“JUVENILE” XANTHOGRANULOMA IN A 77–YEAR‐OLD MAN

A 77-year-old white man presented with a 2-month history of nontender, nonpruritic, smooth, yellow-red papules. He stated that the first lesion appeared on his anterior left thigh, followed by several others on his lower extremities, abdomen, and back, as well as one on the right forearm; none developed on his face, neck, chest, irides, or mucous membranes. He further stated that three of the early lesions (all smaller than 3 mm) had regressed spontaneously in 2 to 3 weeks, whereas the others had grown quickly to their full size of 4 to 7 mm (Fig. 1). At the time we first saw him, he had a total of 12 papules. On physical examination, the mucocutaneous findings were as noted above, and one lesion was removed for histopathology. Family history was negative for xanthomatous lesions, hyperlipidemia, diabetes mellitus, cancer, and neurofibromatosis. Laboratory studies included complete blood count, chemistry panel, urinalysis, and lipid profile, all of which were normal. At his second visit, six papules were treated empirically: the one on the right anterior thigh was injected with 0.25 mL of triamcinolone acetate 40 mg/mL (10 mg total dose), five other lower extremity lesions were treated with a 10-second application of liquid nitrogen, using a cottontipped applicator. Three weeks later, the papule that had been injected showed no resolution, whereas those that had been treated by cryotherapy showed good-to-moderate regression; however, the patient had developed six new lesions, for a total of 18. Six papules were marked for test purposes and treated with liquid nitrogen for varying lengths of time. At follow-up 1 month later, the results were excellent (Fig. 2 and Table 1). All remaining lesions received further cryotherapy. The patient was quite satisfied with the treatment, and indicated that he would return if any new lesions occurred. Upon follow-up some months later, all existing lesions had flattened completely, and no new ones had appeared. Hematoxylin and eosin staining showed a diffuse dermal infiltrate, consisting mainly of histiocytes, many of them having foamy cytoplasm. Admixed with these were a large
