Skin Cancer

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...

Pigmentation

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...

The Retinoblastoma Gene

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,...

Changes in Skin Color: Clinical Perspectives

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...

Summary

This summary is machine-generated.

Childhood cutaneous melanoma (CMC) diagnosis and treatment are challenging due to rarity. Histology and immunohistochemistry aid diagnosis, with pediatric patients showing better survival, but caution is advised.

Area of Science:

Pediatric Oncology
Dermatopathology
Cancer Diagnosis

Background:

Childhood cutaneous melanoma (CMC) is rare, with poorly understood prognostic factors and treatment effectiveness.
Lack of universally accepted diagnostic criteria complicates CMC research and clinical comparison.

Purpose of the Study:

To establish evidence-based diagnostic criteria for CMC.
To facilitate standardized interpretation and comparison of CMC cases across institutions.
To enable systematic reviews and meta-analyses for CMC.

Main Methods:

Comprehensive literature review of single-institution series since 1990.
Inclusion of cumulative experience with 137 pediatric melanoma cases (cutaneous and mucosal).
Analysis of clinical presentation, risk factors, histology, and immunohistochemistry for diagnosis and prognosis.

Main Results:

Histologic analysis combined with immunohistochemistry aids accurate CMC diagnosis.
Pediatric melanoma patients appear to have a higher survival rate than adults.
Metastasis and mortality occur in some children, especially if diagnosed post-puberty.

Conclusions:

Accurate diagnosis of pediatric melanoma is achievable through careful histologic and immunohistochemical evaluation.
While survival may be better in children, vigilance for metastasis is necessary.
Prudent CMC management should align with adult melanoma treatment principles pending further research.
