? negatively birefringent - look like urate crystals
Charcot-Leyden crystals (residue of eosinophils). Occasionally seen in stool of patients with hookworms or amebiasis.
Well said
The needle like objects appear crystalline. Most likely urate crystals.

Pineapple crystals
I also think that it is monocot crystals, such as pineapple, asparagus, etc. To differentiate them from fatty acid crystals, we can heat the slide: if they are monocot they remain, if they are fatty acid, fat droplets would form.

Agree. Fruits or vegetables Crystals can be confused with Charcot-Leyden crystals.
Agree with Florida Fan.
Charcot Leyden crystals. A breakdown product of Eosinophils. So this could be an indication of a potential helminth infection, or their presence could be due to another inflammatory reason (e.g allergy)
Cristaux de Charcot leyden
Fruit crystals. Very slender and long. Not looking like the Charcot Leyden ones.
After further search, I believe these are fruit crystals as illustrated in medical-labs.net. More than likely pineapple crystals.
