A Case of Acquired Angioedema Leading to the Diagnosis of Systemic Lupus Erythematosus

We describe a case of a young 32-year-old Indian female who presented with a solitary symptom of facial swelling for two months. The patient's blood test results showed hypocomplementemia and C1 INH deficiency and fell into the "third type" of acquired angioedema (AAE), leading to the diagnosis of systemic lupus erythematosus (SLE), with SLE inactivity at the time of presentation, which makes this an interesting case due to the rarity of such findings in our clinical settings.
