Primary cutaneous large B-cell lymphoma, leg type: Report of two cases and review of literature.

Primary cutaneous large B-cell lymphoma, leg type (PCLBCL-LT), is very rare neoplasm presenting on and confined to leg(s). PCLBCL-LT is distinguished from other type of primary cutaneous B-cell lymphoma (PCBCL) by its frequent relapses and poorer prognosis. We report, two cases of PCLBCL-LT, occurring in two younger patients compared to published cases in literature. Both the patients were treated with chemotherapy and local radiotherapy. During the 1-year follow-up period one patient presented with extracutaneous dissemination and succumbed. The other patient is symptom free and follow-up period was uneventful.
