Giant compound hair follicles
Normally, these tufts are found around the rabbit's cheek and jaw area.

From Whiteley's article Giant Compound Hair Follicles in the Skin of the Rabbit: "As the hair shafts reach the surface the compound follicle is subdivided by fibrous septa into smaller groups which surround the large outer-coat hair. Each of these smaller groups of undercoat hairs penetrate the skin through a common follicle opening, whereas the outercoat hair has a separate opening."
