Clin Exp Pediatr. 2016;59(Suppl 1):S107-S111.   Published online November 30, 2016

Sex cord tumors with annular tubules are known to originate from the sex cord of embryonic gonads that synthesize Sertoli cells, Leydig cells, granulosa cells, and theca cells of the ovarian stroma, while ovarian small cell carcinoma of the hypercalcemic type is a type of neuroendocrine tumor. Both these tumors are uncommon, potentially malignant neoplasms in children. We report the...

Clin Exp Pediatr. 2005;48(2):208-211.   Published online February 15, 2005
Primary lung cancer is unusual in children; the squamous cell variant is extremely rare. Lung cancer is classified by histologic types into small-cell lung cancer, non-small cell lung caner, carcinoid, mucoepidermoid carcinoma, and adenoid cystic carcinoma. Furthermore, non-small cell lung cancer is subclassified into adenocarcinoma, large-cell carcinoma, and squamous cell carcinoma. The incidence of lung cancer is influenced by smoking,...

Clin Exp Pediatr. 1995;38(2):195-206.   Published online February 15, 1995
Purpose : Surgical excision has been the primary treatment for hepatoblastoma and hepatocellular carcinoma. However, at presentation, only one third of such tumors are surgically resectable. Without operation, the disease is fatal. Therefore, neoadjuvant chemotherapy has been introduced for conversion of the unresectable tumors into the resectable ones. We studied th e effects of chemotherapy for hepatic malignancy in children. Methods...
