The fine, tissue-associated filaments emphasized in Morgellons histology are small relative to the macroscopic follicular casts and comedo-like masses patients describe at symptomatic pores. Not every reported Morgellons fiber is microscopic, but no fiber of any size contains sensory nerves. Together, that scale difference and the need to locate sensation in surrounding living tissue make the intact follicle and its larger cast, plug, retained hair or mass the more plausible unit of study.
