We present two cases of HFTC successfully managed with combination acetazolamide (ACTZ) and sevelamer carbonate. [bone-abstracts.org]

Case presentation Familial tumoral calcinosis was present in two members of a Han Chinese family, namely, the son and daughter. [jmedicalcasereports.biomedcentral.com]

Classification of these conditions often presents many nosological challenges, since underlying etiologies and pathogenetics are often not known. [howlingpixel.com]

In the present study, we describe a patient of Northern European origin displaying typical features of HFTC. [nature.com]

There are many conditions which present with a similar clinicoradiological picture like 2. [myslide.es]

• Blurred Vision

  One had symptomatic sudden onset of blurred vision attributed to choroidal neovascularization secondary to angioid streaks 14 years after the initial diagnosis of HFTC [ McGrath et al 2010 ]. [ncbi.nlm.nih.gov]

This finding emphasizes the need for thorough hematologic workup, including marrow studies, in potential sibling donors especially when they lack a genetic marker for familial disease. [haematologica.org]

• Muscle Calcification

Of note, there are no long-term treatment data. [ncbi.nlm.nih.gov]

Only surgical treatment was performed in both patients with satisfactory prognosis. Conclusion This is the first report of Chinese familial tumoral calcinosis. The etiopathogenisis and treatment are discussed. [jmedicalcasereports.biomedcentral.com]

Various methods have been proposed for the treatment of tumoral calcinosis. Conservative treatment includes antacids, low calciumephosphate diet, acetazolamide and newer agents like vinpocetine, a calcium channel blocker [16,17]. [myslide.es]

Although the pathogenesis of the calcification process in TC is still controversial, surgical removal is the mainstay treatment with a satisfactory prognosis. [jmedicalcasereports.biomedcentral.com]

A classification for tumoral calcinosis is devised that outlines potential pathogenetic mechanisms and predicts response to therapy and prognosis. [scienceopen.com]

The prognosis of the disease is good although patients often undergo many surgical procedures to remove the calcified tumours [20]. Normophosphataemic FTC is less prevalent than the hyperphosphataemic variant [19,26]. [plasticsurgerykey.com]

Classification of these conditions often presents many nosological challenges, since underlying etiologies and pathogenetics are often not known. [howlingpixel.com]

Moreover, there is evidence that FTC is genetically heterogeneous and another gene might be implicated in the etiology of FTC. [grantome.com]

ETIOLOGY, PATHOGENESIS AND CLASSIFICATION Etiology of TC remains uncertain despite the several theories that have been proposed. [wjgnet.com]

They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]

Introduction Idiopathic tumoral calcinosis is a rare benign clinical condition of unknown etiology presenting as periarticular soft tissue calcifications. Symptoms and complications due to this condition are rarely seen. [myslide.es]

Pathophysiology Deficiency of or resistance to FGF23 leads to hyperphosphatemia resulting in increased renal phosphate reabsorption and elevated or inappropriately normal 1,25D production, which promotes gastrointestinal absorption of phosphorus and calcium [ncbi.nlm.nih.gov]

Further research, including identification of specific molecules transported by ABCC6, is necessary for development of global, pathophysiology-related approaches to treat this currently intractable disorder. [pxe.org]

The destabilizing nature of these mutations provides new insight into the pathophysiology of TC and exemplifies the physiological importance of FGF23 in phosphate and vitamin D metabolism. [scienceopen.com]

We hypothesize that ppGalNAc-T3 deficiency is associated with a decrease in extracellular inorganic pyrophosphate (ePPi), which at normal levels prevents basic calcium phosphate crystal depositions in joints and other tissues. [grantome.com]

Once the diagnosis is established, complete surgical excision is the only option for cure and prevention of recurrence. References 1. Pakasa NM, Kalengayi RM. [archintsurg.org]

No treatment regimen appears to consistently or universally decrease lesion size or prevent progression or recurrence of lesions after surgery. Tumoral calcinosis Low-phosphate diet. [ncbi.nlm.nih.gov]

Conclusion Primary idiopathic Tumoural Calcinosis is still a disease of unknown cause but complete surgical resection is an effective method of management of this disese and it prevents recurrence. [oapublishinglondon.com]
