Home Skincare Device Induced Erythema Ab Igne on the Neck: An Emerging Disease Related to a New Technology / 대한피부과학회지

Erythema ab igne (EAI) is a persistent chronic skin condition that is characterized by reticulated macular hyperpigmented lesions caused by repeated exposure to infrared radiation. EAI has reemerged in recent years because of the increasing infrared exposure due to the use of new technologies, such as portable computers and automobile seat heaters. We report a case of a 54-year-old female patient presenting with asymptomatic mottled brownish plaque on both sides of her neck for 1 month prior to the visit. Patient history revealed that she had used a home skincare device for skin rejuvenation and relaxation. The clinicopathological features suggested a diagnosis of EAI. To our knowledge, there has only been one reported case of EAI on the neck related to a thermal pillow, and this was the first case of EAI related to the self-skincare devices. Herein, we report a rare case of EAI presenting on both sides of the neck due to the use of a modern home skincare device.

Eritema Ab Igne como dermatosis laboral: revisión de la literatura a partir un caso clínico / Erythema ab igne as a dermatosis labor: case report and literature review

El eritema ab igne es una entidad que fue descrita por primera vez por Buschke como “hitze melanosis” (melanosis inducida por calor), en piernas de personas que trabajaban frente a fuegos abiertos o estufas de carbón. Se define como lesiones cutáneas eritematosas o hiperpigmentadas en un patrón reticulado característico, secundario a la exposición crónica de bajos niveles de radiación infrarroja. A pesar que la aparición de calefacción centralha significado una dramática disminución en su incidencia, aún se describen casos de causa cultural, médica o laboral. Una de susconsecuencias más graves es la posibilidad de aparición de un carcinoma espinocelular sobre la lesión. A continuación se presenta un caso clínico de etiología laboral y se realizará una revisión de la literatura.

Erythema ab igne is an entity that was first described by Buschke as “hitze melanosis” (heat-induced melanosis), in the legs of people working in front of open fires or coal stoves. It is defined as erythematous or hyperpigmented skin lesions in a reticulated pattern. The main cause is the chronic exposure tolow levels of infrared radiation. Although the occurrence of central heating has meant a dramatic decrease in incidence, cultural, medical or occupational causes are still described. One of the most serious consequences is the possibility of develoging an squamous cell carcinoma. We present a case of occupational aetiology and a review of the literature.

A Case of Thermal Keratosis along with Erythema Ab Igne / 대한피부과학회지

We report a case of thermal keratosis with erythema ab igne which occurred on the dorsal side of a patient's left hand due to chronic exposure to infrared rays. A 62-year-old male presented with reticular hyperpigmentation on the dorsal side of his left hand and left knee along with multiple hyperkeratotic nodules on the dorsal side of his left hand without any symptoms. He had a hobby of playing internet games with a heater on his left side. A skin biopsy of the hyperkeratotic lesion showed hyperkeratosis and acanthosis in the epidermis. The dermis revealed many elastic fibers and superficial perivascular monocytic infiltration. The patient was diagnosed with thermal keratosis and erythema ab igne due to his history of chronic infrared exposure, distinctive clinical characteristics and the biopsy results. The application of topical steroid with the recommendation to cease exposure to heaters resulted in the almost disappearance of the papules and a little restoration of the skin color.

Erythema Ab Igne Caused by Weight Loss Heating Pad / 대한피부과학회지

Erythema ab igne (EAI) refers to the development of persistent areas of reticular erythema, often with pigmentation, at the sites of repeated exposures to heat, usually from open hearths. Although the incidence of EAI has declined due to the advent of central heating, various other causes have recently been reported, including hot water bottles, heating pads used to treat ailments, heated blankets, car heaters, and laptop computers. We present a case of 23-year-old Korean woman with an asymptomatic patch on her trunk, which had occurred a month before due to use of weight loss heating pad for weight reduction.

Erythema Ab Igne Associated with Frequent Bathing of Feet in Hot Water / 대한피부과학회지

Erythema ab igne is a relatively uncommon skin lesion caused by chronic exposure to low levels of infrared heat from open fires or stoves, and is characterized by reticulated hyperpigmentation on the exposed skin. Recently, exposure to various 'new' heat sources, such as heated furniture, car heaters, or even laptop computers, has been reported to cause this condition. We present a case of 31-year-old Korean woman with reticulated hyperpigmentation on her feet, which had occurred due to bathing her feet in hot water on a daily basis.
