Lymphadenosis benigna cutis or cutaneous lymphoid hyperplasia or lymphocytoma cutis or pseudolymphoma is classified as one of the inflammatory disorder in which accumulation of lymphocytes on skin resemble, clinically and histologically as, cutaneous lymphomas. It manifests as asymptomatic, indolent, nodular lesions of different sizes varying between 2 and 5 cm, usually solitary, mainly on exposed areas of the body like face and neck. The presence of polymorphous cell infiltrates comprising of T and B lymphocytes, plasma cells, eosinophils, histiocytes and dendritic cells along with lack of atypical lymphocytes after incisional biopsy support diagnosis of pseudolymphoma. We report a 25 year old man who presented with bilateral postauricular swellings. The diagnosis was made as lymphocytoma cutis histologically and confirmed by immunohistochemistry. We report this case due to its distinct presentation and rarity of site and unusual size.
