Large sacrococcygeal teratoma hindering vaginal delivery attempted at home.

Sacrococcygeal teratoma in fetus is rare. If it remains antenatally undiagnosed, it may cause sudden arrest of an otherwise uncomplicated vaginal delivery because of the tumor mass. This poses a challenge to obstetricians. In this era of widespread antenatal care, this type of complication is very rare; however, in such cases, if met unexpectedly, an urgent laparotomy followed by a reduction of the tumor mass might help in completion of the delayed delivery.

Guided fine needle aspiration cytology of retroperitoneal masses - Our experience.

BACKGROUND: Early pathological classification of retroperitoneal masses is important for pin-point diagnosis and timely management. AIMS: This study was done to evaluate the usefulness and drawbacks of guided fine needle aspiration cytology (FNAC) of retroperitoneal masses covering a period of two years with an intention to distinguish between neoplastic and non-neoplastic lesions and to correlate with histologic findings. MATERIALS AND METHODS: FNAC was done under radiological guidance in all cases using long needle fitted with disposable syringe. Appropriate staining was done and cytology was correlated with histology which was taken as the gold standard for comparison. RESULTS: Fifty-one patients who presented with retroperitoneal masses were studied. Forty-four lesions were malignant cytologically and 7 were inflammatory (tuberculous). According to radiological and cytologic findings, we classified our cases into four groups: renal tumors, retroperitoneal lymphadenopathy, germ cell tumors, soft tissue tumors. Except for cases of non-Hodgkin lymphoma (NHL) and metastatic lesions, we had sensitivity and specificity of 100%. In NHL the sensitivity and specificity were both 50%. In cases of metastatic adenocarcinoma, the sensitivity and specificity were 84.6% and 81.8%, respectively. CONCLUSIONS: Ignoring the pitfalls, guided FNAC is still an inexpensive and reliable method of early diagnosis of retroperitoneal lesions.

Hydatid cyst of ovary- a rare entity.

Hydatid disease is a zoonosis caused by the larval stage of Echinococcus granulosus. It is prevalent in areas where livestock is raised in association with dogs. Humans are the accidental intermediate host. Primary peritoneal echinococcosis is a rarely observed clinical condition. We report a case of peritoneal hydatid cyst diagnosed incidentally during an operation performed for suspected ovarian cyst.

Calcified pure uterine lipoma mimicking myoma.

Pure lipoma of the uterus is a rare entity and only a few cases have been reported in the literature. Clinical symptoms and signs are similar to those found in leiomyoma and create preoperative diagnostic confusion. The histogenesis is still unclear. We report the case of a 70 year-old woman with pure lipoma of the uterus with calcification.
