Unusual Presentation of Giant Malignant Melanoma in the Deltoid: A Case Report and Review of the Literature

The term giant melanoma was previously characterized as a significantly large melanoma, often exceeding 10 cm in diameter. The present case report presents our experience in managing a giant malignant melanoma in the deltoid region in a 79-year-old patient. Due to the size of the lesion, surgical resection with reconstruction using the pectoralis major muscle flap to cover the defect was chosen. The results showed that experimental treatment regimens and new therapeutic agents and techniques should be considered, since giant melanomas are often associated with several negative prognostic factors. Therefore, more studies are necessary for a better understanding of this pathology, which requires a multidisciplinary team for its treatment.
