We reported the case of a 21-year-old female
patient from Sakarya, Turkey, who visited the local hospital with pain in the
right costo-lumbar region. She also complained of irritation in the vagina,
dysuria, polyuria, hematuria, vomiting and diarrhea. During her stay in the
hospital five grayish-brown larvae, approximately 3 mm in length, were isolated
from her urine. The larvae were identified as the fourth stage of the moth fly
Psychoda albipennis (Taylan-Ozkan et al. 2004).
The case of an eight-year-old boy with
hyper-eosinophilia who presented with a swelling under his right armpit that had
persisted for more than four weeks, was reported. A second-stage larva of
Wohlfahrtia magnifica was found, leading to the diagnosis of cutaneous
myiasis. Following removal of the larva, the clinical and hematological
manifestations returned to normal. Diagnosis of myiasis should always be kept in
mind in the event of clinical signs of furuncular lesions, which may be
accompanied by eosinophilia (Tuygun et al. 2009).
A 33 year old woman living in Elad, a small city
about 25 km east of Tel Aviv in the middle of a rural area, had suffered for
years from sinusitis and asthma for which she was treated with antibiotics and
prednisone. Recently she was not permitted to take part in nature trips and had
not left the country for the last 2 years. On 20 May 2010, she observed two
small living larvae that were expelled from her nose while sneezing. The larvae
were sent to a neighboring hospital but were lost. On 2 October 2010, a third,
larger, larva was discharged from her nose while sneezing, and was brought to
our laboratories for examination. The larva was black in color and had shrunk,
indicating that it had been dead for some time before it was expelled from the
nasal cavity. It was identified as the third stage of Oestrus ovis
(Mumcuoglu & Ron, 2010).
A retrospective observational study of patients
who presented with myiasis was conducted between 1999 and July 2014 in the
post-travel clinics in Israel. Data regarding exposure history, travel duration,
clinical presentation, treatment, and parasitological identification were
collected and analyzed. Among 6,867 ill returning Israeli travelers, 1,419 (21%)
had a dermatologic complaint, 90 (6.3%) of them were diagnosed with myiasis.
Myiasis was acquired in Latin America by 72 (80%) patients, mainly (54%) in the
Madidi National Park, Amazonas Basin, Bolivia; 18 cases (20%) were acquired in
Africa. Of the 18 African cases, 15 were identified as infested by C.
anthropophaga, while all the infestations caused by C. rodhaini
were acquired in Ghana, while all cases from South America were diagnosed as
Dermatobia hominis. In 76% of cases, manual extraction was sufficient
to remove the larva; 24% required surgical intervention. Despite the fact that
most patients did not receive antibiotic treatment, only one developed secondary
infection, upon partial removal of the larva (Lachish et al. 2015).
