Abstract

Introduction: Calcium deposition in the skin has been termed as calcinosis cutis. Tumoral calcinosis is idiopathic form of calcinosis cutis. Etiology of idiopathic calcinosis cutis is unknown. It is characterized by periarticular deposition of amorphous calcium salts around large joints. Our diligent search through literature could not find any consensus on the etiopathogenesis and treatment modalities for tumoral calcinosis.
Materials and Methods: A retrospective study of seven patients of tumoral calcinosis treated with complete surgical excision over a period of 1 year was done. Demographic details were compiled. Routine blood investigations were performed. All patients underwent radiographs and magnetic resonance imaging (MRI) scans of involved part. We did not perform computed tomography (CT) or bone scan in any of our patients. All seven patients underwent surgery and were followed up till 2 years.
Results: In our study, five were female and two were male patients ranging from 31 to 76 years. Size of swelling varied from 2 to 15 cm. Most common location was hip. Serum calcium, phosphorus, and alkaline phosphatase were normal in all patients. Radiographs showed well-outlined periarticular cluster of calcifications in the soft tissues around joint. MRI revealed round to oval multiple cystic lesions around the affected region, but not involving the joint.
Conclusion: Tumoral calcinosis is always the diagnosis of exclusion. It can be normophosphatemic or hypophosphatemic subtype. Large joints are more commonly affected. One can rely on radiographs for diagnosis. MRI for knowing exact location of lesion, its relationship with adjacent structures and planning of surgery is advocated. Complete surgical excision is the only optimum treatment of tumoral calcinosis.
Keywords: Amorphous calcium phosphate, hyperphosphatemia, X-ray film, hip joint, calcinosis, magnetic resonance imaging.

Abstract

Introduction: Parosteal lipoma is a rare type of lipoma. Usually, asymptomatic and affecting mainly adults aged over 40.
Case Report: We report two cases localized in the lower limb. The first happened in a man presenting a painless swelling of the fibula, represented by a well-defined fatty tissue lesion. The second case concerned women presenting an asymmetry of the calf, represented by a well-defined mass composed of fatty tissue. The lesions were resected from surrounding soft tissues and underlying periosteum. The diagnosis was confirmed by histology.
Conclusion: Parosteal lipoma has the same characteristics of computed tomography (CT) and magnetic resonance imaging (MRI) as subcutaneous fat. The identification of fat is best performed with CT or MRI. Its recognition is mandatory to optimize clinical management including diagnosis, biopsy, and treatment.
Keywords: Deep-seated lipoma, Computed tomography, Magnetic resonance imaging.

Abstract

Giant cell tumor(GCT) of bone is a tumor of giant cell proliferation that usually affects men and women in the thirdand fourthdecades. Typical cases have straight-forward imaging appearances. Atypical cases may resemble many other benign and sometimes malignant lesions. Plain radiographs and magnetic resonance imaging (MRI) are the mainstay of diagnosis, followed by biopsy and histology.Positron emission tomography/computed tomography (CT) has a limited role to play.Aneurysmal bone cyst transformation within GCTs is known. This may change the imaging appearance. GCTs may be multifocal, locally aggressive, and may metastasize to nodes and lungs.Treatment with drugs like denosumab also changes the appearance on radiographs and MRI. Post-operative imaging can be a challenge, and picking up recurrence also requires high-quality radiographs, MRIs, and CT scans.
Keywords: Giant cell tumor, giant cell tumor, bone neoplasm, computed tomography scan, magnetic resonance  imaging, plain radiograph.
