Histology Slide

摘要

A 45 year old Black female without significant past medical history was admitted with insidious cough, dyspnea, nausea, vomiting, and progressive weight loss. She suddenly went into respiratory distress and succumbed to death. Autopsy subsequently showed widespread granulomatous disease. This slide of one of the lung lesions shows a noncaseating granulocyte with a fibrotic center surrounded by palisading histiocytes, consistent with a diagnosis of nodular sarcoma.
