Rationale and background: Diabetes Mellitus (DM) is a disease that leaves no tissues or organ of our body unaffected. The changes found in the skin are largely parallel to those occurring in internal organs. Objective: This study was carried out to study the types of cutaneous manifestations and their prevalence in diabetic children with cutaneous diseases in comparison with control patients with cutaneous diseases attending the pediatric dermatology out patient clinic. Patients and methods: This hospital based study was conducted on 304 Egyptian children (152 diabetic patients and 152 non diabetic patients both suffering from cutaneous diseases). Both diabetic patients and control patients were subjected to personal history and clinical examination. Results: The results showed that complications of insulin therapy in diabetic children had highest incidence (28.9%), followed by allergic skin diseases (19.1%). Pruritus came in the third order (15.1%) followed by cutaneous bacterial infections (12.5%) then cutaneous fungal infections (11.2%). While in control cases, allergic skin diseases showed the highest incidence (28.9%), followed by cutaneous bacterial infections (14.5%), parasitic infestations (11.2%) and sweat rash (10.5%). Conclusion: From the present series we can conclude that complications of insulin treatment especially lipohypertrophy was the most prevalent cutaneous manifestation among diabetic children. Generalized idiopathic pruritus was a common cutaneous symptom among Type 1 diabetic children. Type 1 diabetic patients were less prone to develop eczema, on the other hand
