RATIONALE Solitary fibrous tumor (SFT) is a rare benign soft tissue mesenchymal neoplasm. There have been a few reports of extrapleural SFTs although it can occur anywhere in the body. PATIENT CONCERNS A 30-year-old male presented with an anterior neck mass since one month. DIAGNOSES Based on physical and radiologic examination, preliminary differential diagnosis was thymic neoplasm or intr...

background: within the context of developing techniques to facilitate the diagnosis of the thyroid diseases, the elemental composition of pathological thyroid tissue (neoplastic and non-neoplastic) was investigated by proton induced x-ray emission. the pixe has been widely used as a sensitive technique for trace elemental analysis in both biological and medical fields. materials and methods: th...

Rhabdomyosarcoma (RMS) is a malignant skeletal muscle neoplasm. RMS can occur anywhere in the body and is the most common childhood sarcoma (1). Pediatric RMS is an aggressive neoplasm with deregulated cell cycle checkpoints, high genome instability, and oncongene ampli ication such as MYC family members (2). However, RMS rarely occurs in adults. Moreover, sarcomas of the kidney are rare soft t...

BACKGROUND Klippel-Trenaunay syndrome is a non-heritable venous malformation with bone and soft tissue hypertrophy and cutaneous nevi. CASE CHARACTERISTICS Neonate with Klippel Trenaunay syndrome born to a mother with past history of Gestational trophoblastic neoplasm. OBSERVATION Antenatally, a fetal vascular malformation was identified ultrasonologically at 29 weeks gestation. Acute myelo...

Lateral disk herniation into the intervertebral foramen if not recognized may result in a negative surgical exploration. The condition is readily recognized by computed tomography (CT), which demonstrates a soft-tissue mass in the intervertebral foramen, focal protrusion of the posterolateral margin of the disk into the foramen, absence of dural sac deformity, and occasionally the presence of c...

Malignant fibrous histiocytoma (MFH), a type of sarcoma, is a malignant neoplasm of uncertain origin that arises both in soft tissue and bone. We present a case of MFH in a 18-year-oldfemale patient with swelling on the left maxillary posterior region .This paper demonstrates the malignant character of this neoplasm. CT scans revealed a clouding lesion in the left maxillary premolar and molar r...

Synovial sarcoma is an uncommon neoplasm accounting between 8 and 10% of all soft tissue malignancies. Involvement of the head and neck region is rare. So far, fewer than 100 cases have been reported in the literature and only a few originated in the soft palate, tongue, larynx, hypopharynx, and cervical oesophagus. We report the case of a synovial sarcoma of the parapharyngeal space in a 72-ye...

Malignant epithelioid hemangioendothelioma (MEH), also known as high-risk epithelioid hemangioendothelioma, is a low- to intermediate-grade vascular malignancy originally described as a vascular neoplasm of endothelial origin. This very rare vascular neoplasm has been described mainly in soft tissue, but also in various organs and locations, including the liver, lung, brain, colon, lymph nodes,...

statement of the problem: most of the soft tissue calcifications within the head and neck region might not be accompanied by clinical symptoms but may indicate some pathological conditions. purpose: the aim of this research was to determine the prevalence of soft tissue calcifications in cone beam computed tomography (cbct) images of mandibular region. materials and method: in this cross sectio...
