<pre> | |||
Skin lesion, left elbow, excision: | |||
- Palisading granulomas with cores of necrobiotic collagen, and scant mucin | |||
consistent with granuloma annulare. | |||
COMMENT: | |||
An alcian-blue stain (pH 2.5) shows scant mucin. The granulomas are relatively deep; | |||
however, plasma cells are not apparent. The differential diagnosis is rheumatoid nodule. | |||
