Clinical and pathologic diagnosis and different diagnosis of syphilis cervical lymphadenitis.

PURPOSE: To study the clinical pathologic characteristics and differential diagnosis of syphilitic cervical lymphadenitis, and to improve the rate of its diagnosis and treatment.

METHODS

Retrospectively analyzed the clinical history, Trepone pallidum-ELISA (TP-ELISA), rapid plasma regain test (RPR) and routine pathological examination of the patient diagnosed as syphilis lymphadenitis. And review related literatures.

RESULTS

The main clinical presentation was multiple palpable cervical lymph nodes. The multiple nodes were hard, fixed, and the major diameter of the larger one was 2 cm. The main pathological changes included: the capsule was significantly thickened; reactive hyperplasia of lymphoid follicular with sky star phenomenon; occlusive endovasculitis; perivascular inflammation; the proliferation of epithelioid histiocytes can form granulomas with few multinucleated giant cells; few necrosis. TP-ELISA and RPR were positive.

CONCLUSIONS

The pathological changes of syphilitic lymphadenitis have a variety of performance with relatively specific and suggestive alterations which requires a combination of clinical history and laboratory test before the diagnosis, and the clinicians can reduce misdiagnosis and missed diagnosis of the disease by increasing vigilance of it.
