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.

•

The combination of Secondary aneurysmal bone cyst with Benign fibro-osseous lesion is very rare.

•

The diagnosis of this case cnfirmed by histopathological results.

•

The open surgery is the best treatment for this rare case.

•

The doctor must follow_up patient,s condition after sugery.

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.

A child with Ewing's sarcoma in scapula: A rare case report

Introduction

Ewing's sarcoma is considered to be the second most frequent primary sarcoma in children. It affects children and young adults with a male predominance. Ewing's sarcoma is usually found in the femur, humerus, ilium and tibia; and in extremely rare cases Ewing's sarcoma might affect the scapula. There are only 15 papers in PubMed database regarding scapular Ewing's sarcoma.

Case presentation

A 14-year-old male, with no significant medical or surgical history, presented with a swelling in the right scapular area for two months. The patient also experienced mild pain and fever. On physical examination, there was a tender mass and restriction in the right shoulder joint movements. MRI showed a large scapular mass with the characteristics of a sarcoma. The final diagnosis was made based on pathologic findings. Eventually, the patient was subjected to neoadjuvant chemotherapy.

Discussion

The most common tumors affecting scapula are chondrosarcoma and osteosarcoma. In a cohort study about patients diagnosed with ES between 1988 and 2018, only 29 cases were involved in the scapula. There are 12 cases of congenital ES have been reported in the medical literature, 3 of them were in the shoulder girdle. Surgery with neoadjuvant chemotherapy is considered better for total survival in ES of scapula in comparison with chemotherapy and/or radiotherapy alone.

Conclusion

Ewing sarcoma is extremely rare in the scapula and should be considered as a differential diagnosis for any patient with scapular tumor.

•

The most common tumors affecting scapula are chondrosarcoma and osteosarcoma.

•

In extremely rare cases, Ewing’s sarcoma (ES) might affect the scapula.

•

Surgery with neoadjuvant chemotherapy is considered better for total survival.

•

ES should be considered in each child presents with a swelling over scapular region.
