Intranodal palisaded myofibroblastoma originating from retroperitoneum: an unusual origin.

Background: Intranodal palisaded myofibroblastoma is one of the primary mesenchymal tumours. The inguinal region is the commonest site of this rare tumour. As there are only about 55 such cases reported in the literature, the precise aetiology and pathogenesis have yet to be explained adequately.

Cytology of Hürthle cell neoplasms of thyroid gland.

Hürthle cell neoplasms (HCN) are an uncommon group of tumors of the thyroid gland. Fine needle aspiration cytology (FNAC) is an important diagnostic tool in solitary nodules of the thyroid gland. A 5-year retrospective analysis of all cases diagnosed as HCN on cytology was performed and correlated with the corresponding histopathology wherever available.

Partial duplication of head--a rare congenital anomaly.

Duplication of notochord results in rare congenital anomalies like double headed monsters, with or without trunk/limb duplication, depending upon the extent of notochordal abnormality. Here we describe the morphological abnormalities in a case of partial duplication of cranial structures with fusion of the two. Autopsy findings suggest that the bifurcation of the neural tube took place around 4th to 6th week of gestation.

Collagenous bodies in endometriotic cysts.

A 4-yr retrospective analysis of cases diagnosed as pelvic endometriotic cysts based on clinical, radiological, and cytomorphological features was collected and analysed. Out of 15 cases, only 3 cases showed the presence of endometrial glands/stroma in the aspiration smears. However, 12 of them showed the presence of oval/petal-shaped structures throughout the smear ranging in size from 40 to 70 micro in maximum dimension.

Leiomyosarcoma of the urinary bladder: a diagnostic challenge in urine cytology.

Most of the available data in the literature describe the cytomorphological features of exfoliated malignant epithelial cells in urine. There are no established diagnostic features that characterize the morphology of exfoliated malignant mesenchymal tumor in urine. Here we highlight the problems in the diagnosis of these groups of tumors.

Indian file pattern of adenocarcinoma cells in effusions.

Objective: To determine the prevalence of the Indian file pattern of adenocarcinoma cells in malignant serous effusions.

Study Design: Twenty-five malignant and 10 benign effusion samples were selected. Clinical data, including the sites of the primary neoplasms, were noted.

Aplastic anaemia following varicella infection with coexistent microfilaremia of Wuchereria bancrofti--a case report.

Filariasis is a common public health problem in various regions of Indian subcontinent. There are many reports describing detection of microfilaria in different organ systems. There are limited number of reports available describing the presence of microfilaria in bone marrow.

Basal cell adenoma-an unusual presentation.

Basal cell adenoma is an uncommon epithelial neoplasm of the salivary gland most commonly arising in the parotid glands. We report a case of basal cell adenoma of the minor salivary gland presenting as a slowly progressing, large parapharyngeal mass. Histopathology revealed a well-encapsulated mass with characteristic histomorphology.

Giant-cell-rich myxoma of right atrium. An ultrastructural analysis.

Myxoma is the commonest primary tumor of the heart, arising more frequently in the left than the right atrium. Here, we report a case of right atrial myxoma, arising close to the entry of the inferior vena cava, which is rich in multinucleated giant cells. No glandular elements were identified.

Apoptosis in breast cancer.

Objective: To evaluate apoptotic rates on fine needle aspiration (FNA) samples of infiltrating duct carcinoma of the breast and to determine whether cytologic grading improved with consideration of the apoptotic rate in comparison with histologic grading.

Study Design: We studied 35 women who underwent mastectomy following an FNA diagnosis of infiltrating ductal carcinoma. Concordance between cytologic and histologic grades was calculated.

Cytological grading, apoptosis, and Bcl-2 protein expression in breast cancer.

A prospective study was conducted on 27 cases of infiltrating duct carcinoma of breast diagnosed by fine-needle aspirate cytology (FNAC), subjected to mastectomy following the FNA diagnosis. Cytological grading, Bcl-2 score, and quantification of apoptotic cell count were done on FNA material. Next, the carcinomas were graded on the corresponding histopathological sections.
