Authors report a case of cystic tuberculosis of left olecranon in a 44 year-old woman, which mimicked the bone tumor at initial presentation. She complained mild discomfort in the left elbow over a month. On examination there were no local redness, swelling, tenderness and deformity. There was no limitation of left elbow motion. After open curettage of the lesion, bone tuberculosis was confirmed by histological study. Postoperative triple chemotherapy of 12 months (Rifamcpicin, ethambutal, INH) could cure the disease.

An unusual case of primary leiomyosarcoma at the left lower posterior chest wall with metastasis to the right lung parenchyme is presented. The patient was a 43-year-old man who was asymptomatic but a slow growing hard mass was noted at the left lower posterior chest wall. The chest computed tomography showed a tumor at the left lower posterior chest wall with multiple metastasis to the right lung. The left lower posterior chest wall mass was examined by percutaneous needle aspiration and it was revealed as rhabdomyosarcoma histologically. En bloc resection to the left lower posterior chest wall tumor and metastasectomy to the multiple nodules in the right lung were done and pathological examination finally revealed primary leiomyosarcoma at the left lower posterior chest wall with multiple metastasis to the right lung. Chemotherapy was scheduled as adjunctive measure.

Cryptococcosis is a subacute or chronic inflammation that's caused by infection from cryptococcus neoformans in the soil or dust that's contaminated by pigeon droppings. Pulmonary cryptococcosis occurs in immunocompromised patients, and particularly in HIV positive patients, but it rarely occurs in immunocompetent individuals. It is most often detected as asymptomatic single or multiple nodules that are found by chest X-ray examination. In these situations, the diagnosis for most cases is made by the histology of the resected lesion. We report here on a case of solitary nodular pulmonary cryptococcosis that occurred in a 32 years old female patient who underwent thyroidectomy for treating her thyroid cancer.

A patient with actinomyces infection of the submandibular soft tissue was diagnosed by fine needle aspiration cytology (FNAC). A 38-year-old woman presented with a right submandibular mass which slowly grew in size over one month. Clinically and radiologically, the lesion was considered as tuberculous lymphadenitis or cellulitis. The polymerase chain reaction for tuberculosis was done by aspirated specimen but the result was negative. The smears of aspiration cytology showed characteristic colonies (sulfur granules) of actinomyces in inflammatory background. After antibiotic therapy for eight months, the patient has been well, showing no detectable mass. This patient was simply and rapidly diagnosed by FNAC and can avoid unnecessary surgical biopsy.

본 연구에는 7.0T 동물용 자기공명영상장치를 이용하여 인간의 췌장암 세포인 CFPAC-1를 이종 이식한 쥐에서 자기공명영상을 획득하여 최적화된 검사 Protocol을 정립하며, 동물 실험에서 밝혀진 종양특성과 확산강조영상과의 비교 분석을 해보고 현성확산계수 영상이 췌장암 이종이식 모형의 종양 세포 내부 구조에 관하여 어떠한 정보를 제공 할 수 있는지 알아보고자 한다. 13마리의 쥐의 26개의 종양을 전형적으로 주입 후에 2~4주 뒤에 직경이 5~10mm가 되었을 때 imaged 하였으며, pathologic specimenm을 위해 sacrificed 하였다. isofluoran gas anesthesia를 이용하여 동물 마취 하였다. 사용된 장비로는 small-animal MR images (7.0-T)를 (Bruker BioSpin GmbH, Rheinstetten, Germany)이용하여 Fast T2-weighted 와 single-shot EPI DW image를 얻었다. 종양은 H&E 염색과 CD31와 VEGF에 대한 면역조직학 염색을 하여 종양의 cellularity와 microvessel density(MVD), 종양 내 괴사 정도를 평가하였다. CFPAC-1의 현성확산계수값은 $0.7327{\pm}0.1075{\pm}10^{-3}mm2/s$이였으며, 현성확산계수는 종양내 괴사 정도와 연관성을 보였다(R = 0.7417, p = 0.0001) 이처럼 현성확산계수는 종양 내 괴사 정도 등의 현미경적구조변화를 반영하는 대리인자로 사용될 수 있음을 확인하였다.

Barrett's esophagus is precancerous lesion of esophageal adenocarcinoma, but this has been rarely reported in Korea. A 81-year-old man with esophageal adenocarcinoma was admitted to our hospital, and we performed a distal esophagectomy and end-to-end esophagogastrostomy. The microscopic examination of the resected tissue revealed the intestinal metaplasia with goblet cells around the esophageal adenocarcinoma, which indicates this was a Barrett's esophagus. We report here on this case along with a review of the relevant literature.

Brain aspergillosis has been increasing remarkably. They are known to occur commonly in immunocompromised individuals by hematogenous spread from other primary sites or by direct extension from adjacent structures to central nervous system. We report a rare case of a 29-year-old male without any known medical history, who had isolated brain lesion and the pathology from stereotactic biopsy confirmed cerebral aspergillosis.

Synchronous primary lung cancers in the same lobe are rare. Cavitating adenocarcinoma as single lung lesion is unusual. We experienced cavitating adenocarcinoma and squamous cell carcinoma in the same lobe of the lung. The patient was a 74-year-old male with chief complaints of hemoptysis. CT scan showd a central mass in right upper lobar bronchus, obstructive pneumonia, and lung abscess in the right upper lobe. Pathologically, the central mass was a 2.3$\times$1$\times$1 cm sized squamous cell carcinoma, and lung abscess was revealed as a 37272 cm sized adenocarcinoma. The patient was discharged without any specific problem after right peumonectomy.

Paraganglioma is a benign tumor arising in the paraganglion system scattered throughout the body, but its cytopathologic findings arenot well known. We experienced a case of paraganglioma of carotid body diagnosed by fine needle aspiration. The patient was a 30 year-old female who suffered from the left neck mass for 3 years. The mass was $3\times3cm$ in size without pulsation or bruit. Cytologically, the smear revealed aggregated and singly scattered tumor cells haying abundant pale cytoplasm and indistinct cell borders. Their nuclei were round to oval, but enlarged nuclei were occasionally observed. The nuclear membrane was smooth with fine clumping of chromatin. Differentiation from metastatic follicular carcinoma of the thyroid gland was difficult.
