Maffucci syndrome is a rare condition with multiple enchondromas and hemangiomas. Fewer than 200 cases have been reported in the United States. There is a high predilection for neoplastic changes, and PET/CT has an important role in detecting these changes.

Multiple benign osteolytic lesions are very hard to differentiate from disseminated bone metastasis. Whole-body bone scintigraphy (WBBS) with technetium-99m methylene diphosphonate (Tc-99m MDP) demonstrates multiple lesions with increased uptake in any bone involved. Even combined with medical history and multiple imaging results, such as MRI and CT, the clinical diagnosis of metastasis lesion ...

Benign tumours of the bone are not cancerous and would not metastasise to other regions of the body. However, they can occur in any part of the skeleton, and can still be dangerous as they may grow and compress healthy bone tissue. There are several types of benign tumours that can be classified by the type of matrix that the tumour cells produce; such as bone, cartilage, fibrous tissue, fat or...

We report a case of a 56-year old man with chronic pain in both knees for several years. This patient had already undergone surgery on his left knee in 2002 after an x-ray showed multiple lytic and well margined lesions in the distal femur and proximal tibia with ground-glass matrix, involving Hoffa's fat pad and the patellar ligament. Histology was consistent with an enchondroma. The most rece...

Note Ollier disease was first described by Louis Ollier, a French surgeon in early 1800s. The disorder is characterized by the presence of at least three enchondromas. Ollier disease manifests early in childhood and affects both sexes equally. Lesions are distributed unilaterally. In Ollier disease, enchondromas form in the medulla of mainly long bones and it is now clear that Ollier disease is...

Eight cases of fibrous dysplasia having enchondroma-like areas (fibrocartilaginous dysplasia) are reported. Four patients were male, four were female. The patients' ages ranged from 8 to 18 years (mean = 11.3 years). In seven cases, the lesions were located at the proximal femur while one was at the tibial diaphysis. Histologically, large, well-defined, sharply demarcated islands of hyaline car...

Chest wall abscess is a rare manifestation of childhood tuberculosis. We report a case of a tuberculous chest wall abscess in a 4-year-old healthy girl who had received Bacillus Calmette-Guerin (BCG) vaccination at birth. She developed a localized anterior chest wall mass, which was initially mistaken for enchondroma on the chest radiograph. Pathologic examination of the biopsy specimen reveale...

Dysspondyloenchondromatosis (DSC) is a rare skeletal dysplasia that has currently been classified into the group of spondylometaphyseal dysplasias. To date, only 12 affected individuals have been reported. All cases are sporadic, and the etiology remains unknown. Distinctive features of DSC are anisospondyly and enchondroma-like lesions in the metaphyseal and diaphyseal portions of the long tub...

CASE A 13-year-old boy presented to the ski clinic following a fall and a possible twisting of his right knee. He was not able to bear any weight on his right leg and was experiencing pain in the medial aspect of his right knee. His past medical and surgical histories were unremarkable and he was otherwise in good health. Physical examination revealed no ecchymosis or effusion. He had moderate ...
