| Case | Clinical history | Requester | Diagnosis |
|---|---|---|---|
| Case | Clinical history | Requester | Diagnosis |
|
| 19 yo M with large right subpectoral mass with numerable bilateral pulmonary nodules | null | Small round blue cell neoplasm (permanent dx: synovial sarcoma • monophasic spindle-cell type) |
|
| 56 yo M with right lower lobe lung tumor | null | High-grade malignancy • favor carcinoma (permanent dx small cell carcinoma) |
|
| 72 yo F with R apical lung nodule | null | Fibroelastotic scarring; negative for malignancy |
|
| 59 yo F with 3.5 cm left upper lobe lung mass | null | Lung parenchyma with extended alveolar spaces with mucin and a focus of atypical epithelium lining alveolar walls away from margin |
|
| 41 yo F never smoker with 6.5 cm right upper lung mass invading the mediastinum and extending to right hilum with mediastinal adenopathy and enlarged supraclavicular lymph node | null | Atypical cells suggestive of non-small cell carcinoma (permanent dx: classic Hodgkin lymphoma) |
|
| 56 yo F with lung nodule | null | Atypical pneumocyte proliferation associated with lymphoplasmacytic inflammation (permanent dx: adenocarcinoma) |
|
| 70 yo F with lung nodule | null | Adenocarcinoma • 0.5 cm from parenchymal margin |
|
| Hemothorax; pleural biopsy | null | Fibrous and organizing pleuritis with abundant acute inflammation. No granulomas. No evidence of malignancy |
|
| 68 yo M with RUL mass | null | Small cell carcinoma with significant crush artifact |
|
| 49 yo M with anterior mediastinal mass | null | Poorly differentiated carcinoma |
|
| 72 yo F with 1.7 cm solitary lung nodule; former smoker • history of breast cancer | null | Organization pneumonia; negative for malignancy |
|
| 64 yo F with lung nodule | null | Carcinoid tumor |
|
| 71 yo M with large left hilar mass and mediastinal lymphadenopathy; 4R lymph node | null | Metastatic poorly differentiated carcinoma (permanent dx: small cell carcinoma) |
|
| 65 yo M with LLL mass; 4R lymph node | null | Positive for neoplasia with epithelioid features (permanent dx: Metastatic poorly differentiated adenocarcinoma consistent with lung primary) |
|
| 57 yo M with tracheal mass (no prior biopsies) | null | Small focus of adenoid cystic carcinoma present in the adventitia |
|
| 72 yo M with pleural effusion; pleural biopsy | null | No definitive malignancy • some atypical cells • favor reactive mesothelial cells; chronic inflammation (permanent dx: chronic pleuritis with multiple lymphoid follicles and mesothelial hyperplasia) |
|
| 75 yo F with lung nodule | null | Organizing pneumonia with chronic and histiocytic inflammation with atypical pneumocytes • favor reactive atypia (Permanent dx: Fibroinflammatory nodule; there is no evidence of malignancy) |
|
| 58 yo F with lung nodule | null | Low grade spindle cell neoplasm (Permanent dx: Smooth muscle neoplasm; no over features of malignancy; may represent benign pulmonary leiomyoma which is exceptionally rare; metastasis from other sites including cutaneous and uterine origins should be clinically excluded; benign metastasizing leiomyoma of the uterus cannot be excluded) |
|
| 15 yo M with anterior mediastinal mass | null | Germ cell tumor (Permanent dx: yolk sac tumor) |
