Documentation of Paronychia Exam Findings
Document paronychia by systematically describing the location, specific anatomical structures involved (proximal vs. lateral nail folds), presence or absence of key clinical features (erythema, edema, tenderness, purulent drainage, granulation tissue), and any associated nail plate abnormalities.
Essential Components to Document
Anatomical Location
- Specify which digit(s) are affected (e.g., "right thumb," "left great toe")
- Identify the nail fold involved: proximal, lateral (radial/ulnar or medial/lateral), or both
- Note if multiple digits are affected and document each separately
Primary Clinical Features
Acute vs. Chronic Classification 1:
- Acute paronychia: Symptoms present for <6 weeks, typically presents with sudden onset of pain, erythema, and swelling
- Chronic paronychia: Symptoms ≥6 weeks duration, characterized by persistent inflammation with loss of cuticle and nail fold retraction 2
Key Physical Findings to Document 3, 1:
- Erythema: Describe extent and intensity
- Edema/swelling: Note degree of nail fold enlargement
- Tenderness: Document on palpation
- Purulent drainage: If present, note color, consistency, and whether spontaneous or expressible
- Fluctuance: Indicates abscess formation requiring drainage
- Granulation tissue: Periungual pyogenic granulomas may develop 3
Associated Nail Changes
Document any secondary nail plate abnormalities 4, 5:
- Cuticle status: Present, absent, or detached (loss of cuticle is hallmark of chronic paronychia)
- Nail fold retraction or hypertrophy (chronic cases)
- Onycholysis: Separation of nail plate from nail bed
- Nail plate discoloration: Green (Pseudomonas), yellow-brown, or white
- Onychocryptosis (ingrown nail): Often coexists with paronychia 3
- Nail dystrophy: Thickening, ridging, or irregular growth
Additional Documentation Elements
- Duration of symptoms
- Occupational exposures (wet work, chemical irritants)
- Previous treatments attempted
- Pattern of involvement (single vs. multiple digits)
For Acute Paronychia 1:
- Precipitating trauma or manipulation
- Systemic signs (fever, lymphangitis, lymphadenopathy)
- Presence of abscess requiring drainage
Clinical Pitfalls to Avoid
- Don't assume infection: Chronic paronychia is primarily an inflammatory/irritant dermatitis, not infectious 2, 1. Secondary colonization with Candida or bacteria is common but not causative 5
- Consider drug-induced causes: In cancer patients on targeted therapies, paronychia is a common side effect requiring different management 3
- Rule out mimics: Psoriasis, lichen planus, and other inflammatory conditions can present similarly 6, 7
Sample Documentation Template
"Right index finger with erythema and edema of the lateral (radial) nail fold with tenderness to palpation. No purulent drainage or fluctuance appreciated. Cuticle intact. No nail plate abnormalities. Consistent with acute paronychia."
Or for chronic cases:
"Left thumb with chronic inflammation of proximal nail fold present for 3 months. Nail fold appears retracted with complete absence of cuticle. Mild erythema without active purulent drainage. Associated nail plate shows transverse ridging. No granulation tissue. Consistent with chronic paronychia."
