Resolution of granuloma annulare following treatment with bendamustine and rituximab in a patient with follicular lymphoma: a serendipitous finding.

Granuloma annulare is a benign inflammatory dermatosis. Cell-mediated immunity and delayed hypersensitivity are proposed pathogenic mechanisms. We report in this paper a case of generalized granuloma annulare that resolved after the patient was treated with rituximab and bendamustine for stage IV follicular lymphoma.
