Successful complete thoracoscopic resection of costal osteochondroma: A case report.

Osteochondroma rarely occurs in the ribs; therefore, the treatment is not standardized. There are few studies of resection via complete thoracoscopic surgery (CTS), although video-assisted thoracoscopic surgery with mini-thoracotomy has been reported. Herein, we report a case of costal osteochondroma managed with CTS. A 23-year-old woman presented to our hospital due to left chest pain. Chest computed tomography revealed a bone-like structure protruding into the thoracic cavity from the left fourth rib. Thus, surgery was performed to obtain a definitive diagnosis and provide appropriate treatment. The tumor was resected from the base at the border of the normal bone via CTS using three 5.5-mm ports. A pathological diagnosis of costal osteochondroma was made. The patient had an uneventful clinical course and did not present with a recurrence 1 year after surgery. Therefore, CTS can be a good approach for cases with slim and stalked costal osteochondroma.

Resection of the entire first rib for giant osteochondroma by trans manubrial approach: a case report and review of the literature.

BACKGROUND: First rib tumors are extremely rare. Its compression of neurovascularity can easily lead to severe complications such as thoracic outlet syndrome, so early surgical resection is crucial. However, there is no standardized approach to surgery. CASE PRESENTATION: A previously healthy 18-year-old Chinese male undergoes a chest computed tomography (CT) scan that incidentally reveals a raised calcified mass on the right first rib, which is most likely an osteochondroma when combined with magnetic resonance imaging (MRI). We achieved excellent results with resection and thoracic reconstruction by adopting an inverse L-shaped incision in the anterior chest and a longitudinal split of the sternum. CONCLUSIONS: Our practice provides great reference for the surgical management of first rib tumors.

Pedunculated Osteochondroma Presenting as Verruca Vulgaris: A Diagnosis Requiring a High Index of Suspicion: Case Report.

Introduction: Osteochondromas are the most common benign tumors of the bone and can be sessile or pedunculated. Although osteochondromas are typically seen in the long bones, they are rarely seen in the small bones of the hand or foot. Verruca vulgaris, also known as the common wart, is one of the most common skin conditions presenting to physicians and must be distinguished either clinically or histologically from other hyperkeratotic conditions, including bone conditions such as bone tumors that can place pressure on the skin and cause callus formation that can mimic a wart or create skin deformity. A high index of suspicion for underlying bone mass or tumor should be entertained when evaluating patients for skin conditions, particularly of the hand or foot, with failure to improve with treatment. Case Report: This case report presents a 20-year-old male with a pedunculated osteochondroma of the left fourth distal phalanx with hyperkeratotic skin overlying the mass at the end of the toe. He was initially treated by a family doctor and podiatrist for verruca vulgaris for over 5 years with two treatments of liquid nitrogen cryotherapy and surgical excision of the mass when the treating podiatrist encountered bone and recommended radiographs. The family requested follow-up with our practice several days later after they were told the patient had a bone tumor. The patient requested surgical excision of the osteochondroma secondary to pain with activities and difficulties with his vocation as a pilot. Conclusion: All physicians must be mindful of an underlying bone tumor or mass in patients presenting with skin changes, particularly about the foot or hand. Knowledge that an underlying bone tumor can present as a verruca vulgaris may prevent a delay in diagnosis or unnecessary treatment when evaluating and treating a patient with a skin lesion. Fortunately, our case was a benign osteochondroma; a malignant tumor with a delay in diagnosis could lead to loss of limb or life.

A Unique Presentation of Vertebral Body Osteochondroma of Sixth Cervical Spine Causing Myelopathic Symptoms: Management with En bloc Excision and Cervical Fusion.

Introduction: Vertebral body osteochondroma presenting with myelopathic symptoms is exceptionally rare entity of spinal osteochondroma which arises from the posterior surface of vertebral body and leading to spinal canal stenosis and cord compression. Early definitive diagnosis and subsequent successful treatment is necessary in such cases to prevent life threatening complications. Case Report: In this context, we report a case of a 20-years old female presented with mechanical neck pain, unsteady gait, giddiness with neurological deficit for the past 3 months. An MRI of the cervical spine revealed a mass growing from the posterior aspect of the C6 vertebral body and extending toward the vertebral canal, causing marked spinal cord compression. Conclusion: The following case report not only describes the rare presentations of vertebral body osteochondroma but also emphasizes on surgical management by en bloc resection of tumor and anterior cervical fusion, resulting in a favorable outcome without any recurrence.

Vascular complications of tibial exostosis: A rare case of popliteal vein deep venous thrombosis.

INTRODUCTION AND IMPORTANCE: Tibial exostosis (osteochondroma) represents a prevalent benign bone tumor typically identified in young adults. Uncommonly, vascular complications can emerge, encompassing vessel perforation, thrombosis and arterial thromboembolic events. Rare instances of popliteal vein thrombosis resulting from tibial osteochondroma have been documented. CASE PRESENTATION: We report a rare case of a 25-year-old patient who presented with a red and swollen leg, and the diagnosis of deep venous thrombosis (DVT) of the left popliteal vein was established. The patient also exhibited a painless, hard swelling in the popliteal fossa. Radiography revealed an exostosis on the posterior aspect of the proximal tibia. An angioscan demonstrated close relations with the popliteal vessels, leading to venous compression. The patient underwent resection through a posterior knee approach. Histopathological analysis of the exostosis ruled out malignant transformation. CLINICAL DISCUSSION: The discussion emphasizes the need for prompt diagnostic measures when signs indicate a vascular concern in a young patient, initiating with a radiograph followed by Doppler ultrasound and/or angiography to diagnose complications and precisely delineate their relationships with the tumor. Surgical intervention is underscored as urgent, particularly in cases involving arterial thrombosis, where immediate measures such as thrombectomy or bypass with a venous graft may be necessary. CONCLUSION: Vascular complications associated with bone exostoses are rare but require prompt surgical treatment. However, it should prompt the performance of an angioscan in the presence of any abnormalities during clinical examination or an appearance raising concerns about potential vascular conflict.

Condylar Osteochondroma: A Rare Case Report.

Osteochondroma (OC) is an uncommon reason for the mandibular condyle to grow excessively. Usually unilateral, it can impact the entire mandible, the condyle and ramus, or just the condyle. It is a bony projection covered in cartilage that protrudes from the damaged bone's exterior. Condylar OC are more prevalent as a result of endochondral ossification-related development. The most notable characteristic is the gradual asymmetry of the face over time. Clinical symptoms of the patient include pain, asymmetry, malocclusion, partial or total hearing loss, trismus, and hypomobility of the TMJ. We report a case of 40-year-old male patient complaining of reduced mouth opening since last 10 years. Clinical examination revealed gross facial asymmetry, hard swelling over right TMJ, jaw deviation towards left side, restricted mouth opening of 3 mm and deranged occlusion. An irregular radiopaque mass was seen over the right condylar region in OPG. A large, hyperdense mass that obliterated the sigmoid notch and extended medially to the right condyle was visible on CT scans. Using a pre-auricular Alkayat-Bramley technique, the mass was surgically removed. Occlusal corrections and jaw physiotherapy were then administered. On follow up, deviation was corrected and adequate mouth opening was achieved.

Excision of a Distal Tibial Interosseous Osteochondroma Through Posterolateral Approach: A Case Report.

Osteochondromas arising from the interosseous border of the distal tibia are rare, but cases have been reported previously in the literature. In long-standing cases, they can cause a "mass effect" resulting in the deformation of the bones around the ankle joint, mechanical restriction of joint movement, and even degenerative joint disease. Hence, they need to be resected if patients present with such impending complications. Several surgical techniques have been described previously for tumor resection including the anterior approach and the trans-fibular approach, the latter of which required a fibular osteotomy with or without fibular reconstruction. The surgical technique described here utilizes the posterolateral approach to the ankle joint for tumor excision, thus avoiding the need for any osteotomy or fibular reconstruction and reducing the risk of injury to major neurovascular structures. It also reduces the need for long-term immobilization and promotes a faster return to activity.

Conservative Rehabilitation Program for Osteochondroma of the Scapula: A Case Report.

One of the most frequent cartilage-capped outgrowths that develop beneath the periosteum due to cartilage ossification is osteochondroma. The second decade of life is noted as the most prevalent age of presentation. This case report looks at an uncommon osteochondroma presentation in a 20-year-old female with swelling along the right inferomedial border of the scapula. The patient presented with complaints of difficulty in daily activities and exhibited altered posture, decreased range of motion (ROM), muscle weakness, and altered shoulder function. The clinical assessment highlighted restricted shoulder and cervical ROM and muscle weakness in the trapezius, rhomboids, serratus anterior, and other surrounding muscles. Magnetic resonance imaging revealed an inferomedial bony outgrowth indicative of osteochondroma. A comprehensive physiotherapy intervention protocol for eight weeks was designed to alleviate pain, improve mobility, restore ROM, strengthen weakened muscles, correct posture, and enhance functions that were restricted. The protocol encompassed various techniques, such as muscle energy techniques (MET), proprioceptive neuromuscular facilitation (PNF), cold therapy, stretching, scapular mobilization, resistance exercises with TheraBand, postural correction exercises, ergonomic adjustments, scapular stabilization exercises, and 'J'-taping to aid in muscle activation and address rounded shoulder posture. Outcome measures for cervical and shoulder ROM and strength were measured to note the progression after rehabilitation. The case report emphasizes the importance of a tailored physiotherapy rehabilitation protocol in managing osteochondroma-related symptoms, showing the potential benefits of multifaceted interventions in alleviating pain, improving function, and boosting the quality of life for individuals with similar presentations.

A Huge Osteochondroma With Chest Wall Deformity Arising From the Ventral Scapula.

Osteochondromas (OC), or exostoses, are developmental defects rather than true neoplasms. Misdirected physeal bone growths give rise to OC. It causes cartilage-capped bony extensions to emerge from the lateral outlines of endochondral bones. We discuss a case of OC in a 35-year-old female who presented with severe chest wall deformity and breathlessness due to compromised left lung function. CT scan showed a vast osteochondroma arising from the ventral surface of the scapula, which was palpable in the supra mammary region on the left side. The tumor mass was completely excised from the base of the stalk. Her breathlessness and compromised left lung function returned to normal in the post-op period. However, the chest deformity was corrected over two months. The article provides insights into the presentation in a patient with such a massive tumor due to its location. Surgical excision should be the treatment of choice for huge osteochondromas.

Pediatric diaphragmatic hernia induced by a rib osteochondroma.

Diaphragmatic hernia in children is uncommon, especially when not congenital. We present a case of an 11-year old boy with a diaphragmatic hernia caused by a rib osteochondroma. The osteochondroma was surgically removed and the laceration in the diaphragm was repaired. This case shows the importance of being familiar with acquired diaphragmatic hernia in children, to recognize and prevent possible complications in an early stage.

Intracranial osteochondroma arising from the posterior clinoid process: a rare case report with diagnostic challenges and comprehensive literature review.

Introduction and importance: Intracranial osteochondroma is rare, presenting diagnostic challenges due to overlapping imaging findings with other pathologies. This case report highlights the significance of considering osteochondroma in calcified tumour differentials near bone. Case presentation: A 34-year-old man with vision deterioration and headaches had an MRI revealing a suprasellar lesion. Intraoperatively, a bony hard tumour was partially resected. Subsequent computed tomography (CT) confirmed a calcified mass contiguous with the posterior clinoid. Clinical discussion: Reviewing 28 cases, skull base osteochondromas were common, with differential diagnoses including craniopharyngioma and meningioma. Surgical decision-making involved balancing complete resection for convexity and falx cases versus partial resection for skull base tumours due to proximity to critical structures. Conclusion: Intracranial osteochondroma poses diagnostic challenges, especially near bone. Tailored surgical approaches are vital, with complete resection yielding good outcomes for convexity and falx cases. Close follow-up is crucial for monitoring recurrences and complications.

Osteochondroma of Antero Medial Maxillary Wall - A Rare Case Report.

A 17 year female came with complaints of swelling over left lateral wall of nose and left nasal block was found to have osteochondroma of maxilla on CT PNS, resected by sub labial approach with postoperative histopathological confirmation. Thus describing a rare case of osteochondroma of maxilla treated without any cosmetic and functional impairment.

Vascular complications of tibial exostosis: A case of popliteal vein thrombosis.

Tibial exostosis, also known as osteochondroma, is a common benign bone tumor found predominantly in adolescents and young adults. Vascular complications associated with this tumor, such as arterial occlusion and pseudoaneurysm formation, are rare but can lead to significant morbidity if not promptly diagnosed and managed. We present a case of a 25-year-old patient who presented with thrombosis of the left popliteal vein and a painless swelling in the popliteal fossa. Radiographic and CT angiography revealed an exostosis on the proximal tibia causing arterial occlusion and venous compression. Surgical resection of the exostosis via a posterior knee approach resulted in successful resolution of symptoms and a favorable outcome at a 12-month follow-up. Histopathological examination confirmed the benign nature of the tumor with no evidence of malignant transformation. This case highlights the importance of prompt recognition and surgical intervention in managing vascular complications associated with tibial exostosis. A multidisciplinary approach involving orthopedic and vascular specialists is crucial for achieving optimal outcomes in such cases.

Multiple Hereditary Exostoses instigating a popliteal pseudoaneurysm in a young Middle Eastern male: A case report and literature review.

INTRODUCTION AND IMPORTANCE: Multiple Hereditary Exostoses is a rare autosomal dominant bone disorder that predominantly affects males at an incidence of (1:50,000 to 1:100,000) in Western populations. The etiology is owed to mutations in the EXT gene group, specifically EXT1 and EXT2 which cause the formation of Osteochondromas. Diagnosis is typically established in childhood. Nevertheless, vascular complications are extremely rare while being potentially fatal. Therefore, timely diagnosis and treatment are vital for such patients. CASE PRESENTATION: We present the case of a 37-year-old Middle Eastern male with Multiple Hereditary Exostoses who experienced sudden-onset left lower limb pain persisting for a month prior to admission. It was associated with coldness and paresthesia of the ipsilateral lower limb. The presurgical radiological workup uncovered a popliteal pseudoaneurysm subsequent to Multiple Hereditary Exostoses. CLINICAL DISCUSSION: Through open surgery, the vascular perfusion was successfully restored, and a subsequent supra- to infra-geniculate popliteal artery anastomosis via saphenous vein grafting was done. Furthermore, the Osteochondroma was utterly resected to limit recurrence of another vascular injury. The following histopathological analysis confirmed the diagnosis of an Osteochondroma as a result of MHE. CONCLUSION: Multiple Hereditary Exostoses is a rare occurrence leading to pseudoaneurysms. This event underscores the need for further documentation to aid in establishing a prompt diagnosis and carrying out suitable interventions. Considering this pathology in a multidisciplinary approach ensures proper treatment. Following a comprehensive literature review, our case stands as the first case in the published literature from our country which emphasizes its value and rarity.

Extensive Osteochondroma of the Talus Presenting As Syndesmotic Joint Extension and Posterior Inferior Tibiofibular Ligament Rupture: A Reportof a Rare Case and a Review of the Literature.

This case report describes a rare occurrence of talar osteochondroma extending into syndesmosis, causing disruption of the interosseous membrane and the posterior inferior tibiofibular ligament (PITFL). This type of presentation for a talar osteochondroma is the first of its kind reported in the literature based on current knowledge. A detailed preoperative radiological assessment was crucial in planning the surgical approach and preparing for syndesmotic stabilization during the excision. The patient underwent successful and complete excision of the osteochondroma, and the syndesmosis was stabilized using a cortical screw along with anatomical repair of the PITFL. Apart from delayed wound healing, the patient exhibited good functional outcomes in terms of gait and ankle range of motion at the six-month follow-up. This case serves as a valuable reference for similar presentations in the future, emphasizing the importance of thorough preoperative assessment and appropriate treatment planning.

BPOP in early childhood following resection of osteochondroma: report of a case.

The diagnosis of an osteochondroma in the short bones of the extremities is atypical and the presentation in infancy is unusual. A 3-month-old female presented for evaluation of radial deviation of the right index finger present since birth. Radiographs showed a broad-based osseous outgrowth with the usual features of an osteochondroma arising from the base of middle phalanx. Initial corrective surgery at 22 months was followed by recurrence of the lesion. Another resection at 4 years confirmed a final diagnosis of BPOP (bizarre parosteal osteochondromatous proliferation). The subsequent pathologic diagnosis of BPOP appears to support the hypotheses concerning the etiology of BPOP as possibly arising from repeated trauma to the metaphysis.

Bizarre parosteal osteochondromatous proliferations of the temporal region: a case report.

Bizarre parosteal osteochondromatous proliferations (BPOPs) are distinct clinical-pathological entities that demonstrate combinations of atypical-appearing osseous and chondromatous tissues. These lesions are usually reactive in nature. Histopathologically, 'bizarre' cartilage is a characteristic feature of this lesion. BPOPs usually represent slow-growing painless bony hard protuberances that arise from the surface of affected bone cortices, typically the metacarpals, metatarsals, and phalanges. The occurrence of these lesions in the skull and jaws is sporadic. This case report highlights the clinical presentation, histopathological characteristics, and management of BPOP arising from the supraorbital rim in a 61-year-old female patient.

Osteochondroma of the superomedial scapula managed with a novel muscle sparing approach: case report and review of literature.

Osteochondromas are a common type of benign primary bone tumor rarely occurring in the scapula. When it is symptomatic, surgical removal is recommended. There are multiple approaches for surgical excision that can be used depending on the location and size of the tumor. We present a case of a 14-year-old female who was seen in the orthopedic clinic with right shoulder pain, mechanical symptoms and medial scapular winging due to a superomedial osteochondroma of the scapula. A novel superior approach to the superomedial ventral surface of the scapula was utilized to excise the tumor with good clinical results.

Tumors of the Posterior Elements of the Spine in Children-an Overview.

In this narrative review, we aim to describe the clinical features, diagnosis, and management of common primary osseous tumors affecting the posterior elements of the spine in children. We searched PubMed, Mendeley, and Google Scholar using the terms primary osseous tumors of the spine in children, tumors of the posterior elements of the spine, and names of individual tumors. The clinical features, investigations, and treatment modalities were analyzed, and a narrative review of the topic was prepared. We have included 54 studies published in the last 20 years. The majority are isolated reports or case series. Tumors of the posterior elements of the spine are rare. They are common in children and the majority of them are benign. Pain and deformity are common presentations. It is better to perform thorough investigations of children complaining of back pain to rule out primary tumors of the posterior elements of the spine.

Update of cartilaginous tumours according to the WHO classification 2020.

Cartilaginous tumours are a large and heterogeneous group of neoplasms characterised by the presence of a chondroid matrix, with lobular growth and arcuate, ring-like or popcorn-like calcification patterns. MRI shows hyperintensity in T2-weighted sequences and a lobulated or septal relief in postcontrast images. In the WHO 2020 classification, chondral tumours are classified as benign, intermediate or malignant. Despite technological advances, they continue to pose a challenge for both the radiologist and the pathologist, being the main difficulty the differentiation between benign and malignant tumours, which is why they require a multidisciplinary approach. This paper describes the main changes introduced in the 2020 update, describes the imaging characteristics of the main cartilaginous tumours and provides the radiological keys to differentiate between benign and malignant tumours.
