title: Cutaneous pseudolymphoma in association with molluscum contagiosum in an elderly patient.
abstract: BACKGROUND
  Molluscum contagiosum (MC) is a common cutaneous infection, which has been reported in association with cutaneous pseudolymphoma in few cases.
  
  
  METHODS
  A 72-year-old woman with a nodule arising on the external canthus was reviewed. The lesion was surgically removed, and the histopathological study demonstrated an epidermal invagination filled by molluscum bodies and a diffuse infiltrate comprising atypical lymphocytes.
  
  
  RESULTS
  Immunohistochemical stains disclosed predominance of T cells with positive CD30 labeling. Polymerase chain reaction failed to demonstrate clonal rearrangement of the T-cell receptor.
  
  
  CONCLUSIONS
  After ruling out systemic involvement, the patient was followed up for 2 years with no evidence of recurrence. We report this case to the best of our knowledge and discuss the literature about atypical clinical and histological presentations of MC.
