Abstract
1) The in situ carcinoma is suggested to be a malignant lesion that may be histologically differentiated from carcinomimetic and heteroplastic lesions (epidermizations and hyperplasia of the basal layers, trichomonas lesions).
2) Out of 1500 cases of invasive portio carcinoma, 10 in situ carcinoma have been observed, 4 of which were detected by re-examination of the bioptic material.
3) In these 4 untreated cases an invasive carcinoma developed in a period ranging from 1 year (2 cases) to 3 and 5 years.
4) In the remaining 6 cases, a simple total hysterectomy was performed in 5 patients and radiumtherapy in 1 case in which the carcinoma occurred on the cervical stump.
5) 18 cases of cervical lesions from trichomonas and 3 cases of gravidic changes of the portio are discussed.
6) According to the Authors, the in situ carcinoma requires a radical treatment (conservative total hysterectomy).
7) In cases of marked basal hyperplasia and carcinomimetic forms unresponsive to medical treatment, the cervical conization is suggested both for diagnostic and prophylactic scope.
