title: [Cutaneous extension of parotid carcinoma].
abstract: BACKGROUND
  Telangiectatic cutaneous metastases are mostly associated with breast carcinomas. We report a case which was developed from a parotid tumour.
  
  
  METHODS
  A 63-year-old patient presented an erythematous, telangiectatic, rounded, cutaneous lesion of the cheek developed over a parotid tumour. Metastatic lymph nodes were observed in the drainage area of the tumour. Cutaneous histology revealed the presence of neoplastic cells in dermal vessels. After its surgical excision, histology of the parotid tumour showed an undifferentiated adenocarcinoma. Cutaneous lesions disappeared with chemotherapy.
  
  
  CONCLUSIONS
  Two similar cases of inflammatory and telangiectatic cutaneous metastases associated with parotid carcinomas were reported previously. This metastatic localization to the skin could be due to special anatomic conditions and perhaps to the similarity of some surface antigens between skin vessels and parotid carcinoma cells.
