MANAGEMENT
OF SCARRING ALOPECIAS

Scarring alopecia is a leading symptom in the following diagnoses:
Chronic discoid lupus erythematodes (CDLE) of the scalp, lichen
planopilaris (LPP), postmenopausal frontal fibrosing alopecia
(PFFA), folliculitis decalvans (FD) and dissecting folliculitis
(DF).
The first step in the management of a scarring alopecia is
the correct diagnosis. Often a scalp biopsy is necessary.
If CDLE is a potential diagnosis, the biopsy should provide
a sample for direct immunofluorescence.
Therapies of T-cell mediated alopecias such as CDLE and LPP
are directed towards reduction of autoimmune and inflammatory
phenomena. This can be tried with class IV maximum strength
topical corticosteroids applied as solution or as creme
under occlusive dressing. Systemic corticosteroids are not
recommended for long term therapy. In CDLE, antimalarials
such as hydroxychroloquine sometimes can stop the disease
for the time they are being used. In addition, protection
from sunlight is essential. In LPP, acitretin may be helpful.
PFFA is thought to be a variant of LPP. Therefore, the progression
of the alopecia might respond to topical class IV coricosteroids
or acitretin.
In FD, staphylococcal infection is essential. Therefore, a
10-week antibiotic combination therapy consisting of rifampin
(300-0-300 mg/day) and clindamycin (300-0-300 mg/day) according
to Powell et al. (Br J Dermatol 140:328-333, 1999) is recommeded.
In DF, surgical debridement in combination with isotretinoin
has been helpful.
Therapeutic efficacy is difficult to measure due to the slow
natural course of these diseases. A successful therapy is
defined as stabilization of the disease. To monitor the slow
course of these diseases, we take standardized scalp photographs
every six months.
