“…Several, but rare, complications have also been noted in some patients, most commonly being the development of osteosarcoma (81%), fibrosarcoma (14%), chondrosarcoma (3%), malignant fibrous histiocytoma (1%), malignant giant cell tumour and lymphosarcoma (0.5%) 14 15. No treatment was given to the patient in our Dental College; he was referred to a higher centre for better management and treatment.…”

Paget's disease with craniofacial and skeletal bone involvement

Paget's disease is a metabolic disorder of bone caused due to defect in the remodelling process and is very common in western countries but is very rare in Asians and Africans. It was first described by a British scientist Sir James Paget in 1877. It can be monostotic or polyostotic depending on the number of bones involved. It most commonly affects older people of more than 50 years. Disease involvement can be symptomatic or asymptomatic depending on the extent of the disease process. Diagnosis of Paget's disease can be made by raised serum alkaline phosphatase levels, radiological examination and by radioisotope bone scans.

“…Skeletal abnormalities in TSC include cyst-like lesions, hyperostosis of the inner table of the calvaria, osteosclerotic changes ( Figure 11 ), periosteal new bone formation, cystic changes in the phalanges, and scoliosis ( 3 ) . These bone abnormalities can also be seen in several other diaseases ( 17 - 22 ) , and only in the presence of changes in other organs that fulfill TSC criteria can be associated with the complex. Retinal hamartomas are present in about 40-50% of patients with TSC.…”

Imaging of tuberous sclerosis complex: a pictorial review

et al. 2017

Tuberous sclerosis complex (TSC) is a genetically determined hamartomatous neurocutaneous disease with high phenotypic variability. TSC is characterized by widespread hamartomas and benign, or rarely malignant, neoplasms distributed in several organs throughout the body, especially in the brain, skin, retina, kidney, heart, and lung. Common manifestations include cortical tubers, subependymal nodules, white matter abnormalities, retinal abnormalities, cardiac rhabdomyoma, lymphangioleiomyomatosis, renal angiomyolipoma, and skin lesions. The wide range of organs affected by the disease implies that TSC1 and TSC2 genes play important roles in the regulation of cell proliferation and differentiation. Although recent advances in treatment have improved morbidity, the prognosis remains quite poor and nearly 40% of patients die by the age of 35 years. Imaging is important in the evaluation of TSC because of its role not only in presumptive diagnosis, but also in defining the full extent of involvement. This information allows a better understanding of the behavioural phenotype, as related to lesion location. Imaging also contributes to treatment planning. This pictorial review describes common and uncommon imaging manifestations of TSC.

“…Although osseous lymphoma was classically considered in the differential diagnosis of an ivory vertebra, this is a relatively rare occurrence. 33,34 The mixed sclerotic-lytic type is more common in secondary lymphomas and after treatment. 30 However, radiographic findings may be very subtle even in the presence of aggressive appearance on other imaging modalities (►Fig.…”

Ewing's sarcoma (ES) is a rare, highly malignant anaplastic stem cell tumor. Histologically, the tumor consists of uniform densely packed small monomorphic cells with round nuclei. The typical appearance at hematoxylin and eosin (H&E) staining is small blue round cells without any matrix formation. On conventional radiography, ES typically presents as a permeative lesion in the diaphysis of a long bone in a child. A large soft tissue component is another characteristic feature, best depicted by magnetic resonance imaging.Primary osseous lymphomas are most commonly highly malignant B-cell lymphomas. At H&E histologic staining, the tumor stroma consists of diffuse round-cell infiltrates that resembles the appearance of ES. Although there is no typical imaging appearance of an osseous lymphoma, it should be considered in an adult presenting with a Lodwick grade II or III lesion in the metaphysis or diaphysis of a large long bone, the pelvis, or the vertebral column. Histologic confirmation is mandatory.
