Where are Merkel cells found?
Merkel cells are found in the top layer of the skin. These cells are very close to the nerve endings that receive the sensation of touch. Merkel cell carcinoma, also called neuroendocrine carcinoma of the skin or trabecular cancer, is a very rare type of skin cancer that forms when Merkel cells grow out of control.
What is the process of finding out if a cancer cell has spread to other parts of the body?
The process used to find out if cancer has spread to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease.

What is the treatment for regional nodal recurrence?
Treatment options for patients with only regional nodal recurrence include RLND and adjuvant radiation therapy if the regional draining nodes have not been previously treated. Because of the poor prognosis after recurrence, consideration can also be given to systemic chemotherapy, although there is no evidence that it improves survival.
What are the prognostic parameters of MCC?
The most significant prognostic parameters for MCC include tumor size and the presence of locoregional or distant metastases. These factors form the basis of the American Joint Committee on Cancer staging system for MCC. [ 59, 60] Although an increasing primary tumor size correlates with an increased risk of metastatic disease, MCC tumors of any size have significant risk of occult metastasis, supporting the use of sentinel lymph node biopsy for all cases. [ 61] Additional features of the primary tumor, such as lymphovascular invasion and tumor growth pattern, may also have prognostic significance. Clinically detectable nodal disease is associated with worse outcome than microscopic metastases. [ 55, 59] Other findings associated with worse prognosis include sheet-like involvement in lymph node metastases and an increasing number of metastatic lymph nodes. [ 60, 62]
Where does MCC occur?
MCC occurs most frequently in sun-exposed areas of skin, particularly the head and neck, followed by the extremities, and then the trunk. [ 5, 16, 19] Incidence has been reported to be greater in geographic regions with higher levels of ultraviolet B sunlight.

How to diagnose Merkel cell carcinoma?
Diagnosis. Tests and procedures used to diagnose Merkel cell carcinoma include: Physical exam. Your doctor will examine your skin for unusual moles, freckles, pigmented spots and other growths. Removing a sample of suspicious skin. During a procedure called a skin biopsy, your doctor removes the tumor or a sample of the tumor from your skin.
What is the procedure to remove lymph nodes?
The surgeon most often uses a scalpel to cut away the cancer. In some cases, your doctor may use a procedure called Mohs surgery.
What is the procedure called when you remove a tumor from your skin?
During a procedure called a skin biopsy, your doctor removes the tumor or a sample of the tumor from your skin. The sample is analyzed in a laboratory to look for signs of cancer.
What is sentinel node biopsy?
Sentinel node biopsy. A sentinel node biopsy is a procedure to determine whether cancer has spread to your lymph nodes. This procedure involves injecting a dye near the cancer. The dye then flows through the lymphatic system to your lymph nodes. The first lymph nodes that receive the dye are called the sentinel nodes.
What is radiation therapy?
Radiation therapy. Radiation therapy involves directing high-energy beams, such as X-rays and protons, at cancer cells. During radiation treatment, you're positioned on a table and a large machine moves around you, directing the beams to precise points on your body.

What is the margin of Merkel cell carcinoma?
Since the recurrence rate of Merkel cell carcinoma is very high, it is also important to have an optimal surgical margin that ranges from 1-3 cm whenever feasible. Even after wide local excision, the rate of local recurrence for the cancer is around 25-40%. Another surgical option is Mohs micrographic surgery ...

What Is The Best Treatment For Merkel Cell Carcinoma?
The best treatment and also the treatment of choice for Merkel cell cancer is surgical treatment. Surgical resection of the nodule or small tumor in stage 1 and 2 remove it completely and prevent any further growth or spreading of it. An excision margin of 2-3 cm is to be kept while removing it.
Conclusion
Although Merkel cell carcinoma is a rare tumor with a poor cure rate in late stages and is widely spreading when left untreated but complete cure is possible in it if detected early. Surgical resection of the cancerous nodule is the treatment of choice and performing further lymph node resection neck dissection, etc. is done in high-risk patients.

Can MCC be treated?
If MCC has spread to other parts of the body, treatment can often help control the cancer and ease symptoms, but these cancers are very hard to get rid of completely. Not all doctors agree on the best way to treat these cancers, so if time permits it’s often a good idea to get a second opinion from a team of experts.
How is cancer treated?
The main tumor on the skin is treated with surgery (usually wide local excision) to try to remove all of the cancer. If the cancer is in a place where removing it with a wide margin of normal skin would be difficult, Mohs micrographic surgery might be used.
Can radiation therapy help with cancer?
Surgery and/or radiation therapy might be used, but the goal is usually to ease symptoms rather than try to cure the cancer. Chemotherapy can often shrink or slow the growth of the cancer for a time and can help relieve symptoms. But chemotherapy can also cause side effects that need to be taken into account.
