title: Extraosseous vulvar chondroma: a case report.
abstract: BACKGROUND
  Extraosseous chondromas are cartilaginous tissue tumors with a nodular appearance on the hands and feet. There are reports of these tumors occurring on the knee, neck, back, liver and testis and in the oral cavity. Occurrence in the pelvis is generally rare. The origin is metaplastic and may be mesenchymal or subcelomic. Treatment is by surgery and requires removing the tumor with a safety margin. Recurrences are infrequent, and distant metastasis has never been reported.
  
  
  METHODS
  An 11-year-old girl was referred for a painless solid tumor located on the mons pubis. Surgical removal of the tumor with a safety margin was performed. Macroscopically, the tumor was shiny when cut open and yellowish. Microscopic examination revealed a very distinct cartilage-forming tumor compatible with extraosseous chondroma. Two years after the operation, the patient had no recurrence.
  
  
  CONCLUSIONS
  Extraosseous chondroma is a rare benign tumor. Finding it in children is even less frequent, and localization in the vulvar region has never before been reported. This appears to be the first such report of this type of tumor in this region and age range.
