Bladder Mass

Extraskeletal osteosarcoma is a malignant mesenchymal soft tissue tumor without attachment to the bone, and is able to produce osteoid or cartilaginous matrix. This entity accounts for 1% of all soft tissue sarcomas. Thus far, less than 35 cases of bladder osteosarcomas have been reported in the literature. These tumors are associated with very poor prognosis. We report a case of primary osteosarcoma of the urinary bladder presenting with intermittent hematuria, dysuria, and right flank pain. Contrast-enhanced computed tomography scan of the abdomen, pelvis, and chest revealed a bladder mass and pulmonary metastases with specks of calcification.

Abstract Extraskeletal osteosarcoma is a rare malignant mesenchymal soft tissue tumor without attachment to the bone and is able to produce osteoid or cartilaginous matrix. Rendering a definitive diagnosis may pose a challenge particularly in a resource-limited setting. We report a case of primary osteosarcoma of the urinary bladder presenting with hematuria, dysuria and positive history of schistosomal contact. Computed tomography intravenous urogram revealed a large heterogeneous mass at the right superolateral aspect of the urinary bladder. Morphological evaluation of the biopsy and a minimal panel of immunohistochemical antibodies of vimentin and cytokeratin 20 ruled out potential differentials and thus confirmed the diagnosis of osteosarcoma.

Cytoskeletal System

The amphibian urinary bladder has been used as a ‘model’ system for studies of the mechanism of action of antidiuretic hormone (ADH) in stimulating transepithelial water flow. The increase in water permeability is accompanied by morphological changes that include the stimulation of apical microvilli, mobilization of microtubules and microfilaments and vesicular membrane fusion events . It has been shown that alterations in the cytosolic calcium concentrations can inhibit ADH transmembrane water flow and induce alterations in the epithelial cell cytomorphology, including the cytoskeletal system . Recently, the subapical granules of the granular cell in the amphibian urinary bladder have been shown to contain high concentrations of calcium, and it was suggested that these cytoplasmic constituents may act as calcium storage sites for intracellular calcium homeostasis. The present study utilizes the calcium antagonist, verapamil, to examine the effect of calcium deprivation on the cytomorphological features of epithelial cells from amphibian urinary bladder, with particular emphasis on subapical granule and microfilament distribution.

Antibody Labeling

Protein kinase C (PKC) isozymes, when activated, are translocated to particulate membrane fractions for transport to the apical membrane surface in a variety of cell types. Evidence of PKC translocation was demonstrated in human megakaryoblastic leukemic cells, and in cardiac myocytes and fibroblasts, using FTTC immunofluorescent antibody labeling techniques. Recently, we reported immunogold localizations of PKC subtypes I and II in toad urinary bladder epithelia, following 60 min stimulation with Mezerein (MZ), a PKC activator, or antidiuretic hormone (ADH). Localization of isozyme subtypes I and n was carried out in separate grids using specific monoclonal antibodies with subsequent labeling with 20nm protein A-gold probes. Each PKC subtype was found to be distributed singularly and in discrete isolated patches in the cytosol as well as in the apical membrane domains. To determine if the PKC isozymes co-localized within the cell, a double immunogold labeling technique using single grids was utilized.
