*"Cellular" is something that can be subjective. One definition of "cellular" is: "stromal cells are touching one another". Jacobs ''et al.'' has a stromal cellularity picture gallery showing ''mild'' (rare stromal cells touching), ''moderate'' and ''marked'' (many stromal cells touching).<ref name=pmid16191502>{{Cite journal | last1 = Jacobs | first1 = TW. | last2 = Chen | first2 = YY. | last3 = Guinee | first3 = DG. | last4 = Holden | first4 = JA. | last5 = Cha | first5 = I. | last6 = Bauermeister | first6 = DE. | last7 = Hashimoto | first7 = B. | last8 = Wolverton | first8 = D. | last9 = Hartzog | first9 = G. | title = Fibroepithelial lesions with cellular stroma on breast core needle biopsy: are there predictors of outcome on surgical excision? | journal = Am J Clin Pathol | volume = 124 | issue = 3 | pages = 342-54 | month = Sep | year = 2005 | doi = 10.1309/5N2C-4N5X-CB8X-W8JL | PMID = 16191502 }}</ref> | |||

====Micro==== | |||
The sections show a lesion with a pale mildly cellular stroma, and bland glandular elements. No apparent proliferative activity is present. The border is well-circumscribed where seen. Focally, the lesion approaches the inked margin; partial lesion transection cannot be excluded. | |||
No cytologic atypia is present. No leaf-like architecture is present. No stromal overgrowth is seen. No calcifications are evident. No large cysts are seen. | |||
