Actinic keratosis

This in turn may further stimulate the abnormal proliferation that contributes to the development of AKs and carcinogenesis. Dysregulation of the p53 pathway can thus result in unchecked replication of dysplastic keratinocytes, thereby serving as a source of neoplastic growth and the development of AK, as well as possible progression from AK to skin cancer.

Journal of the European Academy of Dermatology and Venereology.

A lesion biopsy is performed if the diagnosis remains uncertain after a clinical physical exam, or if there is suspicion that the AK might have progressed to squamous cell carcinoma.

The most important cause of AK formation is solar radiation, through a variety of mechanisms. This treatment is relatively quick and easy to perform, but it requires a skilled operator.

Mutation of the p53 tumor suppressor gene, induced by UV radiation, has been identified as a crucial step in AK formation.

This page was last edited on 14 Decemberat It is often accompanied by multiple contact allergies and usually occurs in a background of either atopic, contact allergic, or seborrheic dermatitis, although it can occur de novo.

Unfortunately, in this case the treatment given to the patient was unknown. Histopathologic exam remains the gold standard. Its diagnosis is based on microbiological studies and on the identification in biopsies of the characteristic structures of the algae.

Although the potential for transformation into lymphoma has not been fully demonstrated, it brings great morbidity to our patients.

All methods are associated with some degree of pain, edemaand a relatively low rate of recurrence. Because sun exposure is rarely limited to a small area, most people who have an AK have more than one.

In the entire thickness of the dermis, granulomas with epithelioid histiocytes and large multi-nucleated cells containing internal structures similar to fungi were found figure 1A. Only comments seeking to improve the quality and accuracy of information on the Orphanet website are accepted.

Although it is difficult to establish specific infectious etiologies with biopsies, in the case of Prototheca it is easy as this organism has morphological characteristics that differentiate it from other agents.
