Findings from the biopsy specimen demonstrated a circumscribed focus of lichenoid inflammation associated with atrophy of the stratum spinosum, hypogranulosis, and an overlying sharply circumscribed column of pale-staining orthokeratotic hyperkeratosis. The patient was treated with urea cream, 10%. She was subsequently lost to follow-up.
Flegel disease, or HLP, was first described by Flegel1 in 1958. It is a rare condition arising in the third or fourth decade of life, characterized by asymptomatic keratotic papules on the distal extremities, primarily the feet and legs. Typical lesions are skin-colored to reddish-brown papules surmounted by a horny adherent scale that when removed reveals a saucer-shaped base and pinpoint bleeding. Involvement of the palms, soles, and oral mucosa has been described.
