2E63.0Z/D03.9 Melanoma in situ of skin, unspecified



Melanoma in situ of skin, unspecified is an early form of skin cancer caused by the uncontrolled growth of pigment-producing cells (melanocytes) located in the outermost layer of the skin. It is caused by excessive exposure to ultraviolet (UV) radiation, either from natural sunlight or from artificial sources such as tanning beds.


The diagnosis of melanoma in situ of skin, unspecified is based on the appearance of the skin lesion, as well as its size, shape, color, and other characteristics. A biopsy of the lesion may be performed to confirm the diagnosis.

Differential diagnosis

Other skin conditions may be mistaken for melanoma in situ, including benign moles, freckles, and other skin lesions. It is important to distinguish between benign and malignant lesions as early diagnosis and treatment are essential for successful treatment of melanoma.


Treatment of melanoma in situ typically involves surgical removal of the affected area of skin. This may involve a wide excision of the skin surrounding the lesion or may involve a more limited excision of the lesion itself. In some cases, additional treatment such as chemotherapy or radiation therapy may be recommended.


The prognosis for melanoma in situ is generally good, especially with early diagnosis and treatment. If the melanoma is detected and treated in its early stages, the chance of complete cure is very high.
