Testicular feminization syndrome (androgen insensitivity)

Area of Science:

• Pediatric Endocrinology
• Genetics
• Surgical Management

Background:

• Testicular feminization syndrome (TFS), also known as Androgen Insensitivity Syndrome (AIS), is a disorder of sex development.
• Individuals with TFS have 46,XY karyotype but present with female external genitalia due to impaired androgen receptor function.
• This condition is often diagnosed in childhood or adolescence due to associated complications.

Observation:

• Three pediatric cases of testicular feminization syndrome were identified over a four-year period.
• All three children presented with a large inguinal hernia, a common initial sign.
• Intraoperative frozen section confirmed the presence of testicular tissue within the hernia sac.

Findings:

• Surgical management included gonadectomy (removal of the testes) and herniorrhaphy (hernia repair).
• A staged approach is planned, with the second gonad to be removed after puberty.
• The study highlights the frequent association between TFS and inguinal hernias in pediatric patients.

Implications:

• Early diagnosis and surgical intervention are vital for managing TFS and its complications.
• This case series underscores the importance of considering TFS in children presenting with inguinal hernias.
• Understanding the genetics and presentation of TFS aids in optimizing patient care and long-term outcomes.
