Abstract
Background. With the resurgence of syphilis in the hiv era, a greater awareness of the clinicopathologic features of the disease is desirable. This report describes and correlates the clinical and histopathologic features of secondary syphilis seen at a teaching hospital in Delhi, India. Methods. Forty biopsies of mucocutaneous lesions from 31 consecutive patients with secondary syphilis, seen between September 1987 and January 1991, were studied and the histopathologic findings correlated with the clinical findings. Results. A spectrum of histopathologic changes ranging from a minimal infiltrate to granulomatous inflammation throughout the dermis was seen. The pattern of inflammation correlated well with the type of skin lesion, with macules showing the least and nodules the most prominent changes. The predominant cell type in the infiltrate was the mononuclear cell/lymphocyte. Plasma cells were seen infrequently. except in condylomata lata. Endothelial proliferation, the “classical” feature of the histopathology of syphilis was noted infrequently. Conclusions. The histologic manifestations of secondary syphilis appear to be as varied as the clinical ones. This calls for close interaction between the clinician and the pathologist to correlate the clinical, serologic, and histologic findings to establish the diagnosis of syphilis.
