Abstract
A case of cervical small cell carcinoma (SCC) with large cell neuroendocrine carcinoma (LCNC) differentiation is presented. A 35-year-old Taiwanese woman was diagnosed as having stage IIB bulky SCC confirmed by cervical biopsy and underwent induction combination chemoradiotherapy followed by hysterectomy. The pathology of the cervical tumor after the initial treatment showed the residual tumor to be LCNC instead of SCC. Histochemistry, immunohistochemistry, and electron microscopy demonstrated presence of neuroendocrine differentiation on both the biopsy and the surgical specimens. Following surgical resection a course of adjuvant chemotherapy and a local radiation boost were added. Despite complete local control, she developed brain metastasis 8 months later and vertebral spread soon thereafter. The pathology of the brain tumor showed pure SCC. The patient died 19 months after diagnosis and 13 months after completion of treatment. This case suggests that SCC with LCNC component has a similar clinical course as a pure SCC.
