mycosis fungoides

Variants

- folliculotropic mycosis fungoides (17721200)

Cytogénétique

Chromosome abnormalities, mostly complex karyotypes, are seen in about 50% of patients with MF/SS, and there have only been a few instances of recurrent rearrangements.

- 47% of abnormal karyotype by SKY/FISH (16382449)

  • chromosome 10
  • chromosome 6 (deletion)
  • chromosome 3
  • chromosome 7
  • chromosome 9
  • chromosome 17
  • chromosome 19
  • chromosome 1
  • chromosome 12
  • chromosome 8
  • chromosome 11
  • chromosome 13 (deletion)

- recurrent breakpoints

- pseudodicentric translocation between the short arms of chromosomes 8 - dic(17;8)(p11.2;p11.2) (16382449)
