Skin Cancer01:30

Skin Cancer

6.6K
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...

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

322
In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Pharmacokinetics in Pediatric Patients: Drug Excretion

369
In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Pharmacokinetics in Pediatric Patients: Drug Distribution

443
Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

Summary
This summary is machine-generated.

Pediatric melanoma is rare in children under 10, with mimics like Spitz nevi being more common. Melanoma in older children and adolescents requires careful diagnosis, distinguishing it from mimics to avoid misdiagnosis.

Area of Science:

  • Dermatology
  • Pediatric Oncology
  • Pathology

Background:

  • Cutaneous melanoma is rare in children under 10, with Spitz nevi and congenital melanocytic nevi more frequent.
  • Melanoma arising in congenital melanocytic nevi is uncommon but can be aggressive.
  • Spitzoid lesions are diagnostically challenging but rarely cause mortality in young children.

Purpose of the Study:

  • To differentiate between melanoma and its mimics in pediatric patients.
  • To understand the behavior of pediatric melanomas, which can differ from adult types.
  • To highlight diagnostic challenges in older children and adolescents.

Main Methods:

  • Review of pediatric skin lesions.
  • Histopathological analysis of melanocytic lesions.
  • Clinical and pathological correlation.

Main Results:

  • Melanoma mimics are more common than true melanoma in children under 10.
  • Melanoma in congenital melanocytic nevi can exhibit aggressive behavior.
  • Spitzoid morphology presents diagnostic challenges, with risks of over- and under-diagnosis in older children.

Conclusions:

  • Accurate diagnosis of pediatric melanoma is crucial, especially in differentiating from mimics.
  • Biologically distinct pediatric melanomas require specific management considerations.
  • Vigilance is needed for spitzoid lesions in adolescents to ensure correct diagnosis and treatment.
