[Atypical cysts in the area of the macula sacculi of the guinea pig (author's transl)].

In some guinea pigs cysts in the area of the macula sacculi and along the saccular nerves can be observed. They are built up by a surrounding layer of connective tissue, by a basilar membrane, cylindric epithelia, and by a central space with gelatinous contents. The cylindric epithelia are very similar to the supporting cells in the marginal area of the macula sacculi. A temporary secretory activity of these cylindric epithelia of the cysts is discussed.
