We report a case of a 55-year-old woman with chronic renal failure and secondary tumoral calcinosis with rare intraosseous penetration of the humerus. Typical lobulated calcifications with associated layering "milk of calcium" were present about the right shoulder and elbow on conventional radiographs, computed tomography images and magnetic resonance images. Rare appearance of cortical destruc...

Introduction: Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare malignant lesion arising within the jawbones, without initial connection with the oral mucosa. This malignant lesion develops from odontogenic epithelium or odontogenic cysts or tumors. Case Report: In this case report, an intraosseous squamous cell carcinoma arising from an odontogenic cyst in a 60-year-old male pati...

Intraosseous schwannomas is a very rare neoplasm, and less than 50 cases have been reported in the medical literature. In this article, the clinical, radiographic and histopathologic appearances of a rare case of intraosseous schwannomas are presented. The importance of this case is that other benign central lesions such as odontogenic tumors and cysts might be included in differential diagnosi...

An 8-year-old boy presented with an osteolytic lesion at the fourth metatarsal of the right foot. He received a surgical excision. Microscopically, the tumor was composed of lobules of capillary sized vascular channels with occasional dilated crescent-shaped openings at the periphery. Intraosseous hemangioma accounts for approximately 1% of all primary bone tumors. Furthermore, it is especially...

The nasal cavity harbors an enormous variety of neoplasms, including epithelial and mesenchymal tumors. Hemangioma is an infrequent mesenchymal tumor of the nasal cavity, mostly arising in the mucosa and rarely in the bones. We describe the case of a 73-year-old woman who was referred to our hospital with a tumor in her left nasal cavity. The tumor originated from the left inferior turbinate. H...

A 42-year-old, gravida 1, para 0 woman was induced at a gestational age of 41 weeks because of post-term dates. The fourth stage of delivery was complicated by a massive hemorrhage. The uncontrollable persisting amount of blood loss led to hypovolemic shock and cardiopulmonary arrest. Lifesaving extra access was gained through an intraosseous needle in the proximal tibia. We therefore advocate ...

Intraosseous vascular lesions are rare conditions, comprising only 0.5 to 1% of all intraosseous hemangioma tumors. They mainly occur in the second decade of life especially in female. The most common locations are the vertebral column and skull; nevertheless, the mandible is quite rare location. Hemangiomas are benign vasoformative neoplasms of endothelial origin. However, the origin of centra...

neurofibroma is an autosomal dominant disorder which has major criteria such as hyperpigmentation (cafe-au lait spots), cutaneous and subcutaneous tumors and bone deformities. in this report, a case of multifocal intraosseous neurofibroma in a 16-year-old male with right facial asymmetry, multiple unerupted maxillary posterior teeth and a previous history of infratemporal and orbital neurofibro...
