Insights
A congenital umbilical lesion in an infant was diagnosed as an omphalomesenteric duct remnant. Histopathology confirmed ectopic intestinal mucosa, necessitating surgical evaluation for removal.
Area of Science:
- Dermatology
- Pediatric Surgery
- Histopathology
Background:
- Congenital umbilical lesions require careful evaluation to rule out underlying developmental abnormalities.
- Early identification of umbilical abnormalities is crucial for preventing potential complications.
Observation:
- A 6-month-old infant presented with a congenital, asymptomatic, violaceous polypoid papule on the umbilicus.
- The lesion was present since birth with no history of trauma or delivery complications.
Findings:
- Histopathological examination of the umbilical lesion revealed ectopic intestinal mucosa.
- The findings were consistent with an omphalomesenteric duct remnant.
Implications:
- Omphalomesenteric duct remnants require surgical consultation for complete evaluation and removal of ectopic tissue.
- Accurate histopathological diagnosis is essential for guiding appropriate pediatric surgical management.
Abstract:
A 6-month-old girl was presented to the clinic by her parents for evaluation of a skin lesion on the umbilicus present since birth (Figure). The infant's parents were concerned mainly because of its appearance, and they related that the child was essentially asymptomatic. There was no history of trauma to the area, and the parents denied any complications during delivery. The lesion appeared as a violaceous polypoid papule in the umbilical depression. A biopsy was performed and sent for histologic evaluation. The dermatopathology report revealed the presence of ectopic intestinal mucosa consistent with omphalomesenteric duct remnant. We fully discussed the situation with the parents and referred the child to a pediatric surgeon for complete evaluation and removal of any ectopic tissue.
