Mixed Epithelial and Stromal Tumor Family of Kidney (Adult Cystic Nephroma, Mixed Epithelial and Stromal Tumor): Retrospective Clinicopathological Evaluation.

Objective: Tumors belonging to the mixed epithelial stromal tumor family (MESTF) are rare; thus clinicopathological experience about them are limited. Each epithelial and stromal component shows different patterns in these tumors.

Material And Method: Clinicopathological features of 11 MESTF cases that were diagnosed between 2000 and 2021 at a single center were evaluated.

A Case of Primary Undifferentiated Pleomorphic Sarcoma of the Lung.

Null.

Villous Adenoma Arising in the Urethra of a Female with Bladder Augmentation History: A Case Report and Review of the Literature.

Villous adenomas (VAs) in the female urethra are rare with only seven cases in the English literature to our knowledge. In patients with bladder augmentation cystoplasty, the neoplasia development risk increases and most of these develop in the neobladder or anastomosis line. Only two cases of VA developing from the native bladder mucosa have been reported.

Sarcomatoid Type of Paratesticular Malignant Mesothelioma in a Dry-Cleaning Worker Exposed to Asbestos and Diagnostic Value of WT-1.

Of the 3 major histologic types of malignant paratesticular mesothelioma (MPM) (epithelial, sarcomatoid, and biphasic), many cases of epithelial and biphasic mesothelioma have been reported in the literature. Pure sarcomatoid MPM is the least common but the most aggressive of the 3 major histologic types of mesothelioma cells. It is limited to only 2 cases in the literature The sarcomatoid type of MPM can be confused clinically and histologically with true sarcomas because it is rarely seen.

Clear cell variant of solid pseudopapillary neoplasm of pancreas diagnosed by fine needle aspiration: A case report and review of the literature.

Solid pseudopapillary neoplasm (SPN) of the pancreas is a rare tumor of uncertain malignant potential, predominantly affecting young adult females. We report a case of clear cell variant of SPN, which was diagnosed by fine needle aspiration biopsy. The aspirate was highly cellular and exhibited delicate branching papillary structures with central capillaries covered with several layers of plasmacytoid tumor cells.

Which factors predict upper urinary tract deterioration in overactive neurogenic bladder dysfunction?

Objectives: To determine whether bladder histopathologic changes, detrusor leak point pressure (DLPP), disease duration, and preoperative catheterization time can predict for upper urinary tract (UUT) deterioration in patients with overactive neurogenic bladder dysfunction (ONBD).

Methods: A total of 39 patients (7 women and 32 men) with ONBD who were treated with augmentation cystoplasty were included in the study. The patients had undergone perioperative full-thickness bladder biopsies during augmentation cystoplasty.

Primary granulocytic sarcoma of the urinary bladder: case report and review of the literature.

We report a case of granulocytic sarcoma of the urinary bladder, with no evidence of hematologic involvement. The patient was initially misdiagnosed and was treated with chemotherapy for transitional carcinoma grade 3. Despite this treatment, the clinical features of the patient progressed, and a repeated biopsy yielded the correct diagnosis.
