Which condition can lead to the complete loss of fingerprints?

Leprosy, caused by the bacterium Mycobacterium leprae, can indeed lead to a loss of fingerprints due to its effects on the skin and peripheral nerves. One of the hallmark manifestations of leprosy is significant skin lesions and damage, particularly affecting the extremities. As the disease progresses, it can cause nerve damage leading to loss of sensation in fingers and toes, along with changes in the skin texture that can result in the eventual atrophy or alteration of the dermal papillae, which are essential for the formation of fingerprints.

This alteration in skin structure can lead to a smoothing out or complete loss of the unique ridge patterns that characterize a person's fingerprints. The condition is particularly relevant in forensic medicine because fingerprint identification is a crucial method for establishing identity, and any factor that alters this can be significant in legal contexts.

The other conditions listed—Rickets, Acromegaly, and Celiac Disease—do not typically result in the complete loss of fingerprints. Rickets primarily affects bone development and does not have direct effects on the skin, Acromegaly involves the overproduction of growth hormone, leading to enlargement of bones and soft tissues without specifically causing loss of skin texture or fingerprints, and Celiac Disease primarily affects
