Malignant Melanoma
Aggressive skin cancer arising from melanocytes, often redundantly termed as editors should note 'melanoma' alone implies malignancy.
Full Definition
Malignant melanoma is an aggressive form of skin cancer that arises from melanocytes, the pigment-producing cells in the skin. While 'malignant melanoma' is commonly used in clinical documentation, the term 'melanoma' alone is preferred as it inherently implies malignancy. The tumor has high metastatic potential and requires prompt surgical excision with appropriate margins. Staging involves assessment of thickness (Breslow depth), ulceration, and lymph node status, with sentinel lymph node biopsy often performed for intermediate-thickness lesions.
Usage
Usage note: Editorial preference is 'melanoma' alone; 'malignant melanoma' is redundant but still acceptable.
