[Pseudoplasmacytoma of the uterine cervix]

Report on a case of a 21 year old woman with a pseudoplasmocytoma of the cervix of the uterus. A tumour-like proliferation of plasma cells had developed in the area of a glandular ectopia of the cervix mucosa with a secondary erosion, which stretched continuously into the myometrium. The morphological changes were difficult to differentiate diagnostically from an extra-medullary plasmocytoma. After taking into account all histological and clinical data as well as the progression of the disease, the lesion was interpreted to be a well defined tumour-like reactive plasmocytosis of the cervix of the uterus.
