Diagnosis and Treatment of Descamative Lesions on Palms, Soles, and Face
Diagnostic Considerations
- The American Academy of Pediatrics suggests that fever is typically the first symptom of Hand, Foot, and Mouth Disease (HFMD), generally of low grade but can exceed 39°C (102.2°F), accompanied by malaise, sore throat, and irritability in young children 1
- The Centers for Disease Control and Prevention (CDC) notes that the exanthem begins as small pink macules that evolve into vesicular lesions, with a highly characteristic distribution on palms and soles 1
- The CDC also states that the vesicles subsequently rupture and cause desquamation, especially on palms and soles 1
- The World Health Organization (WHO) recommends considering potentially life-threatening infections, such as Rocky Mountain spotted fever, if the patient appears severely ill with high fever 2
Differential Diagnosis
- The Infectious Diseases Society of America (IDSA) suggests that Rocky Mountain spotted fever presents with a maculopapular rash that spreads to palms and soles 2-4 days after the onset of fever, with a mortality rate of 5-10% if left untreated 2
- The IDSA also notes that Ehrlichiosis presents with fever, headache, and rash involving palms/soles in 30% of adults and 60% of children, with a mortality rate of 3% 2
Treatment
- The American Academy of Pediatrics recommends supportive management, including fever control and adequate hydration, for HFMD 1
- The CDC states that the disease is self-limiting, with typical resolution in 7-10 days 1
- The WHO suggests that doxycycline should be administered immediately if Rocky Mountain spotted fever is suspected, without waiting for confirmation 2
- The British Association of Dermatologists recommends an expectant approach for warts in immunocompetent patients, as spontaneous clearance occurs in half of children within 1 year 3
Prevention of Common Pitfalls
- The American Academy of Pediatrics advises against confusing HFMD with Kawasaki disease: HFMD has discrete vesicles, not diffuse erythema 1
- The CDC warns against delaying treatment for suspected Rocky Mountain spotted fever, as this significantly increases mortality 2
- The WHO cautions against assuming that all palmoplantar eruptions are benign: consider infectious causes if there is high fever and toxic appearance 2
- The British Association of Dermatologists recommends against aggressive treatment of warts in immunocompetent children: spontaneous clearance is common 3
Hand and Foot Rashes in Children: Critical Diagnostic Considerations
Diagnostic Considerations and Medication Recommendations
- The Centers for Disease Control and Prevention recommends administering doxycycline immediately without waiting for confirmation if Rocky Mountain spotted fever is suspected, as mortality reaches 5-10% if untreated 4
- The Centers for Disease Control and Prevention suggests that meningococcal disease cannot be reliably distinguished from tick-borne rickettsial disease on clinical grounds alone, and some experts recommend intramuscular ceftriaxone pending blood cultures 4
- For a 1-year-old child with hand and foot rashes, the American Academy of Pediatrics recommends a dose of ibuprofen of 10 mg/kg/dose every 6-8 hours as needed, with a maximum of 40 mg/kg/day 4
