Diagnosis: Acute paronychia
A 35-year-old woman presents with a painful, swollen area around her right index fingernail, which has developed over the past three days. She is a frequent hand-washer due to her occupation as a nurse, and she reports tenderness, redness, and purulent drainage. This case highlights the common presentation and management strategies for a prevalent nail unit infection.
A 35-year-old female nurse presents with a 3-day history of tenderness and swelling around the right index fingernail. On examination, there is significant erythema and edema surrounding the nail, with localized warmth and purulent drainage evident upon gentle pressure. The patient reports increased pain with movement of the finger.Localized erythema: Surrounding the nail plate, indicating inflammation.Swelling: Notable edema around the proximal and lateral nail folds.Pus formation: Purulent drainage can be expressed with gentle pressure.Tenderness: Pain on palpation of the affected area.Movement limitation: Painful range of motion of the affected digit.
The patient reports that the symptoms began suddenly three days ago after she noticed increased tenderness and swelling around her fingernail. She frequently washes her hands due to her nursing profession, often using alcohol-based sanitizers. There are no known prior episodes or treatments for similar symptoms. She denies any history of nail trauma or systemic symptoms. No significant past medical history or family history of dermatologic conditions is noted.Onset: Symptoms started acutely over three days.Triggers: Frequent hand washing and potential exposure to irritants.Prior treatments: No previous interventions for similar issues.Past medical history: Unremarkable; no chronic illnesses.Social history: Works as a nurse, frequently sanitizes hands.Family history: No significant history of skin conditions.
Acute / First-Line ManagementWarm compresses: Apply for 20 minutes, 3-4 times daily to reduce inflammation.Incision and drainage: If abscess is present, perform in-office drainage to facilitate resolution.Topical antibiotics: Consider mupirocin 2% ointment applied twice daily post-drainage.Oral antibiotics: If cellulitis is suspected or systemic symptoms present, initiate cephalexin 500 mg orally 4 times daily for 7-10 days.Workup and Diagnostic ConfirmationClinical diagnosis: Based on characteristic findings of inflammation and purulent drainage.Culture: If persistent or atypical, obtain a culture of the drainage to rule out fungal or atypical bacterial infections.Long-Term ManagementPreventive measures: Educate on proper hand hygiene and nail care; avoid excessive moisture.Follow-up: Schedule follow-up in 1 week to assess resolution of symptoms.Chronic cases: Consider referral to a dermatologist for persistent or recurrent paronychia.
Chronic paronychia: Characterized by prolonged inflammation and often associated with irritant exposure; presents with a more indolent course.Herpetic whitlow: Caused by HSV, presents with vesicular lesions on the fingertip, often more painful and with systemic symptoms.Onychomycosis: Fungal infection of the nail, typically presents with nail discoloration and thickening rather than acute inflammation.Felon: Infection of the fingertip pulp; presents with localized pain, swelling, and tenderness, often requiring surgical intervention.Traumatic nail injury: History of trauma may lead to subungual hematoma or infection, with a different treatment approach.Psoriasis: Can cause nail changes and paronychia-like symptoms, but systemic involvement and nail dystrophy are more common.Contact dermatitis: May mimic paronychia but usually involves more diffuse skin changes and pruritus.Bacterial nail infections: Other bacterial infections can present similarly but may vary in clinical course and management.
High-Yield PearlsHand hygiene: Frequent hand washing increases the risk of paronychia due to skin barrier disruption.Incision and drainage: Critical for management of abscess formation; often provides immediate relief.Antibiotic choice: Cephalexin is preferred for suspected bacterial infections, especially in cases with systemic involvement.Culture sensitivity: Important in atypical or recurrent cases to guide appropriate treatment.Prevention: Educating patients on nail care and minimizing irritant exposure can significantly reduce recurrence rates.Acute paronychia is a common condition that can be effectively managed with early intervention and education on preventive measures.
