What should you know about regressed melanoma?

On the skin, regression may look like a pale, white, grey, pink, or scar-like zone within or beside a changing pigmented lesion. A dermoscopic examination can show features that suggest loss of pigment and altered skin structure. Regression can make the visible lesion look smaller than the original process, which is why the clinical history and the surrounding skin matter.

A biopsy examines the tissue that is sampled. If regression is suspected, the clinician may consider the lesion's most informative area and whether further surgery or staging is needed. A diagnosis of melanoma is based on the pathologist's findings together with the examination, not on fading alone.

Arrange a prompt review with a dermatologist, especially if the spot has changed in colour, outline, size, or texture. Bring older photographs if you have them and mention when the change began, whether the area has bled or crusted, and whether a previous biopsy or removal was performed.

Management may include a biopsy or Surgical Excision, followed by discussion of the confirmed depth and other pathology features. Depending on the findings, a Sentinel Lymph Node Biopsy or additional Skin Cancer Surgery may be considered. Treatment decisions are individual and should follow the pathology report.

Seek urgent medical advice for a rapidly changing lesion, repeated bleeding, an open sore that does not heal, marked tenderness, or a new firm lump near the site. New neurological symptoms such as severe headache, weakness, confusion, or a seizure need emergency assessment rather than routine skin review.

Ask which biopsy area was sampled, whether the report describes regression, and whether the margins are clear. Ask what follow-up schedule fits your result, whether lymph-node assessment is relevant, and which new skin or general symptoms should prompt an earlier appointment.
