Abstract

MOLGO N, Montserrat et al. Carcinoma espinocelular de la vulva: caso clínico. Rev. chil. obstet. ginecol. [online]. 2014, vol.79, n.5, pp.435-438. ISSN 0717-7526.  http://dx.doi.org/10.4067/S0717-75262014000500012.

Background: Squamous cell carcinoma (SCC) is a malignant epithelial neoplasm. SCC can be divided into 4 groups: non-melanoma skin cancer (NMSC), head and neck, esophageal and lung cancer. The risk for metastasis of SCC is 0.3-3.7%. Vulvar SCC is approximately 3-5% of all gynecological cancers. Case report: An 86-year old woman with a history of several years of genital pruritus and many consultations for this reason, prior treatments included valacyclovir for genital herpes; topical corticosteroids and tachrolymus for lichen sclerosus et atrophicus (LEA) with poor response. She presented with pruritus and new vulvar lesions. Physical examination showed two ulcerated nodules on the left periclitorid region and the introitus. The biopsy confirmed an infiltrating well-differentiated SCC. CT-scans discarded metastases. She received 7 weeks of radiotherapy. Due to persistence of the tumor the patient entered palliative care. Two years afterwards the patient is in good condition. Discussion: SCC represents 95% of vulvar malignancies. There are 2 types: SCC in young women, associated with high-risk human papilloma virus infection and SCC in elder women associated to the preexistence of LEA. 45-61% of vulvar SCC is associated in with preexisting LEA. Patients with LEA should be followed every 6 months. Conclusion: It is important to perform biopsies of vulvar lesions that have poor response to treatment, especially if they are associated with LEA.
