research A HISTOCHEMICAL TEST FOR CITRULLINE ADAPTATION OF THE CARBAMIDO DIACETYL REACTION TO HISTOLOGIC SECTIONS WITH POSITIVE RESULTS IN PILOMATRIXOMAS (CALCIFYING EPITHELIOMAS)
This study reports that citrulline, uniquely found in the inner root sheath of hair follicles, can be specifically detected with the carbamido diacetyl reaction, resulting in a bright orange color.
