Case Report: Acute Pancreatitis in an Uncontrolled Diabetic Patient Presenting With a Skin Rash Later Found to Be Eruptive Xanthoma, a Dermatological Manifestation and Diagnostic Clue to Recognizing Hypertriglyceridemia as the Cause of Disease.

Acute pancreatitis results from any insult that leads to inflammation of the organ. Hypertriglyceridemia is one of the risk factors associated with acute pancreatitis. The typical presentation is abdominal pain, nausea, and vomiting. We present a unique case in which the patient's condition was further complicated by diabetic ketoacidosis. Consequently, he presented somnolent to the emergency room, providing a limited history only pertaining to generalized weakness and a skin rash. The patient was found to have hypertriglyceridemia-induced pancreatitis, which was appropriately managed in the intensive care unit. The skin lesions were diagnosed as xanthomas, which are associated with hypertriglyceridemia and acute pancreatitis secondary to hypertriglyceridemia. The patient was discharged on fibrate therapy, dietary counseling, and strict monitoring by his primary care physician. This unique case highlights the importance of recognizing dermatological conditions and their associated diseases to allow for prompt diagnosis and treatment in the face of limited history.

Cystic fibrosis dermatitis arthritis syndrome: A series of four cases.

Dermatologic manifestations of cystic fibrosis (CF) include nutrient deficiency dermatoses, vasculitis, transient reactive papulotranslucent acrokeratodema, digital clubbing, and increased rates of atopy and drug reactions. Few cases of a characteristic eruption in patients with episodic arthritis of CF have been described with prior reports primarily occurring outside of the dermatology literature. We report four cases consistent with this presentation to add to the literature and propose a new and unifying name to recognize this entity as cystic fibrosis dermatitis arthritis syndrome (CF-DAS). Clinical suspicion should remain high in young female patients with cystic fibrosis presenting with episodic joint pain and rash, independent of pulmonary exacerbations.

Schnitzler-Like Syndrome Presenting With IgG Kappa Monoclonal Gammopathy: A Case Report and Review of Diagnostic and Therapeutic Challenges.

Schnitzler syndrome (SS) is a rare autoinflammatory disorder characterized by a constellation of symptoms that include chronic urticarial rash, recurrent fever, arthralgias/arthritis, and monoclonal gammopathy, typically involving immunoglobulin M (IgM). However, cases with overlapping clinical features but lacking specific criteria fall under the umbrella of Schnitzler-like syndromes. This case report describes a 40-year-old male with Schnitzer-like syndrome and underscores the diagnostic complexities and therapeutic challenges of Schnitzer-like syndrome with IgG kappa monoclonal gammopathy, highlighting the need for a comprehensive diagnostic approach and targeted therapy.

Self-limited giant cell arteritis: The dilemma associated with its diagnosis and treatment.

Giant cell arteritis (GCA) can result in visual loss and other sequelae. An 81-year-old man presented with a one-week history of fever. He had bilateral temporal headache, jaw claudication, tenderness of the temporal arteries and a recent skin rash. A temporal artery biopsy showed typical GCA, but the symptoms were self-limiting. We continued close observation, without administering prednisolone treatment. Five months later, the symptoms did not recur, and prednisolone again was not administered. Our patient presented with an atypical course of GCA that created a clinical dilemma. The final diagnosis was self-limiting GCA.

Untargeted metabolomics analysis reveals the potential mechanism of imatinib-induced skin rash in patients with gastrointestinal stromal tumor.

Imatinib-induced skin rash poses a significant challenge for patients with gastrointestinal stromal tumor, often resulting in treatment interruption or discontinuation and subsequent treatment failure. However, the underlying mechanism of imatinib-induced skin rashes in gastrointestinal stromal tumor patients remains unclear. A total of 51 patients (27 with rash and 24 without rash) were enrolled in our study. Blood samples were collected concomitantly with the onset of clinical manifestations of rashes, and simultaneously collecting clinical relevant information. The imatinib concentration and untargeted metabolomics were performed by ultra-high-performance liquid chromatography-tandem mass spectrometry. There were no significant differences in age, gender, imatinib concentration and white blood cells count between the rash group and the control group. However, the rash group exhibited a higher eosinophil count (P<0.05) and lower lymphocyte count (P<0.05) compared to the control group. Untargeted metabolomics analysis found that 105 metabolites were significantly differentially abundant. The univariate analysis highlighted erucamide, linoleoylcarnitine, and valine betaine as potential predictive markers (AUC≥0.80). Further enriched pathway analysis revealed primary metabolic pathways, including sphingolipid signaling pathway, sphingolipid metabolism, cysteine and methionine metabolism, biosynthesis of unsaturated fatty acids, arginine and proline metabolism, and biosynthesis of amino acids. These findings suggest that the selected differential metabolites could serve as a foundation for the prediction and management of imatinib-induced skin rash in gastrointestinal stromal tumor patients.

Fever with Rash in a Child: Revisited.

Rash and fever are some of the most common chief complaints present in paediatric dermatology emergencies. The spectrum of differential diagnosis is broad, including many different infectious and some non-infectious agents. A systematic approach involving detailed history taking, careful clinical examination along with particular attention to epidemiological features are the most important factors to make a diagnosis. This article reviews the morphological patterns of various causes of fever with rash in children, including infectious as well as non-infectious causes, with special emphasis on the Indian scenario. We intend to highlight the clinical characteristics of each cause, which will not only help make a clinical diagnosis but also distinguish benign versus life-threatening causes of skin rash in febrile paediatric patients and provide early medical intervention.

Early Identification and Management of Patients with Rash on Apalutamide.

Apalutamide is a selective androgen receptor signalling inhibitor that is used in the treatment of prostate cancer. Skin rash is one of the most common adverse events with apalutamide. Although the majority of rash events are grade 1 and 2, the appearance of skin rash during treatment can lead to dose reduction, a pause in treatment or even treatment discontinuation, especially if patients present late when the rash has become severe. This in turn can result in a significant delay or even a permanent discontinuation in the patient's treatment of prostate cancer. As apalutamide is a generally well tolerated and an effective treatment for many men with advanced prostate cancer, it is extremely important to make attempts to prevent skin problems or to manage them at the earliest stage possible. We therefore have developed practical guidance for the management of apalutamide-related rash, including an infographic with recommendations for rash management by grade. Central to this approach is patient education and awareness. Encouraging patients to proactively care for their skin from the start of treatment and informing them of the risk of rash with apalutamide therapy are essential. If the patient observes any skin changes, they should be advised to report it straight away to their cancer care team. Adopting this simple, proactive approach of patient education and increased vigilance from the care team is expected to lead to early identification of rash and subsequent intervention to allow for quicker resolution and enable patients to continue their cancer treatment with a drug that can delay disease progression and increase survival in patients with prostate cancer.

Hydrochlorothiazide-Induced Exfoliative Rash and Sepsis.

Hydrochlorothiazide is a diuretic agent commonly used to treat hypertension, chronic edema from congestive heart failure or cirrhosis, and nephrogenic diabetes insipidus. Diuretics work by increasing urine output and are classified based on the specific renal segments they act on. As with all medications, they are not without their side effects. The most significant and serious include hypovolemia and electrolyte disturbances. Other more rare adverse effects include dermatitis and hypersensitivity reactions. We discuss an 86-year-old male who presented to the emergency room with complaints of lightheadedness and progressive exfoliating rash that began shortly after starting hydrochlorothiazide in an outpatient setting.

COVID-19 Infection Manifesting with Maculopapular Rash: A Case Report.

COVID-19 commonly manifests with respiratory symptoms but is reported to involve other organs including the skin. This is a case of a 58-year-old male diagnosed with mild COVID-19 infection via reverse transcriptase-polymerase chain reaction (RT-PCR) nasopharyngeal swab (NPS). He initially presented with symptoms of fever, cough, colds, sore throat, anosmia, ageusia, myalgia, and diarrhea. Maculopapular cutaneous lesions appeared on the extremities on the 3rd day of illness and were described as pruritic and blanching. The patient was managed conservatively with oral hydration and vitamin supplementation. During home isolation, symptoms were monitored via telemedicine. He recovered and was asymptomatic 36 days from the onset of symptoms. During the early part of the pandemic, further diagnostic testing was challenging due to the restrictions that were implemented. However, careful history, modified physical examination, and monitoring through teleconsultation proved to be very useful. Documenting the course and outcome of COVID-19 patients with skin manifestations would help facilitate timely diagnosis and treatment, as well as anticipate the possible prognosis of patients who present with a similar clinical pattern.

Study on percutaneous penetration of representative cosmetic ingredients in a baby wipe product in an in vitro diaper rash skin model.

Studying percutaneous penetration of various cosmetic ingredients through intact and compromised skin can provide insight on quantitative exposure assessment for baby products intended for diapered skin. We developed an in vitro model (tape-stripped human skin) designed to achieve the Trans-Epidermal Water Loss values measured in babies with various degrees of diaper dermatitis. Six reference compounds showed the impact of physicochemical properties on absorption through this "diaper rash" skin model. Under simulated diaper conditions, dermal absorption of cosmetic ingredients (phenoxyethanol, sodium benzoate, benzyl alcohol, disodium EDTA, and propylene glycol) was different, but <100%. Additionally, the effect of diaper rash on dermal absorption of well-absorbed ingredients (phenoxyethanol, sodium benzoate, and benzyl alcohol) was limited (enhancement of 1.1-1.3), while the enhancement for moderately absorbed compounds (disodium EDTA and propylene glycol) was 1.8-3.3. Absorption via skin with "diaper rash" is specific to individual ingredients and exposure conditions, so a fixed uncertainty factor is not appropriate for safety assessment. The data support that the default 100% dermal absorption commonly used in first-tier risk assessments for diapered skin is conservative. This diaper rash skin model provides a practical tool of estimating absorption of various ingredients in baby products intended for diapered skin.

Psoriasis Vulgaris Masked by Tinea Pedis in Two Unhoused Patients.

Psoriasis is a chronic inflammatory disease characterized by clearly marginated silvery plaques that affect men and women equally. Symptoms can vary among individuals; typically, it presents on the scalp, elbows, and knees. We present two cases of patients initially diagnosed with tinea pedis who showed no improvement with medical treatment. The first patient is an African American male in his 50s who arrived at a free clinic for unhoused persons with lesions to both feet initially diagnosed as tinea pedis. Although the patient was compliant with applying topical formulations of tolnaftate and clotrimazole, there was no discernible improvement in his symptoms and the skin lesions. After a thorough examination of the skin throughout the entire body, the diagnosis of psoriasis was considered. The patient started treatment with steroidal cream with improvement of the symptoms and lesions. The second patient is a Caucasian male in his 20s who also presented initially with complaints of a dry, intensely pruritic, and scaly rash on the dorsum of both his feet, as well as in between the digits of his feet for which an initial diagnosis of tinea pedis was also made. The patient remained non-compliant with treatment and, after reevaluation of his lesions along with an extensive survey of his body, was deemed to have psoriasis and prescribed topical hydrocortisone. The patient continued to remain non-compliant with his therapeutic regimen and subsequently developed cellulitis which is yet to resolve with treatment.

Parvovirus B19 Infection in Adults: A Case Series.

Parvovirus B19 infection, typically associated with erythema infectiosum in children, presents variably in adults, often leading to misdiagnosis. This case series describes three adult patients diagnosed with parvovirus B19 infection in an internal medicine outpatient clinic in March 2024. Symptoms included fatigue, joint pain, swelling, and skin rash, with misdiagnoses including early rheumatoid arthritis. The diagnosis was confirmed via positive parvovirus antibodies and polymerase chain reaction (PCR). All patients received supportive care, and symptoms resolved within an average of 18 days. This series underscores the need for heightened clinical suspicion and timely serological testing for parvovirus B19 in adults presenting with flu-like symptoms, joint pain, and rash, especially during mini-outbreaks and following contact with infected children.

Resolution of Stubborn Monkeypox With Tecovirimat in an HIV Patient.

A 40-year-old male with a history of human immunodeficiency virus (HIV) (CD4 absolute count 57 cells/uL) presented to the Emergency Department complaining of large, swollen abscesses on his face, right hand, and feet. He reported the outbreak of the lesions occurred four months ago and coincided with a week-long episode of diarrhea, rectal pain, and perirectal and inguinal lymphadenopathy. Physical exam was significant for a full-thickness fluid collection on the sole of the right foot, a plantar abscess on the left foot, an open, crusted ulcer on the left fifth finger, and several large, crusted lesions on the face. Of note, the patient was seen at a nearby hospital three months prior, underwent a biopsy that showed non-variola orthopoxvirus DNA via real-time polymerase chain reaction (PCR), and was diagnosed with monkeypox at that time. He was advised to pick up tecovirimat treatment from the Department of Health but stated it was unavailable when he arrived and never took it. On this admission, the lesion was again biopsied and detected non-variola orthopoxvirus DNA by real-time PCR. The patient was discharged on 600 mg tecovirimat orally twice daily for 14 days. At the 14-day follow-up, the patient's lesions had completely fallen off and were no longer painful.

Persistent Pruritic Linear Streaks of Adult-Onset Still's Disease: Reconsidering the Yamaguchi Criteria.

Objective Adult-onset Still's disease (AOSD) is a rare orphan disease, the diagnosis of which remains challenging. This study aimed to identify additional clues for establishing early diagnosis beyond the existing criteria. Methods A retrospective longitudinal cohort study was conducted at two community hospitals in Japan between March 2012 and December 2022. The clinical characteristics and medical histories of patients with AOSD were extracted from the clinical records. The primary outcome was to identify the key manifestations of AOSD for an early diagnosis beyond the existing criteria. Results Twenty-one patients (mean age, 58 years) were included in the study. Fever was the first symptom in 13 out of 21 patients (62%). Six out of 21 patients (29%) presented with a pruritic rash only, while two out of 21 (10%) initially presented with a sore throat. All patients visited more than one medical institution. The median time to reach a correct diagnosis was 41 days (IQR 19-138). Nineteen out of 20 patients (95%) exhibited a pruritic rash, identified as persistent pruritic linear streaks, with a median duration of 21 days (IQR 12-64) before the diagnosis of AOSD as a cutaneous manifestation. Conclusions Persistent pruritic linear streaks were a key feature in the context of an early diagnosis of AOSD, offering an option for reconsidering and revising the existing classification criteria.
