hemangioma of the ovary is reported in a 66 years old woman. vascular tumors of the female genital tract are rare, especially those of the ovaiy. most cases are discovered incidentally. the case presented here was missed clinically.

primitive  neuroectodermal  tumor  (pnet)  of  kidney  is  an  extremely  rare  renal  neoplasm  with only about fifty reported cases in literature.  presumably,of neural crest origin, these tumors behave  aggressively  and  carry  a  poor prognosis.  we  report  a  case  of  22-year  old  female  patient complaining of left loin pain with recurrent hematuria for last 3 months. on clinical exam...

introduction hemangiomas are the most common benign tumor of infancy that can occur anywhere in the body. intramuscular hemangiomas (imh) are accounting for approximately 1% of all cases and the muscles of extremities are the most common sites. because of scarcity and variable clinical features of these tumors, we decided to report a case of imh in the upper lip mucosa. case report the patient ...

background: gbm is the most common and malignant astrocity tumor and it is persistent to common treatment so, these patients have a very low survival. several researchers around the world, including iran, have been investigated gbm-cell line in vitro. however in vivo studies have not been fulfilled. methods : as standard cell line (u-87mg) derived from human gbm and total gbm tumor derived from...

giant cell tumors (gct) are benign tumors with potential for aggressive behavior and capacity to metastasize. although rarely lethal, benign bone tumors may be associated with a substantial disturbance of the local bony architecture that can be particularly troublesome in peri-articular locations. its histogenesis remains unclear. it is characterized by a proliferation of mononuclear stromal ce...

introduction: inflammatory myofibroblastic pseudotumors are initially described in the lung and various extrapulmonary sites such as the orbits, palatine tonsils, ears, gingiva, pterygomaxillary space, and periodontal tissues. these tumors rarely involve the larynx and predilection to the glottis occurs in an indolent manner.   case report this case describes a laryngeal myofibroblastic tumor i...

Diaphanoscopy/transillumination, the method of shining a bright light through tissues, was devised in the mid-19(th) century and developed after the invention of the light bulb by T.A. Edison. Benjamin Milliot was the first to examine the stomach by means of an incandescent platinum wire. The experiments conducted by Max Einhorn using a device consisting of a Nelaton catheter with an inserted l...

In this note we consider to what extent the classical theorems of Plessner and Kuttner comparing the set of convergence of a trigonometric series with that of the conjugate trigonometric series can be generalized to higher dimensions. We show that if a function belongs to LP, p > 1, of the 2-torus, then the convergence (unrestricted rectangular convergence) of the Fourier series on a set implie...

By historical standards, the U.S. economy has experienced a period of remarkable stability since the mid-1980s. One explanation attributes the diminished variability of economic activity to information-technology led improvements in inventory management. Our results, however, indicate that the changes in inventory dynamics since the mid-1980s played a reinforcing–rather than a leading–role in t...

We examine the extent to which fluctuations in the money stock anticipate (or Granger cause) fluctuations in real output using a variety of rolling window and increasing window estimation techniques. Various models are considered using simple sum as well as Divisia measures of M1 and M2, income, prices, and both the Tbill rate and the commercial paper rate. Findings indicate that the relation b...
