Abstract
- Interstitial granulomatous dermatitis (IGD) is a rare skin condition commonly associated with autoimmune diseases. Lesions typically occur bilaterally on the lateral trunk and proximal extremities and present as variable cutaneous lesions. A 63-year-old female with a 1-year history of a skin rash on her face visited the dermatology department of our hospital. The patient had received a dermal filler injection with unidentified gradients on the face of an unlicensed practitioner 20 years before. The lesions on the left cheek were tender, violaceous, coalescing, and annular. A violaceous round nodule with tenderness was observed on the left chin and glabella. She denied having any systemic complaints. The biopsy specimen showed diffuse interstitial CD68＋ histiocytic infiltration involving the reticular dermis around the degenerative collagen bundles. The patient was diagnosed with IGD. The patient was treated with systemic steroids and showed clinical improvement. Herein, we report a case of IGD after an unknown dermal filler injection, along with a literature review.
