Giant malignant melanoma: report of a rare case

Abstract Background: Malignant melanomas generally carry a poor prognosis, an amplified concern in cases of neglected melanomas that progress to substantial sizes. The term giant melanoma typically refers to tumors measuring over 5–10 cm, which are of rare incidence and often associated with an especially unfavorable outcome. Clinical Case: A 45-year-old woman presented with an 18-month history of swelling on the sole of her right foot. The mass had grown rapidly over the preceding 3–4 months. On examination, a large, fungating lesion with satellitosis was observed over the plantar aspect of her right foot. Surgical excision of the mass was performed, and subsequent histopathological analysis confirmed the diagnosis of giant nodular melanoma (NM). Conclusion: This case illustrates a rare instance of giant NM with satellitosis, emphasizing the aggressive nature and poor prognosis associated with delayed presentation and advanced tumor size.
