What type of skin rash is associated with cicatricial conditions and limb hypoplasia in TORCH infections?

In the context of TORCH infections, which comprise a group of infections that can cause serious congenital anomalies when transmitted from a mother to her baby during pregnancy, the varicella rash is indeed associated with cicatricial conditions and limb hypoplasia.

Varicella, or chickenpox, is a viral infection caused by the varicella-zoster virus (VZV). If a mother contracts varicella during the first trimester of pregnancy, the virus can lead to congenital varicella syndrome in the fetus. This syndrome is characterized by a classic triad of clinical findings: limb hypoplasia, cicatricial skin lesions (which are scarring rashes), and ocular defects. The scarring rash results in skin atrophy or scars that resemble the varicella lesions, which is why it is critical to understand the association of this rash with limb deformities and other severe congenital defects.

Other types of rashes mentioned do not have the same association with cicatricial changes or limb hypoplasia as seen in VARICELLA. Psoriasis, while a chronic skin condition, is not directly linked to congenital infections. Contact dermatitis is typically an irritation or allergic reaction and does not feature the scarring or limb deformities associated
