Abstract

Squamous cell carcinoma (SCC) has been commonly reported by foot and ankle specialists. Marjolin's ulcer is a malignancy that involves a posttraumatic scar or ulceration that can develop into SCC from chronic neuropathic pedal wounds, venous stasis, or decubitus ulcerations. Most Marjolin's ulcers are found in the lower extremity, specifically the feet, and it is twice as common in females as males. Biopsy of the tumor is the reference standard to diagnose SCC, and wide excision of SCC is the most common treatment option. The present case study describes an 83-year-old diabetic wheelchair-bound female who presented to the wound care clinic with a right heel nonhealing pressure ulceration. After biopsy and surgical excision, the patient was found to have SCC. This case was followed up for 5 years in which the patient had successful excision of the tumor with no recurrence. The clinical significance of our case study is to assist in the diagnosis, management, and prognosis of patients with SCC. In addition, this study has shown that adequate excision of the tumor margins and depth is necessary to prevent potential recurrence and metastasis.
