Recurrent Malignant Fibrous Histiocytoma in Psoas Muscle: A Case Report

Malignant fibrous histiocytoma is one of the most common sarcomas that occur in soft tissue, it usually develops in old age individuals and the incidence is similar between the genders. We report here on a case with invasive local recurrence after surgical resection of a malignant fibrous histiocytoma that occurred in the left psoas muscle of a 69-year-old male patient. The patient was first admitted to our hospital with a primary lesion in the left lower abdomen, as seen on magnetic resonance imaging. We report here on a rare case of a malignant fibrous histicytoma in the psoas muscle.

A Large Symmetrical Esophageal Ulcer Caused by Thermal and Compressive Injury from a Solid Foodstuff Known as 'Song-Pyen' / 대한내과학회지

There are many possible causes of esophageal ulcer, such as reflux esophagitis, pill-induced esophagitis, infectious esophagitis, tuberculosis, syphilis, Behcet's disease, radiation injury, caustic injury, foreign body-induced injury, esophageal cancer, and so on. However, there are only a few cases of esophageal ulcer by thermal injury from food, and most of these were caused by liquids; few are related to ingestion of solid food. We experienced a case of a large symmetrical esophageal ulcer caused by thermal and compressive injury from a hot solid foodstuff known as 'Song-pyen', a traditional Korean food, and report the natural course of healing by conservative treatment, with a review of the few available reports regarding such injuries.

Treatment of Refractory Lateral Epicondylitis with Platelet-Rich Plasma

PURPOSE: To evaluate clinical results of a single percutaneous injection of platelet-rich plasma in patients with refractory lateral epicondylitis. MATERIALS AND METHODS: Between Jan and Dec 2009, fifteen patients (5 male, 10 female) received a diagnosis of lateral epicondylitis of the elbow and were evaluated in this study. Their average age was 43.5 years. All patients were initially given a variety of non-surgical treatments for more than 1year. All patients were considering surgery. These patients were given a single percutaneous injection of 3cc of platelet-rich plasma. To assess pain, we used a visual analogue scale (VAS) at rest and during work & the Patient-Rated Tennis Elbow Evaluation (PRTEE) score. We compared the score before treatment with scores 4 and 12 weeks after treatment. RESULTS: Average VAS scores at rest improved from 4.6 before treatment to 2.5 at week 4, and 1.8 at week 12. The average VAS score while working also improved from 7.8 before treatment to 6.2 at week 4, and 4.25 at week 12. The average PRTEE score improved from 60.13 before treatment to 46.12 at week 4 and 24.6 at week 12. CONCLUSION: Treatment using a single percutaneous injection of platelet-rich plasma in patients with refractory lateral epicondylitis appears to be an effective treatment modality. Platelet-rich plasma should be considered before surgical intervention.

Discal Cyst of Lumbar Spine: A Case Report

STUDY DESIGN: This is a case report. OBJECTIVE: We present here a patient who had a discal cyst of the lumbar spine along with neurological symptoms. SUMMARY OF THE LITERATURE REVIEW: Discal cysts are intraspinal cysts that communicate with an adjacent intervertebral disc, and these are rare lesions that can cause lumbar radiculopathy. Because they are very rare, their natural history and the details of the therapeutic guidelines for the treatment of these cysts are still unknown. MATERIAL AND METHODS: The patient complained of moderate lumbar pain and right lower extremity radiculopathy and he was administered conservative treatment for 5 months. But the radiculopathy became aggravated and he then underwent a hemilaminectomy, cyst decompression and discectomy. RESULTS: The radiculopathy disappeared and any signs of recurrence were not found on the follow up performed at 1 year. CONCLUSION: Discal cyst is rare, but it can be treated successfully.
