Subcutaneous Panniculitis-Like T-Cell Lymphoma Presenting with Full Facial Edema and Hemophagocytic Syndrome.

A 42-year-old previously healthy woman presented with a 2-month history of recurrent fever and painful swelling on the left thigh. She was given a presumptive diagnosis of cellulitis and an antimicrobial. Because the response was not significant and fever remained moderate to high grade, with the appearance of gradually increasing periorbital edema (Figure 1), the diagnosis was reconsidered, and she was referred to a tertiary referral center for further study.
