background: this was a retrospective cephalometric study to develop a more precise estimation of soft tissue changes related to underlying tooth movment than simple relatioship betweenhard and soft tissues. materials and methods: the lateral cephalograms of 61 adult patients undergoing orthodontic treatment (31 = premolar extraction, 31 = nonextraction) were obtained, scanned and digitized befo...

Intramuscular myxoma is a rare benign soft tissue tumor which may be mistaken for other benign and low-grade malignant myxoid neoplasms. We present the case of a 63-year-old woman with an asymptomatic intramuscular myxoma discovered incidentally on a whole-body F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography. PET images showed a mild FDG uptake (maximum stan...

The nonrhabdomyosarcoma soft tissue sarcomas (NRSTSs) are a heterogeneous group of mesenchymal cell neoplasms that account for about 4% of childhood cancers. Because each histologic subtype of NRSTS is rare, they have been poorly studied and little is known about their biology, natural history, or optimal treatment. Data from adults with soft tissue sarcomas provide some helpful insight, but ad...

Glomus tumors are rare, benign, vascular painful swellings arising from glomus bodies. They represent less than 1.6% of all benign soft tissue neoplasms (1), are usually found between ages 30 and 50 years and are more common in women than men with a ratio of 2:1 (2). They are commonly seen in the subungual region of digits but ectopic locations are not uncommon (3). Other rare locations include...

Sarcomas are a heterogeneous group of malignant neoplasms arising from mesenchymal cells. They account for less than 1% of adult solid malignant cancers. The vast majority are soft tissue sarcomas, while malignant bone tumors represent only about 10% of them [1]. In fact, sarcomas comprise over 50 different histological subtypes; they may arise in stem cell-like population (primitive neuroectod...

INTRODUCTION Alveolar soft tissue sarcoma of the tongue is a very rare and aggressive tumor which occurs in infancy with a relatively controversial histogenesis. It may mimic benign vascular neoplasms and may metastasize to the lungs, brain or bones. CASE PRESENTATION We present the case of a three-year-old Caucasian boy who was admitted to our department with a history of dysphagia and two e...

Mast cell activation syndrome (MCAS) is a relatively recently recognized cause of chronic multisystem polymorbidity of a generally inflammatory theme. Patients with MCAS often report migratory soft tissue and/or bone pain which frequently responds poorly to typical (narcotic and non-narcotic) analgesics as well as atypical analgesics such as antidepressants and anticonvulsants. Hydroxyurea (HU)...

Synovial sarcoma (SS) is one of the more common soft tissue sarcomas among young adults, accounting for 10 % of this group of malignant tumors. It arises mainly in deep soft tissue in the extremities, but a small number have been reported in other anatomical locations (Enzinger and Weiss, 2000). By definition, sarcomas are malignant neoplasms of mesenchymal origin, displaying a variety of diffe...

The aim of this study was to evaluate the relative frequencies, types and distribution of benign oral masses in North Jordanians. The records of the Department of Pathology at Jordan University of Science & Technology were reviewed and analyzed for patients with benign oral soft tissue masses, received during an 11-year period (1991-2001). The main outcome measures were patients' age and sex, a...
