BACKGROUND Pulmonary sclerosing hemangioma (SH) is an uncommon tumor. The aim of this study was to identify the origin of pulmonary SH and summarize its clinicopathologic features. METHODS Data of 26 cases of pulmonary SH were collected and reviewed, including their clinical symptoms, chest radiological examinations, treatments, and pathological findings. RESULTS Female patients of pulmonar...

It is the purpose of this communication to emphasize that arthralgia may be the earliest manifestation of hypertrophic pulmonary osteoarthropathy and consequently, at times, the earliest symptom of intrathoracic disease. That clubbing of the fingers is an early manifestation of hypertrophic pulmonary osteoarthropathy was suggested by Marie’ in 1890, Bamberger2 In 1891, and shortly after by Lefe...

primitive neuroectodermal tumor (pnet) is usually an aggressive, rapidly progressing and metastasizing tumor. occurrence of this type of tumor in the kidney is considered as unusual and few cases have been reported so far. we present a metastatic pnet arising probably from the kidney in a 17-year-old female patient with local invasion and metastasis to the stomach. pnet should be considered as ...

intraocular metastatic tumors have been increasingly reported in the recent past. unlike choroidal metastasis, metastasis to retina is very rare and so far has been reported in very few case reports only. case presentation : a 56 year-old male who presented with a history of adenocarcinoma of the cecum and underwent lap colectomy for the primary cecal tumor, received adjuvant chemotherapy for a...

pulmonary arteriovenous malformations are rare clinical entities thai are associated with right to left shunts, and are often clinically presented by the triad of dyspnea, cyanosis, and digital clubbing. currently, transcatheter embolization of fistula is gaining increasing popularity as the superior therapeutic option. in certain situations, however, surgery is preferred. two cases of direct p...

Low-grade endometrial stromal sarcoma (ESS) is an uncommon gynecologic malignancy of mesodermal origin. Pulmonary metastasis of low-grade ESS can occur years and decades after the treatment of the primary disease. Low-grade ESS is frequently mistaken as benign uterine neoplasm like uterine leiomyoma, which can potentially lead to a misdiagnosis. We present a case of a 42-year-old woman with low...

Cystic fibrohistiocytic tumor of the lung is a rare neoplasm. In many cases it represents a metastasis from a benign or low-grade fibrohistiocytic tumor of the skin, but occasionally it may be primary. Radiologically it usually occurs as a cystic change of multiple pulmonary nodules, and pneumothorax is the most frequent presenting symptom. We present here a 16-year-old man with recurrent right...

Development of distant metastases from renal cell carcinoma (RCC) is a frequent occurrence and, in nearly 95% of the cases, secondary lesions present within 5 years following nephrectomy. We performed a left pneumonectomy for a peri-hilar lung mass in an 81-year-old man with history of kidney cancer, resected 37 years earlier. Histopathological examination revealed a solitary lung metastasis fr...

Only a few years ago bronchial adenoma was considered a rare tumor. Recently, however, an increasing number of reports have been published of this neoplasm. On the basis of their experience Lindskog and Liebow3 hold that bronchial adenomata comprise 4 to 5 per cent of all pulmonary neoplasms. An adenoma originating in the bronchial wall gives rise to symptoms of obstruction, infection and haemo...
