Type of Preparation:


Clinical History:
Postmenopausal female

NILM : Histiocytes

Cytomorphologic Criteria:
Histiocytes. These cells have moderate, often vacuolated cytoplasm and kidney shaped to oval vesicular nuclei. Nucleoli may be seen.

Explanatory Notes:
Histiocytes can be seen in postmenopausal and postpartum Pap tests and can be single or multinucleated. They may be also be seen secondary to other reactive/reparative processes. Superficial endometrial cells can resemble histiocytes. At low power, the differential diagnosis of single cells in a "streaming" pattern, often in mucus includes histiocytes, microglandular hyperplasia and even HSIL.
