BACKGROUND Solitary fibrous tumors (SFT) represent a rare entity of soft tissue tumors. Previously considered being of serosal origin and solely limited to the pleural cavity the tumor has been described in other locations, most particularly the head and neck. Extrathoracic SFT in the soft tissues of the trunk and the extremities are very rare. Nine cases(More)
BACKGROUND Alveolar sarcoma of the soft parts (ASPS) represents a very rare entity of soft tissue sarcoma with special features such as young peak age incidence and frequent metastasis to the brain. The aim of this study was a clinicopathological analysis with special reference to treatment and outcome. METHODS From the database of the BG-University(More)
BACKGROUND Elastofibromas are benign soft tissue tumours mostly of the infrascapular region between the thoracic wall, the serratus anterior and the latissimus dorsi muscle with a prevalence of up to 24% in the elderly. The pathogenesis of the lesion is still unclear, but repetitive microtrauma by friction between the scapula and the thoracic wall may cause(More)
BACKGROUND Proximal major limb amputations due to malignant tumors have become rare but are still a valuable treatment option in palliation and in some cases can even cure. The aim of this retrospective study was to analyse outcome in those patients, including the postoperative course, survival, pain, quality of life, and prosthesis usage. METHODS Data of(More)
BACKGROUND The aim of this study was to identify prognostic indicators of survival in patients with locally recurrent soft tissue sarcoma (STS) through a long-term follow-up. METHODS We retrospectively assessed the relationship between post-recurrence survival (PRS) and potential prognostic factors in 135 patients who had experienced local recurrence,(More)
The aim of this study was to examine the clinical course of patients with the rare finding of regional lymph node metastasis (RLNM) from soft tissue sarcoma. Data from 28 out of 1,597 consecutive soft tissue sarcoma patients with RLNM were from the patients’ charts and interviewing patients and general practitioners. Survival, including possible influencing(More)
Gorham-Stout disease is a rare idiopathic syndrome with distinctive clinical, pathologic and radiologic features. It is a variant form of osseus angiomatosis associated with massive osteolysis of bone. Usually appearing after trauma, the disease is described to occur at any age. Especially in case of thoracic involvement (chylothorax), lethal outcomes are(More)
Undifferentiated pleomorphic sarcoma/NOS (not otherwise specified; former pleomorphic and storiform MFH) of the extremities is a common malignant soft tissue tumor in adults. The objective of this study is to determine prognostic factors for the outcome after surgical treatment with respect to the recent developments in classification. From 1996 to 2004,(More)
Growth factors are important substances in the central control of wound healing during the exudative phase. Although these peptides have been applied frequently to chronic wounds in clinical studies, little is known about the naturally occurring levels at the wound site in correlation to healing in superficial wounds. We have therefore investigated the(More)
Seit 2005 wird der freie anterolaterale Oberschenkellappen (ALT) zur Defektdeckung im Bereich der oberen und unteren Extremität in unserer Klinik eingesetzt. Die Indikationen für den Lappentransfer sind vielfältig und umfassen u. a. posttraumatische Defekte, Defekte infolge von akuten und chronischen Infektionen und Weichteildefekte nach onkologischen(More)
