Biphasic synovial sarcoma with epithelial predominance reminiscent of adenocarcinoma: a diagnostic challenge.

Synovial sarcoma (SS) is a rare tumour of unknown origin with peak incidence between 10 and 35 years. Although it arises in juxta-articular location, SS is a misnomer and has no true relationship with synovium. In this case report, we present an elderly female patient with a long-standing history of thigh mass which was initially misdiagnosed as metastatic adenocarcinoma deposits on fine needle aspiration cytology, and again misdiagnosed as malignant adnexal skin tumour on core needle biopsy and referred for further management.

Spontaneous Partial Vanishing Cytomegalovirus Pseudotumour of Colon in an Immunocompetent Patient.

Cytomegalovirus (CMV) pseudotumour of the gastrointestinal tract, is a rare benign entity which is treated with antiviral medications and known to resolve spontaneously in a few cases. This is a case report of a 58-year-old man who presented with right lower quadrant abdominal pain. Contrast enhanced computerized tomography of abdomen and pelvis showed apple core lesion involving proximal transverse colon, ceacum, ascending colon, ileoceacal valve and terminal ileum.

Chiari III Malformation: a rare case with review of literature.

The Chiari Malformation is a neural tube defect involving the posterior cranial fossa and the hind brain, characterized by herniation of the posterior fossa contents below the level of the foramen magnum. Four types were described by Hans Chiari in the late 19th century. Of these, Type III is exceedingly rare.

Androgen receptor expression and DNA content of paraffin-embedded archival human prostate tumors.

Background: Androgen receptors (AR) are expressed in human prostate cells and immunohistochemistry has been used for qualitative analysis of AR expression in prostate tumor cells. Quantitative and multiparametric analysis of receptor expression could be of diagnostic and prognostic value in the management of patients on antiandrogen therapy. Multiparametric flow cytometric methods have been developed for analysis of hormone receptor expression and DNA content in nuclei isolated from formalin-fixed/paraffin-embedded human solid tumors.
