An 8-year-old girl was seen in our outpatient clinic with a history of an angiomatous plaque on the chest since birth. She had complained of pain at the site of the lesion for 1 month. Histopathologic examination and immunohistochemical analysis led to the diagnosis of glomangioma, a rare congenital plaquelike glomus tumor. We review the literature and discuss the clinical presentation and evolution of this rare entity.

Lichen striatus (LS) is a benign, self-limited, linear, inflammatory dermatosis of unknown etiology that usually affects children. We analyzed 89 cases in regard to age of appearance, sex, race, symptoms, seasonal incidence, localization of lesions and affected side of the body, and presence of atopy. Lesions predominated on the inferior limbs, with no preponderance of any age, and were asymptomatic in the majority of the instances. There was no difference in the incidence of LS in regard to the season of the year. A possible association of lichen sclerosus with atopy and pruritus was observed.

Primary palmar hyperhidrosis in children and adolescents may be severe enough to affect school and physical activities, causing emotional problems, stress in the patient's life, and a compromised quality of life. Nine patients with palmar hyperhidrosis underwent treatment with botulinum A. Before the session, and in the 1-, 3-, 6-, 9-, and 12-month post-session follow-ups, the patients were administered the Minor test, gravimetry, the Scales of Frequency and Severity, and the Questionnaire of Quality of Life. The mean age was 11 years, with seven girls and two boys. Each patient was administered at least one treatment of botulinum toxin in the palm of the hands (75-150 U for palm), with the mean number of sessions 2.2 (range: 1-4). All sessions in the patients resulted in drying of the hands, with a mean duration of effect of 7 months. Botulinum toxin A controls excessive sweat in the palms of children and adolescents who have primary palmar hyperhidrosis, with an improvement in the quality of life. The therapy is safe and effective in this pediatric group and can be considered before surgical interventions.

Indolent leg ulcers are a rare complication found in patients with hereditary spherocytosis. We report a 13-year-old girl with hereditary spherocytosis who developed a chronic painful ulcer on the medial malleolus. All other etiologies were ruled out. Nine months after splenectomy the ulcer healed completely and the symptoms disappeared. We discuss and review this unusual entity in children.
