A 79-year-old man presented with a gradually enlarging painless swelling around the right upper eyelid for over 1-year duration. On examination, a hard and non-tender mass noted over right upper eyelid, causing complete mechanical ptosis. CT scan revealed a well-defined enhancing lesion at the right upper eyelid, size measuring 0.9x2.4x1.4cm. Following excision biopsy, the histologic examination revealed fragmented tissue comprising mixture of dense chronic inflammatory infiltrates and scattered amorphous eosinophilic deposits. The deposits are surrounded by histiocytes and multinucleated giant cells. Special stain with Congo Red showed the deposits are non-congophilic. It is consistent with gouty tophus.
