Overcoming Onychomycosis™ By Scott Davis If you want a natural and proven solution for onychomycosis, you should not look beyond Overcoming Onychomycosis. It is easy to follow and safe as well. You will not have to take drugs and chemicals. Yes, you will have to choose healthy foods to treat your nail fungus. You can notice the difference within a few days. Gradually, your nails will look and feel different. Also, you will not experience the same condition again!
Can a clinical examination alone diagnose onychomycosis?
A clinical examination alone can provide a strong indication of onychomycosis, but it is typically insufficient for a definitive diagnosis. Misdiagnosis is possible because other conditions can mimic fungal nail infections.
Clinical Features of Onychomycosis
During an examination, a healthcare provider looks for the following signs:
- Discoloration: Yellow, brown, or white patches on the nail.
- Thickening: Nail becomes brittle, hard, and thickened.
- Deformity: Changes in nail shape or crumbling edges.
- Subungual debris: Accumulation of material under the nail.
- Separation from the nail bed (onycholysis): Nail detaches partially or fully.
- Texture changes: Rough or ridged nail surface.
Limitations of Clinical Examination
- Subjectivity: Appearance alone can be misleading.
- Mimicking Conditions: Conditions such as psoriasis, eczema, lichen planus, trauma, and bacterial infections can look similar to onychomycosis.
- False Positives/Negatives: Visual inspection may miss mild cases or incorrectly attribute changes to fungal infection.
Diagnostic Confirmation
To ensure an accurate diagnosis, clinical examination is often combined with one or more of the following tests:
- KOH Preparation: Quick, initial confirmation by detecting fungal elements.
- Nail Culture: Identifies the specific fungal species.
- Histopathology (PAS Staining): Highly sensitive for detecting fungi in nail tissue.
- PCR (Molecular Testing): Rapid and precise but less commonly available.
When Clinical Examination May Suffice
In cases with classic symptoms and no history of trauma or other nail diseases, a clinical diagnosis might guide initial treatment. However, confirmatory testing is recommended before starting long-term antifungal therapies due to their side effects and cost.

The differential diagnosis for onychomycosis includes several conditions that can cause similar nail abnormalities, such as discoloration, thickening, and deformity. Accurate differentiation is essential for appropriate treatment.
Key Differential Diagnoses
- Nail Psoriasis
- Features: Pitting, thickening, yellow-brown discoloration (oil drop sign), onycholysis (detachment from the nail bed).
- Distinguishing Factor: Presence of psoriasis plaques on the skin or scalp.
- Traumatic Nail Dystrophy
- Features: Nail thickening, discoloration, ridging, or splitting.
- Distinguishing Factor: History of trauma or repetitive mechanical stress; usually localized to one nail.
- Lichen Planus
- Features: Nail ridging, splitting, and thinning; sometimes leads to complete nail loss (anonychia).
- Distinguishing Factor: Purple, itchy skin lesions and mucosal involvement.
- Eczema (Hand/Foot Dermatitis)
- Features: Rough, brittle, and thickened nails with discoloration.
- Distinguishing Factor: Coexisting eczematous skin lesions on hands or feet.
- Bacterial Paronychia (Chronic or Acute)
- Features: Redness, swelling, and pain around the nail fold, sometimes with greenish discoloration (Pseudomonas infection).
- Distinguishing Factor: Acute inflammation and absence of fungal elements.
- Yellow Nail Syndrome
- Features: Thick, yellow, slow-growing nails with onycholysis.
- Distinguishing Factor: Associated with respiratory disorders (like chronic bronchitis) or lymphedema.
- Alopecia Areata (Nail Involvement)
- Features: Nail pitting and roughness.
- Distinguishing Factor: Hair loss in distinct patches.
- Onychogryphosis
- Features: Thick, claw-like nail deformities.
- Distinguishing Factor: Often associated with aging and poor nail care.
- Congenital Nail Dystrophies
- Features: Thickened or malformed nails from birth.
- Distinguishing Factor: Lifelong history without fungal involvement.
- Melanonychia (Subungual Melanoma)
- Features: Dark longitudinal streaks under the nail.
- Distinguishing Factor: Irregular pigmentation and changes over time; requires biopsy for diagnosis.
- Pachyonychia Congenita (Rare Genetic Condition)
- Features: Thickened nails, painful calluses on palms and soles.
- Distinguishing Factor: Family history and early onset.
How to Differentiate
- Clinical History: Look for trauma, skin conditions, or family history.
- Physical Examination: Assess skin, nail beds, and surrounding tissue.
- Diagnostic Tests:
- KOH Test: Confirms fungal elements.
- Nail Culture: Identifies specific fungus.
- Histopathology (PAS Stain): Detects fungi and nail structure abnormalities.
- Biopsy: Helps rule out malignancies.
