Familial Adenomatous polyposis (FAP) it is based on an autosomal dominant mutation which results in loss of function of theAPC tumor suppressor gene. On the other hand, Gardner syndrome is a type of FAP and is characterized for multiple colonic adenomatous polyps and extracolonic abnormalities as desmoid tumors, osteomas, lipomas, dental abnormalities, dermoid cysts and duodenal adenomas. This report aims to present two patients with FAP: The first one is a patient who presented with osteomas and hematochezia, being diagnosed with Gardner Syndrome after the colonoscopy...

A 10-year-old girl presented with episodes of migraine. A nasal mass was found randomly during work-up. Interpreted as an osteoma, the mass was removed during endoscopic surgery. However, the histopathological examination turned out to be a pyomucocele in the right middle turbinate, which is an extremely rare yet benign condition in children.

Temporal bone osteoma is an unusual pathology which can occur by birth or can be acquired and mostly involves the tympanomastoid segment of the temporal bone. Osteomas arising from the otic capsule are extremely rare, and there has been only one other report of a lateral semicircular canal osteoma in the literature. We report a similar case of an acquired lateral canal osteoma which presented as a chronic postaural fistula in an ear previously operated for paediatric cholesteatoma.

Joe M Das
In this occasion of 125 years after the so-called "initial" use of bone wax (BW) by Sir Victor Horsley, a review of this age-old hemostatic agent deemed appropriate. The first use of BW for hemostasis is dated back to the 18th century when modeling or candle wax was used for hemostasis. Though the pioneers in the usage of BW in craniofacial surgeries were Belloq, Professor Khristian Khristianovich Salomon and François Magendie, its first successful use in neurosurgery was demonstrated by Henri Ferdinand Dolbeau in 1864, following the extirpation of a frontal osteoma...

RATIONALE: Metachondromatosis (MC) is a very rare genetic disease, which is infrequently reported worldwide, which leads to osteochondroma and enchondromatosis. The disease has been shown to be associated with loss of function of the tumor suppressor gene "protein tyrosine phosphatase, non-receptor type 11" (PTPN11). PATIENT CONCERNS: A 12-year-old female was admitted to the hospital with pain due to an enlarged mass in her left fifth finger. DIAGNOSIS: Examination of the left hand by computed tomography (CT) revealed an expanding type of round and low-density lesion in the fifth proximal phalanx...

Interventional radiology has experienced an exponential growth in the last years. Nowadays it is possible to treat painful benign lesions or metastases with optimal results in terms of pain management and disease control. Among the benign lesions, osteoid osteoma is the most frequently treated with minimal invasive techniques and the results are excellent. Another lesion, traditionally treated with surgery (osteoblastoma) represent today another field of application. In the oncological field, metastases are, numerically, the most diffuse indications for treatment...

BACKGROUND: Paranasal sinus osteoma is a common, asymptomatic, histologically benign, and slow-growing tumor. However, it can give rise to secondary pathologies such as a mucocele in about 50% of the cases. Rarely, intracranial and orbital extension is present leading to rhinoliquorrhea, pneumocephalus, or neurological and visual impairment, which might be potentially life-threatening. CASE DESCRIPTION: A 49-year old man presented with an acute frontal lobe syndrome and rhinoliquorrhea...

BACKGROUND: With the exception of osteomas, bone neoplasms that originate in the sinonasal cavity are seldom diagnosed on preoperative imaging due to a lack of characteristic radiographic features. Here we described the unusual occurrence of an osteoblastoma in the paranasal sinuses, and we drew focus to its salient imaging features. A highly unique imaging sign was indicated, and its pathologic basis was explained, with concurrent review of the literature. METHODS: Case series and review of the literature...

Introduction: Proximal femur is the common site for localization of benign bone lesions, and the diagnosis is often delayed and potentially challenging due to their atypical presentations. Early diagnosis is difficult as intra-articular lesions often present with clinical and radiological features of inflammatory synovitis in the joint. Case Report: Two patients of intra-articular osteoid osteoma in proximal femoral presented with atypical features limb lengthening, minimal reactive bone sclerosis, and multifocal nidus...

Choroidal osteoma (CO) is a rare, benign, and usually unilateral intraocular tumor composed of mature bone affecting the choroid. It appears as slightly elevated, yellowish-white, or orange choroidal mass with well-defined borders. It is commonly encountered in young female adults. Here, we report findings of a 4-week-old premature baby with CO in her left eye which was detected during a routine examination for "retinopathy of prematurity." We believe that this case is the youngest patient reported with CO which showing that this pathology can be encountered even in a newborn...

It has been believed for a long time that the Paduan scholar Antonio Vallisneri (1661-1730) described the second historical case of the frontal sinus osteoma in 1733. By historico-medically reexamining this case, we conclude that the brain concretions he described were not a case of frontal sinus osteoma, while they appear to have been pathological outcomes of neurocysticercosis, whose larval stages would only be described by Johann Goeze (1731-1793) later, in 1784. Thus, this case becomes relevant for the history of neuroparasitology...

BACKGROUND: There are many options for the reconstruction of frontal sinus wall defect resulting from injury, neoplastic lesions and aesthetic deformities. These mainly include autogenous grafts, allogenous grafts, and alloplastic materials. The aim of the present study is to report the advantages of using autogenous calvarial bone grafts over other reconstruction techniques, in the reconstruction of frontal defects. METHODS: We describe 16 consecutive cases of anterior frontal sinus defects between 2004 and 2015, in which calvarial bone grafts were used...

Pai syndrome is a very rare congenital disorder characterized by medial cleft lip, nasal and facial cutaneous polyps, and pericallosal lipoma. Broad phenotypic variability exists in this condition. Neurodevelopment is usually normal. Up to date 42 cases have been reported in the literature. Different types of inheritance have been proposed, but most cases are sporadic. No gene has been identified. We report two cases with Pai syndrome, one of them with novel clinical findings as vertebral segmentation defects and choroidal osteoma...

Osteoid osteomas are benign bone tumors which rarely occur in the hand and impose severe diagnostic problems. The course of the disease is often protracted before the patient receives an adequate surgical treatment. The case of an osteoid osteoma in the scaphoid bone of a 15-year-old patient is presented, who was completely symptom free after a true diagnostic odyssey by resection of the nidus and reconstruction by crest bone graft and spongiosaplasty.
