Excoriated Acne: Acne Excoriée
∗∗∗
https://t.me/med1917
I only have a few pimples, but my facial skin keeps ip­ping over as if it’s been injured.
A 20-year-old female, L, came with the concern that although she doesn’t have many pimples, her facial skin often severely ips over. Upon closer examination, there are only a few acne lesions, but severe excoriations (scratched wounds) are noticeable. When asked, “Why do you hurt your skin like this?” she replied, “What are you talking about? I didn’t do that!” (Fig.83.1).
Of course, many people try to squeeze out comedones or pustules with their ngers or tools when they have acne on their face. However, excoriated acne (acne excoriée) refers to cases where young women with little or almost no acne show inammatory lesions with supercial scabs due to multiple excoriations (scratched wounds), often accompanied by per­sonality disorders, obsessive-compulsive disorders, or depression. It was rst reported in 1898 as “acne excoriée des jeunes lles (girls’ excoriated acne).” Excoriations are mainly caused by scratching or tearing with ngernails, resulting in round, irregular, linear lesions with red erosions and crusts, eventually leading to scars and post- inammatory hyperpigmentation. This is considered a defense mechanism to hide emotional disorders, and severe excoriated lesions appearing in patients with one or two minor acne lesions sig­nify emotional instability. Broad, red erosions with adherent crusts are distinctly different from the natural course of pap­ular or pustular acne lesions. Like neurotic excoriation, most female patients with excoriated acne deny or forget that they caused the excoriations. Therefore, it should be explained to the patient that such lesions can only occur when they dam­age their skin, and sometimes they may occur unconsciously

while asleep. However, even if they acknowledge that their actions caused the excoriations, they cannot suppress such behavior. Patients have severely distorted thoughts about their bodies, so a detailed history taking is necessary. Dermatitis artefacta can be accompanied, and treatment is not easy. Patients cannot break the obsessive-compulsive habit of scratching their faces. Therefore, psychiatric advice and treatment may be necessary, and habit reversal tech­niques are known to be effective. For erythema and scars, pulsed dye lasers or long-pulsed KTP lasers are effective, and for post-inammatory hyperpigmentation, Q-switched lasers are effective. Ms. L said, “Yes... I understand!” and it seems that she has a good understanding of the cause of this disease, and I sincerely hope that there will be an improve­ment in her symptoms in the future (Figs.83.2, 83.3, 83.4,
83.5, 83.6, 83.7 and 83.8).

Carotenoderma
I suddenly started liking tangerines so much that I bought a box and ate them, and now I think I have jaundice (Fig.84.1).
One day, the face of Ms. S, who is receiving skin care, looked quite yellow, so I was worried and said, “Your face looks a bit yellow!” She replied, “My hands are even yel­lower!” When I compared her hand with mine and Teacher Kim’s hand, her hand was incomparably yellow. I was sur­prised and quickly checked for jaundice in her eyes, but for­tunately, it was not jaundice (jaundice is when the whites of the eyes, i.e., the sclera, turn yellow). Relieved, I asked, “Have you been eating a lot of tangerines?” She replied, “Yes! I’ve recently become addicted to tangerines, and I’ve been buying them by the box and eating them!”.
Carotenosis is a condition where an increase in blood caro­tene levels leads to carotene deposition in the skin, causing yellow discoloration. One molecule of beta-carotene is converted into two molecules of retinol in the body. If caro­tene is not converted into retinol at a normal rate, it can exist in excess in the blood, and if carotene accumulates in tissues, especially the skin, due to an increase in blood car­otene levels, the palms of the hands and the soles of the Feet can turn orange-yellow color. Although it can be found in liver disease, diabetes, hypothyroidism, nephritis, and hyperlipidemia, it is most commonly seen in cases where fruits or vegetables high in carotene, such as carrots, oranges, tangerines, pumpkins, and spinach, are consumed in large quantities. It usually appears most commonly on the palms and soles, where the stratum corneum is thick, and also on the forehead, nose, upper eyelids, and behind

the ears. It is important to distinguish it from jaundice, as it shows a more yellowish color than jaundice, does not invade the mucous membranes including the sclera, and does not have the itching or changes in the color of urine and feces that can occur in jaundice. If differential diagno­sis is needed, liver function tests, blood tests, and urine tests are performed, and unless there are special circum­stances, limiting foods rich in carotene such as tangerines and oranges will naturally disappear. Tangerines are high in nutritional value and rich in vitamins, which are good for health and skin beauty, but as Confucius said, “Too much is as bad as too little.” (Figs.84.2, 84.3, 84.4, 84.5, 84.6 and
84.7).

When I take a hot bath or exercise a bit too much, my skin stings and small hives like millet appear (Fig.85.1).
21-year-old Mr. B says, “I don’t know when it started, but when I take a hot bath or exercise a bit too much, my skin stings and small hives like millet appear, which is really painful! Is it cholinergic urticaria?” These days, thanks to the internet, many people come in already knowing a lot, so there are many cases where no explanation is needed (Fig.85.2).
Cholinergic urticaria is a type of physical urticaria that occurs when the core body temperature rises by about 1°C due to hot baths, spicy food intake, excessive exercise, and mental stress. It accounts for 5–7% of all urticaria, typically starting in the 10s to 20s and is more common in men. As a mechanism of occurrence, excessive production of acetyl­choline has been reported in patients with cholinergic urti­caria, but it does not respond to oral anticholinergics and responds well to H1 antihistamines, suggesting the relevance of histamine. The possibility of a serum factor was also reported as symptoms appeared when the patient’s serum was injected into a monkey. It is characterized by the appear­ance of many very small wheals of 1–2mm and erythema­tous ares of 1–2cm around it. It mainly appears on the torso
and does not appear on the face and hands and feet. Generally, the rash disappears after 30–60min, but individual lesions can last longer depending on the case. Sometimes the lesions can merge or develop into angioedema. Many patients com­plain of stinging skin rather than itching, and systemic symp­toms such as sweating, abdominal pain, dizziness, headache, nausea, and vomiting can accompany. In Korea, there are reports of cholinergic urticaria accompanying cold urticaria, idiopathic generalized anhidrosis, and exercise-induced asthma. Sweating exercises or bathing in hot water around 43°C for 20–30min can induce typical cholinergic urticaria. The prognosis is relatively good, but it persists for more than 10years in 31% of patients, and the average duration of the disease is known to be 7.5years (3–16years). If cholinergic urticaria is suspected, the patient is exercised to sweat for 10–15 min (running, cycling, etc.) and the occurrence of characteristic small hives is observed for about an hour. However, precautions should be taken against exercise­induced anaphylaxis (Figs.85.3, 85.4, 85.5, 85.6, 85.7, 85.8 and 85.9).

To alleviate symptoms, rst avoid factors that can trigger or worsen them, and implement step-by-step drug treatment for symptom control. In fact, I also get severe hives when I
eat pupae or shrimp, so I feel more familiar with urticaria patients as if we share the same disease, and I explained the treatment method for urticaria to Mr. B with all my heart.

Idiopathic Guttate Hypomelanosis

I have a lot of white spots the size of beans on my arms, legs, and back. Could it be vitiligo? How should I treat it?
(Fig.86.1).
Mr. H, a 55-year-old man, came for treatment because he was curious about whether the white spots on his arms, legs, and torso, which had been noticeable one or two at a time and were gradually increasing in number, were vitiligo, and how to treat it, as he was reminded of the photos of vitiligo he had seen on the Internet. “Is this vitiligo? I’m worried because the number keeps increasing,” he said (Fig.86.2).
Idiopathic guttate hypomelanosis is an acquired leukoder­mic dermatosis that appears as round, white macules and patches with clear boundaries, mainly on the arms and legs. The size of the lesions is about 5mm in diameter on average, and more than 20 lesions are commonly found. They start to appear after the age of 10, with 50% observed in people over 40 and 70% in people over 60. As age increases, the number of lesions tends to increase, or their size tends to grow. The color of the hair in the lesion area does not change, and the lesions do not improve over time. There are no scales on the lesions, and there are no subjective symptoms such as itching. The cause is unknown, but it is presumed to be an aging phe-
nomenon caused by chronic sun exposure, it can occur due to skin friction, and it also shows a familial tendency. According to a report on 793 people in Korea, the average prevalence was 88% in people over 40, with 52% in men and 46% in women, showing no signicant gender difference. The occur­rence sites were lower legs (97%), forearms (94%), thighs (79%), upper arms (71%), back (46%), abdomen (27%), neck (18%), and face (5%) in order. 53% reported a family history, and as age increases, the prevalence increases, skin problems related to photoaging appear, and the occurrence rate was 56% in the group who responded that they scrub their skin, and 21% in the group who responded that they do not scrub their skin. It is reported that it is presumed to occur due to the combined action of intrinsic skin aging, photoaging, local trauma, etc., in addition to genetic factors. It is characterized by clear white macules about 5mm in size that occur mainly on the arms, legs, and back of the elderly, so it can be diag­nosed with the naked eye. Histologically, a decrease in the number of melanocytes and a quantitative decrease in mela­nin pigment can be conrmed in the lesions (Figs.86.3, 86.4,
86.5, 86.6, 86.7, 86.8, 86.9, 86.10 and 86.11).

This disease is a cosmetic issue and poses no risk. There is no effective treatment, but intralesional steroid injections or cryotherapy can be used, tretinoin is sometimes used for partial recovery of pigment and recovery of skin elasticity, and the effects of topical tacrolimus application and frac-
tional laser have been reported. I advised Mr. H to apply sun­screen well to prevent further deterioration and explained that there are no treatments with proven effectiveness yet, subtly expressing concern. Fortunately, he smiled brightly, saying, “As long as it’s not vitiligo, it’s okay!”
