There is an ongoing debate on the question of which exchange rate regime is better suited to guarantee stability: fixed or flexible rates? The macroeconomic crisis in Argentina has again stimulated the discussion. In this paper, we argue that it is misleading to solely concentrate on exchange rate policy to assess the preconditions for stability in an international surrounding. Instead, we show...

The bening tumors of paratesticular tissues are uncommon and their frequency rating is as follows:adenomatoid tumor,leiomyoma and papilliferous cystadenoma.this paper reports two new cases of epididymal adenomatoid tumor in 43 and 25 years old males presented with testicular pain and a mass in their testes.diagnosis was achieved through physical examination and sonography with confirmed patholo...

Neurofibroma is a tumor composed of a complex proliferation of neuromesenchymal tissue (Schwann cells, perineural cells, fibroblast, and mast cells). We report a 45-year-old female who had a slow growing, large, soft, pedunculated mass on her left lateral neck. A skin biopsy confirmed the diagnosis of neurofibroma.

BACKGROUND AND AIM: Solitary fibrous tumor (SFT) is a quite uncommon tumor that commonly occurs in the pleura but occasionally involves an oral cavity. We are reporting this rare case in the oral cavity. The diagnosis depends on microscopic and immunohistochemical features. Patients with these tumors can be carefully treated with local excision, but tumors with...

objective(s): this study aimed to evaluate the role of pretreatment suvmax and volumetric fdg positron emission tomography (pet) parameters in the differentiation between benign and malignant mediastinal tumors. in addition, we investigated whether pretreatment suvmax and volumetric fdg-pet parameters could distinguish thymomas from thymic carcinomas, and low-risk from high-risk thymomas.method...

a malignant peripheral nerve sheath tumor (mpnst) is very rare, representing 3 - 10% of all soft tissue sarcomas. approximately half of all such tumors are diagnosed in patients with neurofibromatosis type 1 (nf1). the extremities are involved most commonly, and the patient’s age is usually 20 - 50 years. herein, we present a case of an mpnst that developed sporadically in an unusual location a...

ependymomas are glial tumors originate from ependymal cells lining the ventricles and the central canal of the spinal cord. two thirds of ependymomas arise in the infratentorial or intraventriclesandone-third aredetected in supratentorial area. however supratentorial “cortical” ependymomas are veryuncommon. ependymomas are usually infratentorial, intraventricular tumor, including 2–9% of all ce...

rhabdomyomata are probably the most common tumors that occur very rarely during infancy. in this paper, we report the case of a 49-day-old infant who was diagnosed by echocardiography examination with left ventricle outflow tract (lvot) obstruction caused by rhabdomyoma. the infant underwent surgical approach, and her mass was shaved. finally, she was discharged from hospital in good general co...

ovarian borderline serous tumors are uncommon. combination of borderline serous adenofibromatous tumor and prominent micro papillary architecture is not previously reported. we report a case of borderline papillary serous adenofibromatous tumor (also called serous adenocarcinofibroma) with extensive micropapillary pattern in a 27 year-old married woman. she was infertile and presented with diff...
