety of underlying diseases or can occur as an idiopathic or primary condition.

Types of Calcinosis:

  1. Dystrophic Calcinosis: Dystrophic calcinosis occurs due to the deposition of calcium in tissues that have been damaged or have undergone necrosis. It is commonly seen in conditions such as dermatomyositis, scleroderma, and systemic lupus erythematosus (SLE). In these conditions, the skin or other tissues become damaged, and calcium deposits occur as a result of the body’s attempt to repair the damaged tissues.
  2. Metastatic Calcinosis: Metastatic calcinosis occurs when there is an abnormality in calcium metabolism in the body, leading to the deposition of calcium salts in soft tissues. This can be seen in conditions such as hyperparathyroidism, renal failure, and vitamin D toxicity.
  3. Iatrogenic Calcinosis: Iatrogenic calcinosis occurs as a result of medical treatments such as long-term use of calcium supplements, injections of calcium-containing substances, and certain medications such as warfarin.
  4. Idiopathic Calcinosis: Idiopathic calcinosis refers to calcification that occurs without any underlying disease or condition. This is a rare form of calcinosis, and the exact cause is unknown.

Causes

Causes of calcinosis in detail.

  1. Connective Tissue Disorders: Connective tissue disorders, such as systemic sclerosis, dermatomyositis, and lupus, are the most common causes of calcinosis. These conditions are characterized by the abnormal production and deposition of collagen, which can lead to the formation of calcium deposits in the affected tissues.
  2. Vitamin D Overdose: Vitamin D is essential for bone health and the absorption of calcium. However, taking too much vitamin D supplements can lead to hypercalcemia, which can result in calcinosis.
  3. Chronic Kidney Disease: Chronic kidney disease can cause calcium buildup in the body due to a malfunction of the kidneys’ ability to regulate calcium levels.
  4. Hyperparathyroidism: Hyperparathyroidism is a condition in which the parathyroid glands produce too much parathyroid hormone, which can lead to increased calcium levels and calcinosis.
  5. Hypervitaminosis A: Hypervitaminosis A, or excessive vitamin A intake, can cause calcification of soft tissues, including the skin, joints, and internal organs.
  6. Tumoral Calcinosis: Tumoral calcinosis is a rare genetic disorder that causes the formation of large calcium deposits in the soft tissues, particularly around the joints.
  7. Idiopathic Calcinosis: Idiopathic calcinosis refers to cases where the cause of calcinosis is unknown. This type of calcinosis may be associated with certain autoimmune disorders.
  8. Sarcoidosis: Sarcoidosis is a condition in which small nodules or lumps form in various organs of the body. These nodules can sometimes contain calcium deposits.
  9. CREST Syndrome: CREST syndrome is a subtype of systemic sclerosis that affects the skin, blood vessels, and internal organs. It can also cause calcinosis.
  10. Wilson’s Disease: Wilson’s disease is a rare genetic disorder that causes the accumulation of copper in the body. In severe cases, this can lead to calcification of soft tissues.
  11. Chronic Graft-Versus-Host Disease: Chronic graft-versus-host disease is a complication that can occur after a bone marrow or stem cell transplant. It can cause the formation of calcium deposits in the skin and other tissues.
  12. Milk-Alkali Syndrome: Milk-alkali syndrome is a condition that occurs when a person consumes large amounts of calcium and alkali-containing products, such as milk and antacids. This can result in high calcium levels and calcinosis.
  13. Hypoparathyroidism: Hypoparathyroidism is a condition in which the parathyroid glands do not produce enough parathyroid hormone, which can lead to low calcium levels and calcinosis.
  14. Tertiary Hyperparathyroidism: Tertiary hyperparathyroidism occurs when the parathyroid glands produce too much parathyroid hormone in response to long-term low calcium levels. This can lead to calcinosis.
  15. Paget’s Disease: Paget’s disease is a condition in which the bone tissue breaks down and reforms abnormally. This can lead to high calcium levels and calcification of soft tissues.
  16. Myeloma: Myeloma is a cancer of the plasma cells, which are responsible for producing antibodies. High levels of calcium in the blood can

Symptoms

Symptoms can vary depending on the underlying cause of the disorder.

  1. Skin lesions: One of the most common symptoms of calcinosis is the development of hard, white or yellowish bumps on the skin. These bumps can be painful and may be located on any part of the body, but are most commonly found on the hands, feet, and face.
