“…Simian creases were found in 26.1% of cases ( n = 21) in a 20‐year forensic autopsy study by Holz et al (). Moreover, simian creases in Trisomies 13 and 18 have been reported with incidences as high as 60% and 30%, respectively (Sarfraz, ). Dysplastic or aplastic ridges have also been noted in cases of Trisomy 18.…”

The creases of the palm have been of interest for clinicians, anthropologists, and palmists for hundreds of years, but the variations in them have only been studied during the past 50 years. The simian crease, aptly named for its resemblance to the palmar creases of nonhuman simian primates, has received recognition clinically and anthropologically owing to its abnormal appearance and confounding cytogenetic etiology. Given the rarity of these palmar creases but also their usefulness in diagnosing congenital disorders, discussion of cases of those disorders could provide clinicians with further helpful diagnostic knowledge. This review of the literature focuses on the history, embryology, genetic and hereditary origins, and clinical significance of simian creases for the benefit of the diagnosing clinician.

“…It is an autosomal dominant disorder caused by a point mutation of the SMARCAD1 helicase gene, resulting in restricted growth of the skin-specific protein [ 5 ]. Acquired causes of loss of fingerprints include dermatitis, primary hyperhidrosis, irritant contact dermatitis, atopic dermatitis, dyshidrotic eczema, psoriasis, mechanical abrasion, aging, trauma, burns, and medications [ 6 ].…”

Background: Capecitabine is a prodrug of 5-fluorouracil (5-FU) and is converted to 5-FU in tumor tissue. Its primary mechanism of action is the suppression of DNA synthesis via inhibition of thymidylate synthetase. It is mostly used for neoadjuvant chemoradiation, adjuvant chemotherapy for colorectal cancer, metastatic breast, and localized and metastatic gastric cancer, among others. Adverse effects of capecitabine include diarrhea, hand-foot syndrome (HFS), pancytopenia, stomatitis, increased bilirubin, nausea, vomiting, and very rarely adermatoglyphia. Dermatoglyphics refers to fingerprints. Adermatoglyphia refers to the loss of fingerprints.Case review summary: We report the case of a 62-year-old male patient known case of locally advanced colorectal cancer. He presented in the clinic with residual disease after initially being treated with local surgery and chemoradiation with 5-FU. Positron emission tomography (PET) scan done at the time of presentation showed locally advanced disease. He was managed with surgery followed by chemotherapy with oxaliplatin 130 mg/m 2 and capecitabine (Xeloda) 1500 mg twice a day for two weeks via three weekly cycles. Post cycle five, the patient complained of grade I HFS symptoms and inability to open a bank account due to loss of fingerprints. The patient was oblivious about this condition before that. After completing his adjuvant treatment that is six cycles of oxaliplatin and Xeloda, his symptoms of the HFS and loss of fingerprints, improved. Conclusion:As this case describes, adermatoglypia is a rare but noticeably side effect of capecitabine with a high chance of reversibility. Similar case reports have been reported with some normalization of fingerprints, after stopping treatment. Fingerprints have been used for centuries as means of identification in banks, aviation, immigration, computers, and mobile phones, amongst others. Awareness regarding the loss of fingerprints due to capecitabine is important for the patient and clinician, and alternative means of identification or other adaptive methods of recognition should be used for these patients.

All humans are born with unique physically identifi ed body characteristics to other persons which remains unchanged throughout life. These characteristics are taken into account by the emerging technology to get recognized from person to person. The technology used by the traditional human identifi cation system sometimes becomes ineffi cient when data or images received are not up to the acceptable quality mark or when a person has a face covered with mask-like during epidemic virus fi stula. In order to overcome such human recognition challenges, a Multi-biometric sustainable approach (D-nb) has been proposed using two uniquely identifi ed modalities like foot and iris. This approach shrewdly identifi es and makes the bodacious recognition among humans and suggests the sagacious result which is foremost better than the traditional biometric system.
