Ganglioneuromatosis intestinal difusa a lo largo del tubo digestivo.

BACKGROUND

Ganglioneuromas are histologically benign neoplasms derived from the sympathetic nervous system, whose occurrence in the gastrointestinal tract is rare and often syndromic. According to the injury pattern and extension, lesions are divided into polypoid ganglioneuroma, ganglioneuromatous polyposis, and diffuse ganglioneuromatosis. This work aimed to present the incidental post mortem finding of diffuse ganglioneuromatosis of the gastrointestinal tract in a patient without syndromic involvement.

CASE REPORT: We describe the case of a two-year-old female patient with surgically corrected type III tracheoesophageal atresia and fistulous recanalization, multiple episodes of aspiration pneumonia, and septic shock. During the last admission, she developed massive pulmonary hemorrhage and multi-organ failure. Post mortem histopathological study identified hypertrophy of the pylorus and enlarged enteric nerve trunks and plexuses with intermingled mature ganglion cells. We identified ganglioneuromatosis affecting all gastrointestinal tract segments with the predominance of the myenteric plexuses.

CONCLUSIONS

Intestinal ganglioneuromatosis is a rare disease with a spectrum of lesions ranging from isolated to syndromic with high morbidity and mortality. Therefore, it is necessary to know the condition, investigate systematically when it is suspected, and rely on genetic studies to confirm or rule out any syndromic association.
