Background. Advanced stages of plantar acral lentiginous melanoma are common in Africa. Inguinal lymph node dissection (ILND) in these cases plays a critical role in disease-free and overall survival. Our study aims to share our experience in ILND for advanced plantar melanomas. Methods and Study Design. Four-year prospective study. Patients. We included all documented cases of advanced stage plantar melanoma with clinically detectable inguinal lymph node metastasis. Twenty-two of 27 patients identified—with mean age 56 years—underwent ILND. Studied Variables. Tumor patterns and stage, surgery, morbidity, oncologic pathology, and evolution were studied. Statistical software assessed the overall survival (OS). Results. Plantar lesions were all excised with a cancer-free margin (3 cm). ILND was performed for 22 patients with visible (n = 11), palpable (n = 7), and ulcerous (n = 4) lymphadenopathies. It was performed through an S-shaped (n = 11) or ellipse-shaped skin incision (n = 11). The tumors were AJCC stage III (n = 18) and IV (n = 2). We found high Breslow index tumor thickness (>3 mm) and an advanced Clark IV stage (n = 20). All operative wounds healed within 46 days (21–90). Wound healing was delayed by suture failure (n = 16), lymphorrhoea (n = 22), and infection (n = 18). After 29 months, three patients had complete remissions, seven had recurrences, and twelve patients had died. The overall survival (OS) at one year was 56%. In two patients with AJCC stage III disease, the OS was better (22 months). Conclusion. In low-income countries, ILND in advanced stages of plantar foot melanoma is a valuable surgical treatment option. Alongside ILND adjuvants, treatment must be available and accessible to improve survival.

Background In developing countries, the long delays in consultation lead to a delay in diagnosis and management of the skin tumors. The lesions are often large and bring the problem of skin coverage after their resections. Several reconstruction techniques allow skin coverage. The objective of this study is to describe the place of O-to-Z technique in the surgical treatment of skin cancers in Ouagadougou. We hypothesized that O-to-Z technique reduces healing times and the number of dressings compared with directed wound healing. Patients and methods It was a two-center, retrospective, descriptive study on O-to-Z technique in skin cancers. It included patients who underwent surgery between January 1st, 2013 and March 30th, 2021 in Ouagadougou. Scar quality and healing time in Z-plasty were compared with those of secondary healing. We used the Student’s t test. Results In 8 years and 3 months, 171 skin cancers were identified. The mean time to consultation was 13.6 months. The average size of the tumors was 9 cm. An O-to-Z technique was performed in 42 cases, being 58.3% of the patients operated on. The average healing time was 15 days. It was four and a half times shorter in O-to-Z technique than in secondary healing. Ischemic necrosis of the Z-corner was noted in 7 cases. The recurrence rate in O-to-Z technique and secondary healing was 7.1% and 9.1% respectively. Hypertrophic or keloidal scars were noticed in 7 cases and hypochromia in 2 cases. Conclusion O-to-Z technique is a technique of choice for skin coverage after large resections in surgical oncology. It reduces the healing time and the cost of postoperative care without increasing the risk of tumor recurrence.
