Ophthalmic Plast Reconstr Surg. 2020 Mar/Apr;36(2):e51-e53. doi: 10.1097/IOP.0000000000001567.

Abstract

Focal eosinophilic myositis (FEM) is a rare disease that is even more uncommon in affecting the periocular area. The authors are reporting the first case of FEM occurring in the lower eyelid of a 45-year-old Caucasian female who presented with localized painful area of glossy induration and peau d'orange skin lesion. Magnetic resonance image shows significant hyperintense thickening of the pre-septal orbicularis muscle region on T2-weighted images. Incisional biopsy of the induration revealed marked fibrinoid degeneration of the orbicularis muscle and adjacent fascia, mixed cellular infiltration of lymphocytes and eosinophils and a predominant CD8+ lymphocytic infiltrates in the immunohistochemical study. The final diagnosis was FEM. Oral prednisolone improved symptoms and the lesions disappeared, with no recrudescence in a one year follow-up.
