Giant solitary osteochondroma of the inferior medial calcaneal tubercle: a case report and review of the literature

A Solitary, Large Calcaneal Osteochondroma Growing Extensively After Skeletal Maturity: A Case Report and Review of the Literature

Although osteochondromas are the most common benign tumors in the skeleton, calcaneal osteochondromas are very rare. New onset of pain or rapid growth of the tumor, especially after the closure of the epiphyseal growth plate, might reflect malignant transformation. However, enlargement of solitary osteochondromas reported as benign in a skeletally mature patient is present in the literature. We report the clinical and radiologic findings of a calcaneal osteochondroma with an extremely rare placement and painful rapid growth causing limited ambulation in a 27-year-old male. After surgical removal of the tumor, histologic examination demonstrated no evidence of malignancy, and there was no recurrence during the three-year follow-up.

Solitary Osteochondromas of the Metatarsal and Cuneiform, in an Adolescent

Introduction

Solitary osteochondromas are extremely rare in the bones of the foot. In the growing skeleton, few cases affecting the metatarsals and the talus have been reported. At present, there have been no reports of osteochondromas affecting the cuneiforms.

Case Report

We report the case of a 13-year-old male patient. He presented with marked prominences in the plantar surface of his left foot and pain while participating in sporting activities. Radiological examination with X-rays, computed tomography (CT) scan, and magnetic resonance imaging revealed two solitary osteochondromas growing from the medial cuneiform and the head of the 1st metatarsal. The patient was treated surgically by excision of the osteochondromas. Histological examination confirmed the diagnosis of osteochondromas. He had an uneventful recovery and returned to his sporting activities.

Conclusion

Solitary osteochondroma can present in the cuneiform and metatarsal of a growing adolescent. CT scan is useful for the accurate diagnosis and surgical removal of the tumor.

Calcaneal osteochondroma masquerading as plantar fasciitis: An approach to plantar heel pain - A case report and literature review

BACKGROUND

Heel pain is a common orthopaedic complaint, and if left untreated can be a source of chronic morbidity. Accurate diagnosis can be challenging, owing to the complex anatomy and multiple pain generators present in the foot. We aim to share our clinical experience managing an unusual case of chronic heel pain secondary to osteochondroma.

CASE SUMMARY

A 41-year-old obese male who works as a porter presented with a long-standing history of left plantar heel pain. He was assessed to have point tenderness over the plantar insertion of the calcaneus as well as a positive Silfverskiöld test. He was treated for plantar fasciitis and tight gastrocnemius but failed conservative therapies as well as surgical intervention. Magnetic resonance imaging revealed the presence of a pedunculated bony protrusion over the plantar aspect of the calcaneus. The decision was made for excision of the osteochondroma, and the patient has been pain-free since.

CONCLUSION

Osteochondromas are rarely symptomatic in skeletally mature patients. While most are benign with a very low risk of malignant transformation, surgical excision can yield excellent results and significant pain relief in symptomatic patients.

Primary tumours of the calcaneus

The calcaneus is a rare location for the occurrence and development of primary tumour types. Clinicians are unfamiliar with calcaneal tumour types, which may result in a delay in diagnosis or a missed diagnosis, resulting in unnecessary morbidity and amputation. Heel pain and localized swelling of the ankle are the most common symptoms. X-ray is the first choice for a tentative diagnosis of a calcaneal tumour. The final diagnosis depends on a histological examination. The treatment of calcaneal tumour types varies depending on the Enneking system. The majority of patients with benign tumours heal, except for a few with a palindromia. For malignant tumours, the prognosis is comparatively poor, resulting in disability and a high rate of metastasis. This review describes the spectrum of calcaneal tumour types and specifically illustrates the epidemiology, symptomatology, imagology, histopathology and treatment options that may facilitate diagnosis and improve prognosis.

Osteochondroma and Spinal Cord Compression in a Patient With Hereditary Multiple Exostoses: A Case Report

OBJECTIVE

The purpose of this report was to describe the presentation of a patient with hereditary multiple exostoses and thoracic spinal cord compression from an osteochondroma.

CLINICAL FEATURES

A 31-year-old female presented to a chiropractic clinic with a history of hereditary multiple exostoses and back pain that had existed since the age of 16 years. She had a past medical history that was remarkable for 3 prior surgeries for mass removal. Examination revealed a left upper midscapular mass with decreased sensation.

INTERVENTION/OUTCOME

Magnetic resonance imaging, computed tomography, and biopsy led to a diagnosis of osteochondroma. These diagnostic modalities confirmed that there was no malignant degeneration. Initial magnetic resonance imaging revealed a large expansive lesion involving the left posterior elements at the region of T3-T4. Subsequent thoracic hemilaminectomy and resection of the spinal tumor with posterior instrumentation and stabilization from T2-T5 resulted in 90% overall subjective improvement.

CONCLUSIONS

A detailed case history, thorough examination, guided advanced imaging, and biopsy provide important information for the diagnosis and appropriate treatment of expansive lesions in patients with hereditary multiple exostoses.

Retrocalcaneal Bursitis due to Rare Calcaneal Osteochondroma in Adult Male : Excision and Outcome

Introduction:

Osteochondroma is the most common benign tumour of the bone and is considered as developmental lesion of the bone. Common site of osteochondroma presentation is around the knee but calcaneal osteochondroma as such is a rare entity. Osteochondromas grow during childhood through adolescence, but usually the growth of osteochondroma ends when the epiphyseal plates close. In an adult, growth of an osteochondroma suggests the diagnosis of a malignant transformation. However, it can also present as pressure symptom in later phase of life. Here, we presented a case of retrocalcaneal bursitis in late phase of life of a male farmer due to late growth of osteochondroma.

Case Presentation:

We report a case of calcaneal osteochondroma which is an extremely rare site of occurrence with painful swelling of ankle causing limitation of walking in a 58-year-old male. Surgical excision of tumour followed by a histological confirmation reported negative for any malignant changes.

Conclusion:

There may be chances of osteochondroma being a reason for retrocalcaneal bursitis. It is possible of late detection of benign osteochondromas which show symptomatic growth and pressure effect in skeletally mature patients without malignant transformation.

Talar Osteochondroma Fracture Presenting as Posterior Ankle Impingement

Osteochondromas are the most common benign bone tumors. They are usually asymptomatic and found incidentally. When symptomatic, the symptoms are usually due to its location and size. Fracture of an osteochondroma presenting as posterior ankle impingement is a rare condition. We describe a 22-year-old man with solitary exostosis who presented with a posterior ankle mass and posterior ankle impingement with 2 years of follow-up. Surgical intervention was the treatment of choice in this patient, and histologic examination revealed a benign osteochondroma. Osteochondromas found in the posterior aspect of the talus can be complicated by fracture due to persistent motion of the ankle. Talar osteochondroma should be included in the differential diagnosis of posterior ankle impingement causes. Posterior talar osteochondromas, especially when a stalk is present, should be treated surgically before it is more complicated by a fracture and posterior ankle impingement.

Limb Salvage in Secondary Chondrosarcoma of the Metatarsus

Malignant transformation of metatarsal osteochondroma into chondrosarcoma is a rare entity. The most optimal line of treatment, salvage procedure or amputation, continues to be debated. Both of these treatments have varied in popularity. We report the case of a 24-year-old male with chondrosarcoma secondary to differentiation of an osteochondroma in the second and third metatarsals. Wide resection of the tumor mass and reconstruction of the second and third metatarsals was performed using a simple and biologic approach. This was accomplished with an autologous nonvascularized fibular graft to reconstruct the longitudinal arch of the foot. The foot was successfully salvaged, with good anatomic, functional, and aesthetic results. At 1 year postoperatively, the patient was able to walk without any orthotic devices and had returned to his routine work. No evidence of local recurrence or metastasis was observed.

Diagnosis of hyperostosis of the medial calcaneal tubercle similar to a heel spur

Calcaneal osteochondromas are rare conditions. To our knowledge, we present the first report of a calcaneal osteochondroma in an adolescent patient that was surprisingly similar to a heel spur, and, in addition, symptoms due to compression of the medial plantar nerve were present.

Osteochondroma of the OsCalcaneum- A Case Report

Osteochondromas are common benign bone tumours. They usually occur in the patients who are below thirty years of age. They probably are developmental malformations rather than true neoplasms. They are believed to originate within the periosteum as small cartilaginous nodules. The foot is rarely a common site of presentation for these tumours. The calcaneum is one of the most unusual regions for the occurrence of osteochondromas 1. The osteochondromas which arise from the calcaneum, especially those which project onto the plantar surface, pose considerable problem to the ambulation. Malignant transformations are seen in less than 1% to 2% of the patients with solitary osteochondromas 2. We herewith present a case of osteochondroma which arose from the calcaneum, which was surgically excised to improve the patient's daily functioning. The patient was followed up for a period of one year. She is now able to walk comfortably.

Large soft tissue osteochondroma of the heel: a case report and literature review

Soft tissue osteochondromas are the rare tumors of the foot. We present an unusual case of a 30-year-old woman who had a large osteochondroma originating from the soft tissue in the heel region. She made an uneventful recovery following excision. No recurrence was noted at 36 months follow-up. To the best of authors' knowledge, such presentation has not been reported before in the English language-based medical literature.

Osteochondroma of the calcaneus presenting as Haglund's deformity

Haglund's deformity is a symptomatic osseous prominence of the posterosuperior corner of the calcaneus creating posterior heel pain and swelling around the insertion of the Achilles tendon. We have experienced an exceptionally huge Haglund's deformity in a 22-year-old female who initially presented to us with a large painful bony heel mass that had developed over the last decade. We performed the surgical resection of the prominence and the pathology confirmed the diagnosis of calcaneal osteochondroma. To our best knowledge, such a gigantic Haglund's deformity caused by calcaneal osteochondroma has never been reported in any medical literature.

Soft-tissue osteochondroma of the heel pad: a case report and review of literature

Extraskeletal osteochondroma of the foot are rare benign cartilaginous tumours. We present a case of soft-tissue osteochondroma in the heel pad superficial to the postero-inferior aspect of the calcaneus. We propose the pathogenesis of this lesion might be related to metaplasia in the plantar aponeurosis as described in literature, or it may be a fracture of the calcaneal osteochondroma, growing and presenting as soft-tissue lesion in the heel pad.

Arthroscopic removal of an intraarticular osteoid osteoma of the distal tibia

Intraarticular osteoid osteomas can simulate several other traumatic or degenerative pathologies of the joint with delay in diagnosis. We report the clinical features, radiographic and histopathological findings, the technical aspects of arthroscopic excision, and results of surgery in a 28-year-old woman who had an intraarticular osteoid osteoma of her left ankle, in whom the initial diagnosis was erroneous and delayed 1 year. Arthroscopy allowed minimally invasive complete excision of the osteoid osteoma, with a short postoperative rehabilitation and excellent functional results.

Giant solitary osteochondroma arising from the fifth metatarsal bone: a case report

Accounting for 20% to 50% of all benign forms, solitary osteochondroma is the most common bone tumor. The long bones of the lower extremity are most frequently affected, whereas the small bones of the hands, feet, pelvis, scapula, and spine are less common locations. Osteochondromas are benign osseous neoplasms with a distinct hyaline cartilage cap originating from the physis, and they cease to grow with skeletal maturity. Treatment of osteochondroma is usually conservative, unless symptoms, usually pain, are progressive or the lesion demonstrates rapid or new growth, or if enlargement after skeletal maturation is noted or malignant transformation is suspected. In this report, we describe the case of an adult with a giant, symptomatic osteochondroma localized to the fifth metatarsal. The lesion was treated with excision, and after more than 2 years of follow-up, no evidence of recurrence was noted. This case demonstrated that, despite the benign nature of the lesion, a large osteochondroma could localize to a metatarsal.

Resection and reconstruction of an osteochondroma of the hallux: a review of benign bone tumors and a description of an unusual case

Osteochondroma, which is also known as exostosis, is the most common benign bone tumor. Although foot and hand surgeons frequently encounter the subungual exostosis, exostoses commonly localize to other areas of the skeleton as well. In this review, we describe the clinical and diagnostic imaging characteristics of benign bone tumors and, in particular, the osteochondroma and its surgical management. We also report the case of a patient who experienced an unusual pedal digital osteochondroma-like lesion.

A calcaneal osteochondroma with recurrence in a skeletally mature patient: a case report

Introduction

Osteochondroma is the most common benign tumor of the skeleton. However, calcaneal osteochondroma is very rare. Osteochondromas grow during childhood through adolescence, but usually growing ends when the epiphyseal plates close. In an adult, growth of an osteochondroma suggests the diagnosis of malignant transformation to a chondrosarcoma. However, enlargement of an osteochondroma reported as benign after skeletal maturity is present in literature.

Case presentation

We report the clinical and radiologic findings of a calcaneal osteochondroma with an extremely rare placement and painfull, rapid reccurence following surgical excision in a skeletally mature female. The lesion showed growth the first-operation later and was re-operated. Histopathological examination did not show malignancy.

Conclusion

It should kept in mind that benign osteochondromas can show symptomatic growth in skeletally mature patients without malignant transformation.
