Adenocarcinoma lung, hypertrophic osteoarthropathy
Updates to Study Attributes
Right middle lobe bronchus occluded by a mass. Distal drowned airways, collapse &and consolidation. Within the collapsed middle lobe is a necrotic mass causing the fissures to bulge.
Right hilar and mediastinal lymphadenopathy.
Expanded lytic left rib lesion.
Right adrenal mass.
Updates to Case Attributes
Primary adenocarcinoma was diagnosed by lung biopsy, - stage IVb due to multiple extra-thoracic metastases (bone and adrenal). The left knee pain was caused by metastatic destruction of the subarticular medial femoral condyle.
Layered periosteal new bone is typical of hypertrophic osteoarthropathy, a recognised paraneoplastic effect of lung cancer.
Omission errors and satisfaction of search: Initially it was assumed that the pain was due to HOA or inflammation in the knee joint. The metastasis was missed due to failure of perception (omission error) and the presence of multiple abnormalities (satisfaction of search).
