Diagnosis: Erysipelas of the face
A 65-year-old female presented with a 2-day history of a sharply demarcated bright red rash on her left cheek accompanied by fever and malaise. On examination, the patient exhibited classic signs of erysipelas, prompting further evaluation and management of this acute skin infection.
A 65-year-old female presented with a 2-day history of a sharply demarcated bright red rash on her left cheek, associated with fever and malaise. Examination revealed edema and warmth over the affected area, with notable tenderness upon palpation.Age: 65 years oldSex: FemaleDuration: 2 daysKey Complaint: Bright red facial rash with feverExam Findings: Edema, warmth, and tenderness localized to the left cheek
The rash began acutely following a recent dental procedure. The patient reported no history of trauma or insect bites. She has a past medical history of hypertension and diabetes mellitus, well-controlled with medication. There is no significant family history of skin infections. Socially, she lives alone and has limited mobility, increasing her risk of skin breakdown.Onset: Acute after dental procedureTriggers: Recent dental workPrior Treatments: None initiated prior to presentationPast Medical History: Hypertension, diabetes mellitusSocial History: Limited mobility, lives alone
Acute / First-Line ManagementInitiate oral antibiotics: Cephalexin 500 mg four times daily or Dicloxacillin 500 mg four times daily for 7-14 days.Consider Clindamycin 300 mg orally three times daily in cases of penicillin allergy.Supportive care including analgesics for pain management and hydration.Workup and Diagnostic ConfirmationClinical diagnosis based on presentation is usually sufficient; laboratory tests may include complete blood count (CBC) showing leukocytosis.Consider blood cultures if systemic symptoms are severe or if the patient is immunocompromised.Long-Term ManagementEducate the patient on skin care and hygiene to prevent future infections.Follow up within 1 week to assess response to treatment and adjust antibiotics if necessary.Consider prophylactic antibiotics in patients with recurrent episodes.
Cellulitis: Similar to erysipelas but lacks the well-defined borders and typically involves deeper layers of the skin.Contact Dermatitis: Presents with erythema and possible vesicles, usually associated with exposure to an irritant or allergen.Herpes Zoster: May present with unilateral facial rash, but vesicular lesions and dermatomal distribution aid in differentiation.Impetigo: Superficial bacterial skin infection characterized by crusted lesions, typically more widespread and not sharply demarcated.Stasis Dermatitis: Presents with erythema and scaling, typically in lower extremities, associated with venous insufficiency.Fungal Infections: Tinea faciei can mimic erysipelas but usually has scaling and is not associated with systemic symptoms.Drug Eruption: Presents with generalized rash and systemic symptoms; history of medication exposure is key for differentiation.Vasculitis: Rarely may present with facial erythema, often accompanied by systemic symptoms and specific laboratory findings.
High-Yield PearlsDemarcation: Erysipelas is characterized by a sharply demarcated border of the affected area, setting it apart from cellulitis.Fever: Systemic symptoms such as fever and chills are common and reflect the infectious nature of the condition.Antibiotic Choice: First-line treatment includes oral antibiotics such as cephalexin or dicloxacillin; clindamycin is an alternative for penicillin-allergic patients.Monitoring: Regular follow-up is essential to ensure resolution; lack of improvement may indicate treatment failure or complications.Prevention: Educating patients on skin care and hygiene can reduce recurrence, especially in those with risk factors.Early recognition and treatment of erysipelas are crucial to prevent complications and ensure rapid recovery.
