calcific body

An artefact seen in tissue sections, caused by dystrophic calcification and often found within necrosis, as in fibrocaseous nodules of the lungs of various aetiologies—e.g., granulomatous processes or malignancy. The hyphae-like elements are the result of calcification of collagen fibres, which may fragment horizontally, resulting in a septum-like appearance.

To our surprise, we found the cytology smears contained characteristic parasitic elements such as scolices, hooklets, homogeneous eosinophilic-laminated membrane [Figure 1], and calcospherules; a diagnosis of hydatid cyst in parotid gland was made.
Parasitic fragments may comprise bluish, fibrillary structures, sometimes with honeycombing, calcospherules, tegument thrown into rounded wavy folds, scolex with hooklets, and hyaline membrane surrounding it [9-11].
Histological findings demonstrated a sparganum with thick eosinophilic tegumentum and subtengumental calcospherules (Fig.
