Two cases of basosquamous cell carcinoma of the skin with lymph node, lung and bone metastases are reported. Metastases occurred 4 and 7 years after identification of the primary tumour. Both the primary and metastatic lesions had areas of typical basal cell carcinoma and squamous cell carcinoma and also intermediate carcinomatous tissue. In the bone metastasis of one case there were rudimentary hair follicles and areas of matrical differentiation. These cases further support the existence of basosquamous cell carcinoma and emphasize its metastatic potential.

Primary cutaneous CD30-positive large cell lymphoma is a recently described entity, recognized by immunohistochemical criteria. Spontaneous regression may occur and although relapses are frequent, most patients have a favourable prognosis. We describe a 83-year-old woman with a large ulcerated tumour on her right forearm, with 2 months evolution. Histological and immunohistochemical examination revealed a CD30-positive large cell lymphoma. Systemic involvement was not detected. The tumour regressed spontaneously. Cutaneous relapses occurred one year later, all with spontaneous regression. After a 2-year follow-up period, the patient is well, without concurrent extracutaneous disease. This case is in keeping with other reports of spontaneous regression and favourable outcome of this type of cutaneous lymphoma.
