Fig. 6 A (orig. Fig. 2), Two vellus hair follicles of different size, both with a downward sloping hanging collar. B (orig. Figs. 4 and 5), Vellus hair follicles in cross-section in which the hanging collar appears as a ring. C (orig. Figs. 12 and 13), Vellus hair follicles in cross-section. The hanging collars show sebaceous changes.
The anlage of sebaceous glands surrounds the follicle like a collar and merges with the outer sheath.
The appearance of the collar varies according to how a specimen is sectioned. In longitudinal section, mantle epithelium assumes the shape of a cone. In cross section, it has the appearance of a ring. If cut obliquely, it may have the shape of a sickle.
Three types of collars of epithelium were noted, namely, the most common ring-like, the downward sloping, and the occasional upward oriented type that usually occurs in combination with the downward sloping one.
Zimmermann's collar is Pinkus's mantle.
Zimmermann, through drawings, illustrated beautifully many of the morphologic expressions of collars (mantles) both in terms of patterns and cytologic features.
Zimmermann noted correctly that the appearance of collars is dependent, in part, on how a specimen is sectioned.
