A Rare Case of Paraneoplastic Syndrome of Inappropriate Secretion of Antidiuretic Hormone in Cervical Squamous Cell Carcinoma; A Case Report and Literature Review.

SIADH is more commonly associated with small cell lung cancer but has also been associated with other malignancies such as oropharyngeal, gastrointestinal, genitourinary, endocrine, lymphomas, and sarcomas. There have been few reports of small cell carcinoma of the cervix complicated by SIADH; however, not many cases are associated with squamous cell carcinoma of the cervix. We present a case of a patient with squamous cell carcinoma of the cervix with a paraneoplastic syndrome of inappropriate secretion of antidiuretic hormone. The pathophysiology, clinical picture, and treatment are also discussed.
