IMPORTANCE Noncongenital immature teratomas in the head and neck are extremely rare, and to our knowledge have not previously been reported in the maxillary sinus of a pediatric patient. OBSERVATIONS Teratomas are neoplasms that contain tissue from more than 1 embryonic cell layer that is foreign to the location where they arise and are most commonly found in the sacrococcygeal and gonadal re...

INTRODUCTION Fetal tumors are relatively rare and the early prenatal diagnosis enables the prediction of possible complications and decision for appropriate treatment. This paper deals with the role of ultrasonography and magnetic resonance imaging in the early prenatal diagnosis of sacrococcygeal teratoma. CASE REPORT A 21-year-old primigravida was found to have a large sacrococcygeal tumor ...

Teratomas are the most commonly diagnosed germ cell tumors and occur primarily in testes and ovaries. Platinum-based therapy followed by surgical resection of the residual lesion is generally the recommended treatment. In contrast, immature uterine teratomas are rare, with few cases reported in the literature. Moreover, there is no standard treatment for these tumors. Non-puerperal uterine inve...

Cystic pancreatic tumors are rare in children and the immature cystic teratoma of the pancreas is even rarer. A review of the world literature shows 18 documented cases involving all the age groups. The preoperative evaluation of this lesion is rather questionable, with definitive diagnosis taking place intraoperatively. We report the 19(th) case, in a 5-month-old male child. The clinical prese...

We present the case of a 26-year-old man with a bland medical history, who presented to the general practitioner because of severe cough and dyspnea. The chest X-ray revealed a massive organ-displacing tumor in the right chest not delineable from the mediastinum. The subsequent needle core biopsy was diagnostic for a mixed germ cell tumor comprising immature teratoma and seminoma. After an init...

reduction deformities, unilateral bone hyperplasias and digital lengthening have also been described(l,2,4,5). In the present case, the unusual feature found is lengthening of femur, tibia and fibula on right side. Right lower limb was 7 cm longer than the left side. Skeletal changes in this condition are secondary to external pressure and erosion, stimulation or inhibition of epiphyseal longit...

Congenital teratomas occur in extragonadal locations, the commonest site being the sacrococcygeal region. This report describes a rare case of antenatally detected, large, immature retroperitoneal teratoma. The diagnostic and therapeutic challenges of dealing with such a case have been discussed and the relevant literature reviewed. The recurrence of the tumor after gross surgical removal indic...

Teratomas are infrequent germ cell tumors of childhood. They may arise from any organ but the majority are found in the ovary, testis, sacrococcygeal region and mediastinum. Gastric teratoma is rare, accounting for less than 1% of all teratomas (1–3). Immature teratomas are pathologically distinct from the benign and malignant teratomas with their embryonic-appearing neuroglial and neuroepithel...
