Melanoma in children and the use of sentinel lymph node biopsy.

Background: The rarity of pediatric melanoma prompted our review of sentinel lymph node biopsy (SLNB) and associated prognosis.

Methods: A chart review from 1989 to 2004 revealed 12 cases of cutaneous melanoma. Variables analyzed included demographics, site, histology, tumor characteristics, nodal status, and distant metastasis (TMN status), SLNB and/or therapeutic lymph node dissection (TLND), adjuvant treatment, disease-free survival, and overall survival.

Asynchronous bilateral ovarian torsion.

Background: Pediatric ovarian torsion (OT) is a serious condition, especially in cases of asynchronous bilateral ovarian torsion (ABOT). The authors sought to evaluate the predisposing factors for ABOT and to evaluate the most appropriate treatment for ovarian torsion.

Methods: The authors retrospectively reviewed the charts of patients with ovarian torsion between 1980 and 2002.

Spontaneous pneumomediastinum: are we overinvestigating?

Background: Spontaneous pneumomediastinum (SPM) is uncommon in pediatrics. Because of the growing concern about the risks of radiation in children, the authors analyzed whether an extensive radiologic workup influences management and outcome.

Methods: In a retrospective study from 1991 to 2003, 53 patients were diagnosed with SPM.

Unilobar congenital pulmonary lymphangiectasis mimicking congenital lobar emphysema: an underestimated presentation?

Background: Congenital lobar emphysema (CLE) is characterized by unilobar alveolar distension secondary to bronchomalacia or absent cartilage. In contrast, congenital pulmonary lymphangiectasis (CPL) is defined as distended lymphatics in the bronchovascular bundle, in the interlobular septa, and in the subpleural space. Little information is available regarding the radiologic presentation of CLE as it correlates with histological diagnosis.
