Intractable diarrhea of infancy with facial dysmorphism, trichorrhexis nodosa, and cirrhosis

Area of Science:

• Pediatric Gastroenterology
• Pediatric Dermatology
• Medical Genetics

Background:

• Intractable infant diarrhea is a known gastroenterological entity.
• Trichorrhexis nodosa, characterized by brittle hair, is a dermatological finding.
• Syndromic presentations often involve multiple organ systems.

Observation:

• A 3-year-old girl presented with severe intractable diarrhea, failure to thrive, and lifelong total parenteral nutrition (TPN).
• Physical examination revealed facial dysmorphism, hepatomegaly, mental retardation, and developmental delay.
• Microscopic examination of the hair confirmed trichorrhexis nodosa.

Findings:

• The patient's clinical presentation included severe intractable diarrhea, trichorrhexis nodosa, and liver cirrhosis.
• The constellation of symptoms suggests a potential link to the syndrome of intractable infant diarrhea.
• This case highlights the dermatological manifestation of a complex pediatric syndrome.

Implications:

• Dermatologists should consider trichorrhexis nodosa as a potential sign of underlying systemic syndromes.
• Increased awareness of the syndrome of intractable infant diarrhea among dermatologists is warranted.
• Further research may elucidate the genetic and pathophysiological basis of this rare condition.
