Summary
This review covers congenital melanocytic nevi (CMN), focusing on their histology and differentiation from other nevi and melanoma. It also discusses CMN-associated melanoma risks and mole changes.
Area of Science:
- Dermatology
- Pathology
- Oncology
Background:
- Congenital melanocytic nevi (CMN) are benign skin growths present at birth.
- Accurate histologic identification is crucial for patient management.
- Understanding CMN variants aids in distinguishing them from concerning lesions.
Purpose of the Study:
- To review the key histologic features of congenital melanocytic nevi (CMN).
- To discuss criteria differentiating CMN from atypical nevi and nevoid melanoma.
- To highlight diagnostic pitfalls and the risk of melanoma in CMN.
Main Methods:
- Review of existing literature on congenital melanocytic nevi (CMN) histology.
- Analysis of histopathologic criteria for CMN identification.
- Discussion of differential diagnoses and potential pitfalls.
Main Results:
- Detailed description of congenital melanocytic nevi (CMN) histologic variants.
- Criteria for differentiating CMN from atypical nevi and melanoma are presented.
- Common histologic pitfalls and melanoma risks associated with CMN are outlined.
Conclusions:
- Accurate histologic assessment is vital for diagnosing congenital melanocytic nevi (CMN).
- Awareness of diagnostic pitfalls improves CMN identification.
- Understanding melanoma risk in CMN informs clinical surveillance.

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.

01:19Pigmentation
4.9K
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...

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,...

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

01:14Changes in Skin Color: Clinical Perspectives
4.1K
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.
