WebReinke crystals appear to be hallmarks of normally differentiated, adult, Leydig or Leydig-like cells in humans, while some abnormal and nonhuman Leydig cells contain Reinke-like paracrystalline inclusions or crystalloids. WebAlthough testosterone-secreting adrenal adenomas are unusual, those that contain crystalloids of Reinke are extremely rare. Our case is the fourth reported case of virilizing adrenal adenomas with similar biochemical profiles that demonstrated these inclusions characteristic of Leydig cells.
