SIGNS AND SYMPTOMS
  • Dysuria, hematuria
  • Poor urinary stream
  • Whitish, narrowed preputial opening of the foreskin
  • Edema, erythema, and tenderness of prepuce
  • Balanoposthitis
    (inflammation of the glans and foreskin)
  • Ballooning of foreskin on urination in severe cases
Physical-Exam

Exam should include an evaluation for potential complications:

  • Obstruction and vascular compromise of glans
  • Occur only in the most extreme cases
ESSENTIAL WORKUP
  • In the majority of cases, no workup is necessary.
  • In patients with severe stenosis, the complication of an
    obstructive uropathy
    may occur. This should be investigated by:
    • Evaluation of kidney function:
      • BUN and creatinine
    • Renal sonogram
  • Phimosis secondary to recurrent balanoposthitis should prompt a workup for
    diabetes mellitus
    :
    • Urinalysis, serum glucose, or glycosylated hemoglobin (Hgb A1C)
DIFFERENTIAL DIAGNOSIS
  • Preputial adhesions are normal in young children.
  • Balanoposthitis without phimosis
TREATMENT
PRE HOSPITAL
  • Pre-hospital personnel and family members should be instructed not to attempt retraction of the foreskin prior to medical evaluation.
  • Unwarranted attempts may traumatize a normal, nonretractable prepuce or convert the situation to a more emergent
    paraphimosis
    .
INITIAL STABILIZATION/THERAPY

None required in most cases

ED TREATMENT/PROCEDURES
  • Relieve obstructive uropathy, if present, with urethral catheterization or suprapubic aspiration.
  • If vascular flow to the glans is compromised, a dorsal slit must be made in the foreskin:
    • Performed after achieving adequate penile block (see Paraphimosis for more detailed description of procedure)
    • This is rarely necessary in phimosis.
  • Potent topical steroids for a multiweek course have been reported to successfully reduce phimosis:
    • Betamethasone dipropionate 0.05–0.1%: Apply to preputial orifice twice daily for 4–6 wk.
Pediatric Considerations

For foreskin incision, procedural sedation will likely be needed in place of penile block.

MEDICATION

Pain control as required

FOLLOW-UP
DISPOSITION
Admission Criteria
  • Obstructive uropathy
  • Severe balanoposthitis with ischemia or necrosis
Discharge Criteria
  • Ability to urinate
  • Adequate urologic follow-up
Issues for Referral

Urologic follow-up for response to steroid therapy, dilation of the preputial opening, operative repair, or elective circumcision as necessary

FOLLOW-UP RECOMMENDATIONS

Physiologic phimosis requires waiting for age-appropriate development and continued preputial hygiene.

PEARLS AND PITFALLS
  • Foreskin is normally nonretractable from the neonatal period to age 3 yr.
  • Do not forcibly retract foreskin especially in children 3–17 yr, as phimosis may still be physiologically normal.
  • Vascular compromise of the glans penis requires a dorsal slit to the foreskin to prevent necrosis.

PITYRIASIS ROSEA
Benjamin S. Heavrin
BASICS
DESCRIPTION
  • A self-limited skin exanthem of unknown origin primarily affecting children and young adults
  • Skin findings often begin with an isolated “herald patch,” an ovoid erythematous raised lesion seen along the trunk and extremities
  • A secondary eruption usually follows, where multiple smaller exanthems appear along the Langer lines of the trunk and proximal extremities in a symmetric “Christmas tree pattern”
  • Nearly 80% of symptoms resolve within 2 mo
ETIOLOGY
  • Unknown, although there is weak evidence for a viral etiology such as herpes 6 and 7
  • Many medications have been associated with a pityriasis-like reaction:
    • Barbiturates
    • Captopril
    • Clonidine
    • Gold
    • Isotretinoin
    • Metronidazole
    • Bismuth
    • Hepatitis B vaccine
    • Gleevec
    • Interferon
  • Eczema, asthma, and underlying malignancies may be weakly associated
DIAGNOSIS
SIGNS AND SYMPTOMS

Prodromal symptoms and characteristic skin findings are discussed below

History

Prodromal symptoms occur in 60–70% of patients:

  • Malaise
  • GI symptoms
  • Respiratory symptoms
Physical-Exam

Dermatologic findings

  • Herald patch:
    • Solitary, erythematous, slightly raised papule 2–10 cm in diameter
    • Seen in 50–90% of cases
  • Secondary eruption:
    • Widespread salmon-colored, elliptic, finely scaling papules
    • Usually appear symmetrically along Langer lines in a “Christmas tree” pattern
    • Generally follows herald patch by 7–14 days
    • Lesions are concentrated on the trunk and proximal extremities
    • Pruritus is common
  • Lesions concentrated on the face and distal extremities with minimal trunk involvement characterize
    inverse pityriasis
Pediatric Considerations
  • Inverse pityriasis, lesions on the face and distal extremities characterize
    inverse pityriasis
    and may be seen more often in pediatric populations
  • Rarely, pediatric presentations may have oral lesions, usually punctate hemorrhage and ulceration
ESSENTIAL WORKUP

Exclude other diagnoses, especially when a herald patch is not seen:

  • Secondary syphilis can have similar skin findings. Consider RPR in a patient with STI risk factors
  • KOH prep may diagnose tinea
DIAGNOSIS TESTS & NTERPRETATION
Lab

None required:

  • KOH and RPR if other diagnoses are considered
