Nasal oral fistula revealing Langerhans´ cell histiocytosis in adult patient: case report.

Langerhans cell histiocytosis (LCH) is a rare systemic disease caused by proliferation of mature histiocytes; its association to histiocyto fibroma is rarely reported. It rarely affects adults. We report a case of systemic LCH, in an adult patient with osteolytic lesion causing a fistula between the left nasal cavity and hard palate, involving the bone, lung, lymph node and associated to multiple histiocyto fibroma.

Adenocarcinoma of intestinal type arising in mature cystic teratoma of ovary: A diagnostic dilemma.

Adenocarcinomas of intestinal type arising in mature cystic teratoma of ovary (MCT) are extremely rare and remain a diagnostic dilemma because of its similarities with MCT. Serum tumor markers CEA and SCC and also MRI may help in the preoperative diagnosis. Pathologist experience helps in intraoperative diagnosis.

Expression of topoisomerase II alpha, ki67, and p53 in primary non-muscle-invasive urothelial bladder carcinoma.

To assess the prognostic value and clinicopathological correlate of the expression of topoisomerase II alpha, ki67, and p53 in non muscle-invasive urothelial bladder carcinoma. Seventy one cases of formalin-fixed, paraffin-embedded bladder biopsy specimens diagnosed as non muscle invasive urothelial carcinoma were processed by searching our surgical pathology files from 2001-2003. The patients were followed-up for 3-77 months (median = 28).
