Abstract:
Angiomyolipoma with epithelial cysts (AMLEC) is a very uncommon renal tumor. AMLEC has a characteristic histological appearance and immunohistochemical staining pattern, knowledge of which should preclude misdiagnosis by pathologists. We present a rare case of an AMLEC which was suspected to be a cystic renal cell carcinoma radiologically. We describe the characteristic immunological staining pattern and ultrastructural features of this lesion and discuss the potential differential diagnoses.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
External Anatomy of the Kidney
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...
Internal Anatomy of the Kidney
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.
Renal Cortex
The outermost region of the kidney is the...
