Non-Melanoma Skin Cancers of Pinna: Retrospective Assesment of 51 Cases

Objective: The aim of this study was to retrospectively evaluate the demographic data, tumor types, relapse and recurrence rates of non-melanoma skin cancer cases of pinna. Methods: Pathological reports of our patients operated for non-melanoma skin cancer of head and neck region were scanned. Data of the patients with primary basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) of the pinna were retrospectively evaluated and age, gender, tumor location, tumor size, tumor type, tumor recurrence, lymph node involvement and metastasis of the patients were documented. Results: Out of the 535 patents who applied to our clinic for non-melanocytic skin cancer of head and neck region, 453 BCC and 179 SCC was excised. BCC/SCC ratio in the head and neck region was 3.5/1 tumors were resected from 51 patients who had pinna-located mass. BCC incidence in the pinna was 7%; SCC incidence was 14% in our patient population. Thirty three of the lesions (55.9%) were BCC and 26 (44.1%) were SCC. The BCC/SCC ratio in pinna was 1.3/1 and male/female ratio was determined as 16/1. Conclusion: We observed that non-melanoma skin cancer of pinna develops more frequently in male population and BCC is the most frequent tumor in this region.
