Abstract

Cutaneous leishmaniasis presents a spectrum of manifestations both clinically and histologically. Several previous studies have established the value of histological examination in the diagnosis of cutaneous leishmaniasis. Different reaction patterns have been reported. Forty cases of cutaneous leishmaniasis were studied in the Sultanate of Oman, with particular reference to the different histological features. Clinical features were correlated with the histological patterns. Four histological patterns were identified-1) diffuse macrophage infiltration without necrosis, 2) macrophage infiltration with necrosis. 3) early reactive granuloma and 4) established epitheloid granuloma. LD bodies were identified in 65% of cases. Epidermal features were nonspecific. Though the patterns could be correlated with the duration and the clinical type of lesion in a few cases, the correlation was not consistent.
