Abstract
Solitary fibrous tumor (SFT) is a relatively rare form of neoplasm that commonly occurs in the pleura. They
are mesenchymal in origin. Majority of this tumors are benign, some of them are malignant. Histologically,
they are characterized by “pattern less pattern” and hemangiopericytoma like appearance. Histological
differential diagnosis of SFT is broad because of high variability of their light microscopic appearance.1
Here we report a relatively rare case of 67-year-old male who presented with incidental pulmonary nodule.
After investigations, he was initially diagnosed as small cell neuroendocrine tumour (carcinoid tumour) but
finally diagnosed as a case of SFT on post wide resection biopsy of lung.
