Hematoxylin-eosin–stained sections of the specimen were characterized by irregular, thick, eosinophilic, homogeneous-appearing elastic fibers in a background of abundant, sparsely cellular, delicate collagenous tissue with scattered pale-blue myxoid areas. The elastic fibers stained brown to black with Verhoeff elastin stain, and were curved, wavy, and frequently serrated. Many of these fibers were globular and appeared to be fragmented. At the margins of the lesion, trabecular extensions projected into the surrounding adipose tissue.
