Follow-up
Further Outpatient Care
Patients with a waxing and waning course of Mucha-Habermann disease require follow-up monitoring and additional treatment depending on the severity of the disease.
Regarding the questionable potential for malignant transformation, some authors have suggested that follow-up biopsy should be performed on lesions that last longer than 1 year and are refractory to treatment.
Deterrence/Prevention
No preventive methods have been identified.
Complications
Ulceronecrotic pityriasis lichenoides et varioliformis acuta (PLEVA) can lead to scarring.
Prognosis
No clear consensus has been formed regarding duration of the disease, but most cases tend to resolve over time.
Miscellaneous
Medicolegal Pitfalls
A diagnosis of lymphomatoid papulosis should not be missed because of the theoretical possibility of subsequent development of a myeloproliferative disorder. Biopsies should be obtained to confirm a diagnosis of PLEVA.
Patients must be told that lesions may take time to resolve and that the duration of the disease cannot be predicted.
