“Among the other interesting structures found in dermoid cysts must be mentioned nails (finger nails), of which very fine specimens are to be found in the museum of the Anatomical Institute in Vienna. Olshausen says: ‘It should not be considered strange if nails belonging to the skin are frequently found in dermoid cysts, just as, in the sheep, wool has been found in dermoids, and in cows, hair, and in birds, feathers in dermoid cysts. The collection in the Gynecological Clinic in Halle contains a specimen of a dermoid cyst of a goose containing very numerous feathers.’”
