Primary pleural serous carcinoma of mullerian origin-Report of a rare case.

Mullerian tumor arising from pleura is a rare occurrence and under-reported in medical literature. We hereby present such a case in a 47 years old female who presented with pleural effusion. Pleural biopsy revealed a papillary tumor with mild-to-moderate nuclear atypia.

Atrophic kidney-like lesion: A rare benign entity and mimicker of thyroid follicular-like carcinoma of kidney.

Atrophic kidney like lesion (AKLL) is a recently described benign entity with only 14 cases reported so far. Genitourinary Pathology Society proposed inclusion of AKLL as a provisional entity in 2021. It mimics thyroid follicular-like carcinoma of kidney as it has a follicular architecture.

Primary Myoepithelial Carcinoma of the Clivus: A Rare Presentation.

Myoepithelial tumor (MET) of bone is an unusual tumor of uncertain differentiation and histogenesis. Although its presence in various bones has been reported sparsely, the presentation in clivus as primary myoepithelial carcinoma (MEC) has never been reported. They resemble their salivary gland counterparts morphologically and immunohistochemically, but harbor distinct molecular phenotype.

Transformation of tomato with a bacterial codA gene enhances tolerance to salt and water stresses.

Genetically engineered tomato (Lycopersicon esculentum) with the ability to synthesize glycinebetaine was generated by introducing the codA gene encoding choline oxidase from Arthrobacter globiformis. Integration of the codA gene in transgenic tomato plants was verified by PCR analysis and DNA blot hybridization. Transgenic expression of gene was verified by RT-PCR analysis and RNA blot hybridization.

Intraabdominal hydatid cyst: a case report.

Background: Hydatid disease is caused by Echinococcus granulosus, endemic in cattle and sheep-raising regions of the world such as Central Europe, South America, Australia, New Zealand and South Africa. Although hydatid disease is more common in liver and lung, it also affects brain, kidney, spleen and muscle. We present a case of intraabdominal hydatid cyst, diagnosed by fine needle aspiration cytology, producing an indentation of the liver, which is uncommon.

Utility of fine needle aspiration cytology in mediastinal lesions: a clinicopathologic study of 1617 cases from a single institution.

Objective: To study the distribution, prevalence and cytomorphologic features of mediastinal lesions and assess the utility of fine needle aspiration cytology (FNAC) in such lesions by correlating with clinical, laboratory and imageologic parameters.

Study Design: A retrospective study was performed of mediastinal lesions that were referred for ultrasonographic/computed tomography-guided FNAC during the years 2001-2006. Correlation was done wherever possible using the following parameters: histology, bone marrow, imageology, tumor markers, cytology, immunohistochemistry, antecedent history and regression after therapy.

Pulmonary metastases of recurrent intracranial hemangiopericytoma diagnosed on fine needle aspiration cytology: a case report.

Background: Meningeal hemangiopericytoma (HPC) is a rare neoplasm. It is closely related to hemangiopericytomas in systemic tissues, with a tendency to recur and metastasize outside the CNS. Only a few case reports describe the cytomorphologic appearance of these metastasizing lesions, most having primary tumor in deep soft tissues.

Active necrotizing cerebral vasculitis in systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is a multisystemic disease with varied clinical manifestations. Focal cortical brain infarcts and CNS infections are the most common neuropathological features reported in most studies. This report describes a 32-year-old woman who had repeated episodes of strokes over 5 years.

Intracranial mycotic aneurysm due to Aspergillus species.

Intracranial true mycotic aneurysms are uncommon and usually fatal. We report two patients with basilar mycotic aneurysms due to Aspergillus species following surgical interventions. Both patients had subarachnoid hemorrhage and diagnosis was made at autopsy only.

Histoplasmosis as a cause of nodular myositis in an AIDS patient diagnosed on fine needle aspiration cytology. A case report.

Background: Histoplasmosis, extrapulmonary or disseminated, with positive HIV serology is an indicator of AIDS. Infection by Histoplasma capsulatum (HC) has been found on fine needle aspiration cytology (FNAC) in the lung, breast, adrenal, gastrointestinal tract, lymph nodes, subcutaneous tissues and other sites. We could not find any reports of isolated nodular myositis caused by HC and diagnosed on FNAC.
