Presacral ganglioneuroma in an adult with 6-year follow-up without surgical treatment.

Ganglioneuroma is a rare tumour originating from neural crest cells, occurring mainly within children older than 7 years. It can be localised in pelvic; however, this localisation is extremely rare. This paper presents the case of a 39-year-old woman, at whom the pelvic localisation of the lesion and the unspecific symptoms associated with the digestive and genital tract impeded the recognition of the actual disease. The immensely slow growth of the tumour, combined with gradual fading of the symptoms, indicated its benign character. Only the CT-controlled biopsy enabled the recognition of the ganglioneuroma. Taking under consideration the histopathologic result and the cease of the symptoms, we decided to leave the patient under observation. After 6 years of observation, no progression signs have been recorded.
