Adenocarcinoma of the Cervix Associated with a Neuroendocrine Small Cell Carcinoma of the Cervix in the Spectrum of Muir-Torre Syndrome

Muir-Torre syndrome (MTS) is an autosomal genodermatosis that is diagnosed by the presence of at least one sebaceous gland tumor and at least one visceral malignancy. The most frequent visceral malignancies reported in literature are low-grade colon-rectal and genitourinary cancers, with prolonged survival. The authors report the case of a 52-year-old female, with a positive familial history for MTS, who developed a cutaneous sebaceous carcinoma, a synchronous colon-rectal adenocarcinoma, and a metachronous endocervical adenocarcinoma associated with a neuroendocrine small cell carcinoma of the cervix (SCNC), with lymph node metastasis. The rare occurrence in literature of the cervical SCNC and the rarest occurrence of a neuroendocrine carcinoma in the context of a MTS deviate from the usual and low-grade types of cancers normally described with MTS. It should be always appropriate to assess any symptoms that might reveal an underlying malignancy, although not within the spectrum of neoplasms most associated with this rare syndrome.
