Merkel cell carcinoma (MCC) can mimic a chalazion in solitary eyelid nodules. Early diagnosis and aggressive treatment are crucial for this rare but aggressive cancer.
Area of Science:
- Ophthalmology
- Oncology
- Dermatopathology
Background:
- Solitary eyelid nodules can present diagnostic challenges.
- Merkel cell carcinoma (MCC) is a rare but aggressive skin cancer.
- Distinguishing benign from malignant eyelid lesions is critical for patient outcomes.
Observation:
- A 62-year-old woman presented with a rapidly growing violaceous eyelid mass.
- Initial diagnosis was a chalazion, but histopathology revealed Merkel cell carcinoma (MCC).
Findings:
- Histopathologic examination confirmed Merkel cell carcinoma (MCC) of the eyelid.
- The patient did not tolerate radiotherapy and succumbed to widespread metastases within 13 months despite chemotherapy.
Implications:
- Merkel cell carcinoma (MCC) should be considered in the differential diagnosis of solitary eyelid nodules.
- Prompt and aggressive management is essential for improving prognosis in eyelid MCC.
- This case highlights the importance of thorough histopathologic evaluation for eyelid masses.
