Chromoanagenesis and Erythroderma as diagnostic clues in a critically ill patient

We report the case of a patient with severe multisystemic failure in which massive chromosomal changes in mosaic state were detected, which are considered to be associated with the possible underlying pathology: a T-cell lymphoproliferative syndrome. The patient also presented a case of Erythroderma of unknown cause several years earlier, with a progressive decline in her physical condition. The spectrum of clinical manifestations is then presented as a nonspecific paraneoplastic cutaneous picture of several years of evolution and findings of chromoanagenesis in the last phase of a lymphoproliferative morbid process. The new techniques of genetic analysis make it possible to obtain data to clarify the diagnostic processes and to identify a serious disorganization of the genetic information considered to be responsible for neoplastic changes.
