폐에 발생한 암육종의 세침흡인 세포학적소견 -1 증례보고-
장태정,이광길,홍순원,Jang, Tae-Jung,Lee, Kwang-Gil,Hong, Soon-Won 대한세포병리학회 1990 대한세포병리학회지 Vol.1 No.2
Carcinsarcoma is an uncommon pulmonary malignancy characterized by carcinmatous parenchyma and sarcomatous stroma. The cytologic, immunohistochemical and ultrastructural features of a case of pulmonary carcinosarcoma suspected by fine needle aspiration cytology is presented. Only bizarre spindle cells arranged in loose groups, in microtissue fragments and in a dissociate fashion were present on the aspiration smears. They were markedly positive for vimentin. The epithelial component was not found, which was probably due to marked paucity of carcinomatous component that was proved by histologic examination of the resected tumor. The diagnosis of pulmonary carcinosarcoma should be conidered whenever poorly differentiated epithelial ceil groups with a malignant mesenchymal component set in a myxoid background are seen in a pulmonary cytology specimen.

암조직에 대한 면역반응은 종양의 성장을 억제하거나 유도한다. Foxp3 양성 T 림프구는 종양에 대한 면역억제 반응을 유도하여 종양의 성장을 유도하는 반면 CD8 양성 T 림프구는 종양의 성장을 억제한다. 본 연구에서는 피부에서 발생한 편평세포암종, 편평세포 암종의 전암병변인 광선각화증과 보웬병 그리고 기저세포암종 조직에 면역조직화학염색을 시행하여 CD8 양성 T 림프구 및 Foxp3 양성 T 림프구의 분포 그리고 두 종류의 림프구의 비(CD8/Foxp3)를 조사하여 다음과 같은 결과를 얻었다. CD8 양성 T 림프구와 Foxp3 양성 T 림프구는 보웬병과 평평세포암종의 침습부위에서 광선각화증과 기저세포암종의 침습부위에 비하여 더 많이 침윤하였으며 CD8/Foxp3는 보웬병에서 광선각화증과 기저세포암종의 침습부위에 비하여 낮았다. CD8 양성 T 림프구와 Foxp3 양성 T 림프구의 침윤 정도 및 CD8/Foxp3는 보웬병과 편평세포암종의 침습부위에서 유의한 차이가 없었다. 기저세포암종과 편평세포암종에서 CD8 양성 T 림프구와 Foxp3 양성 T 림프구는 침습부위에서 종양의 중심부위에 비하여 더 많이 침윤하였다. 이러한 결과로 보아 편평세포종양과 기저세포암종은 서로 다른 면역반응을 보이며 종양내에서도 부위에 따라 상이한 면역반응을 보인다고 생각된다. Cancer is subject to dynamic interactions between contrary immune reactions that drive both tumor growth and suppression. Forkhead box p3 positive T cells (Foxp3 positive T cells) might support tumor promotion, while CD8 positive T cells might protect the host. The present study examined the distributions of CD8- and Foxp3-positive T cells and CD8 positive T cells/ Foxp3 positive T cells ratio in skin squamous cell carcinoma (SCC) and its precancerous lesions; it also compared this with data for basal cell carcinoma (BCC). Iimmunohistochemical staining for CD8 and Foxp3 was conducted in 20 cases of SCC, Bowen’s disease (BD), actinic keratosis (AK) and BCC. The BD and SCC cases exhibited significantly increased numbers of both CD8- and Foxp3-positive T cells in their advancing regions compared with the AK and BCC cases, and the BD cases exhibited significantly lower CD8 positive T cells / Foxp3 positive T cells ratio in these regions than did the AK and BCC cases. There was no significant difference in both T cells and the ratio between BD and SCC. The degree of both T cells infiltration differed between the advancing and central areas in SCC and BCC. Immune microenvironments differ between cutaneous squamous cell tumors and BCC and differ as well among tumor compartments.

면역물질인 IgY가 함유된 다기능성 계란 섭취로 인체에서 H. pylori 제균 치료에 어떠한 효과를 나타내는지 알아보고자 H. pylori 양성인 위염 환자 63명을 대상으로 임의로 IgY 함유 계란 투여군(17명), 항생제 투여군(17명) 및 항생제와 IgY 함유 계란 병합투여군(16명)으로 나누고 2주간 치료하였고 IgY 정제투여군(13명)은 1개월간 치료하였다. 치료후 H. pylori 박멸률, ¹³CO₂ 변화율(Δ¹³CO₂) 및 updated sydney system에 따른 H. pylori 균체 밀도, 급만성 염증 활성도, 장상피화생을 비롯한 위축도 등의 조직학적 변화에 대한 시험결과는 다음과 같다. IgY 함유 계란 투여군, 항생제 투여군, 항생제와 IgY 함유 계란 병합투여군 및 IgY 정제 투여군에서 H. pylori 박멸률은 각각 0%, 88%, 94% 및 0%로 IgY 함유 계란을 항생제와 병합투여했을 때 항생제만 투여할 때보다 H. pylori 박멸률이 높게 나타났지만 유의성은 없었다. IgY 함유 계란 투여군 17명중 1명이 Δ¹³CO₂이 감소하는 경향을 보였지만 나머지는 변함이 없었다. 항생제와 IgY 함유계란 병합투여군 16명중 15명에서 치료 1주째 Δ¹³CO₂이 모두 4이하로 치료전보다 유의하게 감소하였으며(p<0.05), 나머지 1명도 치료 1주와 2주째 Δ¹³CO₂이 치료전에 비해 감소하는 경향을 보였다. IgY 함유 계란 투여군과 IgY 정제 투여군에서 위전정부의 급성 염증 활성도가 유의하게 감소하였다 (p<0.01). IgY 함유 계란 투여군과 IgY 정제 투여군에서 위전정부의 H. pylori 균체 밀도가 유의하게 감소하였다 (p<0.05). IgY 정제 투여군에서 위체부의 만성 염증 활성도가 감소하는 경향을 보였다. IgY 함유 계란 투여군에서 위전정부 및 위체부의 장상피화생과 위축도는 치료전후 변화가 없었다. IgY 정제 투여군의 1예에서만 치료전 위전정부에 경도의 장상피화생이 관찰되었으며 치료후 정상으로 호전되었다. 위점막 위축은 대상환자 모두에서 치료전후 변화가 없었다. This study was conducted to investigate the effect of chiken egg containing IgY againt H. pylori in patients with gastritis. Sixty three H. pylori-infected volunteers (20~43 year, Male : Female=49 : 14) were randomized into four groups which were treated with one chiken egg containing IgY b.i.d. (IgY group; n=17) or omeprazole 20 mg b.i.d., amoxicillin 1.0 g b.i.d. and clarithromycin 500 mg b.i.d. (OAC group; n=17) or omeprazole 20 mg b.i.d., amoxicillin 1.0 g b.i.d., clarithromycin 500 mg b.i.d. and one chicken egg containing IgY b.i.d. (OAC with IgY group; n=16) for 2 weeks or lyophilized IgY 1 g b.i.d (lyophilized IgY group) for 1 month. Δ¹³CO₂ before and after treatment, the eradication rate of H. pylori and histologic change including H. pylori density, acute and chronic inflammation activity, intestinal metaplasia and glandular atrophy by updated sydney system were evaluated. Eradication rate of OAC with IgY group (94%) was higher than IgY group (0%), lyophilized IgY group (0%) and OAC group (88%). Δ¹³CO₂ at 2 weeks after treatment in one patient of IgY group was decreased. But that was not changed in the other patients. Δ¹³CO₂ at 1 week after treatment in 15 patients of OAC with IgY group was significantly lower than pretreatment level (p<0.05), and Δ13CO2 at 1 week and 2 week after treatment was decreased in the other patient. Acute inflammation activity at antrum was significantly decreased after treatment in IgY and lyophilized IgY group (p<0.01). H. pylori density at antrum was significantly decreased after treatment in IgY and lyophilized IgY group (p<0.05). Chronic inflammation activity at body was decreased after treatment in lyophilized IgY group. Intestinal metaplasia and grandular atrophy at antrum and body were not changed after treatment in IgY group. Mild intestinal metaplasia in one patient of lyophilized IgY group changed to normal after 1 month treatment. Gandular atrophy at antrum and body were not changed after treatment in lyophilized IgY group.

Spontaneous infarction of fibroadenoma of the breast is very uncommon and may lead to difficulties in clinical and pathological diagnosis. Most reported cases occured in young women during pregnancy or lactation. This report describes imprint cytologic features of an infarcted fibroadenoma in a 19-year-old young woman without evidence of pregnancy. The smears revealed many individually scattered degenerated or necrotic epithelial or spindle stromai cells and naked nuclei on dirty necrotic background. A few sheets of cohesive uniform epithelial cells and a few fragments of stromal cells were also present. Most of the epithelial cells had pyknotic and hyperchromatic nuclei, however, cellular atypism such as pleomorphism, prominent nucleoli or mitosis were not present. Though the necrotic ductular and glandular outline of this case may bear a superficial resemblance to adenocarcinoma, obvious cytologic atypia or mitosis, even in the necrotic areas were not present.
A Case of Direct Invasion of the Parotid Gland by Cutaneous Squamous Cell Carcinoma
이준호,신혜경,최진수,장태정,Lee, Joon Ho,Shin, Heakyeong,Choi, Jinsu,Jang, Tae Jung Korean Cleft Palate-Craniofacial Association 2013 Archives of Craniofacial Surgery Vol.14 No.2
Cutaneous squamous cell carcinoma is the second-most common skin cancer and represents 20% of all skin cancers. Cutaneous squamous cell carcinoma often spreads to the parotid gland through lymph nodes, but, direct invasion of an adjacent organ may also occur. We present the case of 78-year-old man with ulcerated mass on the right infra-auricular area. The histopathologic finding was squamous cell carcinoma. There was no evidence of distant metastasis, but the mass was found to invade the superficial lobe of the right parotid gland. The mass was widely excised and superficial parotidectomy was performed while preserving the facial nerve. The defect was covered by primary closure. Postoperative radiotherapy was performed. At 20 months after surgery, our patient had no facial palsy, local recurrence, or metastasis. Cutaneous squamous cell carcinoma involving the parotid gland is an aggressive, rapidly advancing lesion, which if not recognized and treated early will result in high morbidity and mortality. Squamous cell carcinoma of the parotid gland has shown that patients who receive adjuvant radiotherapy have a lower recurrence rate and a higher survival rate than patients treated with surgery alone. The role of elective neck dissection remains controversial.
