Bilateral Primary Mucinous Carcinoma of the Eyelid Treated with Mohs Surgery

Background: Primary mucinous carcinoma is an uncommon malignant cutaneous tumor which arises most commonly on the eyelid. While rarely causing death, recurrence following primary excision is common and widespread metastasis may occur.

Objective: We report the first case of bilateral primary mucinous carcinoma of the eyelid.

Methods: A lesion of the left lower eyelid had been resected three times previously with positive conventional margins. Both this lesion and a second primary lesion of the contralateral lower lid were removed with Mohs microscopically controlled excision without recurrence for more than 2 years.

Conclusion: Multiple lesions of mucinous carcinoma of the eyelid do not necessarily connote metastasis. Mohs microscopically controlled excision may be a suitable form of therapy for primary mucinous carcinoma of the eyelid.
