Simultaneous Development of Dieterich Disease and Freiberg Disease

Dieterich disease is an uncommon arthropathy of the hand, with few studies published. This lesion shares a similar etiopathogenesis with Freiberg disease, although the association of both conditions has only been described once. We report a 65-year-old man consulting for inflammatory pain in his right hand of 1 month's duration and also in his right foot of 4 months' duration. The rheumatology department was consulted to rule out systemic disease because the synovitis had occurred simultaneously in 2 different locations. The plain radiography and magnetic resonance imaging findings supported the diagnosis of Dieterich disease and Freiberg disease, although only increased uptake was found on scintigraphy in the affected zones. Few studies have been published about Dieterich disease, most in case report form. To our knowledge, only 1 study has described the association of Dieterich disease and Freiberg disease. Surgical treatment has been described when conservative management is unsuccessful, with multiple techniques used. The present case is the first in which Dieterich disease and Freiberg disease manifested simultaneously in the initial painful inflammatory phase.
