Introduction. Although fractures of humeral shaft show excellent results with conservative management, nonunion does occur. Case Report. We bring forth the case of a young male with a 1.5-year-old hypertrophic nonunion of the humerus mimicking an enchondroma. The initial X-ray images of the patient appeared to be an enchondroma, which only on further evaluation and histopathological analysis wa...

BACKGROUND Enchondroma, a subtype of chondroma, originates from the medullary cavity of the bone and produces an expansile growth pattern. Enchondroma located in the spine is rare and a few cases of large thoracic enchondroma have been reported. The authors document a rare case of large enchondroma in the thoracic spine of a 49-year-old woman, and discuss its clinical, radiological and histopat...

BACKGROUND An enchondroma is a rather common benign tumour of bone that originates from cartilage.The course is usually benign but they have a tendency to recur and are sometimes invasive, especially when developing in long bones. The aim of the study was to analyze the manifestations and methods of treatment as well as to assess the results of surgical treatment in patients with enchondroma. ...

Introduction. Enchondroma protuberans is an extremely rare benign cartilaginous bone tumor. We report the first case report of enchondroma protuberans in the forearm. Presentation of Case. We report a case of enchondroma protuberans originating in the left ulnar bone of a young woman. A 20-year-old female referred to our hospital complaining of progressive sustained left forearm pain with a rad...

background and aims. well-differentiated chondrosarcoma and enchondroma are similar in histopathologic aspects; therefore, special methods should be used to make a distinction between these benign and malignant tumors. the aim of this study was to evaluate the efficacy of a histopathologic method in the long-term follow-up for differentiating these lesions. materials and methods. the medical re...

Background: Enchondroma is the most frequent bone tumor of the hand, but chondrosarcoma is rare at this location. There is a high possibility of correct diagnosis of enchondroma and differentiating from its malignant counterpart by precise clinical and radiologic assessment without biopsy, a subject of debate in the literature. At the present study we substantially investigate this problem, in ...

Chondrosarcoma is the third most common primary bone cancer, requiring surgical resection. However, differentiation of low-grade chondrosarcoma (grade 1) from enchondroma that is benign and only requires regular follow-up is one of the most frequent diagnostic dilemmas facing orthopedic oncologists in clinical management. Although multiple techniques are applied to make the distinction, immunoh...
