Diffuse coexpression of thyroid transcription factor-1 and p40 in a non-small cell carcinoma of the lung: Second case in the female population.

Some non-small cell carcinomas of the lung can express TTF1 and p40 in the same tumor cells. This event has been described in only six cases prior to this one, and only in one other female. It is an extraordinary event that appears as a new entity yet to be defined.

Is prophylactic gastrectomy indicated for healthy carriers of CDH1 gene mutations associated with hereditary diffuse gastric cancer?

Introduction: hereditary diffuse gastric cancer (HDGC) is a recently reported hereditary cancer syndrome. Patients with suspected HDGC must be under surveillance via endoscopy and multiple biopsies. As an alternative, some studies suggest prophylactic gastrectomy (PG) for disease carriers.

Liver transplantation in patients with type IIIa glycogen storage disease, cirrhosis and hepatocellular carcinoma.

Type III glycogen storage disease (GSD-III) is an autosomal recessive disorder due to the deficiency of the glycogen debrancher enzyme. 80% of the patients have hepatic and muscular involvement (IIIa), compared to 15% with only liver involvement (IIIb). As the life expectancy improves in these patients, the possible liver complications are better understood.

[The value of immunohistochemistry using SMARCA4/BRG1 in the diagnosis of small cell ovarian carcinoma hypercalcemic type. A report of two cases].

Small cell carcinoma of ovary-hypercalcemic type is an undifferentiated carcinoma. We describe two cases in women aged 32 and 29. Both presented with large masses and complete surgical extirpation was impossible.
