Oral hyperpigmented lesions--a case study

An overweight woman, aged 58 years, presented for follow up of hypertension, diabetes and dyslipidaemia. She was noted to have hyperpigmented brown macules on the inner surface of the lower lip and buccal mucosa (Figure 1). She stated that she had first noticed these lesions when aged in her 40s. Her mother died at age 58 years from gastric cancer with extensive metastases, and her brother died at age 45 years from colon cancer with spread to the liver and lungs.
