Paracanthosis is spelled pæɹəkænˈθoʊsɪs. The word is composed of the prefix "para-" meaning "near, beside, beyond" and the suffix "-canthosis" meaning "abnormal thickening of the skin or mucous membrane". The "c" in "canthosis" is pronounced as "k" because it follows "a", a consonantal sound, and is not preceded by a vowel. The stress in the word is on the second syllable, "can". Paracanthosis is a rare medical condition that affects the skin and is often a sign of an underlying disease.
Paracanthosis is a medical term that refers to the thickening and excessive growth of the skin on the palms and soles. This condition is characterized by the accumulation of keratin, a tough protein, which causes the affected areas to become hard, rough, and calloused.
Paracanthosis is commonly associated with conditions such as psoriasis, eczema, and dermatitis, where inflammation and irritation of the skin occur. It can also be caused by other factors including excessive friction or pressure on the palms and soles, genetic predisposition, or certain systemic diseases.
Symptoms of paracanthosis may include thickening and hardening of the skin, the development of corns or calluses, itchiness, and discomfort while walking or using the hands. In more severe cases, the thickening of the skin can lead to painful cracks or fissures.
Treatment for paracanthosis aims to reduce the thickness of the skin and alleviate symptoms. This may involve the use of topical creams or ointments that contain keratolytic agents to soften the skin and remove excess keratin. Additionally, moisturizers can be applied to prevent dryness and maintain skin integrity. In some cases, procedures like chemical peels or physical debridement may be performed to remove thickened layers of skin.
Proper foot and hand hygiene, avoiding excessive friction or pressure, and wearing appropriate footwear can help prevent paracanthosis. Consulting a healthcare professional is essential for an accurate diagnosis and personalized treatment plan.
