Subungual exostosis arises underneath the nail plate, originating from the underlying bone. The characteristic appearance of this disorder may occasionally mimic a wide variety of tumors, including subungual verrucae, endochondroma, fibroma, or amelanotic melanoma. With such a wide variety of similar-appearing tumors, optimal treatment of this disorder clearly lies in proper recognition and tre...

By P. N. RAY, b.a., m.b., f.r.c.s. (Eng.) (Surgeon, Ccirmichael Medical College Hospitals, and Additional Surgeon, General Hospital, Howrah) This rare condition is known under a multiplicity of names, e.g., multiple cartilaginous exostoses, hereditary multiple exostoses, etc. The patient, a Hindu male child aged 12, complained of swelling around both the knees and the left ankle with hard nodul...

The curious affection known as "subungual exostosis" appears to have been scientifically described for the first time by Dupuytren, who discriminated cases as early as 1817; hence it is also often called " Dupuytren's exostosis." In studying the natural history of this condition, one cannot help noticing the great frequency of its occurrence as compared with other ossiform skeletal outgrowths; ...

Osteochondroma of the spine is a rare condition. It may present in solitary form or with multiple exostoses or hereditary multiple exostoses. In this article, we report a 22-year-old male case who was diagnosed with cervical osteochondroma, originating from the third and fourth cervical vertebra.

Although, osteochondroma is the most common bone tumor, metacarpal involvement is quite uncommon and usually accompanies multiple hereditary exostoses. Herein, we described a patient with solitary ostechondroma of the fourth metacarpal bone, and discussed the differential diagnosis of bony spurs that can be seen in hand.

BACKGROUND Multiple hereditary exostoses (MHE) is characterized by multiple benign projections of bone capped by cartilage, most numerous in metaphyses of long bones. HME are usually inherited in autosomal dominant mode, chief genes EXT1 and EXT2. METHODS Two MHE patients were identified from clinic and enrolled in genetic study, complete coding regions of EXT1 and EXT2, including intron/exon...

Osteochondroma is the most common benign bone tumor and usually occurs in the metaphyseal region of the long bones. This tumor takes the form of a cartilage-capped bony outgrowth on the surface of the bone. The vast majority (85%) of osteochondromas present as solitary, nonhereditary lesions. Approximately 15% of osteochondromas occur as multiple lesions in the context of hereditary multiple os...
