Received July 2006 Accepted October 2006 INTRODUCTION Horseshoe kidney, first recognized at autopsy by DeCarpi in 1521, is a renal fusion anomaly found in about 0.25% of the population.(1) Malignancies are associated with this anomaly and adenocarcinoma comprises about 50% of tumors arising in the horseshoe kidney.(1) We report a case of renal cell carcinoma in a 66-yearold man and depict our e...

We prove John Hubbard’s conjecture on the topological complexity of the hyperbolic horseshoe locus of the complex Hénon map. In fact, we show that there exist several non-trivial loops in the locus which generate infinitely many mutually different monodromies. Furthermore, we prove that the dynamics of the real Hénon map is completely determined by the monodromy of the complex Hénon map, provid...

Horseshoe kidney is a rare congenital anomaly that may cause various technical problems during conventional repairs of abdominal aortic aneurysms. We report the case of a 68-year-old woman with a horseshoe kidney, symptomatic abdominal aortic aneurysm and mild renal failure. The patient underwent endovascular repair using a bifurcated endoprosthesis. The postoperative was uneventful. We describ...

Owing to the limited donor pool at transplant centers, grafts may be taken from marginal donors with congenital abnormalities, one of the most common of which is a fusion abnormality. Horseshoe kidneys may be transplanted to a single recipient en bloc or to 2 recipients after division. In our clinic, 3 grafts (1 obtained from a living donor and 2 from a deceased donor) were successfully transpl...

because of an unknown factor, the frequency of complicated pregnancy with placenta previa has been raised during past decade. this study was designed to deepen our understanding of risk factors and outcomes of placenta previa in our country. this study investigated 694 cases of placenta previa comparing with 600 healthy pregnant women with not overlie placenta in two referral and tertiary obste...

to investigate the effects of certain factors on the rate of retained placenta, 2844 calving records from 1288 holstein cows in a herd were used. these cows calved during year period of 2001 to 2007. a generalized statistical linear model was applied to analyze the data. logistic regression model was applied as the statistical model. in the model, fixed effects of year, season (warm or cold) an...

Primary carcinoid tumor of the kidney is a very rare entity (< 1%). About 90 cases have been reported in the literature. Carcinoid tumors appear over-represented in horseshoe kidneys compared with normal renal anatomy. Herein, we reported a 33-year-old male with primary renal carcinoid tumor arising from a horseshoe kidney. The tumor showed nests and trabeculea of uniformly polygonal cells sepa...

A preliminary report in 1965 described a conservative surgical procedure for the management of acute and chronic horseshoe anal fistulas. The operation has been used exclusively at the Ochsner Clinic for this problem since 1963. Forty-one patients were treated from 1963 to 1973. The paper reviews the pathology of acute and chronic horseshoe anal fistulas and describes the surgical procedure for...

background & aim: cervical ectopic pregnancy is a rare variant of ectopic pregnancy, and placenta percreta is a complex and dangerous condition; patients with these conditions are difficult to manage. in this study, we present a rare case of placenta percreta in cervical pregnancy. case report: a 32 -year-old woman with 19 weeks of gestation and gross hematuria was admitted to qaem hospital in ...

pedunculated chorangioma is extremely rare type of chorangioma. to the best of our knowledge, no case has been reported in indian literature. we report one such rare case in a twenty two year old primi gravida who delivered a full term live female baby by lower section caesarian section (lscs). gross examination revealed a nodular mass attached to the placenta by a pedicle. histopathological ex...
