Bronchioloalveolar carcinoma: two clinical entities with one pathologic diagnosis

Expression of Thyroid Transcription Factor-1, Cytokeratin 7, and Cytokeratin 20 in Bronchioloalveolar Carcinomas: an Immunohistochemical Evaluation of 67 Cases

“…Type 1, or mucinous, BACs display goblet or mucin-producing cells, whereas Type 2, or nonmucinous, BACs show predominantly Clara cell or Type II pneumocyte differentiation. Tumors that exhibit both mucinous and nonmucinous histologic patterns have also been described (25,26).…”

Solitary Nodular Bronchioloalveolar Carcinoma of the Lung: Prediction of Histology at High-Resolution CT

“…Two blinded observers jointly analy zed the marginal and internal characteristics of nodules as seen on HRCT, and decisions on the findings were reached by consensus. Stepwise discriminant analysis for characteristic findings ofBAC was performed.Results (5,7,9). Reported CT findings of solitary nodular BAC include a peripheral subpleural location, internal bubble lucency or pseudocavitation, heterogeneous attenuation, irregular margins and pleural tag.…”

“…Results (5,7,9). Reported CT findings of solitary nodular BAC include a peripheral subpleural location, internal bubble lucency or pseudocavitation, heterogeneous attenuation, irregular margins and pleural tag.…”

“…With its favorable prognosis and distinctive radiologic features, solitary nodular BAC, the most commonly presenting form, is generally considered a separate clinical entity (5,7,9). Reported CT findings of solitary nodular BAC include a peripheral subpleural location, internal bubble lucency or pseudocavitation, heterogeneous attenuation, irregular margins and pleural tag.…”
