UNASSIGNED: @entity14938 are among the most common eyelid lesions presenting to eye care providers. Often successfully managed conservatively, some require more invasive intervention such as incision and drainage or @entity479 injection. Lesions that recur, do not respond to treatment, or are atypical in appearance or natural history should prompt more thorough analysis, often with biopsy and subsequent microscopic analysis. Not uncommonly, such atypical @entity14938 may be masking a more serious diagnosis. Eyelid @entity957 masquerading as a chalazion is exceedingly rare. We present a case report of an atypical chalazion that was refractory to incision and drainage as well as intralesional @entity479 injection. Incisional biopsy revealed the lesion to be a @entity957 requiring full-thickness excision and subsequent reconstruction. The @entity1 provided written informed consent, and the contents herein are acceptable under the provisions of the institutional review board. Following Mohs excision and oculoplastic reconstruction with a Hughes flap, the @entity1 has had a good outcome and is currently free of recurrence. Recurrent @entity14938 that are defiant to surgical and medical interventions should prompt biopsy and evaluation by pathology. @entity957 should be considered in the differential diagnosis as early intervention can save a @entity1 's eye and, not infrequently, their life.
