Fig 1 (A) Digital clubbing as the initial presentation of a non-small cell lung cancer (NSCLC) in a patient. Typical features of hypertrophic osteoarthrpathy are clinically visible. (B) Complete disappearance of digital clubbing 3 months following left upper lobectomy with mediastinal adenectomy and adjuvant chemotherapy. (C) Distant recurrence of NSCLC with no recurrence of digital clubbing.

Fig 3 (A and B) Primary lung tumor immunostaining for cyclooxygenase-2 (COX2) shows a clear patchy expression pattern including areas with sparse expression and areas with intense expression. (C and D) Brain metastasis immunostaining for COX2 shows no expression in any part of the lesion although the primary tumor positive control is visible.
