Skin Diseases and Disorders

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

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...

Summary

Dermoscopy effectively aids in diagnosing pityriasis versicolor (PV), a common fungal skin infection, by revealing specific visual patterns. This non-invasive method can serve as a valuable alternative or supplement to traditional potassium hydroxide (KOH) mounts.

Area of Science:

Dermatology
Mycology
Medical Diagnostics

Background:

Pityriasis versicolor (PV) is a superficial fungal infection caused by Malassezia species, leading to skin discoloration and altered pigmentation.
Diagnosis is typically clinical, but dermoscopy offers an alternative for ambiguous cases when potassium hydroxide (KOH) mounts are unavailable.

Purpose of the Study:

To evaluate clinical and dermoscopic patterns in pityriasis versicolor.
To correlate these patterns with risk factors and fungal culture results.

Main Methods:

A 12-month cross-sectional observational study involved 115 patients with clinically diagnosed PV confirmed by KOH mount.
Dermoscopy was performed, followed by scale scraping for fungal culture on specialized media.
Results were analyzed after a 3-week incubation period.

Main Results:

Clinical evaluation revealed 79 achromic and 36 chromic lesions.
Dermoscopy showed fine scaling (88.7%) and non-uniform pigmentation in all patients.
Novel findings included 'barbed wire fence,' 'fluffy cotton ball,' and 'sprinkled pepper' appearances.
Fungal culture yielded growth in 51 (44.3%) cases, with Malassezia furfur being the most common isolate (18 patients).

Conclusions:

Dermoscopy is a valuable non-invasive diagnostic tool for PV, revealing characteristic features like scaling, pigment alteration, and perifollicular involvement.
It can be used as an adjunct or substitute for KOH mounts in diagnosing doubtful PV cases.
