Subtle Trichilemmal Carcinoma of Neck Initially Misdiagnosed as Benign Cyst and Ultimately Treated with Mohs Micrographic Surgery

Trichilemmal carcinoma (TC) is a rare malignant lesion from hair follicle cells, often misdiagnosed due to its non-specific appearance. This report details a 65-year-old man whose neck lesion was initially misdiagnosed as benign but later identified as TC. The study highlights the challenges in diagnosing TC and discusses various treatment options, ultimately recommending Mohs Micrographic Surgery (MMS) as the preferred treatment for this case.
