Morphology of cystic structures seen in leprosy biopsy suspensions kept at cooler temperatures.

Cystic structures were seen in good numbers in biopsy suspensions obtained from leprosy patients and kept at cooler temperature. The structures were found arranged in singles, clusters or straight lines. In clusters, small round structures were seen surrounding a large spherical body. The small cystic bodies appeared empty, the medium sized bodies showed fine particles while the large ones showed spherules in and around them. It appears that the seed structure of the cycle emerges from the large spherical bodies.
