Concurrent hepatic and ruptured renal angiomyolipoma in tuberous sclerosis complex.

چکیده
Angiomyolipoma of the liver or kidney is one of the clinical manifestations of tuberous sclerosis complex. However, concurrence of angiomyolipoma in both liver and kidney associated with tuberous sclerosis complex is a rare entity. Renal angiomyolipomas with large aneurysms confer a higher probability of rupture as compared to small aneurysms. Herein, we document a case of tuberous sclerosis coexisting with hepatic and renal angiomyolipoma in a 37 year-old woman who presented with an acute abdomen due to ruptured tumor. Computed tomography of the abdomen revealed multiple tumors over the bilateral kidneys and liver. A right nephrectomy was performed. During surgery, a liver biopsy was performed from which a preliminary diagnosis of necrosis was established. However, immunoreactivity staining using monoclonal antibody HMB-45 (Human Melanoma, Black) led to the final diagnosis of angiomyolipoma. We emphasized that pathologists and clinicians should be aware that cases of tuberous sclerosis complex may be associated with renal and hepatic angiomyolipoma. To avoid an inappropriate diagnosis, before diagnosing liver necrosis, immunohistochemical staining for HMB-45 is recommended.

We present a patient of tuberous sclerosis complex with bilateral renal angiomyolipoma and hepatic angiomyolipoma with spontaneous retroperitoneal hemorrhage from right angiomyolipoma (Wunderlich's syndrome). Nephron preserving approach was tried but the right kidney could not be salvaged. Hepatic angiomyolipoma was managed conservatively. Wunderlich's syndrome has been found in around 10% of c...

The tuberous sclerosis complex (TSC, OMIM 191100) is a rare autosomal dominant syndrome of high penetrance characterized by hamartoma in multiple organs, namely brain, kidneys, heart, skin, eyes and lungs [1]. The classic clinical triad includes seizures, mental retardation and cutaneous adenoma sebacea. Besides common vascular abnormalities observed in angiomyolipoma, TSC can be associated wit...
