Correlations of aldehyde dehydrogenase-1 (ALDH1) expression with traditional prognostic parameters and different molecular subtypes of breast carcinoma.

Background And Aim: Breast cancer, a heterogeneous disease, is the most common cause of cancer-related death in women worldwide. Despite considerable developments in treatment modalities, a subset of patients with advanced-stage breast carcinoma display poor prognosis. Breast cancer heterogeneity and risk of recurrence could be explained with the help of cancer stem cell hypothesis.

Cytological and histological correlation of granular cell tumor in a series of three cases.

Granular cell tumor (GCT) is an uncommon soft tissue tumor characterized by proliferation of cells with granular eosinophilic cytoplasm. We came across three such tumors, one in the tongue, one in the chest wall, and one in the right deltoid region, which were referred for fine-needle aspiration cytology. On cytological examination, the first two cases were diagnosed as GCT, and the mass in deltoid region was suggestive of proliferative myositis.

Clinicopathological study of rhinosporidiosis with special reference to cytodiagnosis.

Background: Rhinosporidiosis is a chronic infective disorder caused by Rhinosporidium seeberi. It usually presents as a soft polypoidal pedunculated or sessile mass. Nose and nasopharynx are the commonest sites, followed by conjunctiva, maxillary sinuses, penis, urethra.

Pattern of cancer occurrence in rural population of West Bengal--a hospital-based study.

Incidence of cancer in India is lower than in the West and the commonly affected sites are very different. Cancers of the upper alimentary and respiratory tracts (oral cavity, pharynx, larynx) contribute more than half of the cancers in men and about a quarter in women. Indigenous habits of chewing and smoking seem to be primarily responsible for the high incidence of these cancers.

Cytodiagnosis of glomus tumor.

Glomus tumors are uncommon, with an estimated incidence of 1.6%. Cytological descriptions of this tumor are few.

Computed tomography-guided fine needle aspiration cytology of thoracic mass lesions: A study of 57 cases.

Background: Computed tomography (CT)-guided fine needle aspiration cytology (FNAC) is regarded as a rapid, safe, and accurate diagnostic tool in examining thoracic mass lesions for the last three decades.

Aims: To assess the role of CT-guided FNAC in thoracic mass lesions, to analyse the results, and to compare the results with other studies.

Materials And Methods: Fifty-seven patients were studied over a year (July 2007 to June 2008) for their age, sex, and topographic distribution, pleural infiltration (based on CT findings), and cytological diagnoses.

Primary pleomorphic sarcoma of the ovary with rhabdomyosarcomatous differentiation.

A 49-year-old patient presented with a right ovarian mass, which, on microscopy, showed to consist of haphazardly oriented large pleomorphic cells with abundant cytoplasm. Periodic acid Schiff stain was positive but negative with diastase digestion. Immunohistochemical staining with Desmin showed intense cytoplasmic positivity in almost all the cells.

Cutaneous metastasis from follicular variant of papillary thyroid carcinoma: a case diagnosed on cytology.

A 40-year-old woman presented with a scalp swelling. A careful clinical examination revealed a left-sided deep-seated thyroid nodule. Fine needle aspiration from both sites disclosed a microfollicular architectural pattern on Giemsa stain and pale nuclei with nuclear grooves on Papanicolaou stain, indicating the possibility of follicular variant of papillary thyroid carcinoma with metastasis to the scalp.

Recurrent and aggressive chondroblastoma: a case report.

Recurrent chondroblastoma with pulmonary and palatal metastasis is a rare occurrence. We report the cytological and histological findings of such a case in a 33 years old male, where the primary diagnosis of metastatic chondroblastoma was made on FNAC, which was later confirmed on histopathology. The present case highlights that, some chondroblastomas do exist, that are capable of pursuing a malignant course.
