Bone exostosis has long been described in the literature, appearing in most cases as a torus palatinus or mandibularis. These two variations are relatively common and affect approximately 30% of the world's population. Incidence is even higher when human skulls are examined post mortem, indicating that in some cases the exostosis is small and cannot be seen under the soft tissue. Removal of an ...

Exostosis in external auditory canal is common among surfers. Common symptoms are decreased hearing or loss of hearing, ear infection, and/or plugging sensation. Repeated exposure to cold water is a key clinical history to suspect this condition. Based on symptoms and existence of infection, surgical removal of the exostosis is recommended.

UNLABELLED INTRODUCTION Although palsy of the long thoracic nerve is the classical pathogenesis of winging scapula, it may also be caused by osteochondroma. This rare etiopathology has previously been described in pediatric patients, but it is seldom observed in adults. CASE PRESENTATION We describe three cases of static scapular winging with pain on movement.Case 1 is a Caucasian woman ag...

Audiometric survey and endoscopic study of the external auditory canal were performed on a group of 31 professional divers, all of whom had experienced frequent exposure to dysbaric conditions. The results are as follows. 1) Over 40% had exostosis of the external auditory canal. There was no relationship between the incidence of the exostosis and the length of their occupational career as a div...

Osteochondromas and subungual exostosis are commonly misunderstood conditions. They are widely used synonymously. However a detailed review of literature tells us that subungual exostosis is in fact a rare variant of osteochondroma. This peculiar tumor is relatively uncommon; it has not been much remarked on the recent years. We report a case of subungual exostosis of the hallux in an 18 year o...

Introduction Hereditary multiple exostosis (HME) is a skeletal disorder characterized by the presence of numerous bony outgrowths (osteochondromas or exostoses) that develop next to the growth plates of all the long bones (Solomon 1963). The most striking clinical feature of HME is the numerous cartilage-capped exostoses, which are associated with the entire skeleton. Skeletal surveys suggest t...

A 27 year old man presented with two bony lumps in the fifth toe of the right foot. Both lumps were present from early childhood. The lump in the toe was painful while both lumps were bony and the lump in the metatarsal was diagnosed to be an exostosis of the bone while the phalangeal lump was diagnosed to be an enchondroma. It is a known association to have multiple exostosis with diaphyseal b...

UNLABELLED Osteochondroma, which is also known as exostosis, is the most common benign bone tumor. Although foot and hand surgeons frequently encounter the subungual exostosis, exostoses commonly localize to other areas of the skeleton as well. In this review, we describe the clinical and diagnostic imaging characteristics of benign bone tumors and, in particular, the osteochondroma and its sur...
