Secondary aneurysmal bone cyst with benign fibro-osseous lesions: Case report.

INTRODUCTION: Aneurysmal bone cyst is a controversial osteolytic benign expansive lesions which occur more frequently in the metaphysis of long bones and spine. They are classified as primary or secondary lesions depending on the presence or absence of an associated bone pathology. CASE PRESENTATION: An uncommon case has proven histological of benign fibro-osseous lesions (fibrous dysplasia and juvenile psammomatoid ossifying fibroma) with secondary aneurysmal bone cyst formation inferior and lateral to the knee for a 7-year-old female patient. The lesion was surgically removed and the patient was followed up for 6 months with excellent results without any complications. DISCUSSION: There are many cases that have previously documented a bone aneurysm cyst, but what distinguishes this case is that it is a secondary type and its association with a benign bony fibrosis. CONCLUSION: The combination of the two lesions constitutes a unique and rare case that can add to the medical literature within the orthopedic department.

Osteopoikilosis with bony deformities of the right toes in a female child: Case report.

INTRODUCTION: Osteopoikilosis (OPK) is an extremely rare benign condition with sclerosing bony dysplasia and multiple benign enostoses. OPK is usually asymptomatic and is typically an incidental finding on imaging studies for unrelated conditions. CASE PRESENTATION: We presented a case of OPK in a 7-year-old female with hallux valgus, shortening and deformity of second and third metatarsals in the right foot. These abnormalities were observed on clinical findings with X-ray imaging, and osteopoikilosjs was confirmed by histopathology. The deformities were treated with surgical intervention, and the patient's condition was followed for 3 months until the patient walked and removed the gypsum. DISCUSSION: OP is a rare, benign disease that rarely causes bony deformities. It is diagnosed clinically and radiographically, so that the deformities are treated only surgically. Follow-up is necessary to assess the movement of the limb. CONCLUSION: The distinctive thing that can be added to the medical literature is that it is possible for osteopoikilosis to cause bone deformities at an early age.
