paratesticular leiomyoma

Tuesday 20 December 2011


- bilateral paratesticular leiomyoma (16236398, 16950754)


- der(14)t(12;14)(q15;q24) (21962898)

- complete androgen insensitivity syndrome (CAIS) (16950754, 16236398)


- t(5;14)(q31;q24)
- t(12;14)(q15;q24)

  • strong immunohistochemical nuclear expression of the HMGA2 protein
  • HMGA2 as the target gene in 12q14∼15 rearrangements.
  • In uterine leiomyomas, the t(12;14)(q15;q24) is the most frequent translocation leading to overexpression of HMGA2.
  • It seems that a common pathogenetic pathway exists for benign smooth muscle tumors of both the female and male reproductive organs.
