Skin Cancer

3.9K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Changes in Skin Color: Clinical Perspectives

1.7K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Area of Science:

  • Neurology
  • Dermatology
  • Pediatrics
  • Oncology

Background:

  • Neurocutaneous melanosis (NCM) is a rare disorder involving melanin-producing cells in the skin and central nervous system.
  • It is a severe manifestation of congenital melanocytic nevus syndrome, associated with a risk of malignant melanoma.
  • NCM typically affects infants and young children, often presenting with a poor prognosis.

Purpose of the Study:

  • To report a rare case of spinal neurocutaneous melanosis in an 8-year-old male.
  • To discuss the clinical presentation of epilepsy and cognitive deficit in this context.
  • To contribute to the understanding of NCM presentation outside the typical pediatric age range.

Main Methods:

  • Case report of an 8-year-old male patient.
  • Clinical evaluation including neurological assessment and cognitive deficit evaluation.
  • Diagnostic workup for spinal neurocutaneous melanosis.

Main Results:

  • The patient presented with epilepsy and cognitive deficit.
  • Spinal neurocutaneous melanosis was identified as the underlying condition.
  • This presentation is atypical given the patient's age and the spinal localization.

Conclusions:

  • Neurocutaneous melanosis can manifest in older children with spinal involvement.
  • Epilepsy and cognitive deficits are significant clinical features associated with spinal NCM.
  • This case underscores the importance of considering NCM in the differential diagnosis of neurological symptoms, even in older pediatric patients.
