Pulkit et al19 have reported similar findings with marrow infiltration in 54.5% cases, in patients under 5 years of age with males predominating, both marrow aspirate and trephines were infiltrated in 16 out of 24 positive cases with only aspirate positivity in 4 (9%) cases and isolated trephine positivity in another 4 (9%) cases, similarly another study conducted by Franklin et al20 reported bone marrow infiltration in 48.9% cases.
All cases of aplastic anaemia showed mainly fat in the trephine biopsy.
As a consequence, from that incidence on, we have always used single-use sharp trephines to achieve clean cutting edges in view of eliminating this possible problem.

The morphology was classic for MCC and similar in appearance to the nonhaematopoietic cell infiltrate present in bone marrow trephine.
Two round excision wounds including the epithelial margins were excised 5.0 mm in diameter with a sterile disposable biopsy trephine and a surgical blade.

Using a 6'mm trephine the cornea was penetrated in the paracentral area to a depth of 1/3 of the stromal thickness, creating a recipient bed for implantation of the free-omental graft (Figure 1A) or cells-containing AM (Figure 1B).
In this process, the first bur that entered was a trephine 2 mm in diameter that removed the basal bone and grafted from the maxillary sinus to then continue with the milling protocol according to the manufacturer and the installation of the dental implant.
