[Clinical and pathological analysis of rare nonepithelial vulvar tumors].

OBJECTIVE

To study the clinical presentation and pathological features of rare nonepithelial vulvar tumors.

METHODS

The clinical data of 42 patients with nonepithelial vulvar tumors who were operated on during 1986 to 2007 in Peking Union Medical College Hospital were analyzed.

RESULTS

The average age of 42 patients was 44.1 years. There were 32 cases (76%) with a vulvar mass. Twenty one of these 42 patients (50%) complained of associated symptoms of itch and pain. Surgical treatment was the chief treatment of nonepithelial vulvar tumors, which included local excision (40, 95%), simple vulvectomy (1, 2%) and radical vulvectomy (1, 2%). Among the pathological diagnoses after operation, the most common benign histological subtypes were hidradenoma and haemangioma, while the most common malignant histological subtypes were leiomyosarcoma and aggressive angiomyxoma.

CONCLUSIONS

Most of the nonepithelial vulvar tumors are mesenchymal tumors. The clinical presentation has no special characteristics. Diagnosis of nonepithelial vulvar tumors can be made based on histological inspection. Surgical treatment is the treatment of choice.
