What is melanoma pathology?
For melanoma, such prognostic parameters include tumor thickness, ulceration, mitotic rate, lymphovascular invasion, neurotropism, and tumor-infiltrating lymphocytes. Disease staging is important for risk stratifying melanoma patients into prognostic groups and patient management recommendations are often stage based.
What does a pathology report tell you?
A pathology report is a document that contains the diagnosis determined by examining cells and tissues under a microscope. The report may also contain information about the size, shape, and appearance of a specimen as it looks to the naked eye. This information is known as the gross description.

Although tests aren’t 100% accurate all the time, receiving a wrong answer from a cancer biopsy – called a false positive or a false negative – can be especially distressing. While data are limited, an incorrect biopsy result generally is thought to occur in 1 to 2% of surgical pathology cases.
What biopsy reports tell?
For many health problems, a diagnosis is made by removing a piece of tissue for study in the pathology lab. The piece of tissue may be called the sample or specimen. The biopsy report describes what the pathologist finds out about the specimen.
What happens if biopsy report is positive?
Another important factor is whether there are cancer cells at the margins, or edges, of the biopsy sample. A “positive” or “involved” margin means there are cancer cells in the margin. This means that it is likely that cancerous cells are still in the body.
What is the prognosis of malignant melanoma?
Melanoma is the most lethal skin cancer that originates from the malignant transformation of melanocytes driver genes and immune checkpoints have substantially improved the prognosis of patients. However, the low response rate and inevitable occurrence
