Marjolin's ulcer
Medical condition
From Wikipedia, the free encyclopedia
Marjolin's ulcer refers to an aggressive ulcerating squamous cell carcinoma presenting in an area of previously traumatized,[1] chronically inflamed,[2] or scarred skin.[3]: 737 [4] They are commonly present in the context of chronic wounds including burn injuries, varicose veins, venous ulcers,[5] ulcers from osteomyelitis,[6] and post radiotherapy scars.
The term was named after French surgeon, Jean-Nicolas Marjolin, who first described the condition in 1828.[7] The term was later coined by J C De Costa.
Presentation
Histology
Histologically, the tumour is a well-differentiated squamous cell carcinoma. This carcinoma is aggressive in nature, spreads locally and is associated with a poor prognosis.[7] The cancer has a 18-38% rate of metastasis.[9] 40% occur on the lower limb and the malignant change is usually painless. This malignant change of the wound happens a long time after initial trauma, usually 10–25 years later. Its edge is everted and not always raised. More recent transcriptional analysis suggests that chronically impeded extracellular matrix turnover and epithelium-to-mesenchyme transitions in neglected scar tissue might give rise to this malignancy.[10][11]
