Malignant melanoma of the scalp is a rare entity, representing an atypical location often associated with delayed diagnosis. This site poses a real clinical challenge due to its limited visibility and the difficulty of assessment, which can lead to late diagnosis and a more severe prognosis. We report the case of a patient presenting with a progressive pigmented lesion of the scalp, which was confirmed as malignant melanoma on histological examination. This case highlights the clinical and therapeutic specificities of this uncommon location. A review of the literature is also provided to better understand the diagnostic and prognostic challenges associated with this clinical form.
