“…This keratinous occlusion could result in a cystic dilatation of the proximal hair follicle and retention of vellus hairs in deeper levels of the follicle. 6,9,10,32 Kumakiri and colleagues proposed that EVHCs may be pilosebaceous hamartomas with the potential to differentiate toward vellus hair follicles. 33 In approximately 25% of cases, the cysts resolve spontaneously.…”

“…There is usually no race or sex predilection. 3,4 Pathogenesis is unknown, but theories postulate the possibility of a developmental abnormality that predisposes the hair follicle to infundibular occlusion. 5 Diagnosis is typically made based on clinical examination alone; however, a biopsy is used to rule out other conditions that can mimic EVHC.…”

“…Typical EVHCs are filled with laminated and amorphous keratinous material, and fragments of vellus hairs. The cyst wall consists of several layers of mature squamous cells 3,6 similar to those of infundibular or the isthmus portion of hair follicles 3,4,9,10 . Rarely, there are sebaceous glands within or near the cyst wall 11 …”
