Introduction And Importance:
Nodular melanoma is the second most frequent cutaneous melanoma worldwide and due to its rapid growth rate and non-malignant appearance, is the most aggressive one. In its polypoid form, it is usually found in mucosal areas, but can also be seen on the trunk. This case is presented because it is an unusual manifestation and surgical treatment required wide excision, however, the patient's evolution is favorable.
Case Presentation:
70-year-old female patient shows a progressively growing lesion with irregular border, abnormal color and a heterogeneous appearance. The biopsy yields the histological diagnosis of nodular polypoid melanoma. The surgical technique results in the resection of a 10 × 9 × 67 cm piece with favorable evolution of the patient.
Clinical Discussion And Conclusions:
The surgical technique of margin widening is considered a recommended option for polypoid nodular back melanomas. Although the excision is considered vast, the patient's evolution may turn out to be favorable.
