What is a common skin defect associated with Trisomy 13?

Trisomy 13, also known as Patau syndrome, is characterized by a variety of congenital anomalies, including skin defects. One common skin defect associated with this condition is scalp skin defects, which can manifest as a variety of abnormalities such as aplasia cutis congenita (absence of skin over the scalp) or abnormal hair patterns.

The presence of scalp skin defects is particularly relevant in the context of Trisomy 13, as it can coincide with other significant structural anomalies often seen in this genetic condition. Understanding these typical presentations can help healthcare providers recognize and manage the associated features of Trisomy 13 effectively.

While cleft lip, hypopigmentation, and melanocytic nevi may occur in various conditions and can be associated with different syndromes, they are not specifically recognized as common defects associated with Trisomy 13. This focus on scalp skin defects highlights the importance of assessing for specific physical anomalies that are characteristic of a particular genetic syndrome.
