Melanoma, a highly aggressive and deadly form of skin cancer, can manifest in unexpected locations, including the foot. Foot melanoma accounts for approximately 3-5% of all melanoma cases, with a disproportionately higher mortality rate due to delayed diagnosis and treatment.

Methods

This comparative case study examines two patients with melanoma located in the plantar heel, one with acral melanoma and the other with invasive melanoma. A comprehensive analysis of these two cases highlights the diagnostic and therapeutic challenges associated with this rare and aggressive disease.

Results:

Results

The case studies reveal the complexities of foot melanoma, emphasizing the need for early detection and treatment. The 5-year survival rate for melanoma is significantly lower when diagnosed at an advanced stage, underscoring the importance of timely intervention. Notably, both patients presented with non-specific symptoms, such as pain and non healing wounds, which delayed diagnosis. Imaging studies and biopsy results confirmed the presence of melanoma. The patients underwent surgical excision, and adjuvant therapy was considered. The outcomes highlight the importance of a multidisciplinary approach and prompt referral to specialized care.

Discussion:

Discussion

This research aims to contribute to the existing body of knowledge on foot melanoma, ultimately informing improved diagnostic and treatment strategies for this complex and often lethal condition. By examining the clinical presentation, diagnostic dilemmas, treatment outcomes, and patient-centered care, this study highlights the critical importance of enhanced awareness among healthcare professionals and the general public.
