We describe the first definitive case of a fibrous dysplastic neoplasm in a Neandertal rib (120.71) from the site of Krapina in present-day Croatia. The tumor predates other evidence for these kinds of tumor by well over 100,000 years. Tumors of any sort are a rare occurrence in recent archaeological periods or in living primates, but especially in the human fossil record. Several studies have ...

INTRODUCTION Solitary fibrous tumor is associated with serosal surfaces. Location in the salivary glands is extremely unusual. Extrathoracic tumors have an excellent prognosis associated with their benign clinical behavior. We report an aggressive and recurrent case of this tumor. We review the clinical presentation, inmunohistochemical profiles and therapeutic approaches. CASE REPORT A 73-ye...

BACKGROUND Solitary fibrous tumors of the middle mediastinal space are uncommon and often not discovered until symptoms secondary to compression of adjacent structures occur. Diagnosis requires surgical biopsy and histological tissue analysis. We describe the ECHO appearance of the solitary fibrous tumor and successful non-invasive EBUS diagnosis. This method of diagnosis allowed for surgical p...

background: tumors involving the hand skeleton are rare. however, a basic knowledge of hand tumors is necessary for every clinician. this is due to the importance of distinguishing typical benign tumors from life or limb threatening malignant ones. methods: this study is a review of 99 cases of osseous hand tumors presented to the department of orthopedic surgery, imam khomeini hospital in tehr...

Nodular fasciitis falls within the benign spectrum of fibrous soft-tissue tumors. We present a case of nodular fasciitis in the supraclavicular fossa in which an unusual angiographic presence of neovascularity is shown.

INTRODUCTION It is rare for primary tumors to arise from the mesentery. Lymphangiomas appear as congenital malformations of the lymphatic system or benign neoplasms as a large, thin-walled, often multilocular cyst. Mesenteric infiltration is common and during surgical treatment, adjustment of structures such as the bowel and resection of the spleen may be required. Cystic mesotheliomas are rare...

A solitary fibrous tumor is a relatively uncommon neoplasm that usually occurs in the pleura but occurs extremely rarely in the oral cavity. Reported herein is a rare case of a solitary fibrous tumor in the buccal cheek mucosa. A 50-year-old man visited the authors' hospital due to a buccal cheek mass whose size had increased. Excisional biopsy was done under local anesthesia. After the excisio...

introduction: desmoid tumors are very rare, benign fibrous neoplasms arise from the musculoaponeurotic structures throughout the body.   case report: the patient was a   seven-year old boy with a large mandibular mass growing over a period of six months. his ct-scan showed a large mass, 13 cm in diameter in the cheek area extending to the neck and trachea. biopsy was compatible with desmoid fib...

INTRODUCTION Paratesticular fibrous pseudotumors represent benign new growths confined to intrascrotal structures. Both pathogenesis and clinical management are little understood due to the rarity of the lesion, with less than 200 cases reported to date. Recently, paratesticular fibrous pseudotumors have been postulated to be immunoglobulin G4-related, pathogenetically. Here we report two cases...
