RESUMO
We report a case of a 10-year-old girl who, 4 years after a trauma to the neck, developed a soft tissue mass in the midline at the C5-6 level. The lesion was not attached to the bone and was composed of fibrocartilaginous tissue, similar to the nuchal fibrocartilaginous pseudotumor, a rare, recently reported condition that has been described in the medical literature in only 4 cases, all of them adults.

A case of glial tissue in a polypoid structure of the uterine cervix is presented; the presence of glial fibrillary acidic protein was demonstrated by immunoperoxidase, confirming the astrocytic nature of the tissue. The main hypotheses to explain this unusual finding are discussed.

We describe an 18-year-old woman with a mass in the region of the right ovary. The mass, which had a central cavity lined by endometrium and surrounded by smooth muscle, extraordinarily resembled a uterus. Review of the literature disclosed only one such case in which this change was considered to arise from endomyometriosis of the ovary, a phenomenon characterized by smooth-muscle metaplasia in a focus of endometriosis. Although this possibility is interesting and plausible, we believe that a congenital malformation, possibly caused by a defect in fusion of müllerian ducts, should strongly be considered in explaining the pathogenesis of this kind of lesion.
