Primary cutaneous diffuse large B-cell lymphoma after total knee arthroplasty: a case study and a systematic review of its cutaneous manifestations and treatment options.

ABSTRACT:

Introduction

Primary cutaneous diffuse large B-cell lymphoma (PCDLBCL) after total knee arthroplasty (TKA) is rare.

Aim

The literature that analyses the cutaneous manifestations of PCDLBCL and assesses the effect and the outcome of treatment is scarce.

Material and methods

We described a case of PCDLBCL after TKA, whose cutaneous mass develops around surgical sites, mimicking a prosthetic joint infection. In addition, we conducted a systematic review of 29 reported cases with PCDLBCL. Primary endpoint for the review was main cutaneous manifestations of PCDLBCL. Secondary endpoint included treatment options of PCDLBCL and optimal therapeutic method.

Results

We found that the main cutaneous manifestations include infiltrative cutaneous lesions such as macules, papules or nodules, some of them presented as ulcerations or formation of vesicles, subcutaneous nodules or both. The treatment options include excision, radiotherapy, chemotherapy, and even "watchful waiting" as spontaneous regression was noted in some cases. Systemic chemotherapy is the most frequent initial treatment approach chosen, of which rituximab is often combined with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy and patients who received systemic rituximab tend to have a better overall survival (OS) time than those who did not.

Conclusions

PCDLBCL is a rare disease after TKA, however, an early recognition and distinguishing from infection is still needed. Patients with PCDLBCL may profit from rituximab-based chemotherapy, increasing the survival rate, despite the high relapse rate and limited OS time in some cases.
