Abstract: The classification of palmoplantar lesions resembling music box spines is confusing, and nearly all attempts at treatment have been futile. We present the case of a 62-year-old white man with symptomatic music box spine lesions on his palms and fingers composed of parakeratotic columns over a hypogranular epidermis. Lesions and symptoms disappeared after a short course of 6 percent salicylic acid gel applied under occlusion. We suggest a classification scheme for this and similar- appearing conditions under the title spiny keratoderma, based on their histologic pattern (parakeratotic or hyperkeratotic) and anatomical location (palmoplantar, diffuse, or associated with epidermal appendages).
