A Unique Case of Late Presentation Giant Lower Extremity Malignant Melanoma

Abstract

This case describes a unique presentation of a rare malignancy: giant melanoma. Due to the accessibility of healthcare in the United States, it is unusual for melanomas to grow to massive sizes without clinical intervention. In fact, an in-depth literature review elicited only a handful of similar cases. Giant malignant melanomas are typically defined by a cutoff size of no less than 10 cm in diameter. They often present with distant metastases and are highly invasive. Due to limited yet highly variable presentations, there is no standardized approach to treating this class of melanomas. We present a case with unique features not previously documented in similar cases that was ultimately treated with a novel approach.
