Metatypical Basal cell carcinomas: a successful surgical approach to two cases with different tumor locations

We present 2 rare cases of metatypical basal cell carcinoma - two 72-year-old male patients with ulcerative lesions localized either to the left forehead or the back. The biopsy revealed a metatypical basal cell carcinoma. The treatment consisted of a wide local elliptical excision with good cosmetic results. There was no sign of recurrence or metastasis during a 12 months follow-up period.Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) make up 95% of the most common types of cancer in the world - the non-melanoma skin cancer (NMSC). BCC is known for its potential to be locally invasive while SCC for its potential to metastasize in lymph nodes. The meta-typical basal cell carcinoma (MTBC) is a rare type of tumor which combines the clinical and histopathological features of both BCC and SCC with a 5% risk for the development of metastases. The gold standard for diagnosis lies in the histopathological verification of the lesional tissue. Clinical examinations alone are not enough.
