The tumor is waxy, firm, pale white or yellowish plaque and generally poorly defined borders, resembling localized scleroderma. A 60-year-old woman presented with a whitish, pearly indurated plaque on her back at the site of skin flap from her previous surgery. She had treated for recurrent BCC lesion with wide excision and rotation flap. Although the lesion was completely excised with 1 cm clearance margin, new lesion was developed at the prior treatment site. Histopathologic examination revealed elongated thin strands of tumor cells embedded in a dense fibrous stroma as that seen in morpheaform type. We present the case of a 60-year-old woman with a recurrent BCC appearing as morpheaform on her back at prior surgical site and we suggest Moh's micrographic surgery (MMS) would be warranted for a morpheaform BCC irrespective of body site.© 2010 Lippincott Williams & Wilkins, Inc.
