Calcifying pulmonary metastases
Calcifying pulmonary metastases are rare. These should not be confused with metastatic pulmonary calcification.
Calcification in metastases can arise through a variety of mechanisms: bone formation in tumours osteoid origin, calcification and ossification of tumour cartilage, dystrophic calcification and ossification of tumour cartilage, dystrophic calcification and mucoid calcification.
A number of primary malignancies can potentially cause calcification. The reported spectrum includes metastatic nodules from 3
- mucinous type carcinomas
- thyroid cancer
- treated metastatic choriocarcinoma
- giant cell tumour of the bone
