Aneurysmal bone cyst (ABC) is a benign, expansile, non-neoplastic lesion of the bone, characterized by channels of blood and spaces that are separated by fibrous septae. Giant ABC is an uncommon condition and can be difficult to handle because of the destructive effect of the cyst on the bones and the compressive effect on the nearby structures, especially in weight-bearing bones of the body. W...

juvenile ossifying fibroma (jof) is a rare, benign, locally aggressive entity of the extragnathic craniofacial bones with a high tendency towards recurrence. two distinctive microscopic patterns of juvenile ossifying fibroma have been described: a trabecular juvenile ossifying fibroma (trjof) and a psammomatoid juvenile ossifying fibroma (pjof). psammomatoid variant is predominantly a craniofac...

The glandular odontogenic cyst (GOC) is a rare lesion with odontogenic origin. It shows a propensity for recurrence revealed in 30% of all case. This investigation reports a case of recurrent GOC in a 35-year-old female in the anterior region of the maxilla, which is uncommon and discusses about IHC finding, surgical methods, and differential diagnosis. Under general anesthesia, peripheral bone...

H cyst can involve many systems, mainly the liver and lungs. The liver is the location of 50-70% of Echinococcus granulosus (EG) cysts while 10-30% are in the lungs and 10% in other regions of body. The spinal and cranial regions are rare areas of involvement. Bone involvement is seen in 0.5-4% (8). Bone lesions are most frequently localized at the spine and pelvis. There is no cyst membrane an...

Introduction: Giant cell tumor (GCT) is a distinctive lesion characterized by the proliferation of multinucleate giant cells in stroma mononuclear cells; it generally seen skeletally mature individuals. GCT usually found long bones around knee or distal radius but end tibia, proximal humerus, vertebrae young adults are unusual location. We report case with secondary aneurysmal bone cyst, 26-yea...

Extramedullary hematopoiesis (EMH) is a phenomenon in which hematopoietic cells are found in sites other than the bone marrow. It is usually observed in the liver and spleen but may occasionally be found within solid tumors. The current case report presents a 69-year-old female patient who presented with a renal cyst. Histopathological examination following surgical removal of the cyst revealed...
