Clinical History:
79 year old postmenopausal woman, being evaluated for possible Squamous cell carcinoma of vulva

NILM: Atrophy

Cytomorphologic Criteria:
Sheets of uniform orderly parabasal cells are observed representing deep parabasal cells. Some nuclei show grooves, but chromatin pattern is fine. Atrophic cells may have nucleoli (lower right insert).

Explanatory Notes:
Differentiate from HSIL by uniform bland nuclei and orderly cell arrangement. Background clues may be helpful.
