A 3-month-old infant experienced new-onset seizures, which resolved upon arrival. Brain magnetic resonance (MR) imaging was performed due to the presence of congenital skin lesions.
Area of Science:
- Pediatric Neurology
- Dermatology
- Medical Imaging
Background:
- A 3-month-old boy presented with a seizure history.
- No fever or family history of seizures was reported.
- Physical examination revealed no neurological abnormalities.
Observation:
- Multiple congenital skin lesions of varying sizes were noted on the scalp, trunk, and extremities.
- Laboratory tests were within normal limits.
- The patient's seizure subsided upon arrival at the institution.
Findings:
- Brain magnetic resonance (MR) imaging was performed to investigate the cause of the seizure.
- The presence of congenital skin lesions prompted further neurological investigation.
Implications:
- This case highlights the importance of considering neurological conditions in infants with congenital skin anomalies.
- Further investigation is warranted to determine the underlying cause and potential long-term implications.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
