Classification Of Cicatricial Alopecias

Question 1

What is the proposed working classification of primary cicatricial alopecia by the North American Hair Research Society?

Answer 1

The classification includes:
* Lymphocytic
* Neutrophilic
* Mixed
* Nonspecific (end-stage)

This classification has minor modifications from the original proposal.

Question 2

List the conditions categorized under Lymphocytic primary cicatricial alopecia.

Answer 2

Conditions include:
* Lichen planopilaris
* Frontal fibrosing alopecia
* Graham Little syndrome
* Fibrosing alopecia in a pattern distribution (FAPD)
* Classic pseudopelade (pseudopelade of Broca)
* Central centrifugal cicatricial alopecia
* Chronic cutaneous lupus erythematosus (discoid lupus erythematosus)
* Alopecia mucinosa
* Keratosis follicularis spinulosa decalvans

Alopecia mucinosa is noted as a primary form not considered classic by some experts.

Question 3

What conditions fall under the Neutrophilic category of primary cicatricial alopecia?

Answer 3

Conditions include:
* Folliculitis decalvans
* Dissecting cellulitis (perifolliculitis capitis abscedens et suffodiens)

These conditions are characterized by neutrophilic inflammation.

Question 4

What is an example of a Mixed type primary cicatricial alopecia?

Answer 4

Examples include:
* Acne keloidalis
* Folliculitis (acne) necrotica
* Erosive pustular dermatosis

Mixed types exhibit features of more than one inflammatory process.

Question 5

What is classified as Nonspecific (end-stage) primary cicatricial alopecia?

Answer 5

Nonspecific (end-stage) primary cicatricial alopecia refers to cases that do not fit into the other specific categories of alopecia.

This classification signifies advanced stages of alopecia.

Question 6

True or False: Chronic cutaneous lupus erythematosus is included in the Lymphocytic category of primary cicatricial alopecia.

Answer 6

True

Also known as discoid lupus erythematosus.
