title: [Intertoe space cutaneous epidermoid carcinoma].
abstract: BACKGROUND
  Localisation of epidermoid carcinoma in the intertoe space is very rare. We report a case occurring in a setting of chronic intertoe intertrigo.
  
  
  METHODS
  A 66 year-old woman presenting intertoe intertrigo for 30 years consulted for painful ulceration of the 3rd intertoe space of the left foot present for 4 years and refractory to antifungal treatment. The examination revealed ulceration with infiltrated edges occupying the entire 3rd intertoe space, with no satellite adenopathy. Histological examination of the skin biopsy sample revealed epidermoid carcinoma. Wide excision of the lesion was performed with a safety margin of 5 mm, with removal of the 3rd and 4th left toes. The outcome was favourable with no relapse after 12 months.
  
  
  CONCLUSIONS
  A single publication reported a series of 22 cases of intertoe epidermoid carcinoma in which the key aetiological feature of tumour was continual maceration. In this patient, maceration was maintained by a number of factors, including cultural factors: ritual ablutions performed 5 times daily, with no drying of the intertoe spaces, and domestic cleaning involving large quantities of water several times weekly.
