Florid pseudoepitheliomatous hyperplasia related to tattoo: a case report.
Pseudoepitheliomatous hyperplasia is a benign condition defined by an exuberant proliferation of the epithelium with downward progression into the dermis. It may occur in reaction to several conditions including chronic cutaneous wound. We describe an unusual case of a florid pseudoepitheliomatous hyperplasia mimicking a well-differentiated squamous cell carcinoma, restricted to the red part of...
متن کاملAre AgNORs useful in distinguishing follicular hyperplasia from follicular lymphoma?
Argyrophilic nucleolar organiser regions (AgNORs) in 28 follicular lymphomas and 30 lymph nodes showing reactive follicular hyperplasia were studied to see if they were helpful in distinguishing follicular lymphoma from follicular hyperplasia in paraffin wax tissue sections. Mean nuclear counts were greater in follicular hyperplasia (3.71 v 3.11). This difference was significant but counts over...
متن کاملThymoma and Synchronous Primary Mediastinal Seminomas with Florid Follicular Lymphoid Hyperplasia in the Anterior Mediastinum: A Case Report and Review of the Literature
Thymoma is the most common neoplasm of the anterior mediastinum and has malignant potential. Germ cell tumors (GCTs) found in the anterior mediastinum are usually benign, and malignant GCTs, such as seminomas, are rare. Histologically, mediastinal seminoma is indistinguishable from testicular seminoma except for site-associated morphological features such as lymphoid follicular hyperplasia. The...
متن کاملMesonephric Adenocarcinoma of the Uterine Cervix Associated with Florid Mesonephric Hyperplasia: A Case Report
Hyperplasia and neoplasia of mesonephric remnants in the uterine cervix are uncommon conditions that are often mis-diagnosed as usual forms of cervical adenocarcinoma. Here, we report a case of mesonephric adenocarcinoma with florid mesonephric hyperplasia of the uterine cervix in a 48-year-old female patient. The cervix was slightly enlarged eccentrically, without a definite mass-like lesion. ...
متن کاملIgM expression in paraffin sections distinguishes follicular lymphoma from reactive follicular hyperplasia.
The trapping of IgM-containing immune complexes (ICs) by follicular dendritic cells (FDCs) serves as an important step in promoting germinal center (GC) formation. Thus, the deposition of IgM-containing ICs on FDCs can be detected by antibodies recognizing IgM. The present investigation provides the first comprehensive report on the IgM staining pattern in follicular lymphoma (FL, n = 60), with...
