Idiopathic facial aseptic granuloma (IFAG), originally known as pyodermite froide (cold pyoderma), is a painless, benign facial condition most commonly occurring during early childhood with an age range between 8 months and 13 years. One or more nodules and sometimes papules are typically found on the cheek or eyelid. They are red or purple in appearance and may have a hard or soft, elastic consistency, or feel fluctuant.

The pathogenesis of IFAG is unknown, and no common predisposing factors including family history or prior trauma have been consistently associated. It has been hypothesized that IFAG may be due to a reactive process around an embryological remnant or may be related to granulomatous rosacea given its association with chalazia.
