SAEM Clinical Images Series: Not Your Average Eczema

eczema

A 3-year-old male with a history of severe atopic dermatitis presented for facial rash and hand pain. Mom had been applying Aquaphor and Vaseline several times a day. On the day of presentation, he woke up with a new rash over his face and hands which prompted the ED visit. He is up to date on childhood immunizations and is not prescribed any oral medications.

 

Vitals: BP 103/61; HR 156; Temp 102.9°F; RR 30; SpO2 99%.

General: He appears in no acute distress, acting appropriately for age. Interacts and follows commands. Scratching himself all over.

Skin: Diffuse, itchy, dry skin throughout and findings noted in the attached images most notably erythematous pustules on the dorsal hands and peri-oral lesions in addition to punched-out ulcerations on the philtrum. Lesions are tender to palpation and spare mucous membranes and palms/soles. Nikolsky sign negative.

WBC: 12.96

Skin scraping: +VZV

This patient has Eczema herpeticum as demonstrated by multiple grouped pustules on an erythematous base.

Ophthalmology should be consulted to rule out ocular involvement most notably herpes zoster ophthalmicus.

Take-Home Points

  • Eczema herpeticum is typically caused by superinfection of Herpes Simplex Virus due to a diminished skin barrier from atopic dermatitis. It is commonly misdiagnosed as impetigo. Grouped vesicles/pustules on an erythematous base and tenderness to palpation should prompt the physician to suspect herpetic skin infection.
  • Eczema herpeticum may be potentially life-threatening if it has spread to multi-system involvement such as HSV keratitis or encephalitis.
  • Treatment includes acyclovir in addition to gram positive coverage such as TMP/SMX or cephalexin.

SAEM Clinical Images Series: Pediatric Forehead Swelling

puffy

A 12-year-old male with a history of autism spectrum disorder and chronic sinusitis presented for forehead swelling. His mother reported that she noticed progressive forehead swelling for about one month. She had followed up with the patient’s pediatrician and ENT and was given oral cephalexin and fluticasone nasal spray which did not make any changes in his symptoms. The patient denied any fevers or headaches.

Vitals: Temp 97.4°F; BP 100/58; HR 90; RR 18; SpO2 98%.

General: Patient is comfortable appearing, in no acute distress.

ENT: 3×3 cm area of fluctuance centrally located over the forehead with no drainage or surrounding erythema that is minimally tender to palpation. No nasal drainage.

Neuro: Intact with no deficits.

WBC: 14.35

ESR: 23 mm/h

CRP: 0.74 mg/dL

CT demonstrates osteomyelitis of the frontal bone with osseous destruction with a 5 cm bifrontal complex loculated anterior epidural abscess as well as a 3 cm midline frontal subgaleal extracranial scalp abscess.

Findings are consistent with Pott’s Puffy Tumor.

Take-Home Points

  • Pott’s puffy tumor is a rare, life-threatening complication of frontal sinusitis characterized by osteomyelitis of the frontal bone with associated subperiosteal abscess causing swelling and edema over the forehead and scalp. It can be found in all age groups but is most common in adolescents.
  • MRI brain with and without contrast is the preferred imaging modality due to increased sensitivity to detect early intracranial and osseous abnormalities.
  • Treatment is typically surgical intervention with at least 6 weeks of intravenous antibiotics. The infection is typically polymicrobial warranting gram-positive, gram-negative, and anaerobic antibiotic coverage.
