24 year old female. ThinPrep papA. LactobacillusB. GonorrheaC. TrichomonasD. Bacterial VaginosisE. Artifact 1
24 year old female. ThinPrep papD. Bacterial Vaginosis –
coccobacilli cover the squamous cells. Also called “Clue cells” 1
2
43 year old male. FNA of neck massA. Nematode wormB. RhabdomyosarcomaC. Normal muscleD. Squamous cell carcinomaE. Colloid
2
43 year old male. FNA of neck massC. Normal muscle – strips/chunks of
muscle with peripherally placed nuclei and striations
3
57 year old male. Urine cytology
A. Reactive urothelial cellsB. High grade TCCC. Low grade TCCD. Squamous cell carcinomaE. Polyoma virus
3
57 year old male. Urine cytologyE. Polyoma virus – enlarged cell with
smudgy intranuclear inclusion. Do not mistake for High grade TCC!
4
62 year old female. Peritoneal fluidA. Positive for tumor - AdenocarcinomaB. Reactive mesothelial cellsC. AtypicalD. Positive for tumor – LymphomaE. Benign lymphocytic effusion
4
62 year old female. Pleural fluidA. Positive for tumor - Adenocarcinoma “Cannonball” group of epithelial cells with
large nuclei and distinct cell borders. Pleomorphism and irregular nuclear membranes are seen. Patient had history of breast cancer.
5
53 year old female. Pleural fluidA. Positive for tumor - AdenocarcinomaB. Reactive mesothelial cellsC. AtypicalD. Positive for tumor – LymphomaE. Benign lymphocytic effusion
5
53 year old female. Pleural fluidA. Positive for tumor – Adenocarcinoma Large pleomorphic single cells with secretory vacuoles c/w adenoca. Signet rings forms are noted. Pt also has history of breast cancer. Don’t miss single malignant cells in effusions!
6
36 year old female. Thyroid FNAA. GoiterB. IndeterminateC. Positive for tumor – papillary
thyroid carcinomaD. Positive for tumor – follicular
carcinomaE. Hurthle cell neoplasm
6
36 year old female. Thyroid FNAB. Indeterminate – multiple
microfollicles with no colloid in the background. This is suspicious for a potential follicular neoplasm. On cytology we call this indeterminate because we cannot determine whether this is a follicular adenoma or a follicular carcinoma (for which you need to see either capsular +/or vascular invasion on histo)
7
60 year old male s/p bilateral lung transplant. BAL
A. AspergillusB. CandidaC. PCPD. MucorE. Fusarium
7
60 year old male s/p bilateral lung transplant. BAL
A. Aspergillus – septated hyphae with 45 degree branching
8
29 year old female. ThinPrep pap
A. ReactiveB. Endocervical cellsC. ASC-USD. LSILE. HSIL
8
29 year old female. ThinPrep pap
D. LSIL – enlarged nuclei with koilocytic change. Also have binucleates
9
63 year old male. FNA of lungA. AdenocarcinomaB. Squamous cell carcinomaC. Small cell carcinomaD. BACE. Reactive lymphocytes
9
63 year old male. FNA of lungC. Small cell carcinoma – note the
molding
10
26 year old female. ThinPrep papA. LSILB. HSILC. Endometrial cellsD. Squamous cell carcinomaE. Tubal metaplasia
