This is a case description of a single male patient found to have T-cell-mediated inflammation and lymphoproliferation of the orbit. Chronic T-cell-mediated inflammatory disease can pose a diagnostic challenge particularly in its differentiation from a neoplastic process. The histopathology in this case demonstrated features of both lupus erythematosus panniculitis and features of orbital T-cell lymphoma. While both are rare, lupus erythematosus panniculitis of the orbit is even more exceptional; this patient's indolent, chronic relapsing course distinguished itself from the typical aggression of orbital T-cell lymphoma. We believe this rare case may actually represent an example of a newly described disease spectrum that incorporates lupus erythematosus panniculitis as well as subcutaneous panniculitis-like T-cell lymphoma.
