BACKGROUND Morbus Ollier is characterized by the presence of multiple enchondromas (ie, benign intraosseous cartilaginous lesions). Although their manifestation in the limb bones is well described, only a few cases with ear, nose, and throat (ENT) involvement, primarily arising from the skull, have been reported. The malignant transformation toward slowly growing low-grade chondrosarcomas is th...

Tibial dyschondroplasia (TD) is a metabolic cartilage disease in poultry the natural etiology of which is not known. In the absence of biomarkers to monitor the initiation and progression of the naturally occurring disease, experimentally induced TD can provide a suitable venue to study the mechanism of its pathogenesis. Therefore, the objective of this study was to establish a streamlined expe...

The first experiment was a central composite rotatable design with calculated calcium levels of 6.2, 7.0, 9.0, 11.0, and 11.8 g/kg diet and total phosphorus levels of 5.2, 6.0, 8.0, 10.0, and 10.8 g/kg diet (2.8 g phytin-P/kg by analysis). This design involved three replicates for each rotatable point and fifteen replicates of the central point. The second experiment was a 4 x 4 factorial desig...

BACKGROUND Synovial chondromatosis is characterized by cartilaginous metaplasia in synovial tissues. Extra-articular tenosynovial chondromatosis is considered to be an anatomical counterpart of articular synovial chondromatosis. Extra-articular tenosynovial chondromatosis occurs preferentially in the hand, although its frequency is low. RESULTS We report three cases of extra-articular tenosyn...

Leg health has been an important component of broiler welfare and of the economy of broiler production for many decades and includes a wide range of leg disorders leading to locomotion problems (e.g. Thorp, 1994; SCAHAW, 2000; Bradshaw et al., 2002). This article will focus on five leg health traits recorded within the Aviagen Ltd (Newbridge, UK) breeding programme, namely (1) long bones deform...

Osteochondrosis/osteoarthrosis (OC/OA) are common terms for various joint pathologies that occur in pigs. Pathologies that may contribute to these disorders have been described, but the primary cause(s) remain unknown. We hypothesised that as OC has some similarities to dyschondroplasia, which involves a failure of growth plate chondrocytes to fully differentiate and hypertrophy, treatment with...

Osteochondromatosis is a condition in which multiple benign, cartilage-capped tumors arise from the surface of bones formed by endochondral ossification. The current report describes the presence of 4 prominent exophytic masses, measuring between 4 and 13 cm in diameter, arising from the surface of the ribs, and located within the thoracic cavity, in a 2-year-old female domestic pig (Sus scrofa...

Osteochondroma is a common benign tumor of the axial skeleton, especially in the distal metaphysis of the femur and the proximal metaphysis of the tibia, that can occur on the facial skeleton (albeit rarely). Osteochondroma is differentiated from chondroma, osteochondromatosis and osteoma. Osteochondroma shows an irregular radiopaque lesion and chondromatic area surrounded by the osteoma. When ...

We report a case of a 75-year-old female with bilateral thigh pain for several years secondary to soft tissue calcification. Massive calcinosis of the soft tissues is a unique, but not uncommon, radiographic finding. On the contrary, tumoral calcinosis is a rare familial disease. The term tumoral calcinosis has been overly used to describe any massive collection of periarticular calcification. ...

Synovial osteochondromatosis is a benign proliferative disorder with metaplasia of the synovial membrane that affects the fibroblasts of the synovial joints, tendons and bursae. In literature, there are few descriptions of synovial osteochondromatosis of the elbow. The objective of this article was to report a case of synovial osteochondromatosis of the elbow in a patient aged 32, basketball at...
