Babies with extremely rare dermatitis


A few days later, the nodules darken, black. Two pediatric patients went to the Central Dermatology Hospital for an examination.

Professor, Dr. Tran Hau Khang, President of the Vietnam Dermatology Association, Former Director of the Central Hospital of Dermatology, on December 19, said that children with rare dermatological diseases, the literature called dermatitis due to sunlight and plants (Phytophotodermatitis). The disease appears very little in Vietnam, is a form of phytophotodermatitis, caused by exposure to two factors, which are chemicals of plants, acting as sun and sun sensitizers.

When in the sun, the professor said, if exposed to plants containing a substance especially furocoumarins, long-wavelength ultraviolet UVA (320-400 nm) rays in the sun will activate the substance. This and causes a strong, inflammatory skin reaction with the above mentioned symptoms. Pigmentation cells in the skin are also stimulated, increasing the production of melanin, causing the skin in the contact area to darken and darken.

“The furocoumarins found in plants such as oranges, lemons, tangerines, celery, parsley, figs, fig trees … are photosensitive, so when activated by UVA rays in the sun with intensity strong inflammation of the skin and hyperpigmentation “, professor said.

Sun-induced dermatitis is not too difficult to treat. This is an inflammatory skin reaction due to contact, so a general rule of thumb is to treat inflammation by applying corticosteroid anti-inflammatory drugs and taking anti-allergy medications. The dark spots due to hyperpigmentation after treatment will also slowly disappear. If superinfection can use topical or systemic antibiotics depending on disease severity.

However, because this is a rare disease, so for inexperienced people, often misdiagnosed, leading to wrong treatment, making the disease progress.

To effectively prevent phytophotodermatitis, experts recommend, if not necessary, not to go out in the sun between 10am and 3pm. This is the stage of intense UV light intensity. If you have unexpected work or need to travel or work outdoors, wear a hat with a wide brimmed hat, apply sunscreen, wear long pants and a long-sleeved shirt.

Hands and exposed skin should be washed with soap or cold water if you are working outdoors and have been in contact with vegetables, plants, especially families containing Furocoumarins as mentioned above. When gardening or planting plants, it is important to wear protective gloves.

When there are symptoms of dermatitis, dermatologists need to be diagnosed and treated promptly.
