title: Hydroxyapatite pseudopodagra. A syndrome of young women.
abstract: Six women with acute calcific periarthritis of the first metatarsophalangeal joint (hydroxyapatite pseudopodagra) are described, and 10 previously reported cases (8 female patients and 2 male patients) are reviewed. The onset was characterized by acute pain, swelling, erythema, tenderness, and limitation of movement of the first metatarsophalangeal joint, symptoms indistinguishable from those of gouty podagra, which is associated with transient amorphous calcific deposits in the vicinity of the joint. Based on these results it appears that hydroxyapatite pseudopodagra is a disorder that predominantly affects premenopausal women.
