Primary Cutaneous Large B-Cell Lymphoma, Leg Type, Localized on the Dorsum

Diffuse primary large B cell lymphoma of leg type presenting on the breast: a rare case of surgical excision

Primary breast lymphoma is a rare subtype of breast malignancy whose diagnosis relies on histopathological characteristics and a high index of suspicion in clinically unusual presentations of breast pathology. The authors report a rare case of diffuse primary large B cell lymphoma of leg type presenting as a single lesion confined to the breast. Unusually for this subtype of lymphoma, the lesion was surgically excised and the patient, to date, has made an uneventful recovery.

Primary cutaneous lymphomas: a reprisal

Primary cutaneous lymphomas (PCLs) are a group of lymphoid neoplasms provided with heterogeneous clinical, histological, immunohistochemical and molecular features. They can be classified in two groups: cutaneous T-cell lymphomas (CTCLs) and cutaneous B-cell lymphomas (CBCLs). Recent studies show an increase of the incidence of PCLs over the last three decades. Our aim is to evaluate the commonest types of PCL analysing the clinical characteristics, histology, phenotype, molecular biology, prognosis and therapy.
