By Gary M. White, MD Multiple squamous cell carcinomas on the legs of an elderly woman

Squamous proliferations on the legs of older women has recently been described J Am Acad Dermatol. 2013 Sep;69(3):426-30. Patients are typically white, over 70 with much sun damage on the legs. Lesions resemble KAs, SCCs and/or prurigo nodularis.


Clinical

Multiple red, scaly, keratotic papules and nodules on the legs, particularly the shins, of an older white woman with much sun damage is characteristic [JAAD 2017;77;1126]. They may resemble eruptive keratoacanthomas. Crusting may develop from secondary infection and/or scratching.

Treatment

Patients should be encouraged not to scratch. Sun protection is in order to prevent further damage. A topical steroid may be helpful for the itch. Smaller papules may be frozen. Larger lesions may need curettage with electrodesication [Dermatologic Surgery 2015:41:750]. Acitretin 10-25 mg/kg/day and/or cyclosporine has been used with benefit.
