RESUMO

Ocular surface squamous neoplasia represents neoplastic epithelial abnormalities of conjunctiva and cornea, ranging from squamous dysplasia to invasive squamous cell carcinoma and is both sight- and life-threatening. Squamous spindle cell carcinoma (SSCC) of conjunctiva is a rare variant with distinct behavior which is thought to be more locally aggressive. We describe an 83-year-old woman with a progressively enlarging huge SSCC in her right eye over the past 2 years. The tumor bulged out with local invasion into intraocular and orbital cavities. Wide excision of the tumor with frozen section control was performed. After surgery, topical 0.03% mitomycin C was given as adjuvant therapy. At 40-month follow-up, the lesion site showed no evidence of local recurrence. This case provides a valuable and complete experience of the clinical presentation for the progression and treatment of this rare disease.

RESUMO

We report the findings of a Meckel scan in a 19-year-old patient treated for retroperitoneal teratoma with intermittent tarry stool for 1 month. Two focal stases of radioactivity in the right upper quadrant of the abdomen were noted. SPECT/CT for localization revealed that these 2 foci were within the displaced right kidney along with an adjacent bulky retroperitoneal mass. The patient subsequently underwent surgery, and histopathological studies confirmed recurrent teratoma. Two foci of increased radioactivity instead of 1 may have provided hints for the physiological characteristics of such lesions.

RESUMO

Typhoon Morakot pounded Taiwan in 2009 with record-breaking rainfall, washing an unprecedented amount of driftwood into the sea that was partially deposited at the coastal areas. According to the satellite imagery analysis, more than three million trees fell and were washed away to occupy 83.2% of the Taiwanese coastline, including 52 fishing harbors. The amount cleaned-up was only 1/7 of the total coastal driftwood. It was found that the amount of coastal driftwood is not only related to the amount of precipitation but is also related to the distance from the location of the landslide to the river mouth and to the landslide area. The amount of accumulated coastal driftwood demonstrated log-profile declines with increasing distance to the river mouth. Nearshore current and wave motion are the critical factors for driftwood deposition. Much of the driftwood washed into the sea harmed the tourism and fishing industries, endangered navigation and oceanic activities, and impacted the marine environment and ecosystem.
