Summary
Liodermia is a term proposed by Finger in 1882 for a diffuse, widespread, confluent syphilitic papule that undergoes spontaneous regression in central parts without ulceration, accompanied by skin atrophy, and with serpiginous, scalloped borders of typical nodular syphilitic papules. It typically affects the upper torso and is treated with anti-syphilitic therapy.
Encyclopedia entry (1928–1936)
LIODERMIA SYPHILITICA (from Greek, leios- smooth and derma- skin), a term proposed by Finger (E. Finger; 1882) to denote a diffuse, widespread, confluent syphilitic papule that undergoes spontaneous regression in central parts without disintegration and ulceration, with atrophy of the skin, and along the edges forming a serpiginous, scalloped border of typical nodular syphilitic papules of the resolutory type, only scaling on the surface. The usual localization is the upper part of the trunk: chest and back. Histologically: typical syphilitic diffuse granuloma of the skin, undergoing connective tissue organization, with significant infiltrate around the vessels. Treatment is anti-syphilitic, as in all late syphilides.
