Overall Learning Objectives: The physician or podiatrist participant will develop a rational approach to the evaluation and treatment of a variety of uncommon wounds and will have an increased awareness of the differential diagnosis of cutaneous wounds and the systemic diseases associated with these wounds.
Submissions: To submit a case for consideration in Diagnostic Dilemmas, e-mail or write to: Executive Editor, WOUNDS, 83 General Warren Blvd., Suite 100, Malvern, PA 19355, firstname.lastname@example.org
Completion Time: The estimated time to completion for this activity is 1 hour.
Target Audience: This CME/CPME activity is intended for dermatologists, surgeons, podiatrists, internists, and other physicians who treat wounds.
At the conclusion of this activity, the participant should be able to:
1. Discuss an interesting presentation of a leg ulcer.
2. Differentiate localized cutaneous amyloidosis from systemic amyloidosis.
3. Briefly discuss the difference between primary and secondary localized cutaneous amyloidosis.
4. Discuss the cutaneous amyloidoses with an emphasis on the more common macular and lichen forms.
5. Discuss management of this case of macular amyloidosis and leg ulcer.

A 62-year-old Hispanic woman presented with a history of intermittent ulcers on both lower extremities for two years prior to presentation. She complained of diffuse pruritus of her entire body, including itching in her legs, of which she admitted that she often scratched, causing small blisters filled with clear fluid. The pruritic blisters often progressed to painful ulceration, which had a history of slow healing and a minimal amount of drainage. Two-percent mupirocin ointment seemed to help heal her ulcers.
Her past medical history was significant for diabetes (20 years) for which she was taking oral hypoglycemic agents (glyburide and metformin). She had no history of deep venous thrombosis, cellulitis, surgery, or trauma to the legs. She denied arthritis, tobacco and alcohol use, hypertension, and cerebral or cardiovascular disease. Her past surgical history included appendectomy and hysterectomy. In addition to her oral hypoglycemic agents and occasional 2% Mupirocin ointment use, she was taking simvastatin. Her family history was negative for leg ulcers.
Physical examination revealed a petite Hispanic woman with diffusely xerotic skin.
