Studysummary This case study highlights congenital atrichia with papular lesions as a cause of total body hair loss, characterized by the absence of hair follicles and the presence of skin-colored papules. Our plain-language summary of this paper — not a Tressless recommendation.
Congenital atrichia with papular lesions (APL) was identified as a rare cause of irreversible childhood alopecia in a 9-year-old boy who exhibited sparse body hair and a history of hair loss shortly after birth. The presence of multiple skin-colored papules on the scalp and biopsy results showing keratinous cysts and absence of hair follicles confirmed the diagnosis. Vitamin D-dependent rickets was ruled out, emphasizing congenital APL as a distinct cause of total alopecia.
