Retroperitoneal Teratoma in an Infant

Abstract

Abstract:Retroperitoneal teratoma in infancy is exceedingly rare. Progressive enlargement of the abdomen and the presence of an intra-abdominal mass is the most common clinical feature. They constitute third most frequent type of retroperitoneal neoplasm seen in infant and children after Wilm's tumor and neuroblastoma. We report here a case of giant retroperitoneal teratoma in an infant. A 5 month old female child was admitted with complain of abdominal distension. Abdominal CT scan revealed a tumor suggestive of retroperitoneal teratoma. Intraoperative finding revealed that tumor was compressing the atrophic right kidney. Resection of tumor with right nephrectomy was done successfully.

Retroperitoneal Teratoma in Infancy; Report of an Unusual Entity

“…Important features suggesting benign nature on CT scan includes homogeneity, cyst formation, fat density, and calcification [15]. Fat fluid level and chemical shift between fat and fluid are pathognomonic, however fatfluid level can be seen in well differentiated liposarcomas of retroperitoneum.…”

Supra Renal Teratoma- A Case Report

“…Retroperitoneal teratomas are mostly asymptomatic and as the tumor grows, may compress the surrounding structures resulting in colicky abdominal pain, intestinal obstruction or peritonitis. The usual presentation is a palpable mass or distension of abdomen [14] . Our patient presented with abdominal mass on left side with low grade fever, no other pressure symptoms observed.…”

“…Increased serum alpha-feto protein level indicates recurrence of tumor in follow up [14] .After ultrasonogram of abdomen, we did CECT abdomen to delineate the mass. Alpha feto protein and Beta HCG levels were normal in our case.…”

“…Chances of malignancy are uncommon in retroperitoneal teratoma and non mutilating excision is possible, hence complete surgical excision is the treatment of choice [14,20] . Prognosis is generally good after complete resection of the tumor, although malignant recurrence were also reported in few cases.…”

Retroperitoneal Mature Cystic Teratoma in a 3-month-old Infant: A Case Report and Literature Review

“…Most common sites of GCT are gonadal locations; ovarian or testicular. [1,2] Although extragonadal GCT is more frequently encountered in children, the majority are located in the sacrococcygeal region. [3] They are also seen in the mediastinum, especially the anterior mediastinum, head and neck, particularly in the pineal gland.…”
