ABSTRACT
Background@#Tinea capitis, a superficial dermatomycosis, is caused by a dermatophyte infection on the scalp and hair. Recently, the number of adult patients with tinea capitis have been increasing; therefore, the clinical and mycological features of tinea capitis may be different from those of previous reports. However, only a few studies on adult tinea capitis have been conducted in Korea. Objective: This study aimed to analyze the clinical and mycological features of Korean adult patients with tinea capitis. @*Methods@#A retrospective review of 61 adult patients with tinea capitis was conducted. Clinical features including age, sex, clinical type, and treatment outcome were obtained from medical records and images. The mycological features, including the result of KOH smear and fungal culture, were also analyzed. @*Results@#The mean onset age was 61.3 years, and the male-to-female ratio was 1:4.1. Two patients (3.3%) had a family history of developing the same symptoms, and 17 (27.9%) had a history of close contact with animals. The most predilection site was the vertex, followed by the frontal and parietal areas. Microsporum canis was cultured in 66.7% patients, and Trichophyton rubrum was cultured in 28.6% patients. The number of adult patients with tinea capitis has been increasing constantly. The proportion of patients infected by T. rubrum has been increasing since 2000. Of the 51 patients who received treatments, 42 showed improvements. No significant difference was observed between patients treated with terbinafine and itraconazole. @*Conclusion@#This is the large-scale study that analyzed the clinical and mycological features of Korean adult patients with tinea capitis.
ABSTRACT
Hereditary hemorrhagic telangiectasia (HHT), also known as Osler–Weber–Rendu syndrome, is a rare autosomal dominant genetic disorder that results in vascular malformation in the skin, mucous membrane, and other internal organs, such as the gastrointestinal tract, lung, liver, and brain. A 49-year-old man presented with purpuric punctate, spider-like telangiectasia on the face, hands, and fingers. He had episodes of recurrent nasal bleeding. The family members of the patient had similar events of recurrent nasal bleeding and cutaneous telangiectasia. Abdominal computed tomography revealed multiple arteriovenous malformations and cysts in the liver. Gastroendoscopy and colonoscopy showed angiodysplasia of the fundus of the stomach and mucous membrane of the colon. Histopathologic examination revealed dilated vessels lined with flat endothelial cells in the dermis. We report herein the case of HTT because it is rare and significant for differential diagnosis.
