The hematoxylin-eosin–stained sections under low-power view showed a normal epidermis and a slightly fibrotic dermis. The reticular dermis was infiltrated with circumscribed nodules, separated from each other by fibrous tissue that extended down to the subcutaneous fat. The high-power view showed the presence of cuboidal and spindle-shaped cells arranged in a whorled pattern with nuclei containing diffuse chromatin with occasional small basophilic nucleoli. Rare mitoses were present. Within the center of the tumor nodules, prominent irregular vascular spaces lined by plump endothelial cells were seen. There was no surrounding inflammatory infiltrate. Masson trichrome stain revealed the presence of red-staining fascicles within a blue-green collagenous matrix.
