Skin Cancer01:30

Skin Cancer

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 Gene01:20

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,...

Pigmentation01:19

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...
Changes in Skin Color: Clinical Perspectives01:14

Changes in Skin Color: Clinical Perspectives

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...
Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
Somatic cells are...

Summary
This summary is machine-generated.

Pediatric melanoma, though rare, is rising. Early diagnosis of this skin cancer in children is crucial for better outcomes, with surgical excision as the primary treatment.

Area of Science:

  • Dermatology
  • Pediatric Oncology

Background:

  • Pediatric melanoma incidence is increasing.
  • Early diagnosis and prompt treatment significantly improve prognosis in children.
  • Clinicians should consider melanoma in pediatric patients presenting with pigmented lesions.

Purpose of the Study:

  • To highlight the importance of considering pediatric melanoma in differential diagnoses.
  • To outline risk factors associated with pediatric melanoma.
  • To describe current treatment modalities for pediatric melanoma.

Main Methods:

  • Literature review of pediatric melanoma cases and risk factors.
  • Analysis of diagnostic criteria for pigmented lesions in children.
  • Summary of established treatment protocols for pediatric melanoma.

Main Results:

  • Key risk factors for pediatric melanoma include xeroderma pigmentosum, giant congenital melanocytic nevi, and family history.
  • Surgical excision is the definitive treatment for pediatric melanoma.
  • Advanced cases may benefit from adjuvant therapies like chemotherapy, immunotherapy, or radiation.

Conclusions:

  • Increased vigilance for pediatric melanoma is warranted due to rising incidence.
  • Recognizing risk factors aids in early detection of pediatric melanoma.
  • Comprehensive treatment strategies, including surgery and adjuvant therapies, are essential for managing pediatric melanoma.
