Results of a study of 44 @entity1 with @entity6794 ( @entity6794 ) are presented. Each @entity1 was diagnosed using standardized diagnostic criteria and followed up systematically. Thirty @entity1 were @entity1 and 14 @entity1 . Their mean age was 50 years (range 11-80). Twenty @entity1 had idiopathic and 14 parainflammatory occurrences (e.g. @entity31 , @entity30 ), whereas in 10 @entity1 an associated @entity66 or @entity5 was noted. Whereas @entity6794 was found predominantly in @entity1 , the association with @entity66 occurred more often in @entity1 . The lower legs and feet represented the typical predilection sites. Fifty-two per cent of @entity1 had one lesion, 37% had up to five, and 11% had more than five lesions. Histologically, lymphocytic and/or @entity1333 was present in 73% of the biopsy specimens obtained from the borders of the lesions. Long-term follow-up (n = 42, median follow-up 26.5 months) revealed that eight @entity1 had died, in six cases due to the @entity6794 and/or the underlying diseases. Of the remaining 34 @entity1 , 44% are in complete remission without further treatment, whereas continuing therapy is needed in 56%. No difference between @entity6794 was demonstrable in the follow-up and in no @entity1 with idiopathic @entity6794 was a possibly related disease diagnosed in the follow-up. These data suggest that @entity6794 should be considered to be an independent disease and not a purely cutaneous complication in most @entity1 .
