Hyperphosphatemic familial tumoral calcinosis (HFTC) is a rare, autosomal recessive genetic disease. This disease is characterized by the progressive calcification of soft tissues leading to symptoms of pressure and hyperphosphatemia but normal concentrations of serum calcium with or without an elevation of 1,25-dihydroxyvitamin D3 levels.HFTC is caused by loss-of-function mutations in the GALNT3, FGF23 or KL genes. Here, we identified two novel mutations in the GALNT3 gene in a Chinese family with HFTC. Identification of a novel genotype in HFTC provides clues for understanding the phenotype-genotype relationships in HFTC and may assist not only in the clinical diagnosis of HFTC but also in the interpretation of the genetic information used for prenatal diagnosis and genetic counseling...

BACKGROUND: In-stent neoatherosclerosis is characterized by the delayed appearance of markers of atheroma in the subintima, but the pathophysiology underlying this new disease entity remains unclear. METHODS AND RESULTS: We collected 20 human coronary artery stents by removal from explanted hearts. The mean duration of stent implantation was 34 months. In all samples, neoatherosclerosis was detected, particularly in peristrut areas. It consisted of foam cells and cholesterol clefts, with or without calcification, associated with neovascularization...

Spinal epidural space is a real anatomic space located outside the dura mater and within the spinal canal extending from foramen magnum to sacrum. Important contents of this space are epidural fat, spinal nerves, epidural veins and arteries. Due to close proximity of posterior epidural space to spinal cord and spinal nerves, the lesions present with symptoms of radiculopathy and/or myelopathy. In this pictorial essay, detailed anatomy of the posterior epidural space, pathologies affecting it along with imaging pearls to accurately diagnose them are discussed...

Radiopaque lesions of the jawbones are frequently encountered in dental radiographs. A variety of conditions such as chronic inflammation, soft tissue calcifications, fibrosseous lesions, odontogenic tumors, and bone neoplasms can manifest as radiopaque lesions on the jawbones. These radiopaque lesions are often difficult to distinguish from each other, hence making the formulation of differential diagnosis challenging. A thorough patient's history and clinical examination supplemented by appropriate investigations will enable the clinician in narrowing down the differential diagnosis and to identify the condition accurately...

Soft tissue calcification is associated with aging, common conditions such as diabetes or hypercholesterolemia and with certain genetic disorders. ABCC6 is an efflux transporter primarily expressed in liver facilitating the release of ATP from hepatocytes. Within the liver vasculature, ATP is converted into pyrophosphate (PPi), a major inhibitor of ectopic calcification. ABCC6 mutations thus lead to reduced plasma PPi levels resulting in the calcification disorder pseudoxanthoma elasticum (PXE) and some cases of generalized arterial calcification of infancy (GACI)...

BACKGROUND: Fibrosing mediastinitis (FM) is a rare disease. FM is thought to be related to prior granulomatous mediastinal infection, such as histoplasmosis or tuberculosis. The majority of cases have been reported in endemic regions for histoplasmosis. The characteristics of cases of FM in China, where the prevalence of tuberculosis is high, have not been reported. We analyzed the clinical, imaging, and bronchoscopic features of Chinese patients with FM to promote awareness of this disease...

The use of autologous fat grafting in breast reconstruction still requires optimization. Fat survival and calcification are the main issues that affect the outcomes of the procedure. In this study, a cell-based therapy utilizing laminin-alginate beads (LABs) as carriers was proposed to promote cell survival and adipogenesis by providing short-term physical support and facilitate nutrient diffusion of the implants. Laminin-modified alginate beads were fabricated by immobilizing laminin onto ring-opened alginate, used to encapsulate 3T3-L1 preadipocytes, and evaluated in vitro and in vivo...

The paper describes a case of parosteal lipoma of the temporal bone, by simultaneously involving the parotid salivary gland. Computed tomography performed in a 48-year-old man showed that in the area of the posterior edge of the glenoid fossa of the right temporal bone there was a massive (1.5×1.7×0.9-cm) exostosis extending down from the skull base. The exostosis was surrounded by a 3.5×3.6×5.3 soft tissue mass that was located in the projection of the right parotid salivary gland with a capsule and minor calcifications...

Oral manifestations of severe secondary hyperparathyroidism include maxillary and mandibular deformities, brown tumors, dental abnormalities, and metastatic calcification of soft tissues. We report on a chronic hemodialysis (HD) woman with severe, uncontrolled secondary hyperparathyroidism and a painful, nontender mass in the floor of her mouth. The most likely clinical diagnosis was a bone tumoral lesion of the oral cavity, secondary to renal osteodystrophy. Unexpectedly, pathological examination showed characteristic features of ossifying fibroma (OF) of the jaw, a rare, benign fibroosseous lesion characterized by the replacement of normal bone by collagen and fibroblasts containing varying amounts of mineralized substance...

We present the case of an 83-year-old man who had painful swelling of right knee for 6 months. Radiographs showed a large intra-articular soft-tissue mass with small calcifications, whereas MRI detected a multilobulated intra-articular tumor with bone erosions at the distal femur. Histopathology of ultrasound-guided biopsy specimen of the synovial mass revealed it to be a poorly differentiated metastatic carcinoma. Abdominal computed tomography with intravenous contrast medium administration found a heterogeneously enhancing large right renal mass with calcifications, which was shown to be a renal cell carcinoma on histopathology...

A 40-year-old woman was referred to our hospital with right lower back pain as the chief complaint. Contrast-enhanced computed tomography (CT) showed a partially-solid tumor within a cyst measuring approximately 6 cm in diameter in the right renal hilum. The solid part was enhanced in the early phase and contrast medium was washed out earlier in the solid part than in the parenchyma in the equilibrium phase. Plain CT revealed partial cyst wall calcification. A soft tissue shadow approximately 10 mm in diameter in the dorsal inferior vena cava at the upper pole of the kidney and a solid tumor adjacent to the iliopsoas muscle and the kidney were detected...

Primary hyperparathyroidism (pHPT) is a condition caused by excessive and uncontrolled secretion of parathyroid hormone. The classical presenting symptoms in primary hyperparathyroidism are renal stones, hypercalcemic crisis, soft tissue calcifications, and cystic bone disease. Although most cases of pHPT are detected early and before symptomatic lesions appear, some patients may present late in the course of their disease. In this report, we present a patient with extensive parenchymal calcifications forming a cast of the right kidney which is called as "putty kidney" with Brown tumor located in the pubic ramus...

BACKGROUND: Point-of-care ultrasound has an increasing role in characterizing soft-tissue infections and has been described previously in the evaluation of necrotizing fasciitis (NF). The identification of air within the soft tissues can be very suggestive of NF in the correct clinical context. CASE REPORT: A 78-year-old male presented to the emergency department with extensive lower-extremity redness and edema. A point-of-care ultrasound revealed hyperechoic areas within the soft tissues consistent with air, and the patient was taken to surgery and found to have NF...

A large proportion of patients with retroperitoneal fibrosis (RPF) have been labelled as having idiopathic RPF historically. Recent reports of a subset of these patients having a fibro-inflammatory condition with characteristic histology and good response to therapy has helped in renewed understanding of an old disease. A 40 year old man presented with vague abdominal discomfort of 5 months duration. Ultrasound examination revealed soft tissue thickening with calcification over lower abdominal aorta. CT scan characterized the lesion as a retroperitoneal mass encasing the aorta with an associated lesion in upper pole of left kidney...

Synovial sarcoma (SS) is a soft tissue sarcoma of the extremities developing in young adults that has rarely been reported in the orbit. SS is associated with a unique translocation, resulting in an SYT-SSX fusion gene. We analyze seven published periocular cases, together with the current one, to gain a better appreciation of the features of the tumor in this location and to compare the findings with those derived from non-ophthalmic studies. A 31-year-old woman developed an inferior orbital mass after experiencing periorbital and hemifacial pain for more than a decade...

BACKGROUND: Tumoral calcinosis is a rare manifestation of extraskeletal calcification, featuring large calcified cystic masses in the periarticular regions of large joints. In chronic kidney disease (CKD), this disorder is thought to evolve through a chronically elevated calcium-phosphorus solubility product leading to calcium precipitation in soft tissue. Treating tumoral calcinosis in these patients involves interventions to lower the calcium-phosphorus product such as reduction in vitamin D therapy and intensive hemodialysis regimens...
