uncommon soft tissue tumor initially reported in the pleura but recently described in other sites in the body (1). Previously these tumors were mostly classified as localized mesotheliomas of the pleura, either benign or malignant (2). The morphological distinction between benign and malignant LFT is often difficult. An immunohistochemical study was performed in pleural and extrapleural sites (...

Purpose. In the clinical work-up of a retroperitoneal mass, the diagnosis of soft tissue sarcoma is often not considered. Incidence rates of various malignant and benign retroperitoneal tumours were studied to determine the incidence of soft tissue sarcoma in comparison with other neoplasms in the retroperitoneal space.Method. Nation-wide data on retroperitoneal tumours, collected prospectively...

Granular cell tumor (GCT) is a Schwann cell related benign neoplasm of soft tissue. GCT is an uncommon entity that occurs in a wide variety of body sites, but it is generally presented in the skin, oral cavity, superficial soft tissue, and respiratory and digestive tracts. Most of the GCTs are benign but clinically and radiologically these may mimic malignancy. Histopathological diagnosis is go...

BACKGROUND Liposarcoma is a malignant tumour that arises in fat cells in deep soft tissue. This study was conducted to access the spectrum of liposarcomas METHODS This descriptive study was conducted at Armed Forces Institute of Pathology (AFIP), Rawalpindi from 1st January 2008 to 31st December, 2012 and included all the cases diagnosed as liposarcomas. Records of the malignant tumors of sof...

Reprint requests to: Dr. Michael Mu Huo Teng Department of Radiology, Taipei Veterans General Hospital. No. 201, Shih Pai Road, Taipei 112, Taiwan, R.O.C. Synovial sarcoma is a rare and aggressive soft tissue tumor with extensive metastatic potential. It accounts between 8 and 10% of all soft tissue malignancies. Involvement of the head and neck region is relatively rare. We report a case of sy...

Few cases of equine mast cell tumour have been reported in the literature. Most describe solitary nodular lesions of the skin and subcutaneous tissue that occasionally involve the underlying musculature (Altera and Clark 1970; Doran and Collins 1986; Nyrop et al. 1986; McEntee 1991). Lesions are generally confined to soft tissues and appear to be hyperplastic rather than neoplastic. One case in...

BACKGROUND Low-grade fibromyxoid sarcoma (LGFMS) is a distinctive slow growing soft tissue neoplasm, mostly affecting young individuals with no gender difference. It usually arises in deep soft tissue of the lower limbs and trunk, but few cases of LGFMS located in pelvis have been reported. CASE PRESENTATION We describe the magnetic resonance imaging(MRI) features of LGFMS located in the ante...

The peripheral primitive neuroectodermal tumor (pPNET) is a rare and highly malignant soft tissue neoplasm in children and young adults. Fewer than 10 reported cases of pPNET of maxilla are available in the English literature. A 28-year-old woman was presented with the pPNET of the maxilla and metastasis. Two years after diagnosis, she experienced diplopia, and then magnetic resonance imaging w...

Primary schwannoma of the large intestine is an extremely rare neoplasm. Here, we report two cases of colonic schwannoma confirmed pathologically after laparoscopic resection. A 52-year-old female and a 59-year-old female were referred by their general practitioners to our coloproctologic clinic for further evaluation and management of colonic submucosal masses. Colonoscopies performed in our i...
