Imaging
Those who care for patients with pulmonary, critical care or sleep disorders rely heavily on chest radiology and pathology to determine diagnoses. The Southwest Journal of Pulmonary, Critical Care & Sleep publishes case-based articles with characteristic chest imaging and related pathology.
The editor of this section will oversee and coordinate the publication of a core of the most important chest imaging topics. In doing so, they encourage the submission of unsolicited manuscripts. It cannot be overemphasized that both radiologic and pathologic images must be of excellent quality. As a rule, 600 DPI is sufficient for radiographic and pathologic images. Taking pictures of plain chest radiographs and CT scans with a digital camera is strongly discouraged. The figures should be cited in the text and numbered consecutively. The stain used for pathology specimens and magnification should be mentioned in the figure legend.

Medical Image of the Week: Lepidic Growth
Figure 1. Two different tumors showing lepidic growth along the alveolar interstitium with preserved alveolar architecture.
Lepidic growth is most often seen in adenocarcinoma in situ (Figure A, 40x magnification). Adenocarcinoma in situ is formerly known as bronchoalveolar cell carcinoma (BAC). A similar growth pattern in a morphologically very different tumor (mucinous adenocarcinoma) is shown for comparison (Figure B, 400x). Mucinous adenocarcinoma growing on alveolar septae nearly always is invasive, so the entity of mucinous adencioarcinoma in situ practically doesn't exist, further differentiating this entity from BAC.
