Conventional surgical approach for cyst enucleation is removal of buccal compact bone plate, which often results in remarkable bone loss and subsequent mucosal recession. This report presents one case of residual mandibular cyst enucleation and one case of apicoectomized mandibular molar, both treated with the bony lid approach. A window of buccal compact bone was precisely created using an ele...

Aneurysmal bone cyst is a rare benign tumor of the bone that can be difficult to distinguish from malignant tumors, especially when it presents in an unusual location. Herein, we report a six-year-old girl with a primary aneurysmal bone cyst in an uncommon location. It originated from the 4th rib and she presented with a huge chest wall mass. Despite the large size of the cyst, the only symptom...

Background: Persistent thyroglossal duct leads to a fibrous cyst formation named thyroglossal cyst which is the most common form of congenital cyst and usually located in the midline neck below the hyoid bone. Rarely the thyroglossal cyst is associated with thyroid cancer. Although the Sistrunk procedure is often considered adequate, currently there is no clear consensus on the optimal manageme...

UNLABELLED INTRODUCTION Nonossifying fibroma is a common fibrous bone lesion in children that occurs in the metaphysis of the long bones of the lower extremities. The lesion rarely leads to aneurysmal bone cyst, which is characterized as a blood-filled space. CASE PRESENTATION We present the case of a 13-year-old Japanese boy with a complaint of discomfort in the thigh and a small, well-de...

INTRODUCTION Aneurysmal bone cyst is a rare, rapidly growing, and destructive benign bone tumor that rarely involves the bones of the hand. Various treatment options for aneurysmal bone cyst have been reported in the literature, but controversy exists regarding optimal treatment. CASE REPORT A six year old boy presented with a history of pain and local swelling over his third metacarpal of fi...

Aneurysmal bone cyst is a benign fibro-osseous lesion usually described in the long bones. Intraorbital aneurysmal bone cyst is a rare clinical entity with an entirely different outcome and prognosis as compared to the usual pediatric orbital tumors. The authors report magnetic resonance imaging (MRI) features of an orbital mass lesion in a 4-year-old child who presented with painless proptosis...

Incidence of simple renal cysts was calculated in 30,316 patients receiving routine ultrasound examination in one hospital, and 170 cases visiting Chiba University Hospital were further analyzed in terms of their clinical features. Incidence of simple renal cyst was 14% in all populations and ratio of male to female was 1.6:1. Patients age ranged from 8 to 92 years (average age 58.6 years) and ...

Unicameral bone cysts (UBCs) are benign lesions predominantly affecting children and teenagers. This case report highlights the rare occurrence of a simple cyst in proximal radius 29-year-old woman with pathological fracture. Although is an uncommon site for UBC occurrence, surgical approach required special care due to complex anatomical structures near fracture site. The management UBCs aims ...

BACKGROUND Simple bone cysts (SBC) have been documented to occur in adults with closed physeal plates, most commonly affecting the calcaneus in this patient subset. Although most authors theorize an association to trauma, etiology of simple bone cysts remains an enigma up to now. CASE PRESENTATION A 26-year-old kickboxing coach sought consult for a painful right shoulder which on radiographs ...

BACKGROUND Aneurysmal bone cyst was first described by Jaffe and Lichtenstein in 1942. Schajowicz in 1972 in his Histopathological Classification of Primary Bone Tumors (later modified by WHO in 1993) placed it in group IX - tumor-like lesions. Its etiology and pathogenesis is not completely clear. Aneurysmal bone cysts are usually found in older children and young adults, rarely before the age...
