Background and Aim: Cicatricial alopecia is characterized
by permanent destruction of the pilosebaceous unit, leading to
irreversible hair loss, and has primary and secondary types. Primary type,
based on predominant inflammatory infiltration in histology, is divided to
neutrophilic, lymphocytic and mix types. Decalvans folliculitis, dissecting cellulitis and
acne keloidalis are 3 subtypes of neutrophilic group. In this study frequency
of each subtype and the distribution of age, gender and duration of disease
have been reviewed.
Methods: This retrospective study was performed on patients
with clinical diagnosis of cicatricial alopecia and histologic confirmation
referred to Razi hospital in Tehran in 2005-2009.
Results: Of 135 patients with mean (mean±SD) age of 32±10.6
years, 71.9% were male and 28.1% were female. The diagnoses included decalvans
folliulitis (72.6%) with mean age of 31.89 years, dissecting cellulitis (25.0%)
with mean age of 32.4 years and acne keloidalis (1.5%) with mean age of 52
years. The mean duration of disease was 4.2±3.9 years (4.08 years in male and
4.7 years in female). The mean duration of disease in decalvans folliulitis was
4.7, in dissecting cellulitis was 1.9 and in acne keloidalis was 17.5 years.
Conclusion:
Neutrophilic scarring alopecia is more common in men and in the third decade of
age and the most common type is decalvans folliulitis.
