RESUMEN
Leiomyoma of the nipple and areola is a rare subtype of genital leiomyoma. The etiology of the tumor is not well understood. However, sex hormones like estrogen and progesterone have been implicated in the tumorigenesis. Hereby, we report a 47-year-old man with an estrogen receptor positive, progesterone receptor negative, leiomyoma of the areola.

Ependymomas, the common glial tumors of the spinal cord, occur occasionally outside the central nervous system and are called extraspinal ependymomas (ESE). ESE, which are clinically confused with other sacrococcygeal tumors, are rarely seen and found primarily in the sacrococcygeal region during childhood. We report a case of a seven-year-old boy presenting with a midline mass (6 cm diameter) over his coccyx. The solid mass was diagnosed as maxillopapillary type of ependymoma. Clinical and histopathological features of the case are described and literature reviewed.
