Contrasting presentations of the same disease: A comparison of two cases of amyloidosis presenting with eyelid involvement.

PURPOSE

Localized amyloidosis can affect numerous tissues throughout the body and can also affect a variety of peri-ocular tissues including the conjunctiva, extra-ocular muscles, peri-orbital soft tissue, and lacrimal gland. We report two cases of amyloidosis presenting with eyelid involvement.

OBSERVATIONS

The first case represented a more subtle presentation of skin thickening with a pre-septal cellulitis, while the second case had a dramatic presentation of edema evolving into tissue dehiscence and spontaneous hemorrhage with ongoing angioedema and systemic coagulopathy.

CONCLUSIONS AND IMPORTANCE

The two cases of biopsy-proven orbital/peri-ocular amyloidosis demonstrate the different clinical presentations that may go from the subtle to dramatic, depending on which peri-ocular tissues are affected and to what degree. Standards for treatment of amyloidosis remain conservative initially with surgery or radiation recommended only for refractory cases, but additional therapies are under investigation. Clinicians should have high clinical suspicion for amyloidosis with findings such as skin thickening or significant periorbital edema and should always consider tissue biopsy and further workup for amyloidosis if the findings worsen or do not resolve with treatment of more common conditions such as cellulitis.
