Neuroendocrine Tumors of the Female Reproductive Tract: A Literature Review

Neuroendocrine tumors of the female reproductive tract are a heterogeneous group of neoplasms that display various histologic findings and biologic behaviors. In this review, the classification and clinicopathologic characteristics of neuroendocrine tumors of the female reproductive tract are described. Differential diagnoses are discussed, especially for non-neuroendocrine tumors showing high-grade nuclei with neuroendocrine differentiation. This review also discusses recent advances in our pathogenetic understanding of these disorders.

Rabdomiosarcoma embrionario de cérvix uterino en mujer adulta / Embryonal rhabdomyosarcoma of uterine cervix in adult female

El rabdomiosarcoma (RMS) del tracto genital inferior es una patología maligna relativamente frecuente en la infancia aunque muy poco prevalente en la edad adulta. Tan solo suponen el 2-4 por ciento de todos los sarcomas de partes blandas. Se trata de una neoplasia derivada de células progenitoras de miocitos de músculo estriado en distinto grado de diferenciación. En un elevado número de casos, el cuadro se presenta como un pólipo endocervical de apariencia benigna, lo cual retrasa el diagnóstico. El correcto manejo del RMS de tracto genital es controvertido. Un esquema agresivo de tratamiento con cirugía, poliquimioterapia y radioterapia en pacientes seleccionadas, ha demostrado aumentar la supervivencia e incluso conseguir la curación en estadios precoces.

Rhabdomyosarcoma (RMS) of the lower genital tract is a common childhood malignancy but a rare tumor in female adults. It accounting for around 2-4 percent of soft-tissue sarcomas. It is a malignant neoplasm originating from myogenic progenitors cells that shows variable stages of skeletal muscle differentiation. In many cases, the tumor appears as a benign endocervical polyp and this delays the correct diagnosis. Optimal management of adult genital tract RMS is uncertain. Aggressive primary therapy with local excition, poliche-motherapy and radiotherapy in selected patients may result in prolonged survival and cure in early stages.
