Abstract
BACKGROUND Severity of Alopecia Tool (SALT) is widely used to assess the severity of alopecia areata (AA). However, physician-related subjectivity exists in SALT scoring (S1-5), especially with initial inspection in the clinical practice. This study investigated two-dimensional planimetric method to calculate actual surface area of AA, validating SALT scoring. MATERIALS AND METHODS SALT score was measured twice in each patient based on "initial" inspection in the clinic (SALT-I) and retrospective assessment of the "photograph" (SALT-P). Planimetric surface area was calculated by Image J program. Subgroup analysis was performed depending on the agreement between SALT-I and -P; score was described in the order of SALT-I and SALT-P. RESULTS A total of 93 subjects were enrolled. Planimetric surface area (cm2 ) of SALT-I was 2.5-74.9 (S1), 48.8-100.6 (S2), 83.6-205.4 (S3), and 282-367.9 (S4), while SALT-P was 2.5-59.2 (S1), 41.6-205.4 (S2), 48.8-183.2 (S3), and 282-367.9 (S4). In subgroup analysis, SALT-I and SALT-P agreed group showed planimetric surface area (cm2 ) as 2.5-59.2 (S1-1), 64.2-100.6 (S2-2), 168.3-183 (S3-3), and 282.6-367.9 (S4-4). Disagreed group showed the value as 54.7 (S1-2), 41.6-74.9 (S2-1), 83.6-205.4 (S2-3), and 48.8-88.6 (S3-2). CONCLUSION SALT-P was more clearly correlated with actual surface area than SALT-I. Planimetric surface area measurement could be used as a supplementary method especially in the S1 to S3, suggesting 60 cm2 , 100 cm2 , and 200 cm2 as objective cutoff values to differentiate S1, S2, and S3.

Abstract
BACKGROUND Alopecia areata (AA) is common non-scarring hair loss disease. Sleep distrubance has been regarded as a triggering or aggravating factor for AA. However, objective evaluation of sleep disturbance and its clinical effect on AA has not been clearly demonstrated. OBJECTIVE This study investigated objective sleep evaluation tool for AA patients and their clinical correlation. METHODS Patients presenting with new-onset AA or recurrences of pre-existing AA were included, and those who reported sleep disturbance in the preliminary survey were designated as the sleep disturbance group (SD group). Sleep quality was investigated for them using three self-administered questionnaires: Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), and Epworth Sleep Scale (ESS). Demographic information and clinical features of AA were analyzed according to sleep quality. RESULTS A total of 400 participants were enrolled, and 53 were categorized into the SD group. The incidence of stressful events was significantly higher in the SD group (54.7%) than in the non-SD group (25.1%) (p<0.001). Based on the PSQI, 77.3% of participants were objective poor sleepers (score of 5 or more), and they showed a significantly higher incidence of stressful events compared to good sleepers (p=0.019). The proportion of poor sleepers was significantly lower in patients with mild AA (S1) than in those with moderate to severe AA (S2~S5) (p=0.045). CONCLUSION This study demonstrated a positive correlation among stress, SD, and AA. The degree of SD was objectively represented by the PSQI score, showing different scores according to AA severity.

Abstract
After anaplastic large-cell lymphoma (ALCL) was first described by Stain in 1985, there have been several histological variants of ALCL reported. There are classified histological subtypes of ALCL, such as lymphohistiocytic, small cell, Hodgkin-like, composite pattern, and other less common variants including neutrophil-rich ALCL. A 63-year-old male patient presented with erythematous exophytic mass on the left lower leg. In the past, his condition had been diagnosed as abdominal primary cutaneous ALCL (pcALCL), which recurred as systemic ALCL (sALCL) in the left bronchus. After treatment, he achieved complete remission. Histopathologic examination showed large-sized pleomorphic, anaplastic mitotic tumor cells, several neutrophils, and a few lymphocytes. Neutrophil-rich ALCL is a rare histological variant of ALCL. It is characterized by the presence of CD30-positive anaplastic tumor cells with numerous neutrophil infiltrations. Neutrophil-rich ALCL responds well to treatment but tends to recur. There were four cases reported to have recurrent neutrophil-rich ALCL. All cases were diagnosed with neutrophil-rich pcALCL prior to recurrence. Three cases had local recurrence, and only one case relapsed as sALCL. Herein, we present the first case of neutrophil-rich ALCL recurring as sALCL twice.

Abstract
By utilizing a multimodal nonlinear optical system that combines coherent anti-Stokes Raman scattering and second harmonic generation to investigate biological characteristics of dermal tissues ex vivo, we demonstrate the potential feasibility of using this optical approach as a powerful new investigative tool for future biomedical research. For this study, our optical system was utilized for the first time to analyze lipid and collagen profiles in cereblon knockout (KO) mouse skin, and we were able to discover significant alterations in the number of carbon-carbon double bonds (wild-type vs. cereblon KO; NCC : 0.75 vs. 0.85) of skin fatty acids in triacylglycerides as well as changes in dermal collagen fibers (25% reduction in cereblon KO). By adopting our optical system to biological studies, we provide researchers with another diagnostic approach to validate their experimental results, which will significantly advance the state of biomedical research.

Abstract
Poster session 2, September 22, 2022, 12:30 PM - 1:30 PM Dermatophyte invades the stratum corneum and infects the skin, nails, and hair, mostly resulting in superficial infection. Deep dermatophytosis involving dermis and subcutaneous layer was rarely reported in immunocompromised state. Herein, we report a case with deep dermatophytosis caused by Trichophyton (T.) rubrum. A 71-year-old woman presented with multiple erythematous exophytic and subcutaneous nodules located on both lower legs. She was taking immunosuppressive agents for rheumatoid arthritis and had taken antifungal agents for tinea pedis and onychomycosis, which was improperly ceased. Histopathologic examination revealed pseudoepitheliomatous epidermal hyperplasia with microabscess formation in epidermis and diffuse granulomatous inflammation consisting of multinucleated giant cells, lymphocytes, neutrophils, and histiocytes in dermis. Imuunohistochemical staining with periodic acid-schiff (PAS) and Gomori methenamine silver (GMS) showed septate and branched fungal hyphae in dermis. Trichophyton rubrum was identified in fungal culture with tissue and confirmed through phylogenetic analysis of internal transcribed spacer (ITS) and large subunit regions (LSU) in ribosomal RNA. Prior to identification of causative organism, her condition deteriorated into septic shock. Amphotericin B was administered empirically for 6 days in order to prevent hematogenous dissemination and skin lesions were simultaneously resolved. Since deep dermatophytosis appears in various clinical manifestations, it is easy to be mistaken for another disease. If treatment is delayed, immunocompetent patients can progress to severe disease courses like hematogenous dissemination, so clinicians should differentiate this disease and conduct treatment at an appropriate time.

Abstract
Cereblon (CRBN) is a substrate recognition protein in the E3-ligase ubiquitin complex. The binding target of CRBN varies according to tissues and cells, and the protein regulates various biological functions by regulating tissue-specific targets. As new endogenous targets of CRBN have been identified over the past decade, the physiological and pathological functions of CRBN and its potential as a therapeutic target in various diseases have greatly expanded. For this purpose, in this review article, we introduce the basic principle of the ubiquitin-proteasome system, the regulation of physiological/pathological functions related to the endogenous substrate of CRBN, and the discovery of immunomodulatory imide drug-mediated neo-substrates of CRBN. In addition, the development of CRBN-based proteolysis-targeting chimeras, which has been actively researched recently, and strategies for developing therapeutic agents using them are introduced. These recent updates on CRBN will be useful in the establishment of strategies for disease treatment and utilization of CRBNs in biomedical engineering and clinical medicine.

Abstract
Palisading encapsulated neuroma is a rare, benign, cutaneous nerve sheath tumor. It usually occurs as an asymptomatic solitary skin-colored papule and commonly affects the nose and cheeks. Sometimes, it involves other sites, including the shoulder, upper arm, and trunk, but rarely involves the oral mucosa, including that of the lip. In our case, a 63-year-old female patient complained of a pinkish rubbery nodule on her lower lip. Histopathologic examination demonstrated a well-circumscribed nodule encapsulated by connective tissue stroma in the dermis. The nodule consisted of palisading spindle-shaped tumor cells with wavy and basophilic nuclei. The cells were arranged in streaming fascicles with multiple clefts and were strongly positive for S-100 proteins. To our knowledge, only three cases of palisading encapsulated neuroma on the lower lip have been reported in the Korean literature. Herein, we report a rare case of an oral palisaded encapsulated neuroma.

A common cause of drug hypersensitivity reactions is iodinated contrast media (ICM). ICM-induced hypersensitivity had been considered to be a non-immunological reaction, but evidence for an immunological mechanism has increased recently. Thus, we evaluated whether HLA-A, -B, and -C alleles were associated with ICM-induced hypersensitivity. In total, 126 patients who underwent contrast-enhanced computed tomography studies through outpatient clinics at a tertiary referral hospital between 2008 and 2012 were assessed. Sixty-one patients experienced ICM-induced hypersensitivity and the remainder, 65, were ICM-tolerant patients (control). ICM-induced hypersensitivity patients showed 51 with immediate, 7 with non-immediate, 3 with both or mixed type. HLA-A, -B, and -C genotyping was performed using a PCR sequence-based typing method. Four kinds of ICM were used: iopromide, iohexol, iobitridol, and iodixanol. The most used ICM among the hypersensitivity patients was iopromide. Significant difference in the frequency of HLA-B*58:01 (odds ratios [OR], 3.90; p = 0.0200, 95% confidence interval [CI], 1.16-13.07) was observed between ICM-induced immediate hypersensitivity and control. There were statistically significant differences in the frequencies of the HLA-B*38:02 (OR, 10.24; p = 0.0145; 95% CI, 1.09-96.14) and HLA-B*58:01 (OR, 3.98; p = 0.0348; 95% CI, 1.03-15.39) between iopromide-induced immediate hypersensitivity and control. The mechanism of ICM-induced hypersensitivity remains unknown, but this study showed associations, although weak, with HLA-B*58:01 alleles for ICM-induced immediate hypersensitivity and HLA-B*38:02 and HLA-B*58:01 for iopromide-induced immediate hypersensitivity as risk predictors. Further studies are needed to validate the associations in larger samples and to identify the functional mechanism behind these results.

Abstract
Cereblon (CRBN) is a substrate receptor of the cullin-RING E3 ubiquitin ligase (CRL) complex that mediates the ubiquitination of several substrates. In this study, CRBN knockout (KO) mice exhibited decreased levels of stratum corneum hydration (SCH) and collagen I expression with an elevated protein level of matrix metalloprotease 1 (MMP1). The absence of cereblon in the skin of CRBN KO mice mimics the damage caused by narrowband ultraviolet B (NB-UVB). The primary CRBN deficient mouse embryonic fibroblasts (MEFs) undergo G2/M-arrested premature senescence via protein signaling of p38 MAPK and its dependent p53/p21pathway. The absence of CRBN induced the markers of cellular senescence, such as the senescence-associated heterochromatin foci (SAHF), SA-β-Gal staining, and p21 upregulation while the ectopic expression of CRBN reversed the phenotypes of SA-β-Gal staining and p21 upregulation. Reversion of the decreased protein level of collagen I was demonstrated after the reintroduction of the CRBN gene back into CRBN KO MEFs, validating the promising role of CRBN as a potential regulator for the function of the skin barrier and its cellular homeostasis.

Abstract
Background Oral alitretinoin is effective in the treatment of chronic hand eczema (CHE), and ≥12 weeks of alitretinoin treatment has been shown to be effective in Korean patients. However, in the real world, a considerable number of patients discontinue alitretinoin, which leads to treatment failure. Objective To evaluate the compliance rate of alitretinoin treatment and explore common reasons for poor compliance in patients with CHE in the real world. Methods We retrospectively reviewed the electronic medical records of CHE patients treated with alitretinoin. We defined ‘poor-compliance’ as subjects who were treated with alitretinoin for <12 weeks and ‘good-compliance’ as subjects who were treated with alitretinoin for ≥12 weeks. We reviewed the demographics, dose, and duration of alitretinoin usage, efficacy, and reasons for poor compliance. Results A total of 137 subjects were enrolled, and 77 (56.2%) did not complete the 12-week treatment with alitretinoin. Among them, the non-improvement rate was significantly higher in the poor-compliance group than in the good-compliance group (p<0.01). The main reasons for the alitretinoin cessation in the poor-compliance group were insufficient response (40.8%), followed by high cost (34.7%), and adverse events (24.5%). Conclusion Alitretinoin appears the preferred long-term treatment option for CHE. Although there are complaints about late efficacy, cost, and side effects, following proper explanation, these should not justify discontinuation. Physicians need to recognize the reasons for poor compliance with alitretinoin for each patient and suggest continuing alitretinoin for the successful treatment of CHE.

Abstract
Congenital triangular alopecia (CTA) is a form of circumscribed, noncicatricial, and noninflammatory hair loss. It manifests as a triangular or oval-shaped alopecic patch on the frontotemporal region of the scalp and rarely involves the temporoparietal or occipital area. That is why it is also called temporal triangular alopecia. However, there has been just one case reported in the middle frontal area. Here, we report a successfully treated case of CTA in a 17-year-old boy who was born with a 2.5 cm × 3.5 cm alopecic patch in the middle frontal area.

Abstract
Background Recently, the number of nationwide medical researches on psoriasis using the National Health Insurance Service database has been on the rise. However, identification of psoriasis using diagnostic codes alone can lead to misclassification. Accuracy of the diagnostic codes and their concordance with medical records should be validated first to identify psoriasis patients correctly. Objective To validate the diagnostic codes of psoriasis (International Classification of Diseases, 10th Revision L40) and to find the algorithm for the identification of psoriasis. Methods We collected medical records of patients who received their first diagnostic codes of psoriasis during 5 years from five hospitals. Fifteen percent of psoriasis patients were randomly selected from each hospital. We performed a validation by reviewing medical records and compared 5 algorithms to identify the best algorithm. Results Total of 538 cases were reviewed and classified as psoriasis (n=368), not psoriasis (n=159), and questionable (n=11). The most accurate algorithm was including patients with ≥1 visits with psoriasis as primary diagnostic codes and prescription of vitamin D derivatives. Its positive predictive value was 96.5% (95% confidence interval [CI], 93.9%~98.1%), which was significantly higher than those of the algorithm, including patients with ≥1 visits with psoriasis as primary diagnostic codes or including ≥1 visits with diagnostic codes of psoriasis (primary or additional) (91.0% and 69.8%). Sensitivity was 90.8% (95% CI, 87.2%~93.4%) and specificity was 92.5% (95% CI, 86.9%~95.9%). Conclusion Our study demonstrates a validated algorithm to identify psoriasis, which will be useful for the nationwide population-based study of psoriasis in Korea.

Abstract
Background Telogen effluvium (TE) is characterized by massive hair shedding and results from an abrupt conversion of anagen to telogen. Differentiation of TE with other hair disorders showing massive hair shedding is difficult. Objective To evaluate the morphologic characteristics of pulled out hair of TE. Methods We analyzed microscopic examination of pulled out hairs by hair pull test in TE patients, and compared these hairs with pulled out hairs in diffuse alopecia areata (AA) patients and healthy volunteers. Results Hair microscopic examination in 44 TE patients (370 hairs) and 30 healthy volunteers (295 hairs) were as follows: typical club hair, 32.7%, 62.7%; club hair with tail, 23.5%, 23.7%; club hair with remnant sheath, 23.0%, 6.8%; club hair with both tail and remnant sheath, 18.9%, 5.4%; and unclassified hair, 1.9%, 1.4%. The examination in 7 diffuse AA patients (63 hairs) was as follows: typical club hair, 23.9%; atypical club hair, 47.7%; and distinctive AA hair, 28.4%. There was statistical difference between TE patients and healthy volunteers group (p=0.000). Conclusion Increased atypical club hair in microscopic hair examination might be characteristics of TE.

Abstract
A ‘collision’ tumor refers to the existence of two different neoplasms within the same tumor. Sometimes, the term ‘biphasic tumor’ is also used. However, a ‘collision’ tumor is defined as the occurrence of two neoplasms within proximity of each other yet maintaining distinctly defined, separate boundaries. In contrast, a ‘biphasic’ tumor demonstrates two or more phenotypically distinct neoplastic cell populations merging within the same space. Here, we report a case of collision tumor associated with sarcomatoid eccrine porocarcinoma and basal cell carcinoma arising in a 57-year-old male patient.

Abstract
Background There is growing interest in alopecia among the general population. Many people obtain information from easily accessible media rather than from doctors; thus, the media can play an important role in shaping public opinion. Objective The goal of this study was to evaluate the content and reliability of newspaper articles on alopecia. Methods Newspapers were categorized into three groups: one group of print newspapers and two groups of online newspapers. Online newspapers were further divided into two groups according to type of publishing company; one publishes both print and online newspapers and the other publishes online newspapers only. The most frequently subscribed or circulated newspaper in each group was selected. Articles containing information on alopecia were selected from 3 years of each newspaper and evaluated for reliability. Results Most articles in each group used the general term "alopecia" instead of naming a specific hair loss disease. The majority of articles were based on consultation with experts. Assessment of the accuracy of articles with three grade scales showed that the percentage with high accuracy was 38.9%, 47.2%, and 23.3%. Assessment of reliability scores for five selected articles in each group showed that there were statistically significant differences between common readers and dermatologists (p<0.05). Conclusion The results of this study suggest that closer monitoring of the media is required to supply easily accessible, balanced, and trustworthy information regarding alopecia.

Abstract
Endovascular interventional procedures are widely used for the treatment of intracranial vascular lesions. However, they sometimes produce reversible alopecia, known as radiation-induced temporary alopecia, depending on the radiation dose. Radiation-induced temporary alopecia manifested as rectangular alopecic patches without signs of inflammation, reflects damage to the keratinocytes in the hair matrix of anagen hair follicles, due to the sensitivity of these cells to radiation. The characteristics of radiation-induced temporary alopecia are similar to those of alopecia areata as follows: (1) clinical findings of well-defined alopecic patches and (2) dermoscopic findings of yellow dots, black dots, and short vellus hairs. The two conditions can be distinguished according to whether there is any history of endovascular interventional procedures, and by the shapes of the lesions and the inflammation status on histopathologic examination. A hair microscopic examination is a useful diagnostic tool in patients with hair loss disease, but the features of radiation-induced temporary alopecia have not been well described. Here, we report three cases of radiation-induced temporary alopecia preceded by endovascular procedures, including stent insertion and coil embolization.

Abstract
Introduction Teledermatology has contributed to the enhanced accessibility of underserved populations. This study investigated the prevalence and clinical outcomes of dermatologic diseases in prisoners in Korea through live interactive teledermatology (LITD) Method The medical records of patients in a Busan prison, who interacted with a dermatologist using LITD from July 2013 to August 2016, were reviewed retrospectively. Results The mean age of the 406 patients enrolled in the study was 39.0 years and 91.4% were male. Infectious disease (42.8%) was the most common type of disease, followed by eczematous disease (29.4%) and diseases of the skin appendages (14.5%). Among the 187 (38.2%) patients who had a follow-up consultation, 162 (86.7%) showed clinical improvement, whereas 21 showed either no change or a worse clinical outcome. Twenty patients were diagnosed with different types of dermatologic disease at follow-up consultations. Discussion LITD can contribute to a favourable clinical outcome and may thus be an effective alternative to face-to-face consultation in prisoners and other underserved populations.

Abstract
BACKGROUND/OBJECTIVES The need for dermatology consultations for neonatal intensive care unit (NICU) patients is increasing, but no study has systemically examined the skin diseases of patients in NICUs. The aim of this study was to analyze dermatology consultations in the NICU of a tertiary medical center in Korea and determine the effect of the dermatology consultation on the clinical course and management of the patients after the consultation. METHODS The medical records of patients undergoing dermatologic consultation during their stay in a NICU between March 2009 and February 2016 were reviewed retrospectively. RESULTS Sixty patients were enrolled in this study; the male-to-female ratio was 1:1.1, and mean age at the time of consultation was 3.7 weeks. Mean gestational age was 33.7 weeks, and 35 of the subjects (58.3%) were preterm neonates. Mean birth weight was 2.14 kg (range 550-4,200 g). The most-common disease category was birthmarks and neoplasms (20.0%), followed by eczematous dermatoses (18.3%), skin appendageal disease (16.7%), and infectious disease (13.3%). CONCLUSION This study identified the dermatologic problems of neonates in a NICU and can raise dermatologists' awareness of the types of patients they may encounter in a NICU.

Abstract
Allopurinol-induced severe cutaneous adverse reactions (SCARs) such as Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome are reportedly associated with the HLA-B*58:01 genotype. Three patients who developed SCARs after allopurinol administration were subjected to HLA-B genotyping and lymphocyte activation test (LAT) to evaluate genetic risk and to detect the causative agent, respectively. All three patients given allopurinol to treat gout were diagnosed with DRESS syndrome. Symptom onset commenced 7-24 days after drug exposure; the patients took allopurinol (100-200 mg/d) for 2-30 days. HLA-B genotyping was performed using a polymerase chain reaction (PCR)-sequence-based typing (SBT) method. All patients had a single HLA-B*58:01 allele: HLA-B*13:02/*58:01 (a 63-year-old male), HLA-B*48:01/*58:01 (a 71-year-old female), and HLA-B*44:03/*58:01 (a 22-year-old male). Only the last patient yielded a positive LAT result, confirming that allopurinol was the causative agent. These findings suggest that patients with HLA-B*58:01 may develop SCARs upon allopurinol administration. Therefore, HLA-B genotyping could be helpful in preventing serious problems attributable to allopurinol treatment, although PCR-SBT HLA-B genotyping is time consuming. A simple genotyping test is required in practice. LAT may help to identify a causative agent.

Abstract
An 18-year-old male visited our department complaining of recurrent episodes of an itchy rash after hand washing, showering/bathing, drinking water, and getting rain-soaked. He was diagnosed with aquagenic urticaria after a water provocation test and histopathologic examination. Five months of antihistamine treatment successfully prevented further wheal formation. Aquagenic urticaria is a very unusual form of physical urticaria caused by contact with water. It manifests as pruritic small wheals surrounded by erythema within 30 minutes of exposure. The condition can be diagnosed by a water provocation test. Systemic antihistamines are the first-line treatment, with anticholinergics, phototherapy, or barrier cream used alternatively or additionally. Four cases of aquagenic urticaria have been reported in Korea, but no histopathologic evaluation was reported in the English or Korean literature. Herein, we provide both a case report of aquagenic urticaria diagnosed by the water provocation test and histopathologic examination results for this patient.

Abstract
BACKGROUND Alopecic and aseptic nodule of the scalp (AANS) is a rare disease entity first reported in 1992 as pseudocyst of the scalp (PCS). Controversy exists regarding the histopathology and etiology of reported cases. OBJECTIVE We performed this study to analyze the clinical and histopathologic features of AANS/PCS in Korean patients. METHODS A retrospective review of medical records from 2008 to 2013 at Inje University Busan Paik Hospital was performed. RESULTS Eleven patients were enrolled. All patients were male, and their mean age was 21.6 years. Most patients had a solitary nodule (10/11) located predominantly on the vertex. The mean nodule size was 20 mm. Inflammatory cell infiltration in the deep dermis was a histologic feature of AANS/PCS. Eight patients showed granulomatous infiltration. All patients were treated with short-term antibiotics and intralesional steroid injection. CONCLUSION Our results suggest that dermatologists should consider AANS when diagnosing an alopecic nodule on the scalp.

Abstract
Here, we report a case of Cowden syndrome with an unusual clinical course of late-onset oral papillomatosis and a novel germline PTEN mutation. Cowden syndrome is the most common phosphatase and tensin homolog hamartomatous tumor syndrome. It is characterized by multiple hamartomas in the gastrointestinal tract and mucocutaneous lesions such as trichilemmomas, oral papillomatosis, facial papules, and acral keratoses. Patients with Cowden syndrome have a higher risk of malignancies, especially breast, colon, and thyroid cancers. A 53-year-old female presented with cobblestone-like papillomatous papules on the lower gums that developed 1 year earlier. She had no other mucocutaneous lesions besides oral papillomatosis. Gastrointestinal endoscopy and colonoscopy revealed multiple hamartomas in the stomach and colon. The patient had a history of breast cancer and multinodular goiter diagnosed 4 and 5 years ago, respectively. She was diagnosed with Cowden syndrome and a novel PTEN mutation was confirmed by direct sequencing.

Abstract
Acute localized exanthematous pustulosis (ALEP) is a localized variant of acute generalized exanthematous pustulosis, which is characterized by the eruption of multiple scattered pustules following drug administration. A 26-year-old woman presented with multiple erythematous pustules on her face, which had appeared three days after taking antibiotics. Histopathological findings showed subcorneal pustules and mixed inflammatory cell infiltration in the dermis. The pustules were resolved within 2 weeks after the patient discontinued the antibiotics. Herein, we present a case of a woman with a cutaneous drug reaction consistent with ALEP that occurred subsequent to administration of antibiotics.
