E-mail: med.benrejeb@gmail.com Case Presentation  A 9-year-old boy presented with a 4-month history of chronic nodular lesion on the cheek resistant to antibiot- ics. Dermatological examination showed a 15-mm, solitary, firm erythematous nodule on his right cheek (Figure 1a). A punch biopsy specimen revealed a dermal chronic inflam- matory, granulomatous perifollicularinfiltrate consisting of histiocytes, neutrophils, and giant cells without necrosis (Figure 1: b, c). Based on these findings,we diagnosed the case as idiopathic facial aseptic granuloma (IFAG). Teaching Point IFAG is a rare, benignpediatric entity characterized by chronic, painless erythematous-violaceous nodular lesions frequently located on cheeks and eyelids with no predispos- ing factor [1]. Although pathogenesis remains unclear, the disease is thought to be associated with granulomatous ro- sacea in childhood [1]. Histologically, IFAG lesion is char- acterized by a dermal chronic inflammation of histiocytic granuloma with giant cells, and abscesses without necrosis. In general, IFAG tends to resolve spontaneously in less than a year. Antibiotics, such as doxycycline and metronidazole, could be used to accelerate the involution of IFAG [2]. 2 Research Letter | Dermatol Pract Concept. 2022;12(2):e2022092 References 1.
