Bullous diabeticorum is a rare skin condition that is associated with uncontrolled diabetes mellitus, characterized by spontaneous blister formation mainly on hands or legs . We present a case of a 58-year-old male with type 2 diabetes who developed tense blisters on his right leg without any preceding trauma. Diagnosis was confirmed through clinical and histopathological examination, revealing subepidermal blisters. Management focused on supportive care and blood glucose control, leading to resolution of lesions over several weeks. This case emphasizes the need for awareness of bullous diabeticorum in diabetic patients, facilitating timely diagnosis and preventing unnecessary interventions.
