Case of the Week 556

This week's case was donated by Dr. Neil Harris and Dr. Stacy Beal. The patient is an infant with a history of tracheobronchomalacia and "eosinophilia" on prior bronchoscopy. A routine complete blood count was negative without evidence of peripheral eosinophilia. The following structures were seen on a Giemsa-stained bronchoalveolar lavage specimen using the 100x objective. They have a diameter of 1-3 micrometers. Identification?

The nematodes superficially resembles Dirofilaria sp.

Curschman spirals

After further examination, I believe Anon is right, there is no organization nor tissue like structure on the object. This leads me to think that the object is more compatible with mucus strands.

Not a parasite.
Likely a mucous plug, ie. Curschman spiral

Spirali di Curschmann

Agree with my predecessors. Appears to be a mucus like structure, compatible with curschmann spirals and the clinical case of the child.
