Insights
Infantile myofibromatosis, a common childhood fibromatosis, can rarely present as a solitary jejunal tumor in newborns. This rare presentation is crucial for diagnosing neonatal intestinal obstruction.
Area of Science:
- Pediatric pathology
- Gastrointestinal surgery
- Neonatal medicine
Background:
- Infantile myofibromatosis (IM) is the most frequent fibromatosis in children.
- IM typically presents as solitary or multicentric lesions, affecting bone, soft tissues, or viscera.
- Solitary visceral IM is exceptionally rare.
Observation:
- A case of a newborn female infant with solitary jejunal infantile myofibromatosis is presented.
- This represents the sixth reported case of this rare condition in the medical literature.
- The patient presented with symptoms suggestive of intestinal obstruction.
Findings:
- The solitary jejunal tumor was identified as infantile myofibromatosis.
- The rarity of this specific presentation highlights diagnostic challenges.
- Literature review confirms the extreme infrequency of solitary visceral IM.
Implications:
- Solitary jejunal infantile myofibromatosis should be considered in the differential diagnosis of neonatal intestinal obstruction.
- Early recognition is vital for timely surgical intervention and improved patient outcomes.
- This case underscores the importance of comprehensive histopathological evaluation in neonatal surgical emergencies.
Abstract:
Infantile myofibromatosis is the most common form of fibromatosis in children. It can be solitary, mainly affecting the bone or soft tissues, or multicentric with the possibility of visceral involvement. Solitary forms of visceral localization are exceedingly rare. The authors report the observation of a newborn female infant, with solitary jejunal infantile myofibromatosis which after reviewing relevant litterature on the subject appears to be the sixth case of its kind. This form must be considered in the differential diagnosis of the neonatal intestinal obstruction.
