Marjolin's ulcer: a rare entity with a call for early diagnosis

Marjolin's ulcer (MU) is an umbrella term covering squamous cell carcinoma (SCC), basal cell carcinoma and malignant melanoma that develop in chronic wounds, sinuses or scars. Cutaneous (non-MU) SCC is related to excessive sun-exposure, with Fitzpatrick skin types I and II being more susceptible. Radiation, genetic disorders (eg, Xeroderma pigmentosum) and immunosuppression, are other important risk factors often involved in the development of cutaneous malignancies and may also be involved in the development of MU. MU, first described by Jean-Nicholas Marjolin in 1828, is more aggressive than non-MU SCC, with a higher potential for early metastasis. A high index of suspicion and early histological diagnosis in chronic wounds and unstable scars with recent changes in characteristics offer the best prognosis with treatment. We present a case alongside a literature review contrasting the characteristics of MU and non-MU SCC, and suggest a management plan for early MU identification and prevention.

[Marjolin's ulcer of the cheek developed on burn scar: a case report]

Marjolin ulcers are scar carcinomas most often arising in old burn injuries. They arise mostly in the extremities. We report medical history of a 50-year-old female suffering from a scar carcinoma on her right cheek which was histopathologically identified as a mean differentiated squamous cell carcinoma.

Treatment of skin cancers in epidermolysis bullosa

Squamous cell carcinomas (SCCs) are highly aggressive in patients with epidermolysis bullosa (EB). Non-ultraviolet-related SCCs are the leading cause of death in patients with recessive dystrophic EB, particularly recessive dystrophic EB-generalized severe subtype (RDEB-GS). The mechanism of SCC development in patients with RDEB continues to be investigated and several theories have been reported in the literature.
