Lymphatic filariasis is endemic in India and Southeast Asia. Detection of microfilaria is infrequently reported during cytological evaluation of various lesions or body cavity fluids. Presence of microfilaria in pleural fluid cytology is very rare finding even in endemic areas. Few cases of accidental finding of microfilaria have been reported in association with malignant pleural effusion. But pleural effusion of filarial origin is extremely rare manifestation. Here we report a classical case of microfilaria in pleural fluid cytology...

Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy, accounting for 70%-80% of all thyroid malignancies. It is biologically indolent and has an excellent prognosis. Variations in histopathologic patterns are known to influence prognosis and often result in a diagnostic dilemma. We report an unusual case of a 35-year-old female with papillary carcinoma of a thyroid isthmus showing anastomosing channels on histopathology, a distinctive pattern that has not been described in PTC. Similar to tumor cells, the lining cells of these channels were also positive for thyroid transcription factor 1, thyroglobulin, and cytokeratin-19 and negative for CD34 and CD31...

Chronic hyperplastic candidiasis (CHC), earlier known as candidal leukoplakia, is a variant of oral candidiasis that classically presents as a white patch on the commissures of the oral mucosa and it is mostly caused by Candida albicans. Clinically, the lesions are usually asymptomatic and regress after appropriate antifungal therapy and correction of the underlying cause. If the lesions are untreated, a small portion may develop dysplasia and later progress into carcinoma. The purpose of this article is to report a case of CHC in a 57-year-old male patient with a significant smoking habit, who presented with a thick, nonscrapable, brownish-white coating on the dorsum of the tongue for 9 years...

PURPOSE: Resistance to carbapenems due to carbapenemases has been increasingly noticed in Enterobacteriaceae. Clinical and Laboratory Standards Institute (CLSI) has recommended the latest Carba NP (CNP) test as a confirmatory test for carbapenemase production in Enterobacteriaceae. Low sensitivity of disk diffusion (DD) and modified Hodge test (MHT) may result in missing out of resistant strains which can adversely affect clinical management. The present study compares three phenotypic tests - CNP test, DD, and MHT for detection of carbapenemase production...
