Case 316

Surgical Pathology Case



A 52-year-old male, who in workup for preparation of left hand surgery, was found to have an abnormal chest x-ray, leading to a CT scan that showed a 2.6 cm speculated lesion in the superior segment of the right upper lobe, which was suspicious for carcinoma.



The segmentectomy specimen measures 8.5 3.0 1.0 cm and weighs 26.2 grams. Serially sectioning through the specimen reveals a well demarcated mass measuring 2.0 in greatest dimension. The mass is 0.2 cm underneath the pleural surface.
