“…Most of the cells will belong to the proximal tubule followed in frequency by distal and collecting tubular cells. As mentioned before, brief descriptions of the normal kidney can be found in some cytology textbooks and reviews . Such descriptions coincide in the morphology of glomeruli but tubular cells are variable described and illustrated.…”

“…Such descriptions coincide in the morphology of glomeruli but tubular cells are variable described and illustrated. In some texts proximal tubular cells are reported as having well defined boundaries while others describe them as ill defined. Pigment is rarely mentioned and nonproximal tubular cells are variable reported.…”

“…It may be due in part to the scarcity of reports concerning cytomorphologic features of the normal kidney. Brief descriptions are found in some cytology textbooks and a few review articles, and such descriptions are not always similar . Textbooks usually illustrate glomeruli and tubular cells but no precise cytologic and immunophenotypic correlation study has been performed.…”

All cases showed: (a) glomeruli; (b) presence of at least 2 different epithelial cell populations that distribute separately, one representing the proximal tubule and the other more distal segments; and (c) existence of isolated, laminar basement fragments and slender, intact tubular structures. Proximal tubular cells were large with granular cytoplasm, indistinct cell borders, moderate anisonucleosis, and variable presence of pigment. Their immunophenotype was CD10+, AMACR+, PAX8-, and GATA3-. In all cases, cellular aggregates different of nonproximal tubular cells were present. They were smaller than proximal tubular cells with less cytoplasm, better-defined cell borders and uniform nuclei. Their immunophenotype was CD10-, AMACR-, PAX8+, and GATA3+ CONCLUSION: Aspirates from the normal kidney show characteristic features that permit a specific recognition. Different segments of the tubular system can be specifically recognized avoiding confusion with renal tumors. In difficult cases immunocytochemistry is a very helpful aid.

Ectopic adrenal cortical tissue has been reported in several locations, most often involving the retroperitoneal fat close to the adrenal gland. The reported cases presenting adjacent or proximal to the stomach are rare and mostly diagnosed on histology. To our knowledge, the cytologic features of ectopic adrenal cortical tissue diagnosed on fine needle aspiration are not well documented in the cytology literature. We describe the cytologic features of ectopic adrenal cortex which initially presented on imaging study as an enlarged gastrohepatic ligament “lymph node” on a patient with gastric signet ring cell carcinoma. The aspirates showed small clusters and cords of uniform cells with abundant vacuolated to densely compact cytoplasm, occasionally stripped nuclei, and delicate frayed cytoplasmic membranes dispersed in a bubbly, vacuolated background. Immunohistochemical stains performed on the corresponding cell block showed these cells were positive for SF‐1 and negative for PAX 8. The corresponding biopsy showed similar findings in addition to immunoreactivity to inhibin. Because the cytologic features of ectopic adrenal cortical tissue especially on unusual sites could easily mimic malignant neoplasms, familiarity with the cytologic features in conjunction with immunohistochemical stains are key in arriving at the correct diagnosis and avoiding misdiagnosis.
