This week's case was generously donated by Dr. Paul Valenstein. It is an eyelid biopsy from a 6-year old African child. Diagnosis?

The structural morphology is compatible with myasis. Given the location is Africa, one of the agent to be considered would likely be Cordylobia anthropophaga though I am not so sure.
I think that is a great thought. Though, I am accustomed to fabric overlay for exposure to Cordylobia-- I imagine a wet sheet or towel may have been sufficient. The eye sometimes is a target of direct fly deposited larva such as Woltharia spp. I standby to be further educated. Cheers,
Great case! Could this be sparganosis or some other sort of cestode infection? There are structures that somewhat resemble calcareous corpuscles in the stroma of the organism...
Every week I will post a new Case, along with the answer to the previous case. Please feel free to write in with your answers, comments, and questions. Also check out my image archive website at http://parasitewonders.com. Enjoy!
