title: [Sexually transmitted infections as a cause for solid rectal pseudo tumors].
abstract: Two cases of symptomatic proctitis with rectal tumors suspicious for malignancy are presented. A florid regenerative proctitis was shown in the histological examination. In both cases a sexually transmitted infection (STI) was causing the symptoms. In rare cases STIs present as pseudo tumors mimicking malignancy in clinical examination and endoscopic/radiological analysis. A close collaboration between gastroenterologist and pathologist is necessary for a correct diagnosis and to prevent unnecessary surgical treatment.
