title: Primary systemic amyloidosis: a unique case complaining of diffuse eyelid swelling and conjunctival involvement.
abstract: A 52-year-old Japanese woman with the chief complaint of marked swelling of her upper eyelids and a mass over the bulbar conjunctiva is reported. She previously noticed frequent purpura after minimal trauma, which was resolved shortly after taking some ascorbic acid. Laboratory data showed Ig-G kappa type M-protein in the serum and kappa type Bence-Jones protein in the urine by immunoelectrophoresis. Systemic examination showed mild hepatosplenomegaly, 1st degree of AV block, and a mild increase in plasma cells in the bone marrow biopsy. Histologically, the whole dermis of the eyelid skin and conjunctiva was replaced by a large quantity of amorphous, eosinophilic substances, which were diffusely positive with Direct Fast Scarlet 4BS. Immunohistochemical staining was positive for anti-amyloid P component antibody. Typical amyloid fibrils were proved by electron microscopy. She was finally diagnosed as primary systemic amyloidosis with diffuse swollen eyelids and conjunctival mass, symptoms which in primary systemic amyloidosis are very rare.
