Thyroglossal duct cysts develop from remnants of the thyroid anlage that descend from the foramen cecum on the base of the tongue between the fourth and seventh weeks of development [1]. The thyroid primordium passes either anterior, posterior, or through the hyoid bone in its descent in the midline of the neck. This leaves a possibility that thyroid remnants may persist at any site along this ...

Aromatase deficiency is a rare autosomal recessive disorder characterized by impaired androgen to estrogen conversion. We report 13.5-year-old girl initially misdiagnosed as simple virilising 21 hydroxylase who presented with delayed puberty. Work-up showed aromatase due novel mutation in the gene. Estradiol replacement was associated increased growth, skeletal maturation, bone density and adip...

This pilot study analysed the outcome of open versus endoscopic curettage and bone grafting for the treatment of simple calcaneal bone cysts. A total of 26 patients were evaluated into two equal groups: group 1 was treated with traditional open curettage and bone grafting and group 2 was treated with endoscopic curettage and percutaneous bone grafting. Cyst size, operating time, length of stay,...

An aneurysmal bone cyst is rare in the patella. We report the case of a 9 year-old boy who presented with chronic pain and no previous trauma history. Treatment included curettage of the cyst and filling with a iliac bone graft. Ten months after surgery, the knee was mobile and painless and graft incorporation was good.

Editorial Black holes in bone – irresistible attractors of foreign materials? Bone has a mechanical function. A material to replace it should therefore be able to take over this function. Screws and plates do this, so literally speaking steel is really a bone replacement material. But this term is usually reserved for other materials: various calcium phosphates, calcium sulphate (actually plast...

Dermoid cysts are a type of benign periorbital tumor that is frequently encountered in children. According to New and Erich, dermoid cysts originate from dermal and epidermal inclusions along the embryonic cleft closure lines located in the head and neck [1]. Periorbital involvement accounts for more than 50% of the pediatric cases of these cysts. Periorbital dermoid cysts usually manifest as p...

The magnetic resonance imaging (MRI) features of a rheumatoid arthritic geode are presented. Development of such a cyst from before x ray diagnosis to its coalescence with the wrist joint is described. The evidence suggests that these juxta-articular cysts are not merely an intrusion of the synovial cavity into the bone marrow but start as isolated structures beneath the subchondral bone.

We observed a patient with a giant brown tumor of the iliac bone due to hyperparathyroidism. There was a risk of pathologic fracture due to huge cysts produced by bone absorption. In hyperparathyroid crisis, control of severe hypercalcemia is difficult without resection of the parathyroid gland.

We report the nonoperative treatment of a recurrent, multilevel spinal aneurysmal bone cyst by injection of 32P chromic phosphate colloid into the cyst. The patient was then followed up with serial CT examinations, which showed stabilization and progressive ossification within the lesion. The rationale, alternatives, and possible contraindications to radionuclide ablation of spinal aneurysmal b...

The acid and alkaline phosphatase activity in fluid aspirated from solitary bone cysts in six patients was measured, and large increases in the concentration of acid phosphatase were found. In some cases this increase was reflected in venous blood concentrations. The significance of these findings for the pathogenesis and the management of solitary bone cyst is discussed.
