(3) Histopathologically, in addition to folliculotropism, features such as epidermotropism, syringotropism, follicular mucinosis
, and granulomatous inflammation can be seen as per the spectrum of atypical cutaneous lesions.
(10,11) A few cases of ALHE/EH were found to have concurrent follicular mucinosis
. (15) However, this association is rather nonspecific, and a definitive association between ALHE/EH and mycosis fungoides has yet to be reported.
Results In our study, major causes of cicatricial alopecia were lichen planopilaris (27.5%), discoid lupus erythematosus (25%), pseudopelade of Brocq (20%), systemic lupus erythematosus (5%) followed by scleroderma, dermatomyositis, keratosis follicularis spinulosa decalvans, aplasia cutis, kerion, follicular mucinosis
, pemphigus, dissecting cellulitis of scalp/ pyogenic folliculitis and acne keloidalis nuchae in 2.5% cases each.
The histology of follicular mucinosis
differs from that of rosacea by the accumulation of mucin within empty spaces between follicular epithelial cells.
