Multicystic dysplastic kidney (MCDK) is a relatively common developmental anomaly in infants and children and has a good prognosis. In contrast, a malignant rhabdoid tumor of the kidney (MRTK) is one of the most lethal neoplasms of early life. However, the presentation of such a lethal tumor combined with multicystic dysplasia has not been reported to date. In this report, we describe a case of...

Liposarcoma is one of the most common primary retroperitoneal neoplasms, and the perinephric region is a frequent location for them. Liposarcomas show a variety of radiographic features in terms of histological types and tumor sizes, so the specific diagnosis of liposarcoma is often difficult. We present a unique case of perinephric dedifferentiated liposarcoma mimicking cystic renal tumor. A 7...

Pleomorphic adenomas (benign mixed tumors) are the most common tumors of glandular origin in the head and neck and are one of the few benign neoplasms that can undergo malignant transformation.(1) Mixed tumors that are seemingly benign at the microscopic level but metastasize have been termed metastasizing mixed tumors (MZMTs). The entity of metastasizing benign mixed tumors has been reported s...

Ampullary neoplasms are one of the causes of obstructive jaundice. Endoscopic retrograde cholangiopancreatography (ERCP) is useful procedure for diagnosing and tissue sampling of ampullary neoplasms. Ampullectomy by resecting entire ampulla provides whole lesion for pathologic evaluation and also is appropriate for real pathologic staging for further management decision but ampullectomy conside...

Hexachlorobutadiene (HCBD), while not produced commercially in the United States, may be encountered as an unwanted by-product of certain processes associated with the chlorination of hydrocarbons. Studies were conducted to assess the potential long-term toxicity of HCBD. In a reproduction study conducted in rats, dose levels of 20 or 2.0 mg/kg-day of HCBD induced slight maternal toxicity (prim...

INTRODUCTION Renal cell carcinomas (RCC) are collectively the third most common type of genitourinary neoplasms, surpassed only by prostate and bladder cancer. Cure rates for renal cell carcinoma are related to tumor grade and stage; therefore, diagnostic methods for early detection and new therapeutic modalities are of paramount importance. Epigenetics can be defined as inherited modifications...

renal actinomycosis is a rare infection, and actinomycosis mostly acts as a normal flora in mouth, colon and vagina. we present a case of 56 years old man, who referred to our center for renal transplantation with kidney stone and diagnosed  with renal actinomycosis.  this case has risen possibility of rare infection that can be considered in the setting of renal transplantation.
