@entity5 @entity1 @entity957
We have studied the incidence of internal @entity5 on @entity1 with @entity957 ( @entity957 ). This incidence has been compared to expected number of @entity5 in that population by a precise statistical analysis. Two-hundred and eighty-three @entity957 confirmed by histology are diagnosed on 235 @entity1 (159 @entity1 , 76 @entity1 ). These @entity1 have been followed between December 1970 and November 1982 at the specialized consultation on cutaneous @entity5 . We have examined all these @entity1 , questioned their doctors, consulted their medical case history, to search an internal @entity5 . Twenty-eight @entity1 had a @entity5 : this @entity5 has been found 11 times before and 17 times at the same time or after @entity957 . These 17 @entity5 are the only statistically interesting cases. The annual incidence of @entity5 related to age and sex has been evaluated by consulting French registers. The French incidence has been compared to foreign incidences. This incidence enables us to calculate the expected observed numbers (12 and 5). The expected numbers are 9.15 for @entity1 and 2.1 for @entity1 . These numbers are not statistically different from observed numbers (12 and 5). The incidence of internal @entity5 on @entity1 with @entity957 is not different from the incidence of general population.
