Amelanotic malignant melanoma explained

The word malignant is already part of what melanoma means: this is a cancer of melanocytes. Lack of brown or black colour can make visual recognition harder, and diagnosis depends on clinical assessment followed by examination of sampled tissue.

Amelanotic melanoma can present as an enlarging pink bump, a reddish patch, a changing skin-coloured lesion or a sore that bleeds or does not settle. Melanoma may present with these changes, but each can also occur in non-cancerous or other skin conditions.

A dermatologist considers change over time, shape, surface, firmness and subtle areas of pigment rather than relying on colour alone. A biopsy allows a pathologist to assess the cells and use additional laboratory stains when the appearance is unclear.

Book a skin assessment for a new or changing lesion that persists, particularly one that grows, crusts or bleeds. Record its location and changes, and bring dated photographs if you have them. Avoid trying to burn, cut or treat the spot at home because this can delay diagnosis and alter its surface.

If biopsy confirms melanoma, the report helps guide further removal and whether staging is appropriate. Care may involve dermatology, surgery and oncology. The team will explain margins, wound care, examination of lymph nodes and a follow-up schedule based on the complete findings.

Seek a prompt appointment if a lesion is changing quickly, repeatedly bleeding without clear injury, developing an open surface, or becoming a firm growing lump. Urgency follows the concerning change itself; appearance cannot confirm the cause.

After a melanoma diagnosis, report a new lump near the treated area or in the armpit, groin or neck. Emergency care is appropriate for sudden weakness, a seizure, confusion or a severe new breathing problem.

Ask whether the entire lesion was sampled, what the pathology report shows, whether another procedure is advised, and how your skin and lymph nodes should be checked. Clarify which wound changes require a call and who will organise ongoing reviews.
