Onychopathies vs onychomycosis: a challenge for familial physician

Publication date: 19/02/2016

It is very frecuently that patients, to note any change in the foil nail, assume that is fungal infection and seek medical treatment. It is our work to confirm or rule out the diagnosis of onychomycosis and give the appropriate treatment in each case.

We know that for some varieties clinics, the antifungal medications work best when they are administered oral, that should be taken by at least three months and that can have significant interactions with other medications.

For these reasons, in addition to the high cost of the latter is indis- sable corroborate the diagnosis before you start the treatment. The onicopathies constitute a large group of diseases that includes infectious lesions, as onychomycosis, but also non-infectious diseases, as the tumor lesions, inflames- nature, by medications or by systemic diseases

The application of cosmetics in the nails can also cause alterations and form part of the differential diagnosis.

The onychomycosis are the most frequent diseases (50%) followed by psoriasis, dystrophies traumatic, lichen planus, subungual exostosis, melanoniquia and tumor glómico and even some more serious as the epidermoid carcinoma or melanoma. As the Nail alterations have a very varied, depending on it will be the clinical manifestations that we observed.

While some onicopatías relate with congenital syndromes, some others go appearing as advancing age, mainly by the changes in the rate of growth of the nail foil. Others are caused by inflammation of the nail matrix, by detainees- tion of growth, or by the presence of neoplasias.
