<unk> s usually present as a smooth, flesh or yellow colored, slow-growing nodule or bump somewhere on the face or neck with typical development being 3–5 years. The most common location is the mouth (occurring in 74% of cases), however cases have been documented on the scalp, tongue, trunk, upper extremities, and genitals. Patients are more likely to be white, female, and middle aged or elderly, although cases have been documented in children. Although usually presenting with no visual or physical symptoms, some patients do experience numbness, paresthesia, burning, or tingling. This may be due to the invasive nature of<unk> s, which can burrow deep into underlying tissues and nerves in the face.<unk>  is very difficult to recognize and differentiate from other conditions. Specialists may suggest a series of tests including a biopsy, an MRI, or a CT scan. The average tumor size is less than 2 cm, however cases have been documented where tumor size exceeds 7.9 cm. While death is rare among<unk>  patients, it can occasionally metastasize to local lymph nodes. The 10 year overall survival rate is 86.4%, however this is exceedingly close to many 10 year survival rates of populations without<unk> s present.
