When located on the lower limb, these resections can lead to large defects that require complex reconstruction in order to salvage the limb. The use of propeller-perforator flaps has multiple advantages such as the preservation of adjacent muscles, decrease in morbidity in the donor site, and good aesthetic and functional results. Our objective is to expose our experience and results with the use of propeller-perforator flaps for coverage of this kind of defects. Materials and Methods: Patients with malignant cutaneous melanoma of the lower limb who required reconstruction with a propeller-perforator flap between the years 2015 and 2021 in our plastic surgery department were included in this retrospective research. Demographic, reconstructive, oncologic, and functional data were collected and analyzed. Results: The cohort of 22 patients showed 100% of successful reconstructive outcomes. Only 2 patients experienced distal necrosis of the flap that was resolved with local dressings. Fast recovery and early capacity to walk were achieved in the majority of the patients with an average of 10.1 days until weight-baring walking. The 2-year overall and progression-free survival rates were 86.37% and 81.82%, respectively. Conclusion: The use of propeller perforator flaps for oncological defects coverage in the lower limb location has to be considered as a reliable choice as it takes less surgical time and a faster recovery. It allows limb salvage with an adequate length and functionality, with minimal donor site morbidity and a lower index of complications, contributing to improve patient’s quality of life and not delaying other oncological treatments.

It is a highly aggressive disease that develops from chronic wounds. Almost 65% of these lesions have been diagnosed on underlying burn scars. Although the mean latency time between the primary lesion and the apparition of the ulcer is around 25 years, some cases with an early debut have been described. Squamous-cell carcinomas arising in chronic wounds are typically aggressive and are related with a poor prognosis due to their late diagnosis. Therefore, it is important to recognize symptoms that indicate malignant degeneration of chronic wounds, allowing the clinician to make an early diagnosis in order not to delay the surgical treatment that is required to improve the global survival of the patient. The time elapsed between our patient’s burn and the appearance of Marjolin’s ulcer was only 7 months, drawing attention to its fast and aggressive progression.
