- Most appendiceal carcinoids (ACs) in children present without lymph node metastasis. Lymph node metastasis is rarely present when primary tumor diameter exceeds 1 cm. We present the extraordinary case of an AC with a primary tumor diameter of 0.7 cm and infiltration of the mesentery, as well as 1 positive lymph node of the mesentery in a 14-year-old boy. Besides adding a rare case, we review the data published in the current literature on AC with lymph node metastasis in children and summarize up-to-date guidelines for diagnostic workup, therapy, and follow-up.
- This case report describes a unique variant of a duodenal duplication cyst in an 8-year-old boy who had recurrent episodes of upper abdominal pain. Imaging revealed a stone-containing cyst near the biliaropancreatic ducts and concomitant hydrops of the gallbladder. Open transduodenal marsupialization of the cyst and resection of the inflamed gallbladder were performed. Further episodes of pancreatitis did not occur for a follow-up of 2 years.
- We report on a case of nodular periorchitis, an uncommon perifunicular mass in a 13-year-old adolescent accompanied by contralateral hydrocele. Nodular periorchitis is a rare, fibroproliferative, benign mesenchymal neoplasm of the paratesticular tissues of the scrotum with a low risk for recurrence. Testis-preserving surgery is the treatment of choice.
- The authors report on an 8-year-old boy with unilateral left-sided Leydig cell tumor. After enucleation of the tumor, endocrine disturbances resolved. Long-time follow-up for more than 7 years was characterized by growth-arrest of the affected gonad and the unchanged appearance of a circumscribed hypoechogenic residual lesion within the testis.
