Abstract
Osteochondromas are the most common benign tumors of the bone. Mainly these lesions affect the long-bone metaphysis and usually are asymptomatic. When complications develop from these lesions, then they become symptomatic and surgical resection may become indicated. Spontaneous resolution of osteochondroma is rare. There have been fewer case reports about this condition. We are reporting 16 years old, male, who sustained direct trauma to his shoulder and presented with fracture at the base of a solitary osteochondroma. Complete resolution of the lesion occurred without any surgical intervention 18 months following the fracture.

Abstract
Osteochondromas are neoplasm that belong to the family of cartilaginous histogenesis tumors and represent 90% of all forms of exostoses. As most osteochondromas are asymptomatic, underdiagnosis is frequent. Symptomatic forms usually manifest before the age of 20 years, and the most common symptoms are pain and the detection of a bony mass. Herein, we report four cases of spontaneous regression of solitary osteochondromas in the light of literature. We consider that orthopedic surgeons should take into account the possibility of spontaneous regression of these tumors, before recommending surgery. Symptoms are usually mild and we recommend following these patients with X-ray and physical examination annually.

Abstract
OBJECTIVE Osteochondromas are the most common benign bone tumors, and thus far, their spontaneous shrinkage is considered a rare phenomenon. This study was designed to investigate the exact ratio of remission to progressive or stable cases and analyze the mechanism of tumor regression on the basis of existing theories. MATERIALS AND METHODS We retrospectively collected images of solitary osteochondromas in patients from 1992 to 2013, excluding cases involving short-term follow-up periods and follow-up periods that ended before growth plate closure. A total of 121 patients were diagnosed and screened for study inclusion. Tumor shrinkage was measured by assessing three points on tumor contours to determine if they had regressed or vanished. Patterns of shrinkage were further divided on the basis of mechanisms described as incorporation, absorption, and fracture. RESULTS Seventeen patients (mean age at initial diagnosis 13.1 years) met the study inclusion criteria. Tumor morphological classifications were pedunculated (10 cases) and sessile (7 cases). Osteochondroma shrinkage was the most common outcome (8 cases), followed by stable osteochondromas (6 cases), and osteochondromas that had progressed (3 cases). Tumors with sessile morphology were more prone to shrinkage (6 of 7 cases) compared with those of pedunculated morphology (2 of 10 cases; p = 0.015). Among pedunculated cases, tumor shrinkage was via absorption. The timing of tumor growth cessation was related to the pattern of tumor shrinkage. Absorption mostly followed tumor growth cessation, whereas incorporation mostly preceded tumor growth cessation. CONCLUSION The shrinkage of osteochondromas appears less rare than was originally thought.

Abstract
Osteochondromas are benign lesions manifested as bony protrusions capped by cartilage. The exact cause of these growths is not known, and there is no treatment other than surgical excision if the lesion becomes symptomatic. Spontaneous resolution is an uncommon phenomenon that is not completely understood. A 12-year-old girl presented with a mass behind the left knee diagnosed as an osteochondroma. She was followed with serial radiographs because the lesion was minimally symptomatic. At 2.5 years after presentation, the patient reported feeling a "pop" with knee hyperflexion, and radiographic follow-up confirmed a decrease in the size of the growth. The protrusion continued to decrease in size until it was no longer detectable with radiographs, physical examination, and advanced imaging. Spontaneously resolving osteochondromas have been previously documented, but the literature is limited. There were just over 20 cases reported as of the writing of this article, and only 1 other case includes postresolution magnetic resonance imaging. This report of localized trauma inducing spontaneous resolution provides additional evidence and insight supporting previous theories on spontaneous resolution of osteochondromas, which may assist in counseling patients and their families regarding expected natural history. [Orthopedics.2016; 39(5):e1001-e1004.].
