Genital Herpes

Genital Herpes

Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...

Sex-linked Disorders

Sex-linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

External Female Genitals

External Female Genitals

The vulva encompasses the external structures of the female reproductive system. At the forefront is the monpubis, a cushion of fatty tissue atop the pubic bone. Once puberty sets in, this area typically grows hair. Extending from just behind the mons pubis are the labia majora (labia = 'lips'; majora = 'larger'), which are larger skin fs olds coated with hair. Nestled within are the labia minora (labia = 'lips'; minora = 'smaller'), which are thinner, more pigmented, and hairless. While the...

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...

Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...

Summary

This summary is machine-generated.

Atypical genital nevus, a rare melanocytic lesion, presents concerning histologic features but behaves benignly. Recognizing its unique characteristics is crucial to prevent misdiagnosis of melanoma in the sensitive genital area.

Area of Science:

Dermatopathology
Gynecologic Oncology

Background:

Atypical genital nevus is a rare melanocytic lesion.
It exhibits unique histologic features that can mimic melanoma.
It is poorly documented among nevi of special sites.

Purpose of the Study:

To describe the clinical and histologic characteristics of atypical genital nevus.
To differentiate atypical genital nevus from vulvar melanoma.

Main Methods:

Literature review of current findings.

Main Results:

Atypical genital nevus is most commonly observed in the vulva of premenopausal women.
Histologic features can be alarming, raising concern for melanoma.
Clinical behavior is generally benign, with rare local recurrence after incomplete excision.

Conclusions:

Accurate identification of atypical genital nevus is vital to avoid overdiagnosis of invasive melanoma.
Distinguishing it from melanoma prevents unnecessary aggressive treatments like wide excision or sentinel lymph node biopsy.
Awareness of this lesion's features is important due to its sensitive anatomic location.
