Infantile hemangioma (IH) usually presents solely as a cutaneous manifestation, and rarely accompanies diverse anomalies such as spinal dysraphism. A 2-month-old girl presented with IH on her lumbar skin as a coin-sized red plaque with adjacent depressed skin and a child-palm-sized red plaque on her left ankle since birth. Considering the coexistence of IH and depressed skin on the midline in her lumbosacral area, magnetic resonance imaging of her spine was performed, which showed intraspinal/dermal vascular tumors with spina bifida occulta at the 12th thoracic vertebrae level. Furthermore, no neurologic deficits were observed. She has been taking oral propranolol with topical timolol to prevent neural complications and the lesions clinically improved. However, additional surgery for the intraspinal lesions was considered due to urination/defecation abnormalities since she was 13 months of age. In cases of midline IH, particularly with additional skin lesions, appropriate imaging studies to identify accompanying anomalies should be performed, and referrals to neurosurgical specialists should be considered.

Nevus comedonicus is a very rare skin disorder characterized by the presence of comedo-like dilated pores with keratinous plugs, rarely resulting in painful recurrent inflammatory nodules or cysts. It presents as localized or extensive form. It displays unilaterally or bilaterally segmental distribution. Histopathologically, it is characterized by keratin-filled epidermal invagination with bulbous proliferation of keratinocytes. The condition may be caused by fibroblast growth factor receptor 2 mutation. Although it may be controlled by a variety of therapeutic modalities, it is difficult to achieve complete resolution. We report a case of extensive nevus comedonicus with inflammatory nodules and cysts controlled with adalimumab.

BACKGROUND: Tinea capitis is a contagious fungal infection that occurs predominantly in childhood. Although its incidence has declined, its epidemiological and mycological characteristics are continue to evolve. OBJECTIVE: To assess changes in the epidemiological and mycological characteristics of tinea capitis in teenage patients in Southeastern Korea. METHODS: We retrospectively investigated epidemiological and mycological characteristics of 202 teenage patients with tinea capitis who visited Kyungpook National University Hospital and the Catholic Skin Disease Clinic from 1989–2018. RESULTS: Of 202 patients, 177 patients showed KOH-positivity. Dermatophytes were cultured from 157 patients. The annual incidence of tinea capitis ranged from 0 to 30 between 1989 and 2018. Of 202 patients, 153 patients (75.74%) were male and 49 patients (24.26%) were female. The ratio of male to female was 1:0.32. For seasonal distribution, 78 patients (38.61%) visited our hospital in winter, 59 patients (29.21%) visited in spring, 35 patients (17.33%) visited in fall, and 30 patients (14.85%) visited in summer. Microsporum canis was the most common dermatophyte (44.06%) isolated from tinea capitis. Trichophyton tonsurans was the second most common dermatophyte (26.73%). For inhabitancy distribution, 151 patients (74.75%) lived in urban areas and 51 (25.25%) lived in rural areas. CONCLUSION The epidemiological characteristics of teenage patients with tinea capitis were distinct from those of adults in annual incidence, sexual distribution and isolated dermatophytes. Trichophyton tonsurans was the main causative organism of tinea capitis in recent 10 years. These results are useful for the targeted treatment and prevention of tinea capitis.
