Histoplasmosis has emerged as an important opportunistic fungal infection in immunocompromised patients. Histoplasma is a dimorphic fungus that primarily involves lung and the environmental reservoir is soil. Although several cases of histoplasmosis have been reported in India but cytological diagnosis was made in a few cases. We are presenting two cases of(More)
Histoplasma is a dimorphic fungus that primarily involves the lungs and the environmental reservoir is soil. It has emerged as an important opportunistic fungal infection in immunocompromised patients. Six cases of histoplasmosis with variable clinical presentations diagnosed either on cytology or histopathology are discussed - three were HIV-positive. The(More)
Accurate estimation of the cost of a software minimizes the risk for the software development process. Applicability of the different cost estimation models is very crucial as the information required for the implementation of such models is imprecise and vague. In order to increase the accuracy of the model, it is proposed to introduce the concept of(More)
Cysticercosis is a condition that occurs when man is infected with larvae of Taenia solium. Oral cysticercosis is a rare event, and it represents difficulty in clinical diagnosis. A case of oral cysticercosis in 11 year old girl is presented which complained of painless swelling for 6 months. A FNAC was performed which revealed bluish pink fibrillary(More)
Rosai-Dorfman Disease (RDD) or Sinus Histiocytosis with Massive Lymphadenopathy (SHML) is a rare disorder typically manifesting as enlarged lymph nodes with or without systemic involvement. These cases are often clinically misdiagnosed as lymphoma. Recognising this entity to distinguish it from lymphoma and other causes of histiocytosis is important because(More)
Oncocytic carcinoma is an extremely rare neoplasm of the salivary gland, with only a few cases reported in literature till date. We report the occurrence of this rare lesion in lip in a 43-year-old female presenting with a progressively increasing swelling for which excision was done. Fine needle aspiration was done and the smears revealed tumor cells with(More)
Transferrin, the major iron binding protein in human plasma transports iron to various tissues. The first step in cellular iron uptake is binding of transferrin complex to the cell surface membrane by specific molecule known as transferrin receptors. Transferrin receptors are found in limited sites in normal tissues, in contrast, the receptors are widely(More)
Cyclodextrins are oligosaccharides having outer hydrophilic surface and central hydrophobic cavity. These agents form inclusion complexes with poorly water-soluble drugs; hence they show an important implication for use in ophthalmics because of their applications in solubilising and stabilising the ocular drugs. Most of the drugs being used in ophthalmics(More)
