Adrenal rest in testis diagnosed by fine‐needle aspiration cytology

In this article, we have described an extremely uncommon entity of adrenal rest in testis in fine‐needle aspiration cytology in a 7‐year‐old male child with symptoms of precocious puberty. The patient had a raised serum testosterone level along with a well‐defined solitary mass in the testis. Fine‐needle aspiration cytology smears show a dispersed population of large cells with abundant finely granular cytoplasm, eccentric nuclei, coarse nuclear chromatin, and multiple prominent nucleoli. Considering the clinical, radiological, biochemical, and also cytological features, a diagnosis of adrenal cell rest was made. Diagn. Cytopathol. 2011. © 2010 Wiley‐Liss, Inc.
