Default SCC-PthRP-hypercalcemia

Lung

Squamous cell lung carcinoma

Photograph of a squamous cell carcinoma. Tumour is on the left, obstructing the bronchus (lung). Beyond the tumour, the bronchus is inflamed and contains mucus.


When associated with the lung, it often causes ectopic production of parathyroid hormone-related protein (PTHrP), resulting in hypercalcemia.
