purpose : to present a case of missed intraorbital wooden foreign body presented as soft tissue mass case report : we introduce a case of intraorbital wooden foreign body which presented with orbital soft tissue mass two years after trauma. a plain ct was requested which revealed a foreign body in the right orbit.conclusion : it is frequently difficult to identify and localize organic intraorbi...

An ameloblastic fibroma (AF) is a proliferative mixed tumor which includes components of both odontogenic epithelium and mesenchymal tissue. It relatively rare neoplasm, accounting for approximately only 1.5－4.5% tumors. This case report describes an AF that occurred in the mandibular anterior tooth region 9-year-old girl who presented with chief complaint swelling left region. Intraoral examin...

We describe two cases of florid, foreign body granulomatous reaction occurring in the upper arms of males in their eighth decade, who were undergoing treatment with depot injection of leuprorelin acetate for prostatic carcinoma. These patients presented with rapidly enlarging extremity soft tissue masses and were referred to a tertiary sarcoma center with clinical suspicion of a primary soft ti...

Sarcomas involving the lung are a rare occurrence, often a result of metastatic disease from primary malignancies involving the skin, liver, breast or heart. Primary pulmonary artery sarcomas are rarer still, with limited cases reported world-wide and consequently data regarding treatment modalities are sparse and largely experimental. These tumors are often mistaken for a pulmonary embolism an...

Synovial sarcoma (SS) is a rare malignant neoplasm that arises most commonly in joint capsules and articular tendons, but its relationship to the synovium is not always obvious. Synovial sarcoma is a malignant soft tissue tumor representing 5.6% to 10% of all soft tissue sarcomas. They are termed SS because of their histologic resemblance to the synovium, but they rarely involve a synovial stru...

Any medical diagnosis should take a multimodal approach, especially those involving tumour-like conditions, as entities that mimic neoplasms have overlapping features and may present detrimental outcomes if they are underdiagnosed. These case reports present diagnostic pitfalls resulting from overdependence on a single diagnostic parameter for three musculoskeletal neoplasm mimics: brown tumour...

Background:   Although the majority of soft tissue masses are benign, it is important to consider malignancy in differential diagnoses. Because most soft tissue sarcomas present as a painless mass, clinicians must watch for signs suggestive of malignancy, including large size, rapid growth, and site deep into the deep fascia.The purpose of this study was to determine the relative prevalence acc...

Received March 2008 Accepted September 2008 INTRODUCTION Angiosarcoma is a rare high-grade malignant tumor accounting for less than 2% of the soft tissue sarcomas.(1) They originate from the endothelium of the blood and lymphatic vessels and can be primary or metastatic, and localized or multicentric. Most angiosarcomas develop in the skin or soft tissue, and others, in the breast, liver, and b...

Osteochondromas are common and typically arise from the metaphyseal ends of long bones. An osteochondral neoplasm of the soft tissue, which is a lesion of uncertain pathogenesis, is uncommon and usually arises from the synovial tissue in joints and tendon sheaths. Rarely, extraskeletal osteochondromas also arise outside of synovial compartments. Most of the reported cases were presented in the ...

Orbital metastasis is a rare occurrence found only in about 3 - 10% of all prostate cancers. A 72 years male presented with proptosis of the left eye associated with pain, blurred vision and frequent headaches for the past 8 months. Past medical history had symptoms of bladder outflow obstruction for 3 years. MRI brain and orbit with contrast was consistent with a large soft tissue mass in the ...
