title: A case of inguinal lymph node squamous cell carcinoma of unknown origin, accompanied with carcinoma in situ of cervix.
abstract: Metastatic Cancer of Unknown Primary Site (CUP) accounts for approximately 3-5% of all malignant neoplasms. CUP represents a heterogeneous group of metastatic tumors for which no primary site can be detected following a thorough medical history, careful clinical examination, and extensive diagnostic work-up. Several authors have reported poor prognosis of this malignancy, because there is no consensus on diagnostic guidelines and optimal therapy. Historically, chemotherapy has been the cornerstone of treatment for patients with CUP. We experienced a case of inguinal lymph node squamous cell carcinoma of unknown origin, accompanied with carcinoma in situ of the cervix. We report this case with a brief review of the literatures.
