Background Cysticercosis is a zoonotic disease. It is caused by the larval form of the pork tapeworm Taenia solium. This disease is a public health problem in a country like India, but its incidence is underestimated. With the advent of fine needle aspiration cytology with rapid on-site evaluation, early detection of this disease is possible, especially when the lesion is in anatomically approachable superficial locations. Case report We had four cases of cysticercosis diagnosed by fine needle aspiration cytology with on-site evaluation using toluidine blue stain, followed by Giemsa and Papanicolaou stain. Our cases included three Hindu male patients of age 30 years, 23 years, 17 years and an 26 year old Hindu female. Conclusion Fine needle aspiration cytology diagnosis of cysticercosis can be easily made provided the reporting cytologist is aware of the morphological criteria. Rapid on-site evaluation can further help in taking additional material and caution during staining process.

Rhinosporidiosis is caused by Rhinosporidium seeberi, a protist of class Mesomycetozoea, which comprises mostly uncultivable aquatic microbes at the animal-fungal boundary. It chiefly affects the mucous membranes of the nose, oropharynx and nasopharynx. It also involves many rare sites and may become disseminated to occur in a generalized form. Soil and water act as a reservoir for the organism. Rhinosporidiosis of the parotid duct is rare and there are very few reported cases in the Indian literature and world-wide. Our case report of a 20-year-old female presenting with facial swelling, the duct cyst was excised and submitted for histopathological examination which confirmed the diagnosis of rhinosporidiosis due to the presence of sporangia and endospores in the wall of the cyst.

Aneurysmal bone cysts are infrequent in the craniofacial region. These cysts are non-neoplastic, expansile, and osteolytic in nature. Since these cysts are not lined by epithelium, they are considered as pseudocysts. Clinicopathological features and biological behavior of these cysts are enigmatic as they mimic various other pathogenetic lesions and two third of these cysts are associated with other bone pathology. Aim of the present paper was to report a case of aneurysmal bone cyst in 40-year-old female patient encountered in left mandibular posterior region which was surgically treated with hemimandibulectomy. The post-operative period was uneventful. Furthermore, emphasis was given to discuss its etiopathogenesis, clinicopathological variants, and other pathologies associated with this cyst.

Objective: Oral Submucous Fibrosis (OSF) is a precancerous condition and is mainly associated with the chewing of areca nut. This study was undertaken to correlate the etiological factors (duration, frequency, style and chewing habit) associated with OSF with clinical grading and histological staging. Methodology: A total of 50 clinically and histopathologically diagnosed cases of OSF were included in the study. Detailed clinical examination of each patient was done; emphasizing on their habit. Clinical grading and histological staging of each case was done and the data was recorded in a prescribed format. Statistical analysis was done using chi-square test. Result and observation: A total of 50 subjects were studied, with a male to female ratio of 7.3:1 with age range of 20-30 year. Gutkha-chewing habit alone was identified in 46% of subjects and those associated with gutkha and tobacco were 33.3% with a mean ± S.D =32 ± 11.51. Conclusion: The widespread habit of chewing gutkha plays a major role in the development of Oral Submucous Fibrosis than any other habit. The duration and frequency of its use and type of areca nut product has effect on the incidence and severity of OSF.

Introduction: Cyclin D1 oncogene is a key regulator of cell cycle progression associated with various human malignancies. Aim: To establish the prognostic significance of cyclin D1 in oral squamous cell carcinoma (OSCC) and to correlate its association with clinicopathological parameters. Materials and Methods: A retrospective study was carried out on 50 previously histopathologically diagnosed, formalin-fixed, paraffin embedded (FFPE) tissue samples of OSCC. Immunohistochemical analysis was performed in 50 cases of different grades of OSCC using a commercially available monoclonal anti-cyclin D1 antibody. Statistical Analysis Used: All the compiled data was statistically analyzed using Chi-square and Mann-Whitney test. P values of
