Histologically, this malignant transformation is a well-differentiated squamous cell carcinoma [67] ; however, its behavior is very aggressive in pressure injuries, considerably more so than in burns or osteomyelitis. [68, 66] There is a high likelihood of nodal metastasis at the time of diagnosis. Any long-standing, nonhealing wound should alert the examiner to the need for biopsy.
