Two rare diagnoses during chronic lymphocytic leukaemia follow-up: Kaposi's sarcoma and Merkel cell carcinoma.

Chronic lymphocytic leukaemia often has a clinical presentation characterised by increased neoplastic lymphocytes which are mostly mature looking due to B lymphocytes. Increased secondary cancer prevalence has been detected among patients with chronic lymphocytic leukaemia diagnosis. In this report, we present three chronic lymphocytic leukaemia patients who developed secondary rare cancers during their follow-up at our clinic.

Small Cell Carcinomas of the Bladder Highly Express Somatostatin Receptor Type 2A: Impact on Prognosis and Treatment--A Multicenter Study of Urooncology Society, Turkey.

Small cell carcinoma (SmCC) is a rare and aggressive neuroendocrine carcinoma of the bladder. Neuroendocrine carcinomas expressing somatostatin receptors (SSTR) in other viscera such as lung, pancreas, and gastrointestinal system respond to therapy with somatostatin analogs. In the present study, expressions of SSTRs 1 to 5 including type 2A are investigated by immunohistochemistry (IHC) and their relationship with clinicopathologic factors was evaluated.

Synchronous endocrine tumors of small intestine: report of a case.

As with most endocrine tumors, the malignant potential depends on evidence of local or distant invasion (metastasis), so it is important to differentiate synchronous/metachronous endocrine tumors from their metastases. A 90-year-old man was operated due to tumor of the ampulla of Vater. As the surgical specimen was examined macroscopically, a second tumor focus, measuring 1 cm in diameter, was detected at the duodenum.

Secondary involvement of the breast in T-cell non-Hodgkin lymphoma, an unusual example mimicking inflammatory breast carcinoma.

Non-Hodgkin lymphoma of the breast is a rare malignancy and present with almost equal frequency either as a primary or a secondary disease. Survival is poor in most cases of secondary breast lymphoma because of their advanced stage. We report a 35-year-old woman presenting with dyspnea as well as swelling, tenderness, and ruddiness in the left breast with non-cyclic pain for several months and maculopapular skin eruption in the same breast.

A prenatally detected case of congenital hepatoblastoma.

Hepatoblastoma is a rare tumor of childhood and its incidence in the first year of life is about one in a million. Forty-two congenital hepatoblastoma cases were reported so far. Among 42 congenital hepatoblastoma patients, only seven cases have been detected in the prenatal period.

Are there any differences in the expression of hormonal receptors and proliferation markers between uterine and extrauterine leiomyomas?

The aim of this study is to determine the immunohistochemical expressions of estrogen receptor, progesterone receptor, and Ki-67 proliferation marker in 8 extrauterine leiomyomas and to compare these values with their uterine counterparts. In all, 8 patients with extrauterine leiomyomas and 20 patients with uterine leiomyomas as a control group were studied. Sections were immunohistochemically stained with estrogen receptor, progesterone receptor, and Ki-67 antibodies.

The effects of diabetes mellitus, age, and vitamin E on testicular oxidative stress.

Objective: To examine the effects of age and/or diabetes on oxidative stress and steroidogenesis, and the protective effect of vitamin E in testis tissue.

Design: Controlled experimental study.

Setting: Pamukkale University School of Medicine animal facility.
