title: Malignant transformation of plantar ulcers in leprosy.
abstract: Malignant transformation of plantar ulcers in leprosy is not uncommon. The apparent rarity of these neoplasms could be because many observed cases are not reported. To determine the extent of the problem, 133 consecutive cases of plantar ulcers seen over two years were studied clinically as well as histologically. Plantar ulcers were more common in the distal third of foot (64.67%) but malignant transformation was seen more often in plantar ulcers of proximal third of foot (64.29%). Malignant transformation was more common in plantar ulcers of long duration. Histologically, most of the lesions were benign, being instances of pseudo-epitheliomatous hyperplasia (57.89%) or atypical pseudo-epitheliomatous hyperplasia (13.53%). However, squamous cell carcinoma was observed in 10.53% cases. Thus it may be that more cases with this complication will be detected if it is borne in mind that malignant change may be encountered in such ulcers.
