SQUAMOUS CARCINOMA, 50209/82

50209/82         SQUAMOUS CARCINOMA

 

The patient was a woman aged 74.

 

The specimen is a slice of the right lung. There is a spherical tumour mass occupying a substantial portion of the upper lobe. The tumour is grey and well circumscribed. A nearby lymph node contains a metastasis. Histology showed that this was a squamous cell carcinoma. The remainder of the upper lobe is consolidated and has the golden-yellow colour of lipoid pneumonia. In this condition the alveoli are filled with foamy macrophages containing lipid droplets within their cytoplasm. The lipid in this instance is of endogenous source coming from the local breakdown of tissue.
