Abstract: BACKGROUND:IGM has a diagnostic and treatment dilemma. The etiology of IGM is unknown but some conditions have been discussed as predisposing factors including Oral Contraceptive Pills, pregnancy, breast feeding, reproductive age, hyperprolactinemia, infectious and autoimmune diseases. The current study aimed to determine possible risk factors for IGM and to evaluate our experience in its management. PATIENTS AND METHODS:The study included forty patients with IGM and forty females with normal breasts as a control group. CST treatment was initiated for all patients; patients who responded completely were followed up without surgical intervention. Failure to respond to medical therapy or incidence of corticosteroid-related complications were considered indications for surgical treatment. All patients were followed up for 6 months to detect recurrence. RESULTS:IGM had a significant higher incidence rate in young females within 5 years from the last lactation, smokers, those with hypperprolactinaemia, who had a history of breast feeding and those who received OCP (P = <0.001, <0.001, 0.006, 0.001, 0.023 and 0.027 respectively). The central part of the breast was more affected (9 cases (22.5%)). Multicenteric disease affected 8 cases (20%). Breast Mass was the most common presenting sign. After CST; the mass disappeared in 5 cases (12.5%), mass size reduced in 26 cases (65%) and mass size not affected in 9 cases (22.5%). Surgery was done in whom the mass size was reduced or not affected (35 cases (87.5%)). Disease recurrence was reported in 2 cases (5.7%). CONCLUSION:IGM usually affects females in their childbearing period with multiple risk factors mainly parity, smoking, OCP and breast feeding with wide variation regarding the presenting manifestations. We should start with CST as there is always a chance to avoid unnecessary surgery and combination of both modalities can reduce the incidence of recurrence.
