melanoma houstonMelanoma is a serious form of skin cancer that, if not caught early, can be deadly. While Melanoma only accounts for 5% of skin cancer diagnoses, it’s responsible for 75% of skin cancer deaths. Houston dermatologist Dr. Perri first became interested in the field of dermatology when an early Melanoma diagnosis saved his father’s life. Dr. Perri is well educated on the many different types and treatments of Melanoma skin cancer.

About Acral Lentiginous Melanoma

One particularly distinct form of Melanoma is Acral Lentiginous Melanoma, which is a rare form of Melanoma of the palms of the hands, fingernails and toenails or soles of the feet. Acral Lentiginous Melanoma is uncommon in Caucasians but is the most common subtype in people with darker skin tones, including African-Americans and Asian-Americans. Unlike normal Melanoma, which typically starts in a mole, Acral Lentiginous Melanoma can begin in a mole or in normal-appearing skin.

What does Acral Lentiginous Melanoma Look Like?

Acral Lentiginous Melanoma starts off as an increasingly enlarging patch of discolored skin. Most people think of the discoloration as a stain. Acral Lentiginous Melanoma can be identified by the ABCDEs of Melanoma, which are:

  • A is for Asymmetry. Like other forms of skin cancer, Acral Lentiginous Melanoma is asymmetrical. If you cut a line in the middle of it, the two sides will look different.
  • B is for Border. Houston patients will notice that Acral Lentiginous Melanoma’s borders are jagged and uneven. They may even have scalloped or notched edges.
  • C Stands for Color

Acral Lentiginous Melanoma skin cancer usually contains a mixture of colors, typically black, brown, blue-gray and red.

  • D Stands for Diameter

Benign moles are usually smaller in size, typically about 6mm in diameter and no bigger than the eraser on your pencil. But Acral Lentiginous Melanoma is much larger, often several cms larger at the time of diagnosis.

  • E Stands for Evolving

Just like with all cases of Melanoma skin cancer, one of the biggest warning signs of Acral Lentiginous Melanoma is that it evolves, or changes over time. Any type of change is troublesome, including a change in size, shape, color, and elevation or even if the spot has recently started bleeding, itching or crusting. In the case of Acral Lentiginous Melanoma, the spot typically starts out with a smooth surface at first but later transforms to a thicker lesion that may become dry or have a wart-like appearance.

Dr. Perri will perform an annual skin cancer screening, checking your body from head to toe, while paying careful attention to the spots that are troublesome to you. If after his exam, he suspects you have Acral Lentiginous Melanoma, he will schedule a biopsy.
