Figure 1. Histology of pre-invasive bronchioloalveolar carcinoma and invasion in AdCa.

Figure 1

(A) BAC shows irregularly collapsed slightly thickened alveolar walls.

(B) Alveolar walls are lined by uniform low columnar neoplastic cells.

(C) Microinvasive AdCa with a predominant BAC/lepidic pattern and a solid area (arrowhead).

(D) The solid area in (C) shows irregular glands amidst a fibroblastic stroma.

(E) Irregular angulated glands in a fibrous stroma within an invasive focus.

(F) The extent of the invasive focus (black circle) seen in (E). The black line represents the linear measurement of invasive size.
