Résumé
Musculoskeletal tumors are uncommon. However, the true burden of all bone and soft tissue tumors of extremities is underestimated. Usually, the diagnosis of sarcomas is missed or delayed. Therefore, an adequate clinical and radiological assessment, along with the awareness and application of simple guidelines for referral to a specialized center, are of utmost importance. These are critical steps for an appropriate diagnosis and treatment of sarcomas, improving their prognosis.

We report a rare presentation of an initially misdiagnosed case of a pseudotumor, which on histopathology was diagnosed as bilateral breast metastases of lobular carcinoma involving multiple extraocular muscles. A 61-year-old lady presented with external ophthalmoplegia and diplopia. Incisional biopsy was performed using a lid crease approach and the patient received radiotherapy and hormonal therapy. Following prolonged hormonal therapy, complete remission was achieved, with improvement in ocular motility and resolution of diplopia, about 18 months after the initial presentation. Multiple extraocular muscle involvement by breast carcinoma metastasis is very rare and should be considered in the differential diagnosis, especially in patients with a prior history of breast carcinoma.
