Myospherulosis
Myospherulosis, also known as spherulocytosis, is a foreign body-type granulomatous reaction to lipid-containing material and blood. It may be seen in various settings including: 
Fat necrosis. Malignancy, e.g. renal cell carcinoma. Placement of topical tetracycline in a petrolatum base into a surgical site. The resultant histopathologic pattern is most unusual and initially was mistakenly thought to represent a previously undescribed endosporulating fungus. See also
