Unusual K-wire migration.

The authors report a case of intra-abdominal migration of a Kirschner wire from the left hip to the right lobe of the liver in a 5-year-old child. The wire was used for stabilization of the left hip after open reduction for neglected unreduced congenital dislocation of the left hip. The migrated wire was removed by laparotomy. Surprisingly, no injury was noted to any intervening abdominal structure intra-operatively. This unusual migration of a Kirschner wire into a child's liver has not been reported previously.

Acquired ileal atresia in infancy: report of two cases.

Two infants, aged 3 months and 4 months, with acquired ileal atresia in the distal ileum are described. Both of them presented with features of intestinal obstruction following a diarrhoeal episode. In both patients the time interval between the onset of symptoms and detection of atresia at surgery was very short, i.e. 2 weeks. In our opinion, strangulation with subsequent resorption of gangrenous gut could have been the underlying mechanism in both patients. However, a short interval between initiation of symptomatology and detection of atresia prompted us to postulate a thromboembolic phenomenon as the cause of these lesions. While in one patient intussusception was noted on sonography, in the other there was no clear-cut aetiology present except for a high-lying caecum with a long mesentery that might have led to volvulus. We have reviewed the pertinent literature of this very rare sequela of gut inflammation.

Infected primary intramuscular echinococcosis of thigh.

An unusual case of infected primary echinococcosis involving quadriceps muscles of the thigh and presenting as a cystic mass in a child is being reported. The diagnosis was made preoperatively with ultrasound examination and serology. After a cover of medical treatment the cyst was excised. Various clinical possibilities and management strategies are discussed.

A rare presentation of abortive epispadiac urethral duplication and vanishing midurethra.

We report a 4-year-old boy with a hitherto undescribed case of abortive epispadiac duplication of the urethra presenting as a blind-ending penopubic sinus proximally and a mucosa-lined groove overlying the glanular corona distally but with absent midurethra. The patient was treated for cosmetic reasons with good results. A plausible embryological genesis of this defect is discussed.

Thoracolumbar rachipagus parasite.

A rare example of rachipagus conjoint parasitic twinning in a newborn girl is described. A lipomatous mass with an attached hind limb (with fused feet) and a rudimentary vertebral arch were found adherent to the dorsal vertebral arches of the autosite in the thoracolumbar region. There was a clear cleavage plane between the autosite and the parasite. Microscopic sections of the excised specimen showed gut only. The autosite had no other congenital anomalies except for spina bifida in the thoracolumbar region with unfolding of the underlying cord. In the absence of underlying life-threatening anomalies, surgical excision of the parasite and treatment of the associated anomalies of the autosite is known to offer gratifying results.

"Pouch colon patch graft"--an alternative treatment for congenital short colon.

A patch graft of the pouch colon over the pulled-through ileum in a patient with long-length pouch colon (in whom the entire colon was replaced by a pouch that communicated with the urinary bladder) was tried with good results for the first time. At follow-up the patient was found to have normal bowel patterns and weight gain. Though colon patch grafts have been widely used in patients with total colonic aganglionosis, they have not been tried for the short colon. The authors discuss the clinical setting in which the procedure may prove useful in patients with pouch colon and why these patch grafts may yield comparable or even better results in patients with pouch colon compared with those with total colonic aganglionosis.

Papillary carcinoma thyroid: FNAC diagnosis.

Thyroid carcinoma in children is currently assuming greater importance due to increase incidence in the recent times. In carcinoma thyroid, the age at the time of diagnosis is an important prognostic factor and children in particular are considered to have an excellent prognosis. We came across 3 cases of papillary carcinoma thyroid involving both the lobes and having lymph node metastasis in children, the youngest being 4 years of age at the time of diagnosis. All these cases were diagnosed on aspiration cytology.

Pancreatoblastoma (infantile pancreatic carcinoma)--a case report.

Pancreatoblastoma or infantile pancreatic carcinoma is a rare pancreatic tumor with distinct acinar and squamoid cell differentiation that generally affects infants and young children. Ultrasound and CT scan may be useful but preoperative diagnosis is often quite difficult. The outcome is generally favourable. A such case of 10 years old boy with an abdominal mass is being presented.

Aniridia and Wilm's tumor.

Aniridia (absence of iris) is a congenital, bilateral, uncommon panocular disorder. Whereas the occurrence of aniridia in the general population is 1:50000, it is present in about 1 in 70 patients with Wilm's tumor. This aniridia is sporadic and Wilm's tumor in these cases presents at an unusually early age. Aniridia was present in two cases out of 60 cases of Wilm's tumor operated at PGIMS, Rohtak. Both cases presented below two years of age. The recognition of a child with sporadic aniridia should alert to the increased risk of development of Wilm's tumor.

Perineal accessory scrotum.

A boy with perineal accessory scrotum but without any other congenital anomaly is being described. He presented with a rugose skin tag on a midline perineal mound and the diagnosis could be confirmed by the histological findings of subcutaneous smooth muscles. Other reports of perineal scrota have been reviewed and a simple classification has been proposed for such cases, based on the appearance of the accessory scrotum and the associated anomalies.

Advanced sigmoid carcinoma colon.

A 13-year-old female child diagnosed initially as having tuberculosis was subsequently found to have adenocarcinoma colon with secondaries in ovaries and omentum, and proved to be mucinous carcinoma on biopsy. Patient received chemotherapy (FAM) regimen without any relief even 2 months after surgery.

Teratomas in infancy and childhood.

A 10-year-experience with 42 cases of teratomas in paediatric age group is presented. The commonest type of teratoma was sacrococcygeal followed by ovarian and retroperitoneal teratomas. An analysis of clinical profile, malignant potential, management, prognostic factors and follow up is discussed with review of literature.

Pseudoexstrophy in a female child.

A six-year-old female patient presenting with a swelling in the infraumbilical part of the abdomen, bulging out on straining, was diagnosed to have pseudoexstrophy bladder. The urinary tract was normal. The patient had bifid clitoris. There was no other associated malformation. Surgical repair of abdominal wall defect was done successfully. A new classification of exstrophy variants is proposed.

Pancreatoblastoma.

Pancreatoblastoma is an extremely rare pancreatic tumor in childhood, comprising 0.5% of pancreatic non endocrine tumors. Just over 50 cases have been reported in the literature till 1997. A 10 year-old male child presented with mass abdomen of 9 months duration. USG and CT abdomen showed a large mixed density lobulated mass in abdomen anterior to, and displacing down the portal vein and splenic veins. Exploratory laparotomy revealed a large mass, arising from body and tail of pancreas, not infiltrating the adjacent structures. Complete excision of the mass along with removal of body and tail of pancreas was done. The histopathological examination revealed pancreatoblastoma. He is well without any evidence of disease 6 months after the operation. To the best of our knowledge this is the first case of pancreatoblastoma with a large size (25 x 20 x 15 cm,) weight 2.5 kg, which was localized and where complete excision was possible. The largest size reported in the literature reviews has been around 15 cm. The literature review confirms that an aggressive surgical attack on resectable pancreatoblastoma may often be curative. The role of adjuvant chemotherapy or radiotherapy is still under discussion due to small number of patients treated as yet.
