UNASSIGNED: Angiolipofibroma is rare lesion with extraordinarily vascular structure, occurs within the head and neck region, typically springing up in the nasopharyngeal location, with a locally competitive efficiency.
METHODS: Male patient, aged 25 years old was referred to oral surgeon with the aim of surgical removal of a painless lesion of the left posterior mandibular area. he has well heath without any medical history The mass was removed by the oral surgeon and subjected to histological analysis the final diagnosis was found to be an intraosseous angiolipofibroma.
UNASSIGNED: The significance of this report lies in the rarity of the presence of angiolipofibroma in the mandible and the clinical and radiographic manifestations were only a silent unilocular radiolucent lesion. Only a few cases have been published describing angiolipofibroma in the mandible. it is difficult to diagnose on clinical and radiographic features only.
CONCLUSIONS: The definitive diagnosis is based on histological examination. The surgical treatment was enough.

Large subchondral bone cysts in the medial talar body and dome are common and can cause persistent pain and swelling during axial loading. Open debridement and bone grafting are often necessary to treat these lesions but can require extensive soft-tissue dissection or malleolar osteotomies. A 40-year-old woman presented with ankle pain and swelling for 1 year, worsening with activity and no history of trauma. X-rays showed a cystic lesion in the medial talar dome with no joint line disruption. CT confirmed the cystic lesion without bone collapse or expansion. An anterior approach to the ankle joint was extended to access the talar neck. A window was created in the talar neck to debride and curette the medial talar dome, and the void was filled with allograft. The patient was non-weight-bearing for 6 weeks, followed by gradual weight-bearing and ankle range of motion exercises starting on postoperative day 1. The patient returned to her pre-injury status within 3 months and was asymptomatic at the 6-year follow-up, with good bone graft integration and no symptoms. This technical note presents a novel approach to lesions of the medial talar body and dome through the talar neck, avoiding the need for malleolar osteotomy or disruption to the tibiotalar joint, and resulting in good functional outcomes.

BACKGROUND: The intraosseous schwannoma (IS) is a benign peripheral nerve sheath tumor postulated to arise de novo or from nerve fibers in preexisting nutrient canals. ISs are uncommon and comprise less than 1% of neoplasms originating in bone. We herein present two cases of mandibular schwannomas-the first case was a 66-year-old female with a four-month history of pain and pressure associated with an anterior mandibular radiolucency, and the second case was an asymptomatic 12-year-old female with separate radiolucencies of her mandibular symphysis and right posterior mandible. Incisional biopsies of all three lesions showed a benign spindle cell neoplasm with histologic features of a schwannoma; the tumor cells were strongly reactive for S-100. The patients underwent complete enucleation of their lesions and are without evidence of disease at ten months and five years, respectively.
METHODS: A systematic review was undertaken to evaluate the diagnostic features, treatment, and patient outcomes of gnathic schwannomas.
RESULTS: A total of 93 cases were identified with the following demographic findings: predominance in females (57%); average age of occurrence of 37.3 years (8 to 77 years); mean size of 3.6 cm; and involvement of the mandibular body (37.6%), mandibular body and ramus (18.3%), and anterior mandible (18.3%). The predominant clinical sign was swelling (69.9%), and the most common radiographic presentation was a radiolucency (94.6%) with well-defined borders (72%).
CONCLUSIONS: All cases were treated surgically, with an average follow-up interval of 22.9 months and a recurrence rate of 5.4.

Intraosseous hemangiomas are rare tumors. A 43-year-old woman was referred with a mass in the right zygomatic bone, showing a slow volume increase and pain symptomatology. A surgical management with bone reconstruction using a custom-made implant was decided. Historically, various autografts and alloplastic materials have been used for this type of bone loss. The use of custom-made biomaterials opens new possibilities in maxillofacial reconstructive surgery. The patient showed no symptoms postoperatively and her zygomatic bones were symmetrized. For the authors, this approach seems to be a reliable and reproducible method for zygomatic bone reconstructions.

Ectopic cerebellar tissue has only been described in isolated case reports, with only two reported cases in adult patients. We report the case of a 63-year-old woman with progressive, medically refractory headaches. A scan showed an intraosseous lesion of the midline occipital bone. Surgical resection of the soft tissue lesion was undertaken. Her headaches ceased postoperatively. Histopathological analysis revealed cerebellar cortical tissue with a surrounding meningothelial cell layer, characteristic of cerebellar ectopia. This is the second reported case of an intraosseous location of this lesion, and only the third case described in an adult patient. Our findings illustrate a rare cause of headaches and support the therapeutic roles of surgical treatment for this extremely rare condition.

BACKGROUND: Ectopic cerebellar tissue located distantly from the normal cerebellum is very rare, and its pathophysiology remains to be elucidated.
METHODS: We report an extremely rare case of intraosseous ectopic cerebellum detected incidentally at suboccipital craniotomy in a 46-year-old Japanese woman with hemifacial spasm. She had a small bone defect in the occipital bone, which contained a tiny area of soft tissue surrounded by cerebrospinal fluid connecting to the normal subarachnoid space through a dural opening. Histopathology demonstrated cerebellar cortex tissue consisting of molecular and granular cell layers.
CONCLUSIONS: This is the first report of glioneuronal ectopia within the skull bone separated from normal brain tissue, and it is important to distinguish this entity from other osteolytic lesions.

Giant cell reparative granuloma (GCRG) is benign, non-tumorous granulation tissue. It mainly arises in the jaw bone and occasionally in the hand and foot. Because of the high rate of recurrence, wide surgical resection and autologous bone grafting are recommended. However, this can be problematic for hand function. We present a case report of a 16-year-old boy with a GCRG of the fifth metacarpal bone and the diagnostic difficulties. To treat the patient, we performed a wide resection with the interposition of a corticocancellous bone graft and plate osteosynthesis. 24 months postoperatively the patient shows no signs of recurrence and has good hand function.

Intraosseous Arteriovenous Malformations (AVMs) in the head and neck region are very rare and potentially life threatening entities due to massive hemorrhage. These are the results of an embryonic abnormality of the vascular system. Depending on the blood flow and clinical presentations they are of different types like slow flow and high flow AVM. Here we present a case of high flow AVM involving mandible with a chief complain of gingival bleeding in a four year old girl child.
