Histologic subtypes of invasive lobular carcinoma in correlation with tumor status and hormone receptors.

Invasive lobular carcinoma is a distinct biological entity with several histologic variants the prognostic value of which is not fully elucidated. The aim of this study was to determine the immunohistochemical expression of estrogen receptors (ER) and progedterone receptors (PR) in subtypes of lobular breast carcinoma (classic and variant types) and to correlate them with clinical and tumor parameters. Fifty lobular carcinomas, i.

Simultaneous occurrence of chronic lymphocytic and chronic myeloid leukemia.

The coexistence of chronic lymphocytic (CLL) and chronic myeloid leukemia (CML) in the same patient has only been reported occasionally. Most of these cases represent the patients who developed CLL during the course of CML. Reviewing the literature, only a few cases of simultaneous occurrence of CLL and CML were found.

Hodgkin's lymphoma variant of Richter's syndrome.

Chronic lymphocytic leukemia/small lymphocitic lymphoma (CLL/SLL) is low-grade malignant lymphoprolipheration, that has tendency to convert to a higher-grade neoplasm over time. More common is the development of a diffuse large cell lymphoma or transformation into prolymphocytic cell population. In rare cases, 0.
