title: Distribution of insulin-like growth factors in condylar hyperplasia.
abstract: Condylar hyperplasia (CH) is a local overgrowth of the condylar process of the temporomandibular joint (TMJ) of unknown etiology. Probably, growth factors like the insulin-like growth factors (IGFs) are involved in its pathogenesis. Specimens from 12 patients were investigated histologically and immunohistochemically to obtain the distribution of the IGFs-I and -II and the IGF1 receptor. The results revealed juvenile and adult subtypes. While generally IGF-II could only be detected weakly, in the juvenile cases strong immunostaining for IGF-I in cartilage and bone supposes an influence on pathological growth processes.
