In xeroderma pigmentosum, a rare genodermatosis, transmitted as an autosomal recessive disorder, excessive solar damage to the skin develops at an early age. The disease is characterized by cutaneous, ocular, neurological and oral changes. Oral features in the form of early development of squamous cell carcinoma, usually at the lower lip and tip of the tongue may be seen. The disorder is associ...

illions of vacationers deliberately expose themselves to excessive UV radiation. As a result, the risk of UVrelated skin damage is rapidly increasing. Sun worshippers thus have to expect an increased risk for actinic keratoses (a carcinoma in situ). Most recent estimates prove that about 8 million Germans suffer from actinic keratoses. There is an estimated prevalence of about 15 percent among ...

Actinic keratoses are rough, scaly lesions that commonly occur on sun-exposed areas of the skin. The prevalence of the condition increases with age. Actinic keratoses are thought to be carcinomas in situ, which can progress to squamous cell carcinomas. The decision to treat can be based on cosmetic reasons; symptom relief; or, most importantly, the prevention of malignancy and metastasis. Treat...

Ingenol mebutate gel (Picato) for actinic keratoses.

Seborrheic keratoses can often be found in elderly people. In general, they appear gradually. In cases of a sudden eruption with itching it might be paraneoplastic. Although some authors doubt the existence of the paraneoplastic Leser-Trélat syndrome, we present a case of sudden eruption of seborrheic keratoses connected with a newly diagnosed renal cell carcinoma. As far as we know, this is th...

INTRODUCTION Seborrheic keratoses are very common findings in elderly patients. However, a sudden onset and dramatic increase in the number and size of these benign lesions deserves special attention, since this may represent the Leser Trélat sign, a rare paraneoplastic cutaneous syndrome. CASE PRESENTATION A 92-year-old female presented to our clinic with multiple eruptive seborrheic keratos...

The evidence for PDT in individuals who have nonhyperkeratotic actinic keratoses includes randomized controlled trials (RCTs). Relevant outcomes are symptoms, change in disease status, quality of life, and treatment-related morbidity. Evidence from multiple RCTs has found that PDT improves the net health outcome in patients with nonhyperkeratotic actinic keratoses on the face or scalp compared ...
