Solitary Metacarpal Osteochondroma; an Unusual Location

Journal of Evolution of Medical and Dental Sciences, 2016

Osteochondromas, also known as exostoses are benign neoplasms, which arise from small cartilage nodules within the periosteum. They can be either pedunculated or sessile and are more common in the extremities, mostly around the knees. They rarely develop in bones like scapula, feet, hands and pelvis. Management of the lesion is by en-bloc extra-periosteal excision. This case is published for the rarity of location of the osteochondroma. CASE REPORT We present a case of 17-year male who came with a swelling in right groin since 1 year, which was diagnosed to be osteochondroma on clinical examination and radiological imaging. Excision biopsy was done as the patient wanted it to be removed for cosmetic purpose and confirmed it to be non-malignant osteochondroma. There has been no recurrence at 1 year of followup. CONCLUSION Thus osteochondroma of the pelvis should be kept in mind as a differential diagnosis when evaluating mass in pelvis. Also these have to be removed when they pose cosmetic problems.

Scapular osteochondroma can have unusual manifestations like pseudo-winging and snapping syndrome in ventrally located lesions. Dorsally located lesions cause a cosmetic blemish and difficulty in lying supine. We present a series of 3 cases of scapular osteochondroma with varying presentations. One was a ventral surface (subscapular) osteochondroma which presented with pseudo winging and snapping syndrome and 2 were dorsal surface osteochondromas which presented with prominence at the back and difficulty in lying supine. All were treated surgically with good functional and cosmetic results. Surgical resection of tumor is the treatment of choice. An appropriate surgical approach should be chosen depending on the location of tumor. We propose the use of trapezius sparing approach and splitting the scapular apophysis for subscapular osteochondroma in children as it produces less soft tissue damage, is easy to repair and allows early rehabilitation.

Osteochondromas are the rare benign and malignant tumour of the growing bone, usually affecting the young adults. Solitary osteocartilaginous exostosis is more common than the hereditary multiple exostosis (HME). The first 3 decades of life has maximum chances of getting affected with osteochondroma and hardly occurs in craniofacial bones because of the fact that these bones are not formed by endochondral ossification. Most of the symptoms occur at the periphery of the bone tissues, with causes of osteochondroma being unknown. It involves in genetic condition and is associated with mutations of EXT1 or EXT2 genes. Diagnosis is difficult at symptomless stage, incidentally it is diagnosed when X-ray is carried out. Detection of tumor by ultra sound is accurate than other diagnosis process. No treatment is required other than regular monitoring of tumor. Standard allele specific PCR based techniques on osteochondroma showing both recombine and intact alleles were reported. The observat...

Osteochondroma is the most common benign tumor of the bone that occurs predominantly in metaphyseal regions of the long bones but rarely involves flat bones like scapula. However, this is often the most common primary benign bone tumor affecting scapula. These tumors usually occur in the growing age and cease to extend in size after skeletal maturity. Any increase in swelling of an asymptomatic swelling turning symptomatic should raise the suspicion of a malignancy. Here, we presented a case of swelling over the left scapula of a fourteen-year-old boy by his parents since the past three years, which showed no progress since last 1 year but however they presented to the hospital for cosmetic reasons. We performed an open extra periosteal resection of the osteochondroma using modified Judet’s approach after diagnostic workup and ruling out malignancy and confirmation by post operative histopathological study of resected lesion. Patient was able to perform full range of motion at his l...

The occurrence of osteochondroma around the proximal femur is rarely reported as most cases are asymptomatic. We report a rare case of symptomatic solitary osteochondroma arising from the lesser trochanter in a skeletally mature patient causing significant impairment of hip function managed by surgical excision. A 32-year-old male labourer presented with pain and swelling over right hip region for nine months. Radiographic examination (X-ray, MRI, CT) revealed the pathognomonic continuity of the cortex and medulla of the lesion with the parent bone. Cartilage cap cover (measuring 15 mm) on MRI helped to clinch the diagnosis. CT guided biopsy was also suggestive of osteochondroma. The tumour was excised en bloc by posterior approach without the need for hip dislocation. The base of the lesser trochanter was osteotomised and the entire mass with the cartilage cap was removed. A two year follow up has shown no evidence of local recurrence. Surgical excision of a symptomatic osteochondr...

Osteochondromas are the most common benign tumors of the bone. They mostly arise from the appendicular skeleton and present clinically in the second or third decade of life. Ostechondromas arising from the subaxial cervical spine and presenting after the 5th decade of life are extremely rare. We report a 52-year-old male patient who presented with numbness and subjective weakness of left upper and lower limbs and neck pain, and had lobulated bony hard fixed swelling in the right lower cervical paraspinal region. Radiological images revealed a bony swelling arising from C4 and C5 lamina with a cartilaginous cap and intraspinal extension. Excision biopsy with stabilisation of the spine was performed. Histopathalogical examination of the specimen confirmed the diagnosis of osteochondroma. We conclude surgical excision of such rare tumors, including the cartilaginous cap as well as the intraspinal component can reliably produce a good clinical outcome.

Osteochondroma is generally known as osteocartilaginous exostosis and one of the most common benign tumors of long bones, accounting for about 35%~50% of benign tumors and 8%~15% of primary bone tumors. However it is very rare in the facial skeletal bone especially as a solitary type. Osteochondroma is formed as a result of endochondral ossification and increase in size via endochondral ossification from an abnormal cartilaginous epiphyseal growth plate tissue. In the craniofacial region, the most common sites of occurrence are the mandibular coronoid process and the condyle of mandible.

Osteochondromas are the most common benign tumours of bone. They are most commonly seen in the metaphyseal regions of long bones (femur, tibia, humerus). The scapula is rarely involved, and very few cases of solitary osteochondroma of scapula have been reported in literature. We present the case of a 17 year old male who presented with pain and limited range of motion of his right shoulder. CT scan revealed an osteochondroma on the dorsomedial surface of the right scapula extending into the ventral surface. Surgical excision was done and histopathological study showed osteochondroma of the scapula.

Introduction: Osteochondroma are benign bone tumours that often affect the metaphysical region of long bones; the scapula is rarely affected. Owing to its bulk effect, scapular osteochondroma may frequently present with symptoms. These tumours typically damage the skeleton's developing ends and stop becoming larger once the skeleton reaches maturity.Suspicion of a cancer should be raised by any increase in size Case Report: A female patient, age 25, complained of a hard lump on her shoulder posteriorly on further imaging it was confirmed as an osteochondroma of scapula Discussion: Osteochondromas must exhibit continuity with the underlying parent bone cortex and medullary canal. They are made up of cortical and medullary bone with an overlaying hyaline cartilage cap. They have a very minimal potential for malignancy and are often asymptomatic. Conclusion: The cases of osteochondromas in the scapula are relatively rare, it is crucial to remain vigilant and consider the possibility of malignancy if there are concerning changes in symptoms or size.

No scars, sinuses, or distended veins. X-ray of the left ankle showed exostosis arising from the body of the talus (Fig. 1). Under tourniquet control, through posteromedial approach to ankle, skin incision made longitudinally midway between medial malleolus and Achilles tendon, deep fascia incised, and Achilles tendon retracted exposing deeper flexor compartment, fibro-osseous tunnel over flexor halluces longus tendon incised and posterior tibial artery with tibial nerve retracted medially: exostosis found arising from the body of talus removed using a bone chisel and sent for histopathology (Figs 2 and 3). Histopathological examination (HPE) confirmed the diagnosis as osteochondroma. In this case, surgical excision was performed in view of prevention of further progression of pes valgus deformity and to prevent neurovascular compromise. The patient was immobilized with below knee slab until suture removal on 12th postoperative day followed by below knee cast for another 2 weeks and then allowed weight-bearing. However the parents were informed regarding the chances of recurrence and malignant transformation in future. Case 2 A 55-year-old female presented with right elbow deformity and restricted range of movements of the right elbow for past 2 years. No history of trauma, previous surgeries, immobilization, or native treatment in the past. No scars, sinuses, or distended veins.
