Squamous cell carcinoma arising from a recurrent ischial pressure ulcer: a case report.

ABSTRACT

Marjolin's ulcer is the malignant transformation of long-standing chronic pressure ulcers and requires prompt diagnosis and treatment. A 46-year-old man with an 8-year history of traumatic spinal injury with paraplegia presented with a recurrent ischial pressure ulcer. The initial ulcer, which developed 6 years earlier, was a Stage IV sacral ulcer. The wound was debrided and pathology showed epithelial hyperplasia, acanthosis, hyperkatosis accompanied by mild inflammation, and fibrosis without any malignant transformation. The lesion was covered with a fasciocutaneous bipedicled flap. Four years later, the patient presented with a similar ulcer in the same location. Histology showed the presence of a well-differentiated squamous cell carcinoma (SCC). Following a wide excision, the lesion was covered with a gluteal maximal V-Y musculocutaneous advancement flap. At last follow-up 14 months postoperatively, there was no evidence of recurrence or metastatic disease. Clinicians must be aware of known risk factors for the development of SCC.
