Figure 6 The histological features are consistent with the presentation of hepatic solitary fibrous tumor. (A) The resected specimen. (B–F) Microscopic pathology. The tumor cells are short spindle-shaped or oval, arranged diffusely or in bundles (B), with areas showing higher cellular density (C) and others with lower cellular density (D). Abundant coarse collagen bundles (green arrow) are observed in the stroma (E). Characteristic “staghorn-shaped” blood vessels (yellow arrow) are visible within the tumor (F). B is 40×, C and D are 100×, E is 200×, and F is 400×. (G–I) Immunohistochemistry: CD34 (G) and STAT6 (H) are diffusely positive, and Ki-67 shows approximately 5% positivity in hotspot areas (I).
