Islet cell tumors in childhood

Area of Science:

• Pediatric Endocrinology
• Surgical Oncology
• Diagnostic Imaging

Background:

• Islet cell tumors (insulinomas) are rare in children.
• These tumors can cause severe hypoglycemia due to excess insulin production.
• Diagnosis and management in neonates present unique challenges.

Purpose of the Study:

• To review the literature on pediatric islet cell tumors.
• To present detailed cases of three affected children.
• To emphasize diagnostic and therapeutic strategies.

Main Methods:

• Literature review of 53 reported pediatric cases.
• Detailed clinical presentation of three specific cases.
• Focus on diagnostic angiography for tumor localization.

Main Results:

• Angiography is a key method for localizing pediatric insulinomas.
• Tumor localization can be particularly difficult in neonates.
• Surgical excision is the primary treatment for localized tumors.

Conclusions:

• Early and accurate localization is crucial for effective treatment of pediatric islet cell tumors.
• When localization is not feasible, pancreatectomy (subtotal or total) may be necessary.
• Further research into improved diagnostic techniques for neonatal cases is warranted.
