Fungal Infections

From Mediwikis

Tinea

Tinea infections present as ringworm. The different types of tine infections develop on different parts of the body.

  • T. Corporis - trunk/body
  • T. Cruris - groin
  • T. Capitis - scalp
  • T. Pedis - feet
  • T. Unguium - nails

Tinea Corporis presents with a dry, scaly, annular rash with central sparing. It is often itchy and has a raised, erythematous border. Tinea Pedis is otherwise known as 'athlete's foot', and presents with a similar, but often more widespread rash. Commonly this presents in between toes. Tinea Capitis presents with scaling and hair loss, and without treatment can lead to long term scarring and hair loss.

Candida

Candida is the most common cause of fungal infection, with candida albicans responsible for 90% of cases. It is associated with a number of risk factors:

  • Use of antibiotics
  • Intravenous catheters or prosthetic implants
  • Gastro intestinal tract surgery
  • Immune suppression mediated by steroids /HIV

It presents in a number of forms, including oropharyngeal, vaginal and candidal intertigo. Classically these are associated with a white frothy scale, or with erythematous lesions.

Pityriasis versicolor

This is a mild chronic infection of the stratum corneum, causing patchy discolouration of the skin.
