Abstract
- We report here on a 63-year-old woman who presented with recurrent bruise-like infiltrative plaques on the left leg without systemic symptoms or laboratory abnormalities. The histopathologic findings showed an infiltration of panniculus by small to medium-sized atypical lymphocytes. But the prominent lymphoid atypia, fat necrosis, vascular thrombosis, erythrophagocytosis and striking dominance of CD8+ lymphocytes seen in subcutaneous panniculitis-like T-cell lymphoma (SPTCL) were not detected. The diagnosis of atypical lymphocytic lobular panniculitis (ALLP) was made based on these histopathologic and clinical features. The lesions responded well to systemic steroid treatment. But the CD4/CD8 ratio in the later lesion was more decreased than that of the initial lesion, and the patient is under clinical follow up.
