lepidic growth in pulmonary adenocarcinoma, lepidic growth pattern


- pulmonary adenocarcinoma

  • pulmonary adenocarcinoma with prominent lepidic spread
  • The percentage of the lepidic component appears to be an independent, significant prognostic factor in a selection of pulmonary AC. (26159539)

- lepidic pulmonary metastasis from cholangiocarcinoma


- Adenocarcinoma with predominant lepidic growth pattern, Case 210

  • Core biopsy: the prominent intra-alveolar growth with papillary projections into the alveoli indicates that this is likely an invasive neoplasm.
  • That this is indeed invasive adenocarcinoma is indicated by the appearance of the mass on the CT scan as well as by a separate small tissue fragment from this specimen showing unequivocal invasive adenocarcinoma.
