I confess my only experience with such material is in the form of
chicharrones (fried pork rinds), but one of the worst of surgical
specimens is similar - skin with underlying fat, in large specimens
from melanoma resections.

I can only advise fixing in neutral buffered formalin until the fixed
tissue is hard enough to gross into very thin sections (no thicker
than a nickel), followed by further overnight fixation in the same
