- Cloacogenic polyps are rare inflammatory lesions occurring around the anal transitional zone and in the lower rectum which can mimic neoplasia. They should be given diagnostic consideration in patients presenting with symptoms of rectal bleeding, tenesmus, and altered bowel habits.
- Duodenal perforation secondary to blunt abdominal trauma in children is rare and usually associated with delays in diagnosis and surgical intervention. The authors encountered such a case in a 12-year-old boy owing to his falling over the handlebar of a bicycle. Imaging examination showed that there was a perforation over the fourth portion of the duodenum without concomitant injuries. Using a 5-port transperitoneal laparoscopic technique, primary closure of the perforation was successfully performed at 6 hours after the impact.
- Breast masses presenting in adolescent boys are rare and are almost uniformly owing to gynecomastia. Although surgical referral for breast masses in adolescent boys is common, intervention is typically for cosmesis. We report the case of a 14-year-old boy who presented with an enlarging unilateral breast mass, which was found to be owing to an intraductal papilloma at the time of surgical excision.
- We report the case of a 15-year-old girl diagnosed with mucinous cystadenoma 3 years after ovarian-sparing surgery for a mature teratoma located in the same ovary. Ovarian teratoma is the most common ovarian neoplasm in children, whereas mucinous cystadenoma is extremely rare during childhood.
- The most common renal neoplasms in the second decade of life are renal cell carcinomas and Wilms' tumors. Glomus tumors arising in the kidney are rare. We report an adolescent with a benign renal glomus tumor excised by wedge resection. Nephron-sparing surgery is the therapy of choice for children with benign renal tumors. Glomus tumor should be considered in the differential diagnosis of a renal mass in a young patient.
- Congenital cystic adenomatoid malformation, a rare developmental, hamartomatous abnormality of the lung, usually is unilateral, is localized, and presents in early infancy. Delayed occurrence in older children and multilobar involvement are rare. We describe a case of congenital cystic adenomatoid malformation type 1 with multilobar involvement, associated emphysema, and coexistent tracheobronchopathia osteochondroplastica in an adolescent girl for whom the correct diagnosis was achieved only on histologic examination.
- Laparoscopic approaches to giant ovarian cysts, particularly in adolescents, have critical management concerns as follows: risk of malignancy, risk of cyst rupture, and limited working space. A 15-year-old girl presented with a giant (>25 cm) ovarian serous cyst adenoma containing 7 L of fluid. At open laparoscopy, a giant, entirely cystic, smooth mass originating from the right ovary and lying between the symphysis and the xiphoid was observed. After intraabdominal fluid aspiration, open conservative cystectomy was performed, avoiding spillage.
- A 12-year-old boy presented with a weight of 136 kg and a history of progressive vision loss associated with unremitting pseudotumor cerebri requiring bilateral optic nerve sheath decompression. He underwent laparoscopic Roux-en-Y gastric bypass (RYGBP) without complication. At 36 months post-RYGBP, he has grown 5 cm since the time of surgery, his weight is 6.8 kg above his postoperative nadir weight of 68.2 kg, and his visual acuity has improved with OD 20/100 (preoperative, 20/200) and OS 20/70 (preoperative, 20/100).
