Foray of Cytologically Diagnosed Intramuscular Sarcocystosis- A Rarity.

Sarcocystosis is an uncommonly encountered zoonotic coccidial protozoal infestation of human beings. The sarcocystis species is known to produce intestinal and muscular infestations in humans. We report a rare case of a 35-year-old female with an intramuscular swelling in the lumbar region diagnosed cytologically as "Intramuscular Sarcocystosis" and subsequently confirmed on histopathology. This case highlights the role of fine needle aspiration cytology in the identification of Sarcocystis and its role in differentiating it from other intramuscular parasites which is of immense value in precise diagnosis and appropriate patient management.
