Follicular unit extraction (FUE; also follicular unit excision or follicular transfer, FT) Performed under local anaesthetic, FUE procedure involves the harvesting of individual hair follicles from the donor site at the back of the head using a tiny 0.8 - 1mm punch which creates an incision around the top of the follicle and extracts them directly from the scalp.
The disadvantage of the 1 mm punch is that the tissue obtained is almost impossible to see at times due to small size, and the 1.5 mm biopsy is preferred in most cases. The common punch size used to diagnose most inflammatory skin conditions is the 3.5 or 4 mm punch. [citation needed] [2]

In a sample of 100 Mohs surgeries, the total cost ranged from US$474 to US$7,594, with the higher costs for hospital-based complex procedures. In Australia, the direct out of pocket cost to patients may vary from $0 to $4000. When the non-Mohs surgery is performed by multiple doctors including pathologists the costs may be increased further.
The punch biopsy is used to enter the cyst cavity. The contents of the cyst are emptied, leaving an empty sac. As the pilar cyst wall is the thickest and most durable of the many varieties of cysts, it can be grabbed with forceps and pulled out of the small incision.
