Variable Potential

Immature ovarian teratomas are rare ovarian germ cell tumors associated with a variable potential of distant metastasis. The acquisition of mature phenotypes upon post-treatment recurrence of immature teratomas has been previously described. In this study, we report, for the first time, a rare case of a recurrent ovarian immature teratoma with mature deposits in the small bowel. An incidental pelvi-abdominal mass was identified in a 30-year-old pregnant patient during antenatal ultrasonography. The mass, which was resected through salpingo-oopherectomy, was histopathologically characterized as an immature teratoma of grade 2 and treated with 3 cycles of chemotherapy. After 3 years of completing treatment, the patient suffered from severe anemia which was investigated by capsule endoscopy that identified a bleeding source in the ileum. Imaging studies revealed an intrabdominal mass that was resected laparoscopically. The pathological assessment of the mass identified a submucosal/intramuscular teratoma with mature elements indicative of a recurrent metastasis of immature teratoma associated with post-chemotherapy retroconversion. The secondary mass was then managed with adjuvant chemotherapy.

We report a rare case of immature renal teratoma in a 5-month-old female infant. The patient presented with abdominal mass, which was found to arise from the left kidney. The preoperative diagnosis of Wilms’ tumor was based on clinical and imaging findings. The patient was managed with nephrectomy and had normal recovery. The histopathological examination of nephrectomy specimen revealed grade 2 immature teratoma.

Meconium Pseudocyst

Fetal meconium peritonitis (MP) is a rare occurrence. Neonate that survives this rare condition is likely to form a meconium pseudocyst. Hereby, we present a case of a 33-year-old pregnant woman that presented with premature rupture of membranes at 34 weeks of gestation. Antenatal ultrasonography at 33 weeks revealed abnormal dilated bowel within the viable fetus. An emergency Cesarean section was performed and a baby boy was delivered at 34 weeks. Physical examination of the baby at birth revealed a palpable central abdominal mass. Lower gastrointestinal contrast imaging revealed a non-opacified dilated proximal small bowel and opacified collapsed distal small bowels and colon. A laparotomy was carried out and revealed MP with pseudocyst formation due to a midgut volvulus. Interestingly, meconium contamination was confined due to associated atretic small bowel which occurred secondary to the volvulus.

Abstract INTRODUCTION Germ cell tumors in the central nervous system (CNS) typically arise either at suprasellar and/or pineal region, and occasionally at basal ganglia. We report a case of diagnostically challenging, recurrent germ cell tumor presented with diffuse intraaxial abnormality in and across the lower brainstem, which was diagnosed by the elevated placental alkaline phosphatase (PLAP) level in cerebrospinal fluid (CSF). CASE DESCRIPTION: A 28-year-old man had been treated by chemoradiotherapy at the previous hospital for bifocal suprasellar and pineal lesions with the provisional diagnosis of germinoma without histological confirmation. Three years later, he presented with progressive weakness of bilateral extremities for weeks. Magnetic resonance imaging showed a diffuse, bilaterally symmetric high intensity lesion on T2-weighted image with slight contrast enhancement across the ventral side of the medulla oblongata to the upper cervical spinal cord. Serum and CSF hCG, hCG-β, and AFP were all negative. Since the image findings were atypical for recurrent germ cell tumor, some kind of myelitis was initially suspected. Therefore, steroid pulse therapy was administered. However, the patient’s symptom was still gradually progressing. Then, the CSF PLAP turned out to be positive, indicating the recurrence of germinoma. Accordingly, platinum-based chemotherapy was administered, and the imaging findings, patient’s symptoms, and CSF PLAP began to improve. The patient is to be treated with radiotherapy following chemotherapy. CONCLUSION We report a rare case of CNS germ cell tumor that presented with diffuse intraaxial lesion in the lower brainstem in which examination of CSF PLAP was extremely useful.

Adhesive Intestinal Obstruction

Perineal hernia with bowel gangrene is uncommon but known complication of laparoscopic extralevator abdominoperineal excision (ELAPE). We present a rare case of closed loop small bowel obstruction with bowel gangrene secondary to an incarcerated perineal hernia that developed 7 years after an ELAPE. Intraoperatively, we found a definitive transition point due to adhesions in pelvis and a closed loop obstruction of the distal small bowel at different site with gangrenous intestine. She was managed successfully surgically with adhesiolysis and fixation of defect with biological mesh. Prevalence of perineal hernias will rise in future because of the increasing cases of ELAPE, in which no repair of pelvic floor is performed. The need of follow-up of these operations and more reporting of such cases are important in increasing awareness of these complications. Patients should be made aware of such complications and should seek urgent medical care.

Mediastinal Germ Cell Tumors

Mediastinal germ cell tumors are extragonadal germ cell tumors (EGGCTs) commonly seen in children and young adults. They are more common in men. Clinically they are classified as teratomas, seminomas, and nonseminomatous germ cell tumors. Primary mediastinal yolk sac neoplasm is an extremely rare tumor. We present here a very rare case of primary yolk sac tumor of the anterior mediastinum in a 73-year-old male. Mediastinal germ cell tumors have a worse prognosis than gonadal germ cell tumors. Chemotherapy followed by adjuvant surgery improves overall response in EGGCTs. However, comorbidities can render treatment with chemotherapy and surgery challenging in elderly patients.

Metaplastic Breast Carcinoma

Paraneoplastic syndrome affects less than 1% of cancer patients. Diagnosis of paraneoplastic syndrome with neurological presentation requires screening for an underlying malignancy, including a complete history, physical examination and imaging studies. Treatment often results in symptom stability, rather than improvement. Paraneoplastic polymyositis can precede or instantaneously occur at diagnosis or treatment of a primary tumour, while neurological symptoms can persist even following cancer treatment. We report a rare case of metaplastic breast carcinoma with an unusual presentation of paraneoplastic polymyositis.

Ovarian Mass

Struma ovarii, also known as goiter of the ovary is a rare disease.1 Considering the rarity of this tumor and constrained literature in Nepal’s context, we hereby present a case of a 46-year-old female, asymptomatic, with normal blood parameters who presented with an abdominal mass. She was suspected of malignant ovarian mass on an ultrasonogram. Intraoperative frozen section examination revealed a benign tumor suggestive of dermal tumor versus struma ovarii. Postoperatively, histopathological examination was performed to assess the percentage of thyroid tissue and a diagnosis of benign struma ovarii was made which was confirmed by thyroglobulin positivity on immunohistochemistry. No features of immature teratoma and malignancy were identified.
