The patient had been seen by an ophthalmologist at another hospital. The initial diagnosis was idiopathic orbital pseudotumor. Steroid therapy did not resolve clinical symptoms. Her medical history held decisive clues: ten years before this presentation she had been diagnosed with double primary breast cancer, invasive lobular breast carcinoma, and invasive ductal breast carcinoma. Orbital biopsy was performed for differential diagnosis.\u003Cbr>Discussion: Considering the rapid onset and severity of symptoms, the radiological features of the orbit, and the patient's medical history of breast cancer, orbital metastasis should have been the most likely diagnosis. Orbital biopsy was performed because of the history of multiple primary cancers and because metastatic origin had to be determined to define the best treatment strategy.\u003Cbr>Conclusion: Biopsy is necessary under specific circumstances in the diagnosis of orbital metastasis, especially when presentation is ambiguous and when differential diagnosis is challenging. A patient's medical history may hold vital clues to correct diagnosis. |\n\n1. Introduction  \nOrbital metastases (OM) account for 4 to 8 % of orbital neoplasms. In almost 40 % of cases, orbital metastases derive from breast carcinoma [1,2], making breast cancer the most common malignancy to spread to the orbit [2]. It has been vastly observed that breast cancer is a rather heterogenous disease: cancers can differ in biology, responsiveness to therapy, survival rate, and metastatic behavior. The two breast cancer subtypes most often diagnosed are invasive lobular carcinoma (ILC) and invasive ductal carcinoma (IDC). ILC accounts for 10 to 15 % of all breast cancers, while IDC accounts for 50 to 70 %. ILC is known to be less respondent to neoadjuvant therapy than IDC [3]. The risk of death at 10 years is 50 % higher for ILC patients than for those affected by IDC [4]. Finally, the two types of breast cancer metastasize differently to the orbit: a metanalysis of 72 case reports by Raap et al. found that 15 % of orbital metastases were due to ILC whereas only 3 % were related to IDC  \n[5]. In addition, ILC has a five times greater propensity to metastasize to the orbit than IDC [2,5]. Regarding unusual metastatic sites, the orbit accounts for 25 %, followed by the stomach (23 %), and the rectum (8 %), demonstrating the peculiar organotropism that ILC has for orbital tissues [5].
