Abnormal formation of a bodily structure or tissue, usually bone, that may occur in any part of the body. Several types are well-defined diseases in humans. In the most common, epiphyseal dysplasia, the ends of children's bones (epiphyses) grow and harden very slowly; dwarfism often results (sometimes only in the legs), and degenerative joint disease usually develops by middle age. Large dogs bred for narrow hips may have hip dysplasia, with abnormalities involving the head of the thighbone and the hip socket
Any abnormal development of tissues or organs In pathology, alteration in size, shape and organization of adult cells
abnormal development (of organs or cells) or an abnormal structure resulting from such growth
An abnormality of cells of one tissue and the morphologic result(s) of that abnormality (An example is achondroplasia where abnormal formation of cartilage tissue results in disproportionate dwarfing)
Bronchopulmonary dysplasia (BPD; formerly Chronic Lung Disease of Infancy) is a chronic lung disorder that is most common among children who were born prematurely, with low birthweights and who received prolonged mechanical ventilation to treat respiratory distress syndrome
Hip dysplasia is a hereditary disease that, in its more severe form, can eventually cause crippling lameness and painful arthritis of the joints. It is caused by a combination of genetic and environmental factors. It can be found in many animals and occasionally in humans, but is most commonly associated with dogs, and is common in many dog breeds, particularly the larger breeds
a disturbance in which bone that is undergoing lysis is replaced by an abnormal proliferation of fibrous tissue resulting in bone lesions or skin lesions
Canine hip dysplasia affects millions of dogs each year and can result in debilitating degenerative joint disease of the hip It is estimated that more than 50% of the most popular large breed dogs will show x-ray evidence of canine hip dysplasia Many will suffer from osteoarthritis, pain, and lameness, costing owners and breeders millions of collars in veterinary care, shortened work longevity, and reduced performance
