This in turn may further stimulate the abnormal proliferation that contributes to the development of AKs and carcinogenesis.

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.

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.
