We report 6 new cases of adenoid cystic carcinoma (cylindroma) of the uterine cervix (5, invasive cancer and 1, in situ cancer). All 6 patients were elderly women and 5 were hypertensive. Additionally, 3 (Patients 1, 2, and 4) were obese and 1 (Patient 3) had diabetes mellitus. Three patients were seen because of postmenopausal vaginal bleeding and 3 were found to have malignant cells on routine exfoliative cytologic examination. Histologically, the tumor cells were relatively uniform, with scanty cytoplasms and a palisading pattern at the periphery of the tumor masses. Round cystic spaces were found in all 6 cases and hyaline nodules were present in some of the cyclic spaces in 2. The tumors were found in Stages IA, IB, IIB, IIB, and IIIB (cases 1-4 and 6 respectively), and were treated with irradiation only. There have been only 38 cases of invasive adenoid cystic carcinoma of the cervix reported in the world medical literature. We review the treatment and survival for all 38 cases previously reported and add 5 new cases.

Very late recurrent invasive squamous cell carcinoma of the cervix (over 10 years) after successful initial radiation treatment is a very rare occurrence (∼0.5%). Even though the treatment of choice has been radical surgery, there are a number of patients in whom surgery was regarded as undesirable. Ten such patients were reirradiated for these late recurrences after the full course of irradiation some 10 or more years ago. Six patients (six of ten) survived disease‐free several years, while the remainder experienced relief of their symptoms. Factors determining success and failure are: (1) the extent of the recurrence (clinical stage); (2) the degree of tumor necrosis; (3) status of normal surrounding tissues; and (4) radiation treatment and doses, integration and individualization of the external beam and brachytherapy. Criteria for patient selection and treatment technique are discussed.
