[Mixed plantar tumor clinically simulating eccrine poroma].
The case of a 39 years old female patient suffering from a painful, ulcerated nodule on the sole of her left foot for the last 15 months is presented. Clinically, for its localization and resemblance to a pyogenic granuloma, the lesion was considered to be an eccrine poroma. However its depth and tense, cystic feeling on palpation, were considered somewhat unusual. Microscopically the lesion was a "mixed tumour" of the salivary type with ductal differentiation and no cartilage formation. Seven other cases of plantar "mixed tumours" were gathered from the literature but neither ulceration nor poroma looking features were mentioned in any of them.
