Painful orbital inflammatory lesions and mastocytosis.

A 15-year-old female patient developed painful nodules in an anophthalmic socket that were exacerbated by treatment with steroids and narcotics. Although orbit biopsy showed chronic inflammation, the diagnosis of mastocytosis was confirmed with skin biopsy and urinary levels of histamine. The patient responded to excision of nodules and treatment for mastocytosis. Painful orbital lesions associated with mastocytosis have not been reported previously.
