Lymphoma is the most common adult orbital malignancy making up about 10% of all orbital tumors, and 2% of all nodal and extranodal lymphomas [1–4]. The clinical signs and symptoms along with radiological findings are generally useful in suggesting diagnosis of the disease in the majority of cases before biopsy, although they are not reliable in making an accurate diagnosis [5–8]. Lymphoma can affect any of thevaried soft tissue structures in the orbital cavity in addition to bony changes and may therefore be mistaken for another disease process due to overlapping clinical and imaging features. Definitive diagnosis is made by: histopathology, immune-histochemical staining, and flow cytometry phenotype examination. Although CT and MR are widely accepted as giving optimal imaging for the diagnosis of orbital lymphoma, we did not find much in the literature dealingwith mistaken imaging diagnosis of adnexal lymphoproliferative disease [9–17]. L ymphomas are malignant tumors that develop from clonal proliferation of B lymphocytes; T lympho-cytes; and, less frequently, natural killer cells. They are divided into Hodgkin lymphoma (HL), which is of B-lymphocyte origin, and non-HL (NHL), which have different clonal origins and consist of B-cell lymphomas, T-cell lymphomas, and non-kill-cell lymphomas.1 Ocular adnexal lymphoma (OAL) is a form of lymphoma that localizes to the orbit, lacrimal gland, eyelids, and conjunc-tiva.2 Most OAL are extranodal NHLs.3 Lymphoma is the most common malignancy of the ocular adnexa, but only comprises 5%–10% of all extrano-dal lymphomas and 1%–2% of all NHLs.4,5 The frequency of involvement in periorbital sites has been studied to be approximately 46%–74% in the orbit, 20%–33% in the conjunctiva, 5%–10% in the lacrimal gland, and 5%–20% in the eyelid.6,7 The diagnosis is confirmed through biopsy of the lesion.7 OAL usually presents in the seventh decade of life and has a female predominance.8 Many cases are asymptomatic, but the most common presenting signs and symptoms are painless orbital mass with a “salmon-patch” appearance (67%), proptosis (54%), restriction of extra-ocular motility (39%), conjunctival swelling (22%), and irritation, tearing, headache, itchiness, diplopia, facial numbness, and pressure sensation. B symptoms, such as fever, night sweats, or weight loss, may also be reported.4,7 Given the slow-growing nature of OAL, coupled with its asymptomatic nature, lymphoma can easily be misdiag-nosed, leading to delays in diagnosis. This series empha-sizes the clinical course of identification and workup of four patients with periocular lymphomas and includes cases of primary, isolated, recurrent, and metastatic periorbital lymphoma. This information may aid plastic surgeons in developing a higher degree of suspicion to promptly perform comprehensive examinations, imag-ing studies, specialist referrals, and biopsies to establish a diagnosis.
