gastrointestinal stromal tumors are mesenchymal neoplasms of the gastrointesti- nal tract that originate from all areas of the gastrointestinal tract. metastases to the liver, peritoneum, bones, lungs and soft tissues have been reported. we present the case of a 47- year-old woman with rectal gastrointestinal stromal tumor that underwent wide local excision. she was treated with imatinib for a ...

A 44-year-old woman underwent surgery for lung cancer. Although preoperative computed tomography did not reveal a tiny nodule, pathological examination of the background lung showed that type II pneumocyte-like tumor cells grew papillary in an area of approximately 2.3 × 1.2 mm. This lesion exhibited hemorrhage, hemosiderosis, calcification, and varying degrees of fibrosis, leading to the diagn...

sclerosing hemangioma of the lung is extremely rare.  herein, a case of sclerosing hemangioma of the lung in a 44-year-old woman is reported.  on admission, the patient complained of pain in the left lower neck and upper chest.  chest x-ray revealed a mass in lingular lobe of the left lung.  the patient underwent surgery and a mass was removed through left posterolateral thoracotomy.  pathologi...

INTRODUCTION Gastrointestinal stromal tumor is the most common malignant mesenchymal tumor of the gastrointestinal tract. The most common sites of metastasis are the liver and the peritoneum, but gastrointestinal stromal tumors rarely metastasize to the skeletal muscles. Only three cases of gastrointestinal stromal tumor metastasizing to skeletal muscle have been reported in the English literat...

This report describes the histological and immunohistochemical features of a small intestinal tumor that resembled a human gastrointestinal stromal tumor (GISTs) in a seven-year-old male cross-breed dog. This was unique because of the expression of desmin by the tumor. Grossly, the white-gray tumor measured 8.0 × 4.0 × 6.5 cm and was 760 gram in weight. It was cystic and enveloped the jejunum. ...

OBJECTIVE Phyllodes tumor is a rare fibroepithelial neoplasia of the breast. Tumors are classified according to the histological criteria as benign, borderline, malignant groups. Criteria used to discriminate benign/malignant cases are stromal cytological atypia, stromal hypercellularity, mitotic rate, stromal overgrowth, and tumor margins. We designed this study retrospectively to see the vali...

Introduction: Steroid cell tumors (SCTs) constitute less than 0.1% of all ovarian tumors. They are divided into 3 categories according to cell of origin: Stromal Luteoma arising from stromal cells of the ovary, Leydig cell tumor arising from Leydig cells, and SCT not otherwise specified (NOS) when the origin of the tumor is not defined. Case Presentation:...
