A 73-year-old man developed refractory multiple hemorrhagic gastric ulcers. Emergent gastrectomy was performed, and the diagnosis of polyarteritis nodosa was made by histologic evaluation of the resected stomach. Although gastric ulceration is a relatively rare complication of polyarteritis nodosa, it should be considered in the differential diagnosis of refractory hemorrhagic gastric ulcers. E...

Background: Ovarian cancer is the most common cause of cancer death worldwide. Incidence of ovarian cancer is more common in postmenopausal women. Premenopausal onset is rare and the present study described two cases of ovarian clear cell tumors in young women. Case Presentation: The patients presented with pelvic mass which was confirmed by sonography and laparotomy and final diagnosis was ...

Fungal infections of the gastrointestinal tract are not common in children, especially in immunocompetent ones. In this case report we describe a child who was presented with abdominal pain and mass, bloody diarrhea and fever. He was treated for amebiasis, but due to treatment failure and deterioration of his condition, he underwent a laparatomy. Histologic examination of the excised bowel in ...

Patients with disseminated follicular non-Hodgkin's lymphoma (NHL) are only occasionally cured with standard chemotherapy regimens. Although most of these tumors are initially responsive to chemotherapy, in 40% to 70% of patients the lymphoma will eventually transform to an NHL of higher grade malignancy and a poorer prognosis. We treated 18 patients having an original diagnosis of follicular N...

We studied the role of fine-needle aspiration (FNA) in the evaluation of lymphadenopathy associated with cutaneous T-cell lymphoma (CTCL) in 11 patients with lymphadenopathy and compared findings with corresponding histologic material. Molecular genetic analysis for T-cell clonality by polymerase chain reaction (PCR) was performed on all aspirates. Immunophenotyping was successful in 4 of 7 cas...

PURPOSE To clarify the prognostic value of molecular diagnosis of SLN metastases in cervical cancer using SCCA. EXPERIMENTAL DESIGN All SLNs and primary tumors, part of non-SLNs, were harvested from 36 patients with cervical cancer. Expression levels of SCCA, cytokeratin 19 (CK19), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) mRNA in 178 samples (29 primary tumors, 5 histologic positi...

malignant fibrous histiocytoma (mfh) is the most common soft-tissue sarcoma which predominantly surfaces in the retro-peritoneum and extremity. mfh of lung is a very rare condition. the diagnosis is essentially through histologic examination. however, the invasion of the chest wall or other organs might help establish the malignant nature.we report a case of a 77-year-old man who had been prese...
