“…In a study of 32 patients with polymyositis/dermatomyositis, 20 had B‐cell lymphoma, four had T‐cell lymphoma, and two had Hodgkin's lymphoma . In single cases, B‐cell lymphoma manifested with isolated myositis of a single extra‐ocular muscle . Non‐Hodgkin lymphoma may directly develop inside the muscle.…”

“…In recent large cohort studies, no case of ocular adnexal MALT lymphoma involved the extraocular muscles primarily [ 3 – 8 ]. There have been a few isolated case reports in the literature about biopsy-proven ocular adnexal lymphoma with discrete involvement of the extraocular muscles [ 9 – 11 ]. Studies have listed conjunctival injection, pain, and proptosis as the main symptoms.…”

Background Extraocular muscle is usually affected by thyroid disease or inflammatory pseudotumor, but seldom by neoplastic process. Primary malignant lymphoma involving isolated extraocular muscle is very rare, especially after 6 years of chronic myositis. Case presentation A middle-aged female presented with swelling of the lower lid of the right eye for 2 months. Magnetic resonance imaging showed significant enlargement of the right inferior rectus muscle belly. The patient first presented 6 years prior with upper eyelid swelling. A total of 5 surgical biopsies of the right eye were performed during 6 years with the following successive findings: inflammatory pseudotumor, chronic inflammation, inflammatory lesions, IgG4-related ophthalmic disease, and lastly, extraocular muscle extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma). Conclusion MALT lymphoma may have occurred as a result of chronic extraocular myositis. Malignancy should be considered in patients with recurrent painless extraocular muscle hypertrophy. Differential diagnosis can rule out thyroid-associated ophthalmopathy (TAO), whose symptoms are similar. Diagnosis confirmation by biopsy is warranted if necessary.

“…In a case report, a complex periosteum and orbital floor elevation and excision was conducted to gain access for an inferior rectus muscle biopsy (7), which might present difficulties for inexperienced surgeons. Moreover, the actual incisional procedure of EOM is not commonly described (8–9–10); therefore, we suggest standardizing the method.…”
