A Case Report of Chondromyxoid Fibroma of the Neck of Femur, Intracapsular Location

Abstract

Introduction: Chondromyxoid fibroma (CMF) is an uncommon benign tumor accounts for <2% of all benign and <1% all bone tumors. It is a cartilage tumor with myxoid and fibrous elements. Because of rarity and resemblance with other benign and malignant tumor, diagnosis of this tumor always remains challenging. Often, this lesion affects metaphysis of long growing bones of children and young adults. Common locations of this tumor are around the growth plate of proximal tibia and fibula and distal femur. Case Report: A 21-year-old male presented to orthopedic outpatient department with a history of the left hip pain for 1 year, following a trivial fall before 1 year. The patient was not able to do heavy strenuous activities such as running, jumping, and other sports activities. Terminal range of movements were painful. Magnetic resonance imaging suggested of cystic lesion involving synovial lining near head-and-neck junction of the left femur. Curettage of the lesion was done. The bone defect was not found to be large enough to be filled with bone graft. Histopathological examination showed lobular pattern with stellate to spindle-shaped cells on the myxoid background. Conclusion: CMF of subcapital region of femoral neck is an extremely unusual presentation. When occurring in middle-aged persons and in uncommon locations, this can raise suspicion of chondrosarcoma. Although intralesional curettage has the risk of recurrence in post-operative period, sufficient and careful curettage and excision of lesion will be enough to treat these benign lesions with good prognosis. Keywords: Chondromyxoid fibroma, intracapsular, benign tumor.

Garré’s Sclerosing Osteomyelitis of the Tibia in a Hispanic Adult Male: A Case Report

“…Meanwhile, laboratory results often show elevated levels of inflammatory markers such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) [4]. Radiographic imaging commonly presents with reduced medullary canals and stiffened cortices [10]. Isotope scans may show increased uptake at the involved site [1].…”

A Rare Encounter With Garre’s Osteomyelitis of the Proximal Tibia: A Case Report

“…It is common in young adults and children but is rarely observed in individuals >40 years of age or later. Though there are cases reported for the same [2,[6][7][8]. The clinical presentations associated with Garre's osteomyelitis are bone inflammation or bone swelling, dental infections noted with facial asymmetry, asymptomatic swelling, or insidious pain [6,8,11,12].…”

“…Though there are cases reported for the same [2,[6][7][8]. The clinical presentations associated with Garre's osteomyelitis are bone inflammation or bone swelling, dental infections noted with facial asymmetry, asymptomatic swelling, or insidious pain [6,8,11,12]. Cases with femur and tibia infections have also been available in the published literature, usually of >25 years of age [11].…”

“…Surgical intervention might be considered in cases of poor disease control, followed by a long-term antibiotic regime to avoid recurrence. Fenestration and curettage at the afflicted spot are reported to be used in surgical management [4,8,10]. Spiral CT has been reported as the most accurate imaging modality in research involving 121 patients in the diagnosis of limb osteomyelitis.…”

“…Surgical intervention is required in cases of inadequate disease control. Options for surgery include the removal of the chronic osteomyelitis-affected area to expose the medullary canal and debride the damaged bone [8][9][10]. This case report of a 47-year-old female highlights the importance of timely intervention and interdisciplinary teamwork regarding diagnosis and management.…”
