Renal angiomyolipoma (AML) is a benign tumor composed of fat cells, smooth muscle cells, and thick-wall blood vessels. Epithelioid angiomyolipoma (EAML) is a variant of AML and is composed of purely epithelioid cell with melanogenesis markers. Neither adipocytes nor abnormal blood vessels are noted. Pathologically, tumor cells have nuclear atypia and eosinophilic cytoplasm. EAML has a malignant...

Neoplasms are rare in pregnant women, however they are always a challenging diagnostic and curative problem. We present a case of a benign kidney tumor (angiomyolipoma) imitating nephroblastoma on magnetic resonance diagnosed in pregnancy. Cesarean section was performed in 29. gestotic week followed immediately by right radical nephrectomy.

INTRODUCTION Renal cell carcinomas account for 85% of all renal neoplasms. With the introduction of modern imaging modalities, there has been an increased diagnosis of renal tumors. Recent studies have shown that partial nephrectomy can be as safe as radical nephrectomy for smaller renal tumors. Renal cell carcinomas are usually unilateral, however, they can be bilateral in 2% to 4% of sporadic...

Renal-related disease is the most common cause of tuberous sclerosis complex (TSC)-related death in adults, and renal angiomyolipomas can lead to complications that include chronic kidney disease (CKD) and hemorrhage. International TSC guidelines recommend mammalian target of rapamycin (mTOR) inhibitors as first-line therapy for management of asymptomatic, growing angiomyolipomas >3 cm in diame...

Received August 2008 Accepted December 2008 INTRODUCTION Angiomyolipoma of the kidney has classically been considered as a tumor of the connective tissue composed of fat, vascular tissue, and smooth muscle. In most cases, it is a tumor with benign behavior that may appear sporadically or associated with tuberous sclerosis syndrome. Macroscopically, these tumors are greyish yellow in color, and ...

We experienced a rare case of hepatic angiomyolipoma (AML). A 66-year old Japanese female presented inhomogeneous echogenic lesion in the lateral segment of the liver on ultrasonography. Contrast computed tomography (CT) revealed early arterial enhancement within the lesion that stayed hyperdense in the equilibrium phase. Magnetic resonance imaging (MRI) demonstrated a non-homogeneous and parti...

Abstract Background Angiomyolipoma with epithelial cysts is a rare variant of an angiomyolipoma that typically occurs sporadically. Patients pre-existing kidney lesion or disease have significantly increased risk morbidity and mortality associated trauma. Abnormal diseased kidneys are frequently injured by low insignificant velocity impacts. The vulnerability these related to the type pathology...

UNLABELLED Synchronous occurrence of benign and malignant kidney tumours is very rare. We present the case of a 63-year-old female patient who underwent a bilateral partial nephrectomy after being diagnosed with bilateral kidney tumours by ultrasonography and a computed tomography scan. Histopathological analysis of the left kidney tumour mass revealed a chromophobe renal cell carcinoma. In the...

We have read with interest the article of Ding et al. (1), entitled “Comparison of biexponential and monoexponential model of diffusion-weighted imaging for distinguishing between common renal cell carcinoma and fat poor angiomyolipoma”, which was published in the Nov-Dec. 2016 issue of the journal. The study provides useful information. However, we would like to add a few comments. Angiomyolip...
