Im: Case no. 3: Metastatic lung basaloid squamous cell carcinoma in the septum and apex of the heart - Imaging. a - Cardiac CT: Four chamber view demonstrating hypodense round masses in the interventicular septum (red arrows). b - Cardiac MRI: Four chamber view, delayed enhancement; (normal muscle is hypo-intense - black), two enhancing foci (white) are demonstrated in the interventricular septum (red arrows). Fig. 3 H: Case no. 3: Metastatic lung basaloid squamous cell carcinoma in the septum and apex of the heart - Histology. This lung carcinoma is composed of monomorphic cells with moderate amount of cytoplasm and small prominent nucleoli growing in a trabecular-like pattern. Positive immunosatining for CK 5/6 and p63 demonstrate the basaloid features and enhance the trabecular-like growth pattern. Positive immunostaining for CD56 highlights some neuroendofrine features. a - HE X400. b – Immunosatin for CK5/6 X400. c - Immunosatin for p63 X400. d - Immunosatin for CD56 X400
