Objective: to describe and reclassify the diagnoses registered in the “other neoplasms” field of the histopathological examination reports in the Cancer Information System (Siscan), Brazil, 2031-2020. Methods: descriptive study based on examinations compiled of the cervix entered in the Siscan; a pathologist assessed the diagnoses and reclassified them based on the categories reported in the standardized form. Results: histopathological exams registered as “other neoplasms” represents 2.4% of all examinations reports (n = 5,778) of which 67.4% could be registered in the existing categories, 8.9% were “other neoplasms” and 24.5% were results not compatible with other neoplasms and that were not included in the existing options, such as benign findings or findings outside the cervix. Conclusion: the field for other malignant neoplasms is misused; the analysis highlighted the need to train professionals to properly use the system and include new categories in the form.
