Caput mandibulae accessorium.
The presented anomaly consists of a doubled mandibular condylus in a boy aged 5.5 years. We report this case because of its rare localisation, shape, size and microscopic pattern. It represents a doubled articular process arising from the mandibular processus coronoideus. From the morphologic view the finding is very exceptional. We failed to find any similar case in the literature available. The findings of doubled articular processes (condylus bifidus) previously quoted are of different origin. In this case it was obviously disorder in the differentiation of the mandible within the period when the mandibular ramus basis was formed by the secondary cartilage.
