Hepatopulmonary syndrome (HPS) is present in 10-32% of chronic liver disease patients, carries a poor prognosis and is treatable by liver transplantation (LT). Previous reports have shown high LT mortality in HPS and severe HPS (arterial oxygen (PaO(2)) < or =50 mmHg). We reviewed outcomes in HPS patients who received LT between 2002 and 2008 at two(More)
Iniencephaly is a rare neural tube defect characterized by extreme retroflexion of the head with the absence of neck due to spinal deformities. The important features that help us to diagnose a case of iniencephaly are occipital bone deficit leading to enlarged foramen magnum, fusion of malformed cervical and thoracic vertebrae, and upward turned face with(More)

A skin adnexal tumor located in the breast is unusual and is one of the differential diagnoses for subareolar breast nodules. With the exception of gynecomastia, other lesions of the male breast are not very common. The review of literature showed only 25(More)
We previously demonstrated that the human endometrium synthesizes and secretes a specific protein designated "Progestagen-associated Endometrial Protein" or PEP. This work was undertaken to determine luteal phase levels of PEP in serum of cycling women with histologic evidence of adequate endometrium (endometrium in phase) or inadequate endometrium(More)
Primary synovial sarcoma (SS) of kidney is very rare and difficult to diagnose. Here, we present a case of a 21-year-old female clinically diagnosed as renal cell carcinoma. Right nephrectomy specimen showed a cystic tumor in the upper pole of kidney with areas of hemorrhage and solid growth. Histologically, it showed poorly differentiated cells with(More)
Malignant oncocytoma is a rare clinical entity and is most commonly seen in the salivary glands. Its occurrence in the nasal cavity is extremely rare, and only 4 such cases have been reported in the literature. The authors report one such case in a 60-year-old woman, which presented as a slow-growing nasal mass arising from the nasal septum, with no lymph(More)
Meckel Gruber syndrome (MKS) is a lethal, autosomal, recessive, multisystemic disorder, associated with mutations affecting ciliogenesis. Since the time it was first reported; only 200 cases have been reported. From January 2004 to December 2010, we evaluated 268 fetal autopsies in our institute, in the Department of Pathology; two of these fetuses were(More)
