Neoplasms Of The Nailbed

	Neoplasms Of The Nailbed Neoplasms of the nailbed may often present with paronychia, ingrown nail, onycholysis Onycholysis is a common medical condition characterized by the painless detachment of the nail from the nail bed, usually starting at the tip and/or sides. On the hands, it occurs particularly on the ring finger but can occur on any of the fingern ..., pyogenic granuloma, nail-plate dystrophy, longitudinal erythronychia, bleeding, and discolorations.James, William; Berger, Timothy; Elston, Dirk (2005). ''Andrews' Diseases of the Skin: Clinical Dermatology''. (10th ed.). Saunders. . There are various benign and malignant neoplasms that may occur in or overlying the nail matrix and in the nailbed, and symptoms may include pain, itching, and throbbing. Benign tumors of the nails include verruca, pyogenic granuloma, fibromas, nevus cell nevi, myxoid cysts, angiofibromas (Koenen tumors), and epidermoid cysts. Squamous cell carcinoma of the nailbed is uncommon, and often mistaken for a pyogenic granul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Paronychia Paronychia is an inflammation of the skin around the nail, which can occur suddenly, when it is usually due to the bacterium '' Staphylococcus aureus'', or gradually when it is commonly caused by the fungus ''Candida albicans''. The term is from el, παρωνυχία from ''para'' 'around', ''onyx'' 'nail', and the abstract noun suffix '' -ia''. Risk factors include repeatedly washing hands and trauma to the cuticle such as may occur from repeated nail biting or hangnails. Treatment includes antibiotics and antifungals, and if pus is present, the consideration of incision and drainage. Paronychia is commonly misapplied as a synonym for herpetic whitlow or felon. Definition and etymology Paronychia is an inflammation of the skin around the nail, which can occur suddenly (acute), when it is usually due to the bacterium ''Staphylococcus aureus'', or gradually (chronic) when it is commonly caused by ''Candida albicans''.

picture info	Ingrown Nail An ingrown nail, also known as onychocryptosis from el, ὄνυξ () 'nail' and () 'hidden', is a common form of nail disease. It is an often painful condition in which the nail grows so that it cuts into one or both sides of the paronychium or nail bed. While ingrown nails can occur in the nails of both the hands and the feet, they occur most commonly with the toenails (as opposed to fingernails), and for the most part are only problematic and painful on the big toe. A common conception is that the nail enters into the paronychium, but an "ingrown toenail" can simply be overgrown toe skin. The condition starts first from a microbial inflammation of the paronychium, and then a granuloma, which results in a nail buried inside of the granuloma. A true ''ingrown toenail'' is caused by actual penetration of flesh by a sliver of toenail. Signs and symptoms Symptoms of an ingrown nail include pain along the margins of the nail (caused by hypergranulation that occurs around ...

	Onycholysis Onycholysis is a common medical condition characterized by the painless detachment of the nail from the nail bed, usually starting at the tip and/or sides. On the hands, it occurs particularly on the ring finger but can occur on any of the fingernails. It may also happen to toenails. Onycholysis can occur in many conditions, including psoriasis. In thyrotoxicosis, it is thought to be due to sympathetic overactivity. It may also be seen in infections or trauma. Causes * Unknown * Trauma, excessive manicuring * Infection: especially fungal * Skin disease: psoriasis, dermatitis * Impaired peripheral circulation, e.g. Raynaud's syndrome * Systemic disease: hyperthyroidism, hypothyroidism, reactive arthritis, porphyria cutanea tarda * Reaction to detergents (e.g. washing dishes with bare hands, using detergent-based shampoos or soaps). * Patients with hepatocellular dysfunction may develop hair-thinning or hair loss and nail changes such as clubbing, leukonychia (whitening), or onyc ...
