Pachydermoperiostosis Presenting With Vision Loss Secondary to Severe Phlyctenular Keratoconjunctivitis.

PURPOSE

To report a case of severe phlyctenular keratoconjunctivitis in a patient with pachydermoperiostosis (PDP).

METHODS

A 29-year-old Hispanic man presented with a 1-year history of vision loss in the right eye and redness, photophobia, and pain in both eyes. Associated symptoms included enlargement of his hands and feet for 3 years, acne, and joint pain. Examination was notable for severe meibomian gland dysfunction, corneal and limbal phlyctenules in both eyes, and central stromal scarring of the right cornea. He had cystic acne of the face and a coarse, wrinkled forehead and scalp. Examination of his hands and feet revealed clubbing of the digits.

RESULTS

The patient had an extensive laboratory workup that was significant for elevated erythrocyte sediment rate and C-reactive protein. X-ray of his hands and feet revealed diffuse periosteal hyperostosis with diffuse bone expansion. The patient was diagnosed with PDP with severe meibomian gland dysfunction, phlyctenular keratoconjunctivitis, and corneal scarring. His pain and photophobia resolved with medical management of the phlyctenular keratoconjunctivitis but decreased vision in the right eye persisted because of neovascularization and scarring of the cornea.

CONCLUSIONS

We report a rare case of phlyctenular keratoconjunctivitis associated with PDP. To our knowledge, this is the first case of PDP to initially present with vision loss.
