Abstract: | Lupus panniculitis (LP), also referred to as lupus erythematosus profundus (LEP), is a chronic recurrent inflammation condition of the subcutaneous fat. It occurs in 1 to 3% of patients with systemic lupus erythematosus (SLE) and in 10% of patients with discoid lupus erythematosus (DLE), but can also occur as an entity of its own. Patients with lupus panniculitis usually present with persistent, often tender and painful skin lesions, or subcutaneous nodules, that range from 1 to 5 cm in diameter. The overlying skin may appear erythematous; lesions may become ulcerated, and heal with atrophy, skin depression, dimpling and scaring. Lesions tend to resolve spontaneously and may follow a chronic course of remission and exacerbation that persists for months to years.The imaging features of facial LP are extremely scarce in the literature. We present a case of facial lupus panniculitis and describe the associated characteristic ultrasound, CT, and MR imaging findings along with histopathologic correlation. |
