I had a hard, small (about 1 mm diameter, 1 mm height)dark brown bump on my back. It was kind of bubble-shaped (not wide, but high, shaped like a cherry anginoma).I first noticed this about 9 months ago when it was not as large.
I was rubbing it yesterday, and it came off, the area was very red and the 1mm brown spot (without elevation) remains.
Could this be nodular melanoma, since it was hard, came off easily, and was elevated a lot with a small diameter?
Or since it was only about 1mm think would it not be nodular melanoma? I heard they are very wide (at least 6mm wide)?
I have an appointment with a dermatologist but not for a week, can you advise on this...
Melanomas do not rub off. You most likely have a Seborrheic keratosis. A seborrheic keratosis usually appears as a brown, black or light tan growth on the face, chest, shoulders or back. The growth has a waxy, scaly, slightly elevated appearance. Occasionally, it appears singly, but multiple growths are more common. Seborrheic keratoses don't become cancerous, but they can look like skin cancer.
