Large left atrial myxoma with synchronous laryngeal squamous cell carcinoma: A case report

Figure 4 Histopathological findings of the left atrial tumor. A: On macroscopic examination, cut sections show a predominantly hemorrhagic appearance with some pale yellow myxoid areas. No fleshy areas are identified (scale included at the bottom of the image); B: Low power microscopic examination shows stellate, ovoid, and plump spindle cells set in a vascularized myxoid stroma [hematoxylin and eosin-stained slide (HE) 50 × magnification]; C: The cells are singly dispersed, and arranged in perivascular rings around small blood vessels (HE-stained slide, 200 × magnification); D: There is no high-grade cytological atypia. There is prominent intratumoral hemorrhage and hemosiderin deposition. Mixed inflammatory infiltrate is noted (HE-stained slide, 400 × magnification).
