Figure 7. Histology findings. (A) Elongated, thin, and tapered cells of uniform appearance with pale cytoplasm and embedded in a collagenous stroma. No nuclear hyperchromasia, cytological atypia, or mitosis. Blood vessels are thin-walled with perivascular edema and vascular microhemorrhages. (B) Nuclear β-catenin staining is observed. Smooth muscle actin (SMA) was weakly positive and desmin fixation was negative. DNA sequencing revealed that the CTNNB1 (β-catenin) gene carried the p.T41A (c.121A>G) mutation.
