RESUMEN
Granular cell tumor is characterized by large eosinophilic cells with granular appearances. These are mostly benign. Approximately 1~2% are malignant, and establishment of reliable criteria for diagnosing malignant granular cell tumor has been difficult to establish because of the rarity. Reports on the cytologic features of this neoplasm are hardly found in Korea. We report a case of rarely-occurring granular cell tumor in the lower leg of a 40-year-old male, diagnosed on fine needle aspiration cytology, together with a review of the literature regarding significant adverse histology and prognostic factors. The aspirates revealed cellular smears of isolated cells, syncytial clusters, and occasionally stripped nuclei in a fine, bluish-purple, granular background. Tumor cells were polygonal, rounded, or slightly spindled, and showed ill-defined granular cytoplasm. Nuclei were small and round or oval, with inconspicuous or small, prominent nucleoli. The nuclei showed rare intranuclear cytoplasmic invagination. Occasionally, there were mild to moderate nuclear pleomorphisms with vesicular nuclei, with large, prominent nucleoi, but no mitosis. The immunocytochemical stain for S-100 was strongly positive in the cytoplasm of tumor cells with occasional nuclei.

Abdominal pregnancy is a rare form of extrauterine pregnancy which is account for 1.4% of all ectopic pregnancy cases. Among these omental pregnancy is extremely rare and may cause life-threatening massive hemorrhage as a complication. But the diagnosis of early abdominal pregnancy is difficult because of non specific findings about clinical history, physical examination and ultrasonography. Risk factors related to ectopic pregnancy include inflammation, infection and surgery, but endometriosis is an uncommon factor. We present a case of the ruptured primary omental pregnancy associated with endometriosis with a review of the literature.

Parovarian cysts constitute 10% of adnexal masses. They were found in broad ligament and mostly arise from mesothelium and less commonly from paramesonephric element and rarely from mesonephric element. In most cases parovarian cysts were asymptomatic. So, they were found incidentally at surgery for other conditions. Torsion is infrequent and it is difficult to distinguish it from torsion of other adnexal masses, appendicitis, etc. Recently, we experienced a voluminous parovarian cyst undergoing torsion, 25 cm in diameter. The case is presented with a review of literature.

Condyloma acuminatum is a manifestation of human papillomavirus (HPV) infection. The genital warts tend to occur in areas most directly affected by coitus, namely external genitalia, perineum and perianal areas. The warts are highly contagious; more than 75% of sexual partners develop when exposed. The warts frequently increase in number and size during pregnancy, sometimes filling the vagina or covering the perineum, making it difficult to perform vaginal delivery or episiotomy. Probably small number of infants and children born of women with genital warts will become infected and develop laryngeal papillomatosis. We have experienced one case of huge condyloma acuminatum during pregnancy and presented with a brief review of literature.

Blue nevus of the uterine cervix is a rare benign pigmented lesion consisting of dermal melanocytes in the stroma. It is similar to those of common blue nevus of the skin. Most of these are clinically or colposcopically unsuspected and an incidental finding often found in hysterectomy specimens. The case here was incidentally found in surgical pieces after hysterectomy in 43-year-old women performed for leiomyoma. We report a case of blue nevus of the uterine cervix with a review of the literature.

Schizencephaly is an unusual condition rarely detected antenatally. It is a neuronal migrational disorder consisting of clefts in the brain that communicate with the lateral ventricles. The etiology and the pathogenesis is not clearly estabilished. While some authors advocate a vascular insult with a secondary effect on brain development, others suggest a primary cerebral dysgenesis by genetic or acquired factors. The importance of making an accurate antenatal diagnosis is that the outcome for schizencephaly in considerably poor than for other causes of ventriculomegaly. Typical symtoms include seizures, mental retardation, spastic tetraplagia and blindness. We report a case of typeIIschizencephaly that was diagnosed antenatally in the third trimester with a brief reiew of literatures.

Cervical pregnancy is a rarely life-threatening form of ectopic pregnancy in which the implantation of the developing conceptus in the cervical canal. The cervix is composed predominantly of the fibrous tissue. Therefore cervical pregnancy can be massive hemorrhagic occurrence from the eroded blood vessels within the cervical tissue. In the past, as a result of life-threatening hemorrhage, the diagnosis of a cervical ectopic pregnancy frequently led to hysterectomy. Currently, several conservative treatments are possible with the hope of preserving future reproductive potential, including preoperative uterine artery embolization before dilatation and evacuation. We report a case of cervical pregnancy which was treated sucessfully with preoperative selective uterine artery embolization before dilatation and currettage.

Primary ovarian pregnancy is a rare form of ectopic pregnancy, and the prevalence rate is reported to be between 1/7,000 and 1/40,000 pregnancies. Ovarian pegnancy occurs within the ovary and on the corpus luteum, usually with rupture and massive bleeding. It is frequently misdiagnosed as a ruptured corpus luteum and the differentiation may be made only by micoroscopic examination of a tissue specimen. We have experienced four cases of ovarian pegnancy, which are presented with a brief review in the literature.

Mature cystic teratoma of the ovary is the most common ovarian germ cell neoplasm comprising (10-20%) of all ovarian tumors and almost always benign, but it can be developed into malignancy rarely. We have recently experienced one case of squamous cell carcinoma arising in mature cystic teratoma of the right ovary in 67-year-old postmenopausal woman. The ovarian tumor was measured 17x12.5x8 cm in size and had not intact capsule, and the peritoneal washing cytology was positive. The survival rate with cancerous dermoid is very poor. Neither of two forms of postoperative treatment (radiotherapy and chemotherapy) has any significant influence on survival. We report above case with a brief review of literature.

Adenoid basal carcinoma of the cervix is very rare tumor. It is slow-growing and locally invasive tumor amenable to simply hystrectomy. It is common to be associated with severe dysplasia and carcinoma in situ(CIS) of cervix Occasionally, concommitant microinvasive squamous cell carcinoma or adenocarcinoma may also be seen. Differential diagnosis includes adenoid cystic carcinoma, which is more aggressive tumor associated with regional lymph node involvement and late pulmonary metastasis. We have recently experienced a case of adenoid basal carcinoma of the cervix in 61 years-old woman, which is presented with a brief review of the literature.
