[Friedrich Berthold Reinke (1862-1919) : Rostock anatomist and describer of Reinke's crystals in the testis and Reinke's space in the larynx].

The 95th anniversary of the anatomist Friedrich Berthold Reinke's death is 19 May 2014. This an excellent moment to remember his anatomical research. Two structures which he discovered and first described continue to be associated with his name: Reinke crystals of testicular Leydig cells and Reinke's space in the larynx. Reinke's crystals are crystalline protein aggregates within interstitial Leydig cells which are probably associated with testosterone production. They are pathognomonic for Leydig cell tumours.
