Purpose: Basosquamous carcinoma is a rare malignancy, with features of both basal cell carcinoma and squamous cell carcinoma. It is considered as aggressive tumor with a high risk of recurrence and metastases. Authors report a case of basosquamous cell carcinoma. Methods: A 72 year-old man, who had an erythematous ulcer on his left auricle, described a slow growing lesion, starting at the posterior surface of the superior helix with a steady increase in size during the past 10 years. At operation, auricular cartilage was grossly invaded by the tumor and was, therefore, amputated with tumor-free margins. Results: Histopathologic examination was revealed a basosquamous cell carcinoma. On positron emission tomography/computed tomography (PET/CT) and neck CT were negative for signs of further nodal involvement or metastases to other organs. At follow-up 6 months later, his wounds were noted to be well healed, with no evidence of local recurrence or identifiable metastases. Conclusion: Because basosquamous cell carcinoma has a significant potential to recur and metastasize, surgical excision for this type of carcinoma should be more extensive than that performed for conventional basal cell carcinoma or squamous cell carcinoma. In addition, regional lymph nodes should be monitored and close follow-up should be carried out.

Basal cell tumors from 53 dogs were examined histologically and classified as basal cell adenoma(n=44), granular basal cell adenoma(n=1), basal cell carcinoma(n=3), basosquamous cell adenoma(n=1), basosquamous carcinoma(n=4) on the basis of malignancy and squamous metaplasia. Female was twenty three and male was thirty. Affected dogs are usually 5.6 years and sex predilection have not been seen. None of tumor examined was metastasized into other organs. Distinct patterns identified in the basal cell adenoma are solid(n=15), cystic(n=13), adenoid(n=8), medusa(n=5) and ribbon(n=3). Solid basal cell adenoma is common type in benign basal cell adenoma. Only one neoplasm was granular basal cell adenoma which was characterized by eccentric nucleus and abundant granular cytoplasm. Basal cell carcinoma showed anaplastic appearance histologically and had atypical basaloid epithelial cells and multinucleated giant cells with moderate number of mitotic figures. Both basosquamous cell adenoma and carcinoma had squamous metaplasia.
