Clinical and Histological Spectrum of Primary Cutaneous B-Cell Lymphoma in an Ethnically-Diverse Group of Patients: A Case Series

Primary cutaneous lymphomas, which are diagnosed with only skin involvement, can be of B or T cell origin. Due to their varied origin as well as their diverse presentations, these groups have been divided further into more descriptive and representative groups. The subtypes are primary cutaneous marginal zone lymphoma (PCMZL), primary cutaneous follicle center lymphoma (PCFCL), primary cutaneous diffuse large B cell lymphoma, leg type (PCDLBCL-LT) and intravascular large B-cell lymphoma. Here, we present the cases of three ethnically diverse patients with distinct clinical and histological forms of cutaneous B cell lymphoma.

Metastasis of Cutaneous B-Cell Lymphoma Affecting the Metatarsal Head: A Case Report

There are few reported cases of non-Hodgkin's lymphoma metastasis to bone in the lower extremities. The authors present a case of cutaneous B-cell lymphoma thought to be in remission, with metastasis to the first metatarsal head with involvement in the synovial tissue of the first metatarsophalangeal joint. Following excision of the lesion, no further treatment was determined to be necessary. The patient was to be observed for local recurrence.
