포충증은 주로 유구낭충에 감염된 환자에 larval cysticercoid stage때 soft tissue에 전이되어 이 cysticercus가 죽음으로써 변성되고 석회화를 일으켜 국소적 소견으로는 nontender mass, 그리고 X-ray 상 typical calcification을 일으키며 조직학적 소견으로는 fibrotic cyst속에 scolex의 hooks와 sucker를 볼 수 있다. 만약 cysticercosis가 두뇌속으로 전이된다면 두뇌의 침범된 부위의 국소증상이 나타날 수 있으며 예후는 매우 나쁘다. 조직학적 소견상 포충증으로 확진되면 환자를 입원시켜 전신을 검사하여 nontender mass가 만져지면 적출하여 주어야 한다. 저자들은 우측 안면부에 nontender mass를 주소로 하여 내원한 24세 남자에서 우측 안면부에 전이된 유구낭충증 1 례를 경험하였기에 문헌적 고찰과 함께 보고하는 바이다.

Ancient (degenerated) schwannomas are benign tumors that display pronounced degenerative changes including cyst formation, calcification, hemorrhage, and hyalinization. The tumors are usually infiltrated by large numbers of inflammatory cells such as neutrophils, lymphocytes, siderophages, and histiocytes. They are located in deep locations such as the retroperitoneum and must be differentiated from malignant soft tissue tumors because spindle cells with nuclear atypia may be present. In the fine needle aspiration biopsy. The cytologic findings of two cases of ancient schwannoma occurring in posterior mediastinum and retroperitoneum, respectively, are described. Computerized tomographic findings of both cases showed changes of cystic degeneration or necrosis. A case occurred in retroperitoneum revealed features of destruction of vertebral body to suggest a malignant soft tussue tumor radiologically. The cytologic findings of aspiration biopsy of both tumors revealed that the tumor cells were spindle in shape with elongated nuclei. Some of tumor cells were arranged in a palisading fashion. Cell structures that resemble the Verocay bodies were observed. Some of the tumor cells showed pleomorphic bizarre nuclei, but no mitotic activity or chromatin clumping was seen. Inflammatory cells, siderophages and histiocytes were scattered in fibrillar material. These cytologic findings are important in the diagnosis of ancient schwannoma and in the differentiation of this tumor from the malignant spindle cell tumor.

Human cysticercosis is an infestation with C. cellulosae, the larval stage of the tapeworm T. solium. It prevails in regions of poverty and where personal hygiene is poor. They can lodge in almost any tissue, but cysticerci are most frequently found in brain, skeletal muscle, subcutaneous tissues. We experienced a 41-year old male with $5{\times}12cm$ sized movable non tender brownish hard mass at lateral abdominal wall. The laboratory study didn't show any specific symptoms except peripheral blood eosinophilia and positive parasite ELISA screen for cysticercosis. The ultrasonogram revealed multiple ill-defined mixed echoic inflamatory lesion. Excisied cyst showed multiple severe foul-odor gelatinous subcutaneous mass. Microscopic examination disclosed necrotic body with foreign body reaction, massive eosinophilia and dead parasitic organism, compatible with cysticercosis. There was no evidence of recurrence during 12 months follow-up.

Primary intraosseous carcinoma (PIOC) is a rare odontogenic carcinoma defined as a squamous cell carcinoma arising within a jaw having no initial connection with the oral mucosa, and probably developing from residues of the odontogenic epithelium. PIOC appears more common in male than female, especially at posterior portion of the mandible. Radiographic features of PIOC show irregular patterns of bone destruction with ill defined margins. It could be sometimes misdiagnosed as the cyst or benign tumor because it shows well defined margins. If it couldn't be done appropriate treatment initially, PIOC shows extremely aggressive involvement, extensive local destruction and spreads to the overlying soft tissue. Therefore accurate diagnosis in early state is necessary. The diagnosis criteria proposed for PIOC are : (1) absence of ulcer formation, except when caused by other factors, (2) histologic evidence of squamous cell carcinoma without a cystic component or other odontogenic tumor cell, and (3) absence of another primary tumor on chest radiograph obtained at the time of diagnosis and during a follow-up period of more than 6 month(Suei et al., 1994).

Objective : To retrospectively analyze the clinical characteristics and surgical experience of 10 adults with spinal extradural meningeal cysts (SEMCs) in the thoracolumbar spine which may further provide evidence for surgical decision-making. Methods : Ten adults with SEMCs in the thoracolumbar spine were surgically treated and enrolled in this study. Clinical manifestations, imaging data, intraoperative findings and postoperative outcome were recorded. Results : Clinical manifestations of SEMCs included motor and sensory dysfunction of the lower limbs and urination and defecation disturbance. The cysts presented as intraspinal occupying lesions dorsal to the spine, ranging from the T8 to L3 level. Defects of eight cases were found on preoperative magnetic resonance imaging (MRI). Selective hemilaminectomy or laminectomy were used to reveal the defect within the cyst, which was further sutured with microscopic technique. The final outcome was excellent or good in seven cases and fair in three cases. No recurrence was observed during follow-up. Conclusion : SEMCs are rare intraspinal cystic lesions. Radiography and MRI are clinically practical methods to assess defects within SEMCs. Selective hemilaminectomy or laminectomy may reduce surgical trauma. Detection and microscopic suturing of the defects are the key steps to adequately decompress the nervous tissue and prevent postoperative recurrence.

The present study was aimed to compare the resorption rate and the histological change of the autogenous dermis and the artificial dermis (Terudermis$^{(R)}$) after the transplantation, and to report the clinical results of the use of Terudermis$^{(R)}$ in order to restore the soft tissue defect. Twenty mature rabbits, weighing about 2 kg, were used for the experimental study. The autogenous dermis and the Terudermis$^{(R)}$ size 1${\times}$1 cm were transplanted to the space between the external abdominal oblique muscle and the external abdominal oblique fascia of the each rabbits. They were divided into 4 groups (n=5 each) and gathered at 1, 2, 4, and 8 weeks after the transplantation. The resorption rate was calculated, and H-E stain was preformed to observe the histological changes. The chart review of the 17 patients who received Terudermis$^{(R)}$ graft to the facial soft tissue defects was conducted for the clinical study. The resorption rate at 8 weeks after the transplantation was 21.5% for the autogenous dermis, and 36.4% Terudermis$^{(R)}$. In microscopic examinations, the infiltration of the inflammatory cells and the epidermal inclusion cyst were observed in the autogenous dermis graft. The neovascularization and the progressive growth of the new fibroblast were shown in the Terudermis$^{(R)}$ graft. In clinical data of 17 patients, the size of the grafted Terudermis$^{(R)}$ was from 1.5$cm^2$ to 7.5$cm^2$ (average 3.5$cm^2$). Follow-up ranged from 5 to 25 months. Fourteen patients with cleft palate demonstrated stability of the graft and unremarkable complications. But unstability of the graft and the partial relapse were observed in three patients received the vestibuloplasty. These results indicate that Terudermis$^{(R)}$ can be available substitute of autogenous dermis because of the stability about resorption, the histocompatibility, and the unremarkable clinical complications.

콩시스트선충 Race 3에 이병성인 대두품종 Lee와 저항성인 대두품종 Lee와 저항성인 Pickett을 공시, 3가지 다른 접종수준(식물개체당 1,760, 440, 110마리의 2기 유충)에 따른 선충의 침입과 시스트 형성을 조사하였고, 이병 뿌리조직의 형태적 변화를 관찰하였다. 선충의 침입율은 이병성 대두에서 접종수준간에 차이가 없었으나, 저항성, 품종에서는 접종수준이 높아짐에 따라 감소하였다. 그러나, 접종수준에 다른 침입율 차이의 정도는 시스트 형성, 즉 저항성과 직접적으로는 관련이 없는 것으로 나타났다. 이병성 대두품종에서 시스트 형성율은 최고접종수준에서 다소 감소하였고, 저항성 품종에서는 이병성 품종과 비교할 때 시스트 형성율이 현저히 낮아, 대두품종에서의 선충의 밀도변화는 선충의 침입보다는 선충의 생장에 관계가 있는 것으로 나타났다. 이병조직의 형태적 특징은 대두품종간에 그리고 감염정도에 따라 차이가 있었다. 이병성 품종의 뿌리조직에서는 syncytium이 형성되었으나, 여러마리 선충에 의해 감염된 부위에서는 syncytium이 접종 5일후에 퇴화하였다. 저항성 대두에서도 선충의 감염정도에 따라 이병조직의 형태변화가 다르게 나타났다. 이러한 조직병리학적인 차이는 이병성 및 저항성 대두에서의 콩시스트선충의 밀도변화에 영향을 주는 요인으로 사료된다.

Purpose: Congenital dermoid cysts develop during the fusion of the embryo when the ectodermal tissue gets trapped in the line of fusion. Dermoid cysts of the head are rare lesions comprised of epidermal and mesodermal elements. Furthermore, dermoid cysts in the occipital area are extremely rare. Only a few cases of dermoid cysts in the posterior scalp have been reported. Especially, A bilateral, synchronous presentation in this location has not been reported previously in the literature. Methods: All 5 cases had a gradually enlarging mass of the posterior aspect of the scalp. The cysts were mobile, noncompressible, and non-tender, without evidence of an associated sinus tract, skin dimpling, discoloration, or communication with adjacent structures. The CT scan displayed a hypodense cystic lesions about -87 to +24 HU (Housefield units, average +3.2 HU) with hypodense capsule and no postcontrast enhancement. All tumors were found just under the skin, and were well encapsulated, so they were completely removed the mass with adjacent periosteum. Results: On gross findings, all tumors were oval-or round-shaped, and when the cystic tumor was cut open it presented a greasy and caseous substance. Histologically, all specimens contain desquamated squamous epithelium and keratin in the lumen and are encapsulated and lined by keratinized stratified squamous epithelium. And, all cases of posterior mass are the presence of adnexal structures. Conclusion: Appropriate diagnosis requires not only an index of suspicion for this rare tumor a very careful history and search for skin changes. Especially, CT can reveal the exact location of the cyst, its relationship with the adjacent structures. We think that occipital dermoids divide into superficial and deep type. In our cases, because they did not have intra-cranial involvement or fistula formation, they are superficial type. This report describes the clinical and operative aspects of the superficial dermoid cysts and provides a review of the literatures.
