Exacerbation of adenomyosis symptomatology by estrogen-progestin therapy: a case report and histopathological observations.

The present case report illustrates the hormonal sensitivity of adenomyosis. Administration of an estrogen-progestin combination for what was felt to be symptomatic endometriosis resulted in exacerbation of symptoms and growth of adenomyomas. Histopathologic examination of the hysterectomy specimen revealed a pattern of decidualization previously unreported, but consistent with current theories of experimental in vivo and in vitro decidua formation.
