==Pigmentation==
*Permanent abnormal discoloration
===Melanosis===
*Individual parenchymal lobules are affected
*Pigment is present in the alveolar walls of calves and lambs
*Most likely [[Lungs - developmental#Congenital melanosis|congenital]]
===Anthracosis===
*Diffuse greyish discoloration
Carbon in the connective tissue around airways and vessels, after being brought and deposited there - sequestration - by macrophages from the alveoli
*Used to be seen in town-dwelling dogs and cats
==Calcification==
*Generally associated with hypervitaminosis D or from ingested vitamin D analogues
*Common sequel to [[Kidney - Renal failure#Uraemia|uraemia]] in dogs and pulmonary necrosis
*Lungs may fail to collapse on opening the thorax
*See [[General Pathology - Pigmentation and Calcification#Calcification|general pathology]]
