Carcinosarcoma of the lung is a rare turner with an admixture of malignant epithelial(carcinomatous) and malignant mesenchymal (sarcomatous) components. Clinicopathologically, pulmonary carcinosarcoma has been divided into two types by its anatomical locations and growth nature, peripheral parenchymal and central endobronchial variants. We experienced an endobronchial carcinosarcoma that induced complete atelectasis of the right lung due to polypoid growing mass from the right upper lobe bronchus in a 67 year old male smoker. The patient underwent a successful right pneumonectomy. The tumor was composed of squamous cell carcinoma with variable sarcomatous differentiation into myogenous and undifferenciated sarcoma that demonstrated by immunohistochemical study. The patient has been doing well for the last seven months since the operation, without metastases or turner recurrence.

A 12-year-old, castrated male, mixed dog presented with a history of gradual abdominal distention for a year and anorexia recently, with abdominal radiographs showing a gastric pylorus distention. A solitary, pedunculated, heterogeneous mass arising from the mucosal layer in the pylorus with intact wall layers was identified during ultrasound and computed tomography. The gastric muscular layer was evenly thick. After surgical excision of the mass, histological examination confirmed hypertrophic pyloric gastropathy with polypoid growth and Helicobacter spp. infiltrating the gastric mucosal epithelium. This is the first reported diagnostic imaging case of hypertrophic pyloric gastropathy with Helicobacter spp. in a dog.

Enteritis cystica profunda (ECP), a rare and benign condition, is defined as the displacement of the glandular epithelium into the submucosa and more profound layers of the small intestinal wall leading to the formation of mucin-filled cystic spaces. ECP frequently occurs in the ileum or jejunum and is associated with diseases such as Crohn disease and Peutz-Jeghers syndrome. ECP also develops in the absence of known pathology. ECP in the duodenum is very rare and mostly occurs without associated conditions. In this report, we present a rare case of ECP without an associated disease, in the second portion of the duodenum distal to the ampulla of Vater and coexisting with lipoma within the polypoid lesion.

조기위암은 림프절 전이에 상관없이 위점막이나 점막하층까지 암이 국한된 것으로 정의된다. 진행성 위암에 동반된 간전이율은 $5\~12\%$이나 조기위암에 동반된 간전이는 드물다. 64세 여자 환자나 상복부 통증을 주소로 성빈센트 병원에 내원하여 시행한 위내시경 검사에서 위전정부에 폴립형 종괴가 있었으나 간전이 소견은 없었다. 수술 시 간에 단일 전이가 발견되었으며, 2군 림프절을 포함하여 원위부 아전절제술과 전이된 간이 절제술을 시행하였다. 조직검사에서 위전정부의 종괴는 선종의 일부에 선암성 변화가 있었고 이는 위점막에 국한되어 있었으며, 절제된 간은 선암의 소견을 보였다. 저자들은 조기위암에 동반된 간전이 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

Skin cancer, which often occurs as a result of skin exposure to ultraviolet light radiation, usually presents with characteristic abnormal features, such as ulcerative lesions, irregular morphology, bleeding, and excessive growth. Therefore, skin cancer rarely resembles a benign tumor on visual inspection. Nonetheless, squamous cell carcinoma and basal cell carcinoma with nodular or polypoid features can have a similar appearance to that of benign tumors, meaning that they are sometimes misdiagnosed as benign. As benign and malignant tumors have some overlapping features, clinicians sometimes use additional imaging techniques such as ultrasonography to improve the accuracy of the diagnosis because even a malignant tumor that externally resembles a benign tumor generally has internal morphological features characteristic of malignancy, such as invasion and irregular borders. However, these imaging tools also have limitations, and punch or excisional biopsy can be needed if malignancy cannot be completely ruled out. Herein, we report a case of skin malignancy initially misdiagnosed as a benign epidermal cyst based on external visual inspection and ultrasonography.

Melanoma can occur as a metastasis within subcutaneous tissue, lymph nodes, or viscera without a detectable primary tumor. Among patients with metastatic melanoma of unknown primary lesion, those with endobronchial metastasis are exceedingly rare. Herein we report a case of an endobronchial and pulmonary metastasis in a patient with melanoma originating from an unknown primary site. The patient without a previous history of melanoma presented with blood-tinged sputum. Fiberoptic bronchoscopy revealed a black polypoid tumor obstructing the posterior basal segmental bronchus of the right lower lobe. A final diagnosis of the malignant melanoma was made based on an immunohistochemical study of the bronchoscopic biopsy specimen. Skin, ophthalmic, oral, and nasal examinations failed to identify occult primary lesions. Subsequent evaluation including positron emission tomography/computed tomography scans did not uncover any abnormalities other than the metastatic pulmonary melanoma. We also describe the characteristic bronchoscopic features of melanoma.

폐실질내 과오종에 비해 기관지 내 과오종은 드문 질환으로 폐실질 내 과오종이 우연히 발견되는 것에 비해 기관지 내 과오종은 기관지 폐색에 의한 증상이 유발되어 발견되는 경우가 많다. 47세 남자가 한 달간의 기침을 주소로 내원하였다. 기관지 내시경에서 좌상엽 전구역을 페쇄하고 있는 과오종이 발견되었으며 좌상엽전구역 절제술로 제거되었다. 저자들은 좌상엽 전구역 절제술로 제거된 기관지내 과오종을 경험하여 보고하는 바이다.

Mucosal melanoma of the head and neck is a rare and usually lethal disease. Primary laryngeal malignant melanoma(LMM) are exceedingly rare tumors that morphologically are readily confused with more common types of laryngeal cancer. Treatment of choice for LMM is complete surgical excision and elective lymph node dissection is usually not recommended. The use of radiation or chemotherapy is generally thought to have no effect on local or distant disease and currently used as adjuvant therapy. The prognosis is extremely poor. We have experienced a 61 year old male patient with symptoms of foreign body and lump sense in throat. A dark pigmented polypoid mass was found on the right aryepiglottic folds with normal mobility of vocal cord. Total laryngectomy was performed under the diagnosis of malignant melanoma. Bone scan revealed multiple bony metastasis on ribs and lumbar vertebrae after 5 months of operation. There have been no evidence of recurrence at primary area. The patient died after 8 months of operation.
