Abstract
Introduction Adermatoglyphia is defined as the medical condition clinically diagnosed to those who have a congenital or acquired loss of the epidermal ridges on the fingertips, commonly known as fingerprints. Capecitabine, a fluoropyrimidine, is the treatment of choice in a myriad of tumors and has occasionally been reported to cause adermatoglyphia as a secondary effect upon its use. Case Report A 52-year-old female patient, diagnosed with stage IV metastatic left breast cancer with extension to bone in late 2011 reported upon biopsy a hormone receptor positive Her2 negative ductal carcinoma. After initial treatment with a combined radiotherapy and chemotherapy palliative treatment, hepatic and lung metastasis progression obliged capecitabine oral intake. In 2018, after two years on the fluoropyrimidine (capecitabine), the patient reported adermatoglyphia. Management & Outcome The patient opted to continue taking the medication, since such treatment was working with no other meaningful side effects. Her last work-up studies continue to show complete lung and liver response with stable bone disease. Discussion Capecitabine is a common drug in the therapy against metastatic breast cancer due to its manageable safety profile. Hand-foot syndrome is a frequent side effect caused by this drug, with dosage adjustment recommended with progression of symptoms. Recent publications have reported adermatoglyphia as a rare side effect of capecitabine use. Upon further examination through dermatoscopy and biopsy, the patient was evidenced to have lost the epidermal ridges that form fingerprints. A score of 9 on the Naranjo scale confirmed to be a consequence of the administration of capecitabine.
