Benign mixed tumour of the skin (chondroid syringoma) is an uncommon skin adnexal tumour, usually presenting as a slow growing solitary painless nodule. The morphological appearances are similar to those of a pleomorphic adenoma of the salivary gland. Hair matrix and sebaceous differentiation can be seen in some lesions. Focal ossification is a rare finding. This report presents a case of a similar tumour arising in the cheek of a 43 year old white man, showing extensive ossification. Clinical, radiological, and pathological correlation and diagnosis proved to be difficult preoperatively. Only two cases of a benign mixed tumour with pronounced ossification have been reported so far, both in Japanese patients. This is the first reported case seen in a white man. Awareness of these lesions will avoid potential diagnostic pitfalls.

We describe an unusual variant of intradermal malignant melanoma without any junctional component. The lesion differed from other intradermal melanomas in that it was devoid of pigmentation and was composed of mainly spindle-shaped cells. Within the lesion, there were areas of pseudoglandular and myxoid changes resembling the rare myxoid melanoma. In addition to this, there were areas with an alveolar-like architecture containing nested groups of cells.
