Rare Presentation of Melanoma Recurrences With Diffuse Subcutaneous Intravascular Lesions: A Novel In-Transit...

In 4%-11% of cases, melanoma recurrences present as in-transit (IT) metastases, and their prognosis is quite poor. Consequently, an early diagnosis and treatment of IT metastasis assume paramount significance. Despite this, the diagnosis of cutaneous IT metastases persistently presents a formidable challenge due to the diversity in clinical and dermoscopic characteristics. We provide a novel melanoma IT metastases pattern with interesting dermoscopic features and magnetic resonance imaging via presenting an unusual case characterized by diffuse subcutaneous intravascular lesions to supplement the understanding of cutaneous melanoma IT metastases.
