PURPOSE: Granulomas resulting from the administration of luteinizing hormone-releasing hormone analogues (LH-RH analogues) are thought to be very rare. We report on our clinical experience with injection-site granulomas that result from the administration of LH-RH analogues, and we evaluate the incidence rate of these granulomas. MATERIALS AND METHODS: We used the clinical records of 118 patients who were administered LH-RH analogues in 2005. We describe the clinical data of patients who experienced injection-site granulomas and evaluated the incidence rate. RESULTS: Five patients demonstrated injection-site granulomas due to LH-RH analogue administration. The incidence rate was 4.2% (5 of 118 patients). Most of the granulomas occurred after the first or second administration of 11.25mg of leuprorelin acetate. CONCLUSION: The occurrence of granulomas resulting from the administration of LH-RH analogues was thought to be very rare. Our study, however, revealed a higher incidence rate than expected, especially for leuprorelin acetate.
