Case Studies
A case study reported in 2009 involving Chrysomya bezziana included a 65-year-old woman with skin cancer. The woman had facial squamous cell carcinoma (SCC). A tumor developed as an ulcer on her left cheek and the woman did not keep the wound covered. When the ulcer began to spread, she did not seek any treatment for the myiasis for two years. Ultimately, the case was handled by removal of the larvae using forceps until about 60 larvae were removed. The patient was discharged and two days later returned to have 10 more larvae removed from her face. Infestation of Chrysomya bezziana in cancerous wounds is very rare and most of the cases deal with SCC among elderly patients.
Many cases among humans involve infestation of the oral cavity. According to the Communicable Diseases Watch newsletter, 11 of the 21 infestations in Hong Kong between October 2002 and December 2004 were in the oral cavity.
Another case study, reported in 2008, involved a 9-year-old boy in Indonesia. He was hospitalized due to maggots inside his right ear. The maggots were removed, and while the patient was recovering, it was noticed that the right eye was red. Upon examination, a maggot was found inside a lesion in the bulbar conjunctiva, and this maggot was then removed.

Famous quotes containing the words case and/or studies:
“A woman’s whole life is a history of the affections. The heart is her world: it is there her ambition strives for empire; it is there her avarice seeks for hidden treasures. She sends forth her sympathies on adventure; she embarks her whole soul on the traffic of affection; and if shipwrecked, her case is hopeless—for it is a bankruptcy of the heart.”
—Washington Irving (1783–1859)
“Even if one studies to an old age, one will never finish learning.”
—Chinese proverb.
