INTRODUCTION
Vertebral osteochondroma is a rare entity. It presents with varied complaints ranging from palpable mass to myeloradiculopathy. En bloc excision is the gold standard treatment option for symptomatic patients. Real-time intraoperative navigation has increased the accuracy and safety of tumor excision. We report a case of cervical subaxial osteochondroma with myelo-radiculopathy, treated with excision, and monosegmental fusion under O-arm-based real-time navigation.
CASE REPORT
A 32-year-old male presented with complaints of axial neck pain with the right upper limb radiculopathy for 18 months. On examination, signs of myelopathy were identified without sensory-motor deficit. Magnetic resonance imaging and computed tomography scans were suggestive of solitary C6 osteochondroma compressing spinalcord. O-arm navigated en-bloc tumor excision with C5 hemilaminectomy and monosegmental fusion was done.
CONCLUSION
The use of O-arm navigation aids in accurate intraoperative en bloc excision without any residual tumor and with better safety.

INTRODUCTION
Malignant transformation of pelvic osteochondroma is a rare entity. Large size and late presentation impose threat to life as well as limb. We report a case of limb salvage surgery in an enormously large secondary chondrosarcoma arising from pelvic bone.
CASE REPORT
A 60-year-old male presented with a colossal swelling at groin reaching up to distal thigh. He was walking with a wide-based gait due to pain and discomfort. 30 year back, the patient first reported this swelling of pea size, for which he was advised surgery but due to fear of surgery and economic reason he refused. Swelling gradually increased in size and reached up to distal thigh in the past 30 years. It was hard and non-tender up to 6 months back, when suddenly a change in consistency from hard to soft in distal area was noticed. On examination, a large soft cystic swelling was hanging from his pubic area. Tumor was fixed at base on proximal end. On magnetic resonance imaging, size of tumor was 281 mm in length, 263 mm in width, and 250 mm in anteroposterior diameter. Tumor was arising from superior and ischiopubic rami. However, no intra-articular extension was seen. A radiographic skeletal survey and bone scan did not reveal any other lesion. On biopsy, chondrogenic tumor composed of lobules of chondroid material with no cellular atypia or evidence of malignancy was reported. Considering the age of patient, rapid progression in recent months, size and duration of tumor, and type 3 pelvic resection was planned. Using utilitarian pelvic incision with perineal extension, separating long adductor muscles and deep femoral artery tumor, tumor excised with osteotomy at pubic symphysis, and on superior and inferior pubic rami. With minor wound complications, wound healed in 3 weeks. Post-operative biopsy reported as Grade 1 chondrosarcoma. At 3-year follow-up, the patient has no complains and no sign of recurrence noticed.
CONCLUSION
Limb salvage surgery is a suitable option even in enormously large musculoskeletal malignancy. Proper counseling and tracking of patients are must to avoid future complications.

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.

Chest wall osteochondroma resection with biologic acellular bovine dermal mesh reconstruction in pediatric hereditary multiple exostoses: A case report and review of literature.
BACKGROUND
Hereditary multiple exostoses is a rare genetic disorder characterized by the growth of multiple osteochondromas affecting primarily long bones. Chest wall lesions may represent a challenge, particularly in pediatric patients. Pain is a common manifestation. However, life-threatening complications can result from direct involvement of adjacent structures. Surgical resection with appropriate reconstruction is often required.
CASE SUMMARY
A 5-year-old male who was diagnosed with hereditary multiple exostoses presented with significant pain from a large growing chest wall exostosis lesion. After appropriate preoperative investigations, he underwent surgical resection with reconstruction of his chest wall using a biologic bovine dermal matrix mesh.
CONCLUSION
Resection of chest wall lesions in children represents a challenge. Preoperative planning to determine the appropriate reconstruction strategy is essential.

Few articles have reported on the treatment of Masada type 2 forearm deformities in hereditary multiple exostosis, possibly because of the high redislocation rate and other complications. This study precisely declares the use of modified ulnar lengthening by an Ilizarov external fixation with tumour excision for the treatment of Masada type 2 forearm deformities. 20 children with Masada type 2 forearm deformities were admitted for surgical treatment at our hospital from February 2014 to February 2021. There were 13 girls and 7 boys, ranging in age from 3.5 to 15 years (mean: 9 years) at the time of operation. We removed the prominent osteochondromas of the distal ulna and the proximal radius, positioned a classic Ilizarov external fixator on the forearm and then performed ulnar transverse one-third proximal diaphyseal subperiosteal osteotomy. We adopted modified ulnar lengthening postoperatively. The effects of surgical correction of deformity and functional improvement of the limb were assessed via regular follow-up and X-ray. The patients were followed up for 36 months, and the ulna was lengthened 26.99 mm on average; all radial heads remained relocated. The radiographic evaluations, including relative ulnar shortening, radial articular angle, and carpal slip, were improved. The functions of the elbow and forearm were all improved after surgery. Modified ulnar lengthening by an Ilizarov external fixation with tumour excision for the treatment of Masada type 2 forearm deformities in hereditary multiple exostoses has been proven to be an effective and reliable technique in the early stage.

Review
Benign tumours comprise the majority of primary vertebral tumours, and these are often found incidentally on imaging. Nonetheless, accurate diagnosis of these benign lesions is crucial, in order to avoid misdiagnosis as more ominous malignant lesions or infection. Furthermore, some of these tumours, despite their benign nature, can have localised effects on the spine including neural compromise, or can be locally aggressive, thus necessitating active management. Haemangiomas and osteomas (enostosis) are the commonest benign tumours encountered. Others include osteoid osteoma, osteoblastoma, fibrous dysplasia, osteochondroma, chondroblastoma, haemangioma, simple bone cysts, aneurysmal bone cysts, giant cell tumours, eosinophilic granuloma and notochordal rests. The majority of lesions are asymptomatic; however, locally aggressive lesions (such as aneurysmal bone cysts or giant cell tumours) can present with nonspecific symptoms, such as back pain, neurological deficits and spinal instability, which may be indistinguishable from more commonly encountered mechanical back pain or malignant lesions including metastases. Hence, imaging, including radiography, computed tomography (CT) and magnetic resonance imaging (MRI), plays a critical role in diagnosis. Generally, most incidental or asymptomatic regions are conservatively managed or may not require any follow-up, while symptomatic or locally aggressive lesions warrant active interventions, which include surgical resection or percutaneous treatment techniques. Due to advances in interventional radiology techniques in recent years, percutaneous minimally invasive techniques such as radiofrequency ablation, sclerotherapy and cryoablation have played an increasing role in the management of these tumours with favourable outcomes. The different types of primary benign vertebral tumours will be discussed in this article with an emphasis on pertinent imaging features.

Osteochondroma is a benign cartilaginous tumor that usually arises from the growth plate of the long bones. Its presentation in flat bones is uncommon. Spinal osteochondroma is a rare case, with only a 4% incidence compared to all spinal neoplasms. We report an unusual case of osteochondroma at the spinous process of the C4 spine of a 15-year-old patient with the chief complaint of neck discomfort on movement. The patient has previously been diagnosed and treated for multiple hereditary exostoses of other bones. The patient underwent surgery for the current lesion with complete excision to the base of the lesion. Histopathology revealed a benign osteochondroma with a thin layer of cartilaginous cap. The patient was healed uneventfully and had no recurrence of the lesion on the same site at the 1-year follow-up. Surgical resection remains the mainstay treatment of osteochondroma and has proved to the low recurrence. In the case of cervical osteochondroma, surgery is advisable, particularly in symptomatic patients, to prevent complications.

Solitary extraskeletal osteochondromas are rare benign lesions usually located close to a joint and are characterized by the absence of continuity with the adjacent bone. They are usually found in the hand and feet and are extremely rarely reported in the growing skeleton. In this paper, we describe a four-year-old boy who presented with a solitary calcified tumor in the posterior part of his ankle. We performed a detailed evaluation using plain X-rays, a CT scan, and an MRI, which revealed a well-demarcated calcified tumor that had the characteristics of an osteochondroma but without any continuity with the bones of the ankle joint. The lesion was treated surgically with the excision of a giant osteochondral lesion. Pathological examination revealed mature cartilage at the periphery with cancellous bone in the central part. Thus, we present the clinical and laboratory investigation of a solitary extraskeletal osteochondroma in the ankle of a four-year-old boy, which is an extremely rare case.

INTRODUCTION AND IMPORTANCE
Childhood colorectal cancers are extremely rare and so is Osteochondromatosis. Both diseases do not have epidemiological records in African countries. The aim of this report is to present a rare coexistence of CRC and multiple enchondromas in a child.
PRESENTATION OF CASE
A case of a 12-year-old boy who presented with a large bowel obstruction secondary to an advanced tumor of the descending colon. He was also diagnosed with multiple osteochondromas affecting legs, arms, ribs, scapula, clavicle and pelvis. No positive family history was recorded. An urgent left hemicolectomy and diverting transverse colostomy was done. The colon can as stage IIIB and the patient received adjuvant chemotherapy. After 8 months of follow up, the colostomy was successfully reversed without any endoscopic signs of tumor growth or distant metastasis.
CLINICAL DISCUSSION
Colorectal cancer in childhood is rare. It may present with aggressive histological subtypes in children as compared to adults. There is little to no reports on the coexistence of colorectal cancer and multiple Osteochondromatosis. Microsatellite instability in DNA tumor is common in Colon Cancer and variety of mutations of EXT-1 and EXT-2 genes goes with Enchondromatosis.
CONCLUSION
The coexistence of two rare conditions is the remarkable issue in this case report. There are no prior reports in literature. Further genomic sequencing maybe required to better understand this coexistence.
