1.Moderate cellularity, clear background with mature-looking lymphoid cells 2. A loosely cohesive malignant epithelial cell cluster –Large irregular nuclei –High N/C ratio –Scant cytoplasm –Conspicuous nucleoli –Incipient rosette formation –Nuclear molding Positive for malignancy, metastatic carcinoma, poorly differentiated

Primary lung cancer Primary unknown carcinoma, metastasis to lung Mesothelioma, less likely

Non-small cell carcinoma –Squamous cell carcinoma –Adenocarcinoma Small cell carcinoma Differential diagnosis Adenocarcinoma, poorly differentiated Small cell carcinoma

AdenocarcinomaSmall cell carcinoma Large irregular nuclei OO High N/C ratio OO Scant cytoplasm O Conspicuous nucleoli O Incipient rosette formation OO Nuclear molding O

Diagnosis Metastatic poorly differentiated carcinoma, see note. Note) Biopsy is recommended.
