Rhabdomyosarcoma of the breast is an extremely rare condition. Billroth (1860) described such a tumour in the left breast of a young girl aged 16 years. It was a large unencapsulated neoplasm and was composed of elongated muscle cells with distinct cross-striations and large granular myoblasts. The tumour recurred after local excision. The subsequent history of the patient was not recorded. Sai...

INTRODUCTION Solitary fibrous tumors of the central nervous system usually present as dura-based masses and clinically resemble meningiomas. There are very few reported cases of intra-ventricular solitary fibrous tumors, particularly in the fourth ventricle. CASE PRESENTATION Our patient was a 52-year-old African-American man, who presented to our facility with a two-month history of progress...

The suppression of the regenerative chatter phenomenon in turning process via the variation of the frequency and amplitude of the spindle motor excitation is carried out in this research. A programmable inverter is employed for variable periodic excitation of the spindle motor. A set of turning experiments is designed and performed on a number of conical work pieces both in constant spindle spe...

BACKGROUND Oncologic patients who are extreme responders to molecularly targeted therapy provide an important opportunity to better understand the biologic basis of response and, in turn, inform clinical decision making. Malignant neoplasms with an uncertain histologic and immunohistochemical characterization present challenges both on initial diagnostic workups and then later in management, as...

tric pain since 2 weeks. Esophagogastroduodenoscopy (EGD) revealed a 3-cm submucosal mass in the posterior wall of the gastric body. Abdominal ultrasound showed a multilocular cystic lesion (10 × 6 × 9 cm) in the pancreatic tail. Endoscopic ultrasound (EUS) confirmed a multicystic lesion arising from the pancreas (●" Fig. 1). The cysts were macrocystic in nature, ranging from 1 cm to 2 cm in si...

spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. spindle cell neoplasms can affect the oral cavity. in the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. this article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology.  ...

Ovarian carcinosarcoma composed of high-grade carcinoma and sarcoma is an extremely rare neoplasm typically occurs in postmenopausal women aged over 60 years. A 73-year-old female, gravida three para three, presented to our hospital with right lower abdominal pain. Right pelvic solid tumor ascites was detected on ultrasound examination. She underwent hysterectomy, bilateral salpingo-oophorectom...

A 45-year-old man was referred to our hospital with a gastric nodule. Gastroscopy revealed a flat, pale-colored lesion, approximately 15mm in diameter, in the gastric body. The lesion showed some nodularity but seemed to be covered with a slightly inflamedmucosa (●" Fig.1). Endoscopic ultrasound (EUS) showed a thickened mucosal layer, as well as scattered, small hypoechoic areas in the submucos...

Abstract Background Primary thyroid leiomysosarcoma is a rare and aggressive disease which represents 0.014% of primary cancers. It confers diagnostic conundrum, due to difficulty make preoperative diagnosis leiomyosarcoma differentiate it from anaplastic carcinoma. Case presentation We herein report case leiomyosarcoma. A 48-year-old male presented with history anterior neck swelling for the p...
