Focal Cicatricial Alopecia (Congenital)

Common causes of congenital focal cicatricial alopecia are discussed below.

Temporal (Congenital) Triangular Alopecia

It presents as well-circumscribed triangular or ovoid patch of alopecia that involves the temporal region.[71] Vellus hair is present in the affected area. There is no effective treatment.

Aplasia Cutis Congenita

Aplasia cutis congenita constitutes a group of disorders that present at birth with eroded areas in the scalp or body with or without other developmental anomalies.[72,73] The scalp erosions are characterized by absence of a part of skin which heals spontaneously over a period of time and manifests as a patch of cicatricial alopecia.

Nevus Sebaceous

Nevus sebaceous of Jadassohn is a common clinical entity which belongs to the group of epidermal nevi, usually manifesting early in life in the form of an orange, waxy hairless circumscribed plaque most commonly localized on the head and neck area.[74] It may be part of epidermal nevus syndrome in association with other development anomalies. Excision is recommended in view of potential to develop cutaneous malignancies.

Keratosis Follicularis Spinulosa Decalvans

Inherited as X-linked disease, keratosis follicularis spinulosa decalvans is characterized by widespread follicular hyperkeratosis followed by atrophy, cicatricial alopecia of the scalp and photophobia. Topical and intra-lesional corticosteroids and oral retinoids have been used with usually unsatisfactory results.[75]
