Fig. 14  (orig. Fig. 2–35). Mantle hair (F. Pinkus) shows a vellus hair follicle surrounded by a skirt of atrophic sebaceous epithelium. H&E. 2 180.
 

Message

 
A cloaked (mantle) hair is a "not too uncommon abnormality [that] has no pathologic significance in itself."
 
The mantle represents a skirt of atrophic sebaceous epithelium.
 

Critique

 
An atrophic mantle represents only half the story; the mantle at puberty is the anlage of a fully formed sebaceous gland.
