a Clinical presentation at the first visit. The tumor was undergoing necrosis from the caudal with an offensive odor. b Necrosis stopped in conjunction with the chemotherapy cessation. c Computed tomography showed a low-density area on her left upper arm. d Contrast-enhanced computed tomography revealed one feeding artery branch from the subclavian artery into the tumor. e-g Histopathological examination of an excised specimen showed mature adipose tissue in the superficial and dermis with necrotic tissue (hematoxylin-eosin [H and E]) staining; in loupe (e), original magnification, x40 (f) and x200 (g)).

The tumor underwent necrosis from the distal aspect with an offensive odor (Fig. 1a). Necrosis stopped in conjunction with chemotherapy cessation due to the disease progression of pancreatic cancer (Fig. 1b). Contrast-enhanced computed tomography revealed one feeding artery branch from the subclavian artery into the tumor (Fig. 1c, d). Histopathological examination showed mature adipose tissue in the superficial and dermis with necrotic tissue without a thrombosis (Fig. 1e-g).
