arcomas are rare tumors, representing only 0.8% of new cancers in the United States. Seventy-six percent arise in soft tissue, with the remainder arising in bone (1). The most common soft tissue type is malignant fibrous histiosarcoma, although this has fallen out of favor recently as a distinct histologic entity (2, 3). Multiple types of soft tissue sarcomas are defined based on the tissue of ...

A 77-year-old male presented to the emergency department with a 2-day history of increased swelling and pain in the left knee and distal thigh. He was unable to extend the knee without severe pain. On examination, the patient had a large pulsatile mass in the left popliteal fossa and distal thigh. Which of the following is the initial diagnostic test of choice for popliteal artery aneurysm? A. ...

ically benign mass that is characterized by a variably cellular, spindle cell proliferation in a myxoid to collagenous stroma with a prominent inflammatory infiltrate that is primarily composed of plasma cells and lymphocytes, with occasionally admixed eosinophils and neutrophils (1). Inflammatory myofibroblastic tumor most commonly involves the lung and the orbit, but it has been reported to o...

Using data from the Third National Health and Nutrition Examination Survey (NHANES III), conducted from 1988-1994, we investigated the effect of reproduction on the distribution of body fat in well-nourished American women. While women tend to gain weight and fat with succeeding pregnancies, if age and body mass index are controlled, increasing parity is associated with a decrease in hip and th...

A mathematical model is presented to determine tissue temperature in the periphery of human thigh during moderate(23°C) and cool(15°C) environment temperature and the effect of sweat evaporation on heat loss from human body is also measured. The region under study is a circular cross-section of human thigh and further has been partitioned into three concentric tissues layers on the basis of bio...

Ossifying fibromyxoid tumor (OFMT) is a soft tissue tumor of uncertain lineage that most often arises in the extremities of adults. Imaging findings of this uncommon tumor are rare. We, herein, present a case of OFMT occurring in the left thigh of a 36-year-old male. Radiological examinations revealed a well-circumscribed subcutaneous mass with an incomplete shell of peripheral ossification, su...

In the advent of increasing demand for total hip arthroplasty, surveillance of these patients is imperative to identify potential complications requiring revision surgery. This is especially important in the young population, as revision is usually necessary during their lifetime. We present a case of a young female patient with a history of total hip arthroplasty 17 years prior, who presented ...

PATIENT Female, 32 FINAL DIAGNOSIS: Intraosseous lipoma Symptoms: Swelling of the thigh Medication: - Clinical Procedure: Excision of the mass Specialty: Surgery. OBJECTIVE Rare disease. BACKGROUND Intraosseous lipomas happen to be one of rarest benign soft tissue tumors with only a little known about its etiology and pathophysiology. A pubmed search using key word "Intraosseous lipoma". Ca...

As reported previously, the 61-year-old male Chinese patient suffering from the inflammatory myofibroblastic tumor of the right thigh without bone involvement was performed a surgical excision and a local radiotherapy two years ago. However, a moderately soft and painful 200 × 100 mm mass of the posterior thigh, where magnetic resonance imaging (MRI) scans revealed an inhomogeneously hyperinten...

BACKGROUND Quantifying the improvements in lower limb or quadriceps muscle mass following resistance training (RT), is an important outcome measure in COPD. Ultrasound is a portable, radiation free imaging technique that can measure the size of superficial muscles belonging to the quadriceps group such as the rectus femoris, but has not been previously used in COPD patients following RT. We com...
