The present case describes a rare and large size of giant keratoacanthoma (KA) of pinna.
Background
Keratoacanthoma is a fast growing benign cutaneous tumor resembling closely to well-differentiated squamous cell carcinoma (SCC) on clinical and histopathological examination (HPE).
Case report
A 70-year-old male presented with a rapidly growing mass on the left ear for 9 months. Tumor was excised and sent for HPE, which revealed well-differentiated SCC with focal features of a KA.
Clinical significance
Differentiation of KA from SCC has been a major challenge for dermatosurgeons, especially at setups with unavailability of molecular studies. So, if the tumor is giant, nonregressing in size especially on sun-exposed sites in an elderly patient, always think of SCC and treat it by surgical excision rather than watching for a spontaneous resolution.
