Merkel Cell Carcinoma of Right Upper Eyelid, Including Canthus

Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer that arises from the Merkel cells of the skin. The incidence of MCC is increasing, and it is now considered one of the most lethal skin cancers. MCC of the eyelid is particularly rare, and involvement of the canthus, the corner of the eyelid where the upper and lower eyelids meet, is even rarer.

The symptoms of MCC of the eyelid may include a painless nodule or lump that grows rapidly, ulceration, and bleeding. The tumor may be pigmented or non-pigmented. MCC of the eyelid can be difficult to diagnose, and it is often misdiagnosed as a benign lesion. Therefore, a biopsy is necessary to confirm the diagnosis.

1. Risk Factors: The risk factors for MCC include advanced age, fair skin, immunosuppression, and exposure to ultraviolet radiation. Patients who have had organ transplants, have HIV/AIDS, or are on immunosuppressive medications are at increased risk of developing MCC.
2. Treatment: Treatment for MCC of the eyelid typically involves surgical excision. Radiation therapy may be necessary in some cases. The prognosis for MCC of the eyelid is generally poor, with a high risk of recurrence and metastasis.
3. Prevention: Prevention of MCC of the eyelid involves sun protection, including wearing hats and sunglasses, using sunscreen, and avoiding tanning beds. Patients who are at increased risk of developing MCC should have regular skin exams and report any suspicious lesions to their healthcare provider.

In conclusion, MCC of the eyelid, including the canthus, is a rare and aggressive skin cancer that requires prompt diagnosis and treatment. Patients who are at increased risk of developing MCC should take precautions to prevent skin cancer and have regular skin exams to detect any suspicious lesions.
