The patient at birth had multiplex anomalies: poikilodermatous rash, sceletal abnormalities: palatoschisis, micrognathi, aplasia radii, hypoplastic right and left thenar and thumbs, pesequinus on both site, ectopy renis. The patient in the later ages was detected dental malformation, facial dysmorfism. At the age 3, she had lasion in her muscle. After biopsy, histological examination showed cutan T-cell lymphoma. The patient is the first case who had cutan T-cell lymphoma associated with RTS in this young age.展开更多
