Fig. 3From: Two cases of radiation-associated angiosarcoma of the breastMacroscopic and microscopic pathological findings (case 2). a The nodule was diagnosed as angiosarcoma by open biopsy (H.E. staining: × 20). b Mapping biopsy 5 cm from the surgical trace (H.E. staining: × 20). Arrow: atypical endothelial cells. c Mapping biopsy 10 cm from the surgical trace (H.E. staining: × 20). Arrow: atypical endothelial cells. d Mapping biopsy was performed 5 cm and 10 cm away from the surgical trace. The red dots indicate areas where atypical endothelial cells were observed, and blue dots indicate areas where no atypical endothelial cells were observedBack to article page
