A case of vulvar epithelioid sarcoma in 49-year old female was described. The disease originated from Bartholin's gland. The patient was treated by radical surgery and then multidrug chemotherapy and radiotherapy. In spite of intensive, multimodality treatment, the patient died after 8 months.
A case of vulvar epithelioid sarcoma (VES) in a 49-year-old female is described. The disease originated from Bartholin's gland and was originally diagnosed as vulvar squamous cell carcinoma. The patient was treated by radical vulvectomy and bilateral inguinal lymphadenectomy. Multidrug chemotherapy using doxorubicin, cyclophosphamide, vincristine, and dacarbazine was started, but had to be abandoned because of cardiac toxicity. Despite intensive treatment, the patient developed pulmonary metastatic disease and died after 8 months. The course of epithelioid sarcoma in this site seems to be more aggressive than in typical extremity locations and was consistent with other cases described in the literature.
A rare case of ectopic pregnancy in stump of uterine tube after IVF, which was done after bilateral removal of uterine tubes, caused by uterine tube pregnancies was described. Diagnostic difficulties were shown in that case.
Cytogenetic analysis of short-term tissue culture from a thecoma of the ovary demonstrated the presence of trisomies of chromosomes 12 and 4 in all analyzed cells. Our finding confirms the consistency with which trisomy 12 is observed in benign sex cord/stromal tumors and suggests that trisomy 4 may be a second event in tumorigenesis of thecoma.
Cytogenetic analysis was performed after short-term tissue culture of a thecoma of the ovary. Trisomy of chromosome 12 was revealed as the sole chromosome abnormality. This is the first report of a chromosomal aberration in thecoma of the ovary.
About 300 samples of bone tissue from femoral diaphyses and from parietal bones of calvaria were collected from human fetuses aged from 6-8 to 40-41 weeks in order to compare the kinetics of the mineralization process in endochondral and intramembranous bone formation. The crystallinity of bone mineral was evaluated by the method based on electron spin resonance (ESR) spectrometry, and mineral content was measured after ashing of the samples. Highly significant differences in the kinetics of deposition of mineral (ash content) and maturation of deposited mineral (crystallinity coefficient) were found between parietal bones and femoral diaphyses in the course of fetal development. In the early stages of development (6-8 to 10-12 weeks), the content of mineral and its crystallinity in parietal bones were significantly lower than in femoral diaphyses. In the parietal bones a gradual increase in both values was observed until they reached a plateau at the age of 30 weeks. On the other hand, in femoral diaphyses of 6-8-week-old fetuses mineral content was high and deposited mineral showed a high degree of crystallinity. Both these values did not change significantly until birth. The differences in kinetics of the mineralization process between the weight-bearing bones and bones that are not exposed to the influence of strong external forces are most probably genetically conditioned. The collected data supply embryological information and might be used in the future for evaluation of pathologic changes in skeletal development.

This is a report of a case of gynecological hemorrhage after a posterior pelvic exenteration in patients with vulvar cancer treated by temporary pelvic packing at the Department of Gynecology of the Medical University in Gdańsk. The packing was successful and the sponges were removed after 24 h. Twenty-eight days after the operation, the patient was transferred to the Department of Radiotherapy for supplementary treatment. In patients with severe intraoperative hemorrhage, intra-abdominal packing has been successful as a mode of treatment.
First-line intravenous chemotherapy (CT) following debulking surgery is associated with prolonged survival, in particular in patients who achieve a pathological complete remission (pCR) at second-look surgery but in whom a high rate of relapses still occurs. Between 1988 and 1997, 153 patients in pCR following platinum-based intravenous CT were randomized between four courses of intraperitoneal cisplatin (P) (90 mg/m2 every 3 weeks) or observation. Overall survival (OS) was the primary endpoint, while progression-free survival (PFS) was a secondary endpoint. This intent-to-treat analysis includes 16 patients who were not eligible and 17 patients who had protocol violations. The two groups were well balanced in terms of age (median = 55 years), performance status (78% P.S. O), FIGO stage (96% stage III), histology (serous in 66%), grade (2 or 3 in 80%), and residuum before intravenous CT (>1 cm in 40%). Intraperitoneal CT was delivered mainly through intraperitoneal catheters (Port-a-Cath 61% and Tenckhoff 25%). Side effects of intraperitoneal cisplatin included vomiting [> or =grade 2 (82%)], rise in serum creatinine [> or =grade 2 (14%)], abdominal pain [grade 1-2 (38%)], and neurotoxicity [grade 2-3 (15%)]. After a median follow-up of 8 years, 80 patients (52%) have progressed with no difference in the pattern of relapse between the two groups and 75 patients (49%) have died; the respective hazard ratios for PFS and OS with 95% CI are 0.89 (0.59-1.33) and 0.82 (0.52-1.29). These results are suggestive of a treatment benefit but do not support a change in clinical practice. Other randomized clinical trials of intraperitoneal CT are reviewed and briefly discussed.
We investigated the feasibility of sentinel lymph node (SN) identification using radioisotopic lymphatic mapping with technetium-99m-labeled nanocolloid and blue-dye injection in 100 patients with early cervical cancer (FIGO stage IB1 in 58, IB2 in 18, and IIA in 24) undergoing radical hysterectomy with pelvic lymphadenectomy. At least one SN was found in 84% on one side and in 66% on both sides. The sentinel detection rates according to the stages were as follows: 96.6% in IB1, 66.7% in IB2, and 62.5% in IIA with at least one SN on one side, and 86.2% in IB1, 38.9% in IB2, and 37.5% in IIA with at least one SN on both sides. Successful identification of at least one SN was less likely in patients with tumors >2 cm (54% of SN) compared with those with tumors </=2 cm (96% of SN). In 15/22 patients, the SNs were the only lymph nodes that were tumor positive. The false-negative rate for the SN procedure was 3% (3/100). In all false-negative SNs, the primary cervical tumor was above 2 cm and there was an isthmus infiltration. SN detection had 86.4% sensitivity (19/22), 100% specificity (66/66), and 95.5% negative predictive value (63/68). The sentinel node detection rate is relatively high and depends on the tumor size and FIGO stage.
Carcinoma of the Bartholin's gland is a rare lesion accounting for only 5% of all vulvar cancers. Initial diagnosis of Bartholin's gland cancer (BGC) and recurrence after primary radical surgery and adjuvant radiotherapy poses a challenge in the treatment of BGC. This case report presents a particularly aggressive course of BGC. Spontaneous rupture of the femoral artery in the postoperative period was observed. The length of the survival period from the moment of diagnosis amounted to less than 16 months. Aspects of initial diagnosis problem and treatment options in groin recurrence of vulvar carcinoma and vascular complications are discussed.
Ten women with primary ovarian carcinoma in clinical progression grade III degree according to FIGO received intraperitoneal chemotherapy. They all had surgical treatment and 9 of them received after operation intravenous cytostatics PAC or PC. Cisplatin 100-220 mg/m2 was given intraperitoneally through a Tenckhoff catheter for long-term dialysis. Before beginning of intraperitoneal chemotherapy in 6 cases the malignant lesions were under 2 cm in diameter, and in 4 cases the size of these lesions was exceeding 2 cm with far advanced disease. In patients with malignant lesions under 2 cm CR was obtained in 4 cases, SD in 1 case and PR in 1 case. In the group with malignant lesions exceeding 2 cm the results of intraperitoneal treatment were: SD in 2 cases and PD in 2 cases. Intraperitoneal chemotherapy is an effective method in ovarian carcinoma when intravenous chemotherapy is ineffective. This is another method which provides a chance of prolongation of the life of the patients.
