Granular cell tumors (GCTs) are rare soft tissue neoplasms and occur in different parts of the body. We report a case of granular cell tumour of common bile duct (CBD) in a 39 years old lady, presenting with obstructive jaundice. Magnetic resonance cholangiopancreatography (MRCP) showed it as a benign looking mass in CBD. Complete surgical excision of the tumour was done. Histopathology was con...

Angiosarcoma is a rare vascular soft tissue tumor of endothelial origin most commonly seen in the elderly as a primary cutaneous head and neck malignancy. Furthermore, a peritoneal angiosarcoma is an exceedingly rare entity. This is the second case of primary peritoneal angiosarcoma reported in literature that is not associated with prior radiotherapy. Herein, we describe a case of primary peri...

A gastrointestinal stromal tumor (GIST) is a soft tissue sarcoma that can occur anywhere along the gastrointestinal (GI) tract and is the most common noncarcinomatous malignancy of the GI tract. This article will review the pathology of GISTs, the molecular pathology related to c-kit, and disease management and will discuss a new drug approved in the management of GISTs, sunitinib malate. In ad...

Malignant melanocytic melanoma is a rare sinonasal malignancy. We present a case report of an elderly lady who presented with epistaxis and intranasal polyps. Computed tomography revealed soft tissue mass in the oropharynx, nasopharynx, left ethmoid and entire maxillary sinus. The mass was removed via endoscopic medial maxillectomy. Histopathology examination revealed sinonasal melanocytic mali...

Introduction: Soft tissue has a prominent role in diagnosis and treatment plan in orthodontics. Facial proportions are measurable on lateral cephalograms. The purpose of this study was to compare the means of the normal soft tissue proportions of babol people with the norms of Caucasians. Materials & Methods: In this cross-sectional study, 100 cases with normal occlusion and proportional facia...

Using imunohistochemical technique, localisation and intensity of COX2 expression were estimated in canine soft tissue fibrosarcomas. The obtained results were related to tumour grade of malignancy. The material was sampled in the course of surgery from 23 dogs of various breed, 5 to 18 years of age. The presence of COX2 was demonstrated in cell cytoplasm in over 43% tumours. Augmented expressi...

primitive neuroectodermal tumor (penets) is an uncommon malignancy of bone and soft tissue witch rarely occurs in the kidney. in more than 90% of the cases, the tumor cells relieves a balanced translocation (11; 22) (q24; q12). immunohistochemical staining may be required for diagnosis of penet. the cells of tumor express cd99, vimentin, nse, fl1 but do not express ck, lca, myogenin, and wt1. w...

malignant peripheral nerve sheath tumor (mpnst) is a rare malignant tumor that develops either from a preexisting neurofibroma or de novo. the cell of origin is believed to be the schwann cell and possibly other nerve sheath cells. in this report, we describe a rare case of mpnst that arise from the socket of second left maxillary molar that has been already extracted in a young man. he was ref...

INTRODUCTION Lipoma is a benign tumor of adipose tissue, the most common tumor of the human body soft tissues. As such, it can be found almost anywhere in the human body including the gastrointestinal system (incidence below 0.5%), but rarely in the sigmoid colon. CASE REPORT This is a case report on symptomatic polyp of the sigmoid colon, which after one year, at control colonoscopy, caused ...
