Argon laser treatment of small keratoacanthomas in difficult locations

International Journal of Dermatology
R A Neumann, R M Knobler

Abstract

Seventeen patients (mean age, 64.7 years) with solitary keratoacanthomas (KA) located on the face and auricles were treated with the argon laser. All lesions were less than 10 mm in diameter and had been present for 2-10 weeks (mean, 3.8 weeks). The diagnosis was made clinically and was confirmed by histology. The lesions were treated with the argon laser using the continuous exposure technique with a power setting of 4.5 watts (W) and a beam diameter of 1 mm. Complete re-epithelialization occurred within 14-21 days. Excellent treatment results were achieved in 65% of the patients. Thirty-five percent healed with mild scarring. During a follow-up period of 2 years no recurrences were noted. The use of the argon laser for removal of small KAs in difficult locations, which would often require invasive surgery, appears to be an effective additional treatment modality.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Rh Isoimmunization

Rh isoimmunization is a potentially preventable condition that occasionally is associated with significant perinatal morbidity or mortality. Discover the latest research on Rh Isoimmunization here.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.

Enzyme Evolution

This feed focuses on molecular models of enzyme evolution and new approaches (such as adaptive laboratory evolution) to metabolic engineering of microorganisms. Here is the latest research.
