Merkel Cell Carcinoma of Left Upper Eyelid, Including Canthus

Merkel cell carcinoma is a rare and aggressive type of skin cancer that usually appears on sun-exposed areas of the skin, particularly on the head, neck, and arms. Merkel cell carcinoma of the left upper eyelid, including canthus, is an uncommon presentation of this type of cancer, and can be challenging to diagnose and manage.

Patients with Merkel cell carcinoma of the left upper eyelid may present with a painless nodule or lump that grows rapidly and ulcerates. The tumor can be mistaken for a benign cyst or stye, leading to a delayed diagnosis. Pathologic examination of biopsy specimens is required to confirm the diagnosis and to determine the extent of the tumor infiltration and involvement of adjacent structures.

Patients with Merkel cell carcinoma of the left upper eyelid may also experience symptoms such as blurred vision, tearing, and sensitivity to light. The tumor can invade the eye socket, optic nerve, or brain, leading to serious complications.

1. Risk Factors
• Exposure to ultraviolet radiation
• Age over 50 years
• Immunosuppression
• History of other skin cancers
2. Diagnosis
• Biopsy of the lesion
• Imaging studies such as CT or MRI
• Examination of the lymph nodes
3. Prognosis
• Depends on the stage and extent of the tumor
• Overall survival rate is about 50%
• Recurrence is common, and follow-up is necessary

Treatment options for Merkel cell carcinoma of the left upper eyelid, including canthus, depend on the stage and extent of the tumor, as well as the patient's overall health and preferences. Surgery, radiation therapy, and chemotherapy are the main treatment modalities, either alone or in combination. However, due to the complexity and delicate anatomy of the eye, specialized ophthalmologic and plastic surgery consultation may be necessary to ensure the best possible outcome.

In conclusion, Merkel cell carcinoma of the left upper eyelid, including canthus, is a rare and challenging cancer that requires early diagnosis and multidisciplinary management. Patients at high risk should be screened regularly, and any suspicious lesions should be evaluated promptly by a dermatologist or ophthalmologist.
