A 53 year old man presented with a cyst on his left cheek. The lesion was excised and submitted with a postoperative diagnosis or "epidermal inclusion cyst."
The specimen is received in formalin labeled "cyst in left cheek." It consists of a folded and curled, translucent pale tan membrane with attached tan-yellow fibroadipose tissue, 0.8 x 0.7 x 0.3 cm in aggregate. The specimen is entirely submitted.
Representative microscopic images of H&E stained sections are shown below in Figures 1 through 3.
