title: [Sitting just hurts!].
abstract: We report on the history of a 53-year-old patient who went to his primary care physician due to pain while sitting. Clinical, gastroenterological and urological examination did not lead diagnostic. A radiography of the pelvis revealed a kinky sacrum and the MRT showed a tumor mass of about 9 cm in diameter. A plasmacytoma was histologically diagnosed in the biopsy.
