Parathyroid carcinoma in a child: unusual presentation with seizures

Area of Science:

• Pediatric Endocrinology
• Oncology
• Nephrology

Background:

• Parathyroid carcinoma is an exceptionally rare endocrine malignancy, particularly in pediatric populations.
• The incidence of parathyroid carcinoma in individuals under 15 years old is exceedingly low, with limited documented cases.
• Understanding the clinical spectrum and presentation of pediatric parathyroid tumors is crucial for timely diagnosis and management.

Observation:

• The presented case involves a child diagnosed with parathyroid carcinoma, marking the second reported instance in this age group.
• The patient exhibited an atypical clinical presentation characterized by seizures.
• This unusual manifestation is hypothesized to be a consequence of severe hypercalcemia and/or a negative magnesium balance.

Findings:

• The diagnosis of parathyroid carcinoma was confirmed in a pediatric patient.
• Seizures were identified as a prominent and unusual presenting symptom.
• Biochemical analysis suggested a correlation between the seizures and metabolic disturbances, specifically hypercalcemia and hypomagnesemia.

Implications:

• This case underscores the importance of considering rare endocrine malignancies in the differential diagnosis of pediatric seizures with metabolic derangements.
• Further research into the pathophysiology of hypercalcemia and hypomagnesemia in pediatric parathyroid carcinoma is warranted.
• Highlighting this rare presentation can improve diagnostic awareness and clinical suspicion among healthcare providers managing pediatric endocrine and oncologic disorders.
