Detailed answer

Yes, hyperpigmentation can potentially be a symptom of malignant melanoma. Hyperpigmentation occurs when the skin produces more melanin, the pigment responsible for skin color. In some cases, malignant melanoma, a type of skin cancer that typically starts in the form of a mole or dark spot, can cause excessive melanin production, leading to hyperpigmentation. It is important to note that hyperpigmentation alone does not necessarily indicate malignant melanoma, as there are various other causes of hyperpigmentation such as sun exposure, hormonal changes, and certain medical conditions. Therefore, it is crucial to consult a healthcare professional for proper diagnosis and evaluation of any concerning skin changes or abnormalities.
