ABSTRACT
Isolated pulmonary cysticercosis is a rare manifestation of human cysticercosis which mainly affects central nervous system, skeletal muscles, eyes and subcutaneous tissues. Pulmonary involvement is usually a part of disseminated disease and mainly presents as bilateral pulmonary nodules. We report a rare case of isolated pulmonary cysticercosis presenting as lung cyst with pleural effusion. The diagnosis was made on pleural fluid cytology and cell block preparation. Herein we wish to recapitulate the importance of cell block as a diagnostic aid for parasitic infections, where morphological features and architectural patterns are as clearly discernable as in histopathology.

Isospora belli, a coccidian parasite usually causes a self limiting illness of acute onset with fever, diarrhoea and colicky pain in a normal host. In immunocompromised patients human isosporiasis becomes chronic. We report a case of a malnourished 9 year old female child who presented with complaints of loose stools, nausea, vomiting and weight loss for the past three months. Stool examination revealed immature oocysts of Isospora belli. The patient was successfully treated with TMP-SMX.

Ziehl Neelsen (Z-N) stain is the commonly used procedure for demonstration for AFB. A Simple cold stain technique and Simplified concentration technique were compared with the conventional methods on 1484 sputum samples over a period of 3 months. A positivity rate of 9.3% was observed on direct microscopy with an increase in the yield by 30% after concentration. It was observed that the simple cold staining and simplified concentration are viable alternatives for demonstration of mycobacteria in busy clinical laboratories.
