title: Facial swelling: an atypical presentation of cutaneous lymphoma.
abstract: BACKGROUND
  Cutaneous lymphomas (primary and secondary lymphomas involving the skin) are a heterogeneous group with various clinical manifestations, histological features, and prognoses.
  
  
  METHODS
  We describe eight cases of cutaneous lymphoma presenting with facial swelling.
  
  
  RESULTS
  Our case series included three cases of primary cutaneous extranodal natural killer/T-cell lymphoma, one case of secondary cutaneous extranodal natural killer/T-cell lymphoma, one case of subcutaneous panniculitis-like T-cell lymphoma, one case of cutaneous CD4+ small/medium pleomorphic T-cell lymphoma, and two cases of peripheral T-cell lymphoma (unspecified).
  
  
  CONCLUSIONS
  This collection of cases and literature review emphasizes the need for clinical suspicion of cutaneous lymphoma in the differential diagnosis of patients with refractory facial swelling.
