The authors report the electron microscopic features of gingival granular cell tumors (GGCT) resected from two newborn girls. Although origin from odontogenic epithelium has been proposed, the ultrastructural findings strongly support histogenesis from stroma (mesenchymal) cells. Tissue assay for estrogen receptors was negative, but considering the marked(More)
The clinical and pathologic features of 24 gingival granular cell tumors in newborns are reviewed. These tumors occurred exclusively in females and were localized on the anterior alveolar ridge (maxilla: 14; mandible: 9); the gingiva overlying future canine and lateral incisor teeth was most frequently involved. Follow-up data for 15 patients (average(More)
This study was designed to assess whether development of the central nervous system (CNS) is delayed in victims of the sudden infant death syndrome (SIDS). We selected the parameter of myelination because it is a continuously changing and readily accessible marker of CNS development in the SIDS age-range. We assessed myelination blindly in 61 SIDS and 89(More)
A primary bronchial tumor was diagnosed in six children younger than age 12 years. These cases include four bronchial carcinoids, a low-grade mucoepidermoid carcinoma, and a granular cell tumor ("myoblastoma"). Lobar or segmental resection was performed in each case and remains the treatment of choice. The most common bronchial tumors in childhood are(More)
