Presentation of cases:

We present 2 cases of patients aged 4 and 9 years, who were admitted to an emergency room, with symptoms of chronic evolution characterized by a palpable abdominal mass, progressive weight loss associated with trichophagia-trichotillomania, with presumed diagnosis of gastric bezoar admission. The abdominal ultrasound in both reported an echorefringent image inside that produces an acoustic shadow, compatible with a probable trichobezoar, a diagnosis reinforced by contrast-enhanced computed tomography. Given the impossibility of endoscopic extraction due to the large size, it was decided to perform exploratory laparotomy, extracting the complete en-bloc mass through a gastrotomy in both cases. The patients presented a favorable evolution, receiving parenteral feeding for 5 days and then oral ingestion with good tolerance, being discharged from hospital on their 9th and 10th postoperative day with interdisciplinary follow-up and psychological support. There is a high suspicion of trichobezoar in the presence of trichotillomania, affective compromise, psychomotor retardation, intestinal symptoms and postsurgical neuropsychiatric management is essential in order to reduce the risk of recurrence.
