What is tumoral calcinosis?
Tumoral calcinosis (TC) is a rare clinical and histopathologic syndrome characterized by calcium salt deposition in different peri-articular soft tissue regions[1,2].
Is tumoral calcinosis benign?
Tumoral calcinosis is a rare and benign hereditary tumor-like periarticular calcium deposit. It is painless and it is found commonly around large joints such as hip, shoulder and elbow.
What is familial tumoral calcinosis?
Hyperphosphatemic familial tumoral calcinosis (HFTC) is a condition characterized by an increase in the levels of phosphate in the blood (hyperphosphatemia) and abnormal deposits of phosphate and calcium (calcinosis) in the body’s tissues.
How is calcinosis diagnosed?
Diagnosis of calcinosis cutis
- blood tests to see if your calcium and phosphate levels are abnormally high, to look for markers for lupus and possible tumors, and to rule out abnormal parathyroid and vitamin D levels.
- metabolic tests to rule out kidney problems.
What causes tumoral calcinosis?
Tumoral calcinosis may be genetic, the result of prior traumatic injury, or the result of a metabolic derangement, most commonly chronic renal failure, which accounts for approximately 23% of cases. Onset is typically in the second decade of life, with a reported increased frequency in African Americans.
What causes familial tumoral calcinosis?
FGF23 in Hyperphosphatemic Familial Tumoral Calcinosis HFTC is caused by either a deficiency of active, intact FGF23 or a defect in its signaling (Table 1). The disease is typically inherited in an autosomal recessive pattern (7).
Is calcium deposit a tumor?
The name indicates calcinosis (calcium deposition) which resembles tumor (like a new growth). They are not true neoplasms – they don’t have dividing cells. They are just deposition of inorganic calcium with serum exudate. Children and adolescents (6 to 25 years) are the most commonly affected.
What is the treatment for calcinosis?
Diltiazem is the most commonly used treatment for calcinosis cutis. It decreases the amount of calcium that enters cells and macrophages of the damaged tissues. High doses at 2 mg/kg/d to 4 mg/kg/d are necessary for therapeutic response.
What is the difference between dystrophic calcification and metastatic calcification?
Metastatic calcification with hypercalcemia occurs when calcium deposits in previously normal tissue whereas dystrophic calcification occurs in previously damaged tissue.
What is MRI calcification?
In MRI, calcification appears with various signal intensities on conventional spin echo (SE) T1 or T2 weighted images (3, 4, 5), which makes it difficult to identify definitively as calcium. In gradient-echo acquisitions, calcifications usually appear as hypointense and cannot be differentiated from hemorrhage.
What is the pathophysiology of tumor calcinosis?
Tumoral calcinosis is a rare familial condition characterized by painless, periarticular masses. The term should be strictly used to refer to a disease caused by a hereditary metabolic dysfunction of phosphate regulation associated with massive periarticular calcinosis and should not be used to refer to soft-tissue calcification in general.
Is tumoral calcinosis hereditary?
On the contrary, tumoral calcinosis is a rare familial disease. Unfortunately, the term tumoral calcinosis has been liberally and imprecisely used to describe any massive collection of periarticular calcification, although this term actually refers to a hereditary condition associated with massive periarticular calcification.
What does tumoral calcinosis look like on a CT scan?
Tumoral calcinosis has a typical appearance on plain radiographs with amorphous and multilobulated (“cloud-like”) calcification located in a periarticular distribution. CT there is no erosion or osseous destruction by the adjacent soft-tissue masses which is another distinguishing finding of tumoral calcinosis from other pathologies
What are the most common locations of tumor calcinosis on radiographs?
The most common locations are (in descending order of frequency) 2: Tumoral calcinosis has a typical appearance on plain radiographs with amorphous and multilobulated (“cloud-like”) calcification located in a periarticular distribution.
