Paraffinoma is a well known complication of previous paraffin injection into the subcutaneous layer that presents as various conditions including firm mass formation, edema, induration, ulceration, and skin necrosis. Paraffinoma can mimic neoplasm on physical examination and imaging studies and may complicate ultrasonographic diagnoses due to typical posterior shadowing and high echogenicity. When paraffinomas involve around the thyroid gland, the diagnosis of thyroid tumors is very difficult. We present a case of thyroid cancer, the evaluation of which was complicated by the presence of cervical paraffinoma.

The authors analyzed ultrasonographic findings of 112 cases of trophoblastic disases which were confirmed byD&E or hysterectomy at Wallace Memorial Baptist Hospital from September 1980 to December 1984. The results were asfollows; 1. Of all 112 cases, hydatidiform moles were 99 cases, invasive moles were 3 cases and choriocarcinomas were 10 cases. 2. 81 cases (72%) occurred in 3rd decades. 3. The sized of uterus was large for gestational weeksin 65 cases(56%) and smaller in 13 cases(13%). 4. The contour of uterus was globular in 59 cases(53%), diffuse in49 cases(44%) and nodular in 4 cases(3%). 5. The internal echopatterns of uterus revealed numerous small vesicular snowstorm patterns in all cases, and revealed internal degeneration in 67 cases(60%). 6. Uterine walls in 89 cases(79%) were well delineated but uterine walls in 23 cases(21%) were poor delineated. 7. Multiseptated ovarian thecalutein cysts were seen in 36 cases (32%). 8. Invasive trophoblastic disease(invasive moles 3 cases andchoriocarcinomas 10 cases) revealed similiar ultrasonographic findings with H-mole, but more irregular internalechoes and irregular echoes in uterine wall. 9. Diagnostic accuracy was diagnostic in 98 cases (88%) , nonspecificin 11 cases (10%) and error in 3 cases(2%).

PURPOSE: The perforator flaps have established their role in the reconstruction of various soft tissue defects. For the last five years, we have extensively used anterolateral thigh (ALT) flap for the reconstruction of the complex tissue defects of the hand and upper extremity and report the clinical results and our experiences with the versatile applications of this flap. MATERIALS AND METHODS: From March 2003 through May 2008, 119 free ALT perforator flaps were transferred for reconstruction of the complex tissue defects of the elbow, forearm, wrist and hand after crushing or degloving injuries as well as severe scar contractures. There were 95 females and 24 males. The mean age of the patients was 37 years and mean size of the flap was 170 cm(2). In 20 cases, the flap was vascularized by septocutaneous and in 99 cases by musculocutaneous perforators. Intra-muscular dissection length averaged 3.4 cm. The total length of pedicle averaged 8.4 cm and the average arterial diameter was 0.84 mm. End-to-end arterial anastomosis was performed in 103 cases and end-to-side in 16 cases. RESULTS: Flap survival rate was 98.3%(117/119) and there were 6 cases of partial necrosis. Donor site was closed primarily in 41 cases and skin grafts were applied in 78 cases. CONCLUSION: The reliability and versatility of ALT flap makes it one of the foremost choices for the reconstruction of complex tissue defects of the upper extremity.

PURPOSE: The cervical lymph nodes are the most common sites of locoregional recurrence in patients with papillary thyroid carcinoma (PTC). Accurate tumor localization is important for the successful removal of impalpable recurrences in the cervical lymph nodes. We evaluated the benefits of ultrasound-guided localization (UGL) performed by a single surgeon on site. METHODS: Of 53 PTC patients who underwent reoperation for impalpable nodal recurrences, 32 (group 1) were assessed only using preoperative imaging, while 21 (group 2) were additionally evaluated by on-site UGL performed by the operating surgeon. Postoperative outcomes were compared between the two groups. RESULTS: Operation times were significantly shorter (P < 0.001) and the mean size of the resected lymph nodes were smaller (P = 0.013) for group 2 patients. More lymph nodes were identified and resected in group 1 (3.56 vs. 3.19), but the rate of positive lymph nodes was significantly higher in group 2 (P < 0.001). There were no differences between the two groups in terms of resection success rate, complication rate, and postoperative hospital stay. During a mean follow-up period of 27.6 months, 52 patients (98.1%) showed no evidence of recurrence on routine ultrasound, and serum thyroglobulin concentrations remained < 1 ng/mL in 49 patients (92.5%). CONCLUSION: On-site UGL performed by the operating surgeon is useful for accurate resection of impalpable nodal recurrences in PTC patients.

PURPOSE: In this study, the authors attempted to evaluate the stage migration phenomenon according to D1 lymphadectomy and D2 lymphadectomy in the same patients. METHODS: A retrospective study was performed in 300 consecutive patients with gastric cancer who had undergone curative resection with nodal yields of D2 or more from 1994 to 1997. The lymph node status was evaluated in two different extents. Group B included patients with whole harvested regional lymph nodes (D2<) while group A include patients with perigastric lymph nodes (D1). Each group was staged by the number of involved lymph nodes according to the UICC-TNM stage (5th), and by the ratio of involved to resected lymph nodes. Stage migration and the difference of 5YSR were observed between the two groups. RESULTS: In staging by the number of involved lymph nodes, 25 cases (8.3%) of group B were staged up. According to the status by the ratio of involved lymph nodes, 14 cases (4.6%) of group B were staged up and 28 (9.3%) were staged down. CONCLUSION: In the staging of gastric cancer, adequate lymph node dissection was essential for accurate lymph node staging. In the cases of limited lymph node dissection, some extent of stage migration was considered assessing in the prognosis.

PURPOSE: Ultrasound (US) and US-guided fine needle aspiration biopsies (FNAB) are considered the modalities of choice for assessing lymph nodes suspected of containing metastases, but the sensitivity of FNAB varies and is specific to the operator. We analyzed the risk of FNAB providing false negative results of lateral neck node metastasis, and evaluated diagnostic accuracy of FNAB, in patients with papillary thyroid cancer. MATERIALS AND METHODS: FNAB was performed in 242 patients suspected of having lateral neck node metastasis on preoperative imaging. Thyroglobulin in the fine-needle aspirate washout (FNA wash-out Tg) and computed tomography enhancement (Hounsfield units) were measured. Patients with negative results on FNAB were examined by intraoperative frozen section. The false negative and true negative groups were compared. RESULTS: Of the 242 patients, 130 were confirmed as having lateral neck node metastases. In 74 patients, the metastasis was identified by FNAB. False positive results were observed in 2 patients (0.8%) and false negatives in 58 (44.6%). Risk analysis showed that patient age <45 years (p=0.006), tumor size >1 cm (p=0.008) and elevated FNA wash-out Tg (p=0.004) were significantly associated with false negative results on FNAB. The accuracy of FNAB increased significantly when combined with FNA wash-out Tg (p=0.003). CONCLUSION: To reduce the false negative rate of FNAB, patient age (<45 years), tumor size (>1 cm) and FNA wash-out Tg (>34.8 ng/mL) should be considered in preoperative planning. Accuracy may be improved by combining the results of FNAB and FNA wash-out Tg.

General anesthesia for the removal of a large mediastinal mass has been associated with life-threatening airway obstruction. We present a case of general anesthesia for a patient with superior posterior mediastinal mass and critical airway compression who was allowed to maintain spontaneous ventilation throughout general anesthesia for a thoracotomy. The patient was a 5-year-old boy complaining of productive cough and intermittent fever for 3 weeks. His chest radiograph and magnetic resonance imaging(MRI) film demonstrated a critically narrowed and deviated trachea at the level of the thoracic inlet to the proximal portion of the right bronchus. We can secure the airway by spontaneous ventilation without muscle relaxation and allowing the patient to breathe spontaneously and insertion of endotracheal tube distal to the narrowed portion of trachea.
