title: Follicular B-cell pseudolymphoma.
abstract: A 60-year-old woman presented with a 3-week history of a pruritic papulo-nodular eruption on the face and trunk after a bee sting. Histological examination showed a predominantly lymphocytic infiltrate with follicular centres and tingible body macrophages. Immunohistochemically, positive staining for both kappa and lambda light chains was noted. The eruption settled with oral antihistamine and topical corticosteroid. These findings support the diagnosis of follicular B-cell pseudolymphoma.
