Final answer:
The symptoms described suggest a condition called melanoma, which is a type of skin cancer characterized by abnormal growth of pigment-producing cells in the skin. Melanoma often presents as large brown or black patches with uneven borders and a raised surface. The ABCDE mnemonic can help with its diagnosis.
Step-by-step explanation:
The symptoms described, such as well-demarcated hyperpigmented macules and patches, asymmetric distribution, and the appearance of various shapes, suggest a condition called melanoma. Melanoma is a type of skin cancer that is characterized by the abnormal growth of melanocytes, the pigment-producing cells of the skin. It often presents as large brown or black patches with uneven borders and a raised surface.
Doctors use the ABCDE mnemonic to help diagnose melanoma:
Asymmetry: The two sides of the mole are not symmetrical.
Borders: The edges of the mole have an irregular shape.
Color: The mole has varied shades of brown or black.
Diameter: The mole is larger than 6 mm (0.24 in).
Evolving: The shape of the mole has changed.
If you have any concerns about your skin, it is important to consult a doctor for a proper diagnosis and treatment.
