Hodgkin's disease mimicking suppurative lymphadenitis: a fine-needle aspiration report of five cases.

Spontaneous, suppurative-necrotizing changes associated with Hodgkin's disease (HD) are not infrequent. They are mostly observed in the nodular sclerosis variant of HD and can cause an erroneous histologic diagnosis of suppurative lymphadenitis. Few cytologic reports describing this presentation of HD are available. We describe 5 cases of HD that showed cytologic abscess-like smears dominated by a massive neutrophilic infiltrate and necrosis. Since therapy can induce similar changes, this study did not include patients with known HD. In 2 cases erroneously diagnosed as suppurative lymphadenitis, the presence of neoplastic cells was minimal and only detected after revision. A third case was misdiagnosed as abscessified metastasic carcinoma. Two cases were correctly identified as HD, although in one, the possibility of anaplastic large-cell lymphoma could not be ruled out. In conclusion, necrosis and massive neutrophilic infiltrates can occur spontaneously and can be prominent findings in smears from patients with HD, mainly the nodular sclerosis variant. The cytopathologist should always consider this possibility in the presence of an abscessified, suppurative, lymphadenitis-like aspirate. A detailed search for the characteristic neoplastic cells of HD is mandatory in these cases.
