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...

Different preparations obtained from cultures of Serratia marcescens and Strepto coccus pyogenes were tested in seven spontaneous, induced, and transplanted tumors of mice, and Rous sarcoma in chicks. The toxins were found to be effective against Krebs-2 carcinoma causing regression of well established tumors. They were found to be ineffective against Sarcoma 180, Gardner's Lymphosarcoma 6C3HED...

Periductal stromal sarcoma (PSS) is a an extremely rare low-grade malignant neoplasm arising from breast periductal stroma. It usually occurs in peri and post-menopausal women. Herein, we report case of 14 year girl, known recurrent Rhabdomyosarcoma (RMS) presenting with breast. To the best our knowledge, this first its kind to be reported literature. A 14year Recurrent Pleomorphic retroperiton...

 Material Methods: A total 96 ( 37 female, 59 male ) presented our department period 17 years (2003-2020) diagnosis radius were analyzed. The assessed according age, ge...

Intracardiac malignancies are most commonly metastatic cardiac tumors, and they are 20–40 times more common than the primary cardiac malignancies. Synovial sarcoma, an uncommon mesenchymal tumor itself, commonly spreads to the lung, but very rarely to the heart in the literature. Superior vena cava syndrome (SVCS) occurs because of the obstruction of blood flow in superior vena cava, mostly bec...

BACKGROUND Cardiac tumors are rare, mostly benign with high embolic potential. OBJECTIVES To correlate the histological type of cardiac masses with their embolic potential, implantation site and long term follow up in patients undergoing surgery. METHODS Between January 1986 and December 2011, we retrospectively analyzed 185 consecutive patients who underwent excision of intracardiac mass (...

Tumors of peripheral nerve are largely neuroectodermal in nature and derived from 2 elements of nerve, Schwann or perineurial cells. In contrast, mesenchymal tumors affecting peripheral nerve are rare and are derived mainly from epineurial connective tissue. The spectrum of the latter is broad and includes lipoma, vascular neoplasms, hematopoietic tumors, and even meningioma. Of malignant perip...

Background. The origin of Ewing's sarcoma in a periosteal location is rare and not clearly documented. Other malignant bone tumors appear to have a somewhat better prognosis when confined between periosteum and bone. Is it the same for periosteal Ewing's sarcoma?Methods. We describe two new cases and comprehensively review the literature consisting of 18 documented cases since the condition was...
