Nodular Melanoma is a type of melanoma that is typically characterized by its rapid growth and vertical invasion. It is the second most common subtype of melanoma, accounting for approximately 15-30% of all cases.
Introduction[edit]
Nodular melanoma often presents as a firm, round or oval-shaped, darkly pigmented or occasionally amelanotic (lacking pigment) nodule. Unlike other types of melanoma, nodular melanoma tends to grow more vertically than horizontally, which can lead to a quicker invasion of the dermis and subcutaneous tissue. This rapid growth and invasion can make nodular melanoma more dangerous than other types of melanoma.
Symptoms[edit]
The most common symptom of nodular melanoma is a rapidly growing, darkly pigmented nodule. Other symptoms can include changes in the size, shape, or color of an existing mole, or the development of a new mole. The nodule may also be itchy or bleed.
Diagnosis[edit]
The diagnosis of nodular melanoma is typically made through a biopsy of the suspicious lesion. The biopsy is then examined under a microscope by a pathologist to confirm the diagnosis. Other diagnostic tests, such as imaging studies or a sentinel lymph node biopsy, may also be performed to determine the extent of the disease.
Treatment[edit]
The primary treatment for nodular melanoma is surgical removal of the tumor and a margin of normal tissue surrounding it. In some cases, additional treatments such as chemotherapy, immunotherapy, or radiation therapy may be recommended.
Prognosis[edit]
The prognosis for nodular melanoma depends on a number of factors, including the thickness of the tumor, the presence of ulceration, and whether the cancer has spread to the lymph nodes or other parts of the body.
