Cardiac Hemangioma in the Left Ventricular Septum

Figures

• 

  Fig. 1. Preoperative transesophageal echocardiography confirms the tumor at the left ventricular septum, measuring 3 × 2 cm (projection at the mid-esophageal level).

• 

  Fig. 2. Preoperative positron emission tomography computed tomography (PET-CT) shows the cardiac mass, which appears to be connected to the left ventricular septum with mild metabolic activity.

• 

  Fig. 3. Macroscopic view. The largest dimension of the specimen was 4.2 cm. The surface appeared to be covered by the endothelium and the myocardial muscle. The cut surface showed a well-demarcated spongiotic, reddish colored lesion.

• 

  Fig. 4. Histopathological view. On overview, histology shows a well-demarcated lesion with capillary and cavernous areas. The lining is characterized by flat cells without atypia and immunohistochemical confirmation of endothelial differentiation. The K i -67 immunohistochemistry underlines the low proliferative nature of the lesion.
