Commento su Levitico 13:42

נגע לבן אדמדם A RISING OF THE SORE REDDISH-WHITE — variegated (the term לבנה אדמדמת does not signify white and red each separately, but mingled: reddish-white). Whence may we learn that the plague is unclean too if it has the other colours (not variegated, but plain white shades of white which are the distinguishing characteristics of the plagues)? Because it states here: נגע, a plague (it describes it as a ‘‘plague” and therefore all colors applicable to a “plague” apply to it also).

בקרחתו או בגבחתו, “on his bald head or bald forehead.” It is irrelevant if the area concerned normally produces a growth of hair or if it does not.
