The objective of this studies is to review clinical and laboratory features of lupus panniculitis. The authors report 3 cases of lupus profundus from a group of 70 lupus erythematosus. In both cases the lupus panniculitis presented as subcutaneous infiltrated and indurated nodules. The diagnosis was confirmed on clinical, histological and therapeutic data. The evolution is slow and is characterised by regression of the inflammatory lesions with treatment by antimalarial drugs. The lupus panniculitis has generally a favorable prognosis.

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare type of non-Hodgkin lymphoma characterized by subcutaneous nodules, indurated plaques, erythema, and cellular infiltrates in the subcutaneous fat. Biopsies show neoplastic cells expressing cytotoxic T-cell markers and displaying moderate cytologic atypia while sparing the dermis and epidermis and showing variable degrees of necrosis, hemorrhage, and inflammatory changes. We describe a pediatric case of SPTCL in a 6-year-old boy, presenting with an unusual targetoid plaque and systemic symptoms, who showed significant improvement on systemic immunosuppressants without chemotherapy.
