Background . Chronic spontaneous urticaria (CSU) is autoimmune in nature and associated with thyroid autoimmunity (TA), but evidence on relation to CSU progression prognosis limited. We evaluated whether TA are correlated disease severity, therapeutic response, time remission establish an association between characteristics linked autoantibody. Methods Medical records of patients diagnosed attending outpatient dermatology clinic at a university-based hospital from 2013 2017 were...

ABSTRACT We report three cases of contact allergy to a mislabelled hair dye product. A product labelled as p ‐phenylenediamine‐free has been found contain ‐phenylenediamine by chemical analysis at the level above limits allowed in

Radiation-induced alopecia after fluoroscopically guided procedures is becoming more common due to an increasing use of endovascular procedures. It characterized by geometric shapes nonscarring related the area radiation. We report a case 46-year-old man presenting with asymptomatic, sharply demarcated rectangular, alopecic patch on occipital scalp following cerebral angiography fistula embolization under fluoroscopy. His presentations were compatible radiation-induced alopecia. Herein, we...

Abstract Background A recent report suggested potential of high‐intensity focused ultrasound in improving UVB‐induced hyperpigmentation patients with Fitzpatrick skin type IV, but reports regarding its efficacy other hyperpigmented conditions including melasma are lacking. Objectives To investigate and safety for the treatment Asians. Methods Each side face 25 was randomized to receive 3‐monthly sessions or serve as control.

Methotrexate-related lymphoproliferative disorders (MTX-LPDs) are immunodeficiency diseases following methotrexate (MTX) administration, mainly occurring in rheumatoid arthritis patients. Although uncommon, MTX-LPDs have been reported some patients with psoriasis, dermatomyositis, and cutaneous T-cell lymphoma (CTCL) who received MTX. Granulomatous mycosis fungoides (GMF) is a rare subtype of lymphoma, where MTX one the treatment options recalcitrant cases. Herein, we report case 72-year-old...

Background: Co-trimoxazole has been reported as a common culprit drug for various cutaneous adverse reactions (CADRs). However, information on genotypic and phenotypic characteristics is still limited. We aimed to study clinical characteristics, genetic suitability, laboratory findings, treatment outcomes in patients with co-trimoxazole-induced CADR determine variables associated severe (SCARs). Methods: The medical records of all diagnosed during October 2015 2021 were reviewed. Clinical...

Background and Objectives Microfocused ultrasound with visualization (MFU‐V) has been approved for the treatment of skin laxity on several areas including eyebrows, neck, submental area. This study aims to determine efficacy MFU‐V abdominal using two different protocols. Study Design/Materials Methods Thirty female patients were enrolled. Each side abdomen was randomly assigned receive a single session single‐plane (4.5 mm) or dual‐plane 3.0 mm). Improvement scores (0–10) by blinded...

D-penicillamine is used as the mainstay of chelation therapy for Wilson's disease and heavy metal intoxication. itself has been noted to cause several systemic side effects well symptoms related skin. Common cutaneous such acute hypersensitivity reactions, elastic fiber abnormalities, bullous diseases have occasionally described. Herein, we report a case 23-year-old Thai female with gold intoxication who developed Stevens-Johnson syndrome (SJS) following treatment D-penicillamine. To our...

Background . Intravascular large B-cell lymphoma (IVLBCL) is a variant of extranodal diffuse (DLBCL), characterized by the presence B-lymphoma cell in lumina small blood vessels or capillaries. Due to its extremely variable clinical manifestations, IVLBCL typically results delayed diagnosis and poor disease prognosis. Skin biopsy, particularly random skin has shown potential role IVLBCL. However, information clinicopathological features patients with diagnosed biopsy limited. Objectives To...

Background and Objectives Non‐invasive skin tightening devices have become a safe non‐invasive treatment for patients with laxity of the upper arm. The efficacy microfocused ultrasound visualization (MFU‐V) in had been demonstrated several studies. This study aimed to evaluate safety MFU‐V treating arm using different protocols. Study Design/Materials Methods Thirty were enrolled. Patients randomly assigned receive single‐plane (4 MHz/4.5 mm transducer) on one dual‐plane 7 MHz/3.0...

The use of methotrexate-acitretin (MTX-ACI) combination therapy in treating psoriasis has been limited due to concerns related hepatic fibrosis. However, vitro evidence revealed a protective effect acitretin methotrexate (MTX)-induced liver fibrosis.This study aimed compare the real-life incidence fibrosis patients with receiving MTX-ACI and MTX monotherapy investigate factors associated MTX-exposed patients.A retrospective cohort was conducted based on registry containing data who were...

Background: Scalp psoriasis is usually refractory to treatment. Excimer devices have been proved be a promising therapeutic option in psoriasis. Greater efficacy of phototherapy can achieved by concurrent use coal tar derivatives. Objective: We aimed compare and safety between 308-nm excimer lamp monotherapy combination 10% liquor carbonis detergens the treatment scalp Methods: In this randomized, evaluator-blinded, prospective, comparative study, 30 patients with received either or twice...

Psoriasis is a chronic, recurrent, and relatively common inflammatory dermatologic condition, which demonstrates various clinical manifestations including hair loss. It was once believed that alopecia not presentation of scalp psoriasis, but it now widely accepted psoriatic exists. Although the majority patients get regrowth, can potentially lead to permanent Herein, we report case 26-year-old female patient with systemic lupus erythematosus who presented loss nonpruritic scaly plaques on...

Lichen planopilaris is a rare inflammatory condition that also known as follicular lichen planus. Although the commonly affects scalp, it sometimes involves other regions of body with variety clinical presentations. The involvement beyond scalp considered to be generalized nature disease process. In this report, we present case planus in 34-year-old Thai female presenting comedone-like lesions on trunk and extremities well scarring alopecia scalp. Dermoscopic features were discussed.

Panitumumab is a recombinant, fully humanized immunoglobulin G 2 monoclonal antibody targeting the epidermal growth factor receptor (EGFR).It approved for first-and second-line treatment of advanced wild-type KRAS colorectal cancer.Although common cutaneous side effects include acneiform dermatitis, folliculitis, and xerosis, ocular toxicities have occasionally been reported.Herein, we report case an 81-year-old Thai female with chemorefractory stage sigmoid colon cancer who developed...
