Small Cell Neuroendocrine Carcinoma of the Vagina: A Rare Presentation.

Primary small cell neuroendocrine carcinoma of the vagina is a very rare disease. We present a case study of a 52-year-old female who presented to the hospital with complaints of urinary dribbling, burning micturition, pain, and per vaginal bleeding for three to four months. A firm globular mass of approximately 5-6 cm was felt in the anterior vaginal wall per speculum examination. Diagnosis of small cell neuroendocrine carcinoma was made with tissue biopsy and immunohistochemistry. Diagnostic imaging (MRI, positron emission tomography (PET)-CT) plays a vital role in reaching the diagnosis and understanding the treatment response. The patient received six cycles of chemotherapy with cisplatin and etoposide and radiotherapy, achieving a complete response, with complete regression of the lesion. The patient had no sign of tumor recurrence and locoregional or distant metastases after six months of follow-up. Nowadays, there is no need for surgery in the treatment of vaginal small cell neuroendocrine carcinoma, rather radiotherapy and chemotherapy are the treatment of choice. We report a case of neuroendocrine cancer of the vagina treated at our institution.
