Inflammatory Myofibroblastic Tumour in Children: A Report of Two Cases and Review of Literature.

ABSTRACT: Inflammatory myofibroblastic tumour in paediatric patients present with a diagnostic dilemma because of its clinical, radiological and histopathological features overlapping with other mesenchymal tumours common in this age. Because of its rarity, the exact features are still unclear. Here, we are reporting clinical, radiological and histopathological appearances of two such cases. In both cases, the exact diagnosis was confirmed only after immunohistochemistry. There is a need for further detailed study to exactly determine the natural course and prognosis of these tumours.

Invasive investigation in cases of visceral AVM may be fatal: A rare case report.

INTRODUCTION AND IMPORTANCE: Visceral arteriovenous malformations (AVMs) are extremely rare with only a few cases described in the literature. We have encountered a mesenteric AVM in a 23-year-old girl. Considering the rarity of this entity and diagnostic dilemma, we herein describe a case of mesenteric AVM along with the review of literature. CASE PRESENTATION: A 23-year-old female presented with pain and lump in lower abdomen. During her workup to conclude a final diagnosis, Fine needle aspiration cytology (FNAC) was done. Post FNAC patient went into shock and immediately emergency laparotomy was done. The bleeding mass was resected along with involved gut and anastomosis was done. Histopathology suggested AVM. She was doing well at 2 months of follow up. CLINICAL DISCUSSION: AVM is the rare cause of ischaemic colitis. It can create a diagnostic dilemma with its unusual presentation and its rarity even for both radiologists and surgeons. Usually such malformation reported after trauma or any surgical intervention, but in our case there was no such history of trauma which makes this case more interesting. Invasive investigation is recommended in such condition but needs to be very cautious. As in this index case invasive procedure lead to severe bleeding. Although definitive treatment are embolization and surgery. CONCLUSION: Invasive procedure should be avoided in case of AVM. If angiography is not available its mandatory to keep operating room ready before any invasive procedure.
