Case report: Study of a bulky melanoma mimicking sarcoma.

Introduction: Large melanomas, while relatively uncommon, present significant diagnostic challenges due to their size and potential to mimic other malignancies, leading to delays in appropriate treatment. Initial misdiagnosis is a substantial concern, impacting patient outcomes. This case highlights the importance of immunohistochemistry in cancer diagnosis, and of appropriate therapeutic management, which here included excision surgery of the tumor mass.
