Interesting case: Bronchial washing of a middle aged male with acute respiratory failure. Any guesses as to what this critter was identified as? First pic: ThinPrep Second pic: GMS special stain. #Cytopath #cytopathology #pathtwitter #microbiology

Unique Oral Presentations of Deep Fungal Infections: A Report of Four Cases by Vimi S. Mutalik, Caroline Bissonnette, John R. Kalmar & Kristin K. McNamara rdcu.be/b6Wir #HeadNeckPathol #HNPJ #HeadandNeckPath #Pathology #ENTPath #PathologyTweet

70 M with R humeral mass. FNA is loaded with Mott cells (containing innumerable Russell bodies)! Russell bodies are round cytoplasmic hyaline inclusions frequently seen in BM aspirates in multiple myeloma. #FNAFriday #cytopathology #PathTwitter #HemePath #PathRes

56 F with FNA of vertebral lesion. Smears showed basaloid cells palisading around classic metachromatic extracellular matrix spheres (hyaline globules). These findings were consistent with metastatic adenoid cystic carcinoma. #FNAFriday #PathRes #cytopathology

Olfactory Neuroblastoma : Malignant neoplasm arising from neuroectodermal olfactory cells. Lobular arrangement of primitive neuroblastoma cells. Small round blue cells with small, uniform nuclei. +ve: Calretinin, S100 and GFAP, -ve: Desmin, Myogenein, p63, FLI1. UTMB Pathology

“Stranger Things”, which you may never see again! Thyroid with a primary Langerhans Cell Histiocytosis (LCH). Please don’t ask what the FNA was called.

A Bronchogenic Cyst Masquerading as a Tongue Mass By Zahra Aldawood, David J. Moyer & Sook-Bin Woo rdcu.be/cf9H0 #HeadNeckPathol #HNPJ #HeadandNeckPath #Pathology #ENTPath #PathologyTweet

Newly described rare tumor of the head and neck. Over a third of reported cases occur in pediatric patients! Similar to other spindle cell RMS, MyoD1 appears to be the most sensitive myogenic IHC marker #pedipath #bstpath #entpath

Finally, after 4 years, the AFIP Fascicle on Tumors of the Salivary Glands is out! Thanks to great coauthors! #HeadandNeckPath #HeadNeckPathol ARP Press J. Bish #PathologyTweet

Nice example of a common entity. Warthin tumour involving the parotid...one of the most eye catching tumours histologically....bilayered oncocytic epithelium lining cystic spaces with a surrounding lymphoid stroma. #salivaryglandtumours #headandneckpathology #oralpathology

Almost a "Mercedes-Benz" sign - Branching capillaries floating in a pool of colorful mucin from the very RARE, "Mucoepidermoid Carcinoma" of the breast. Cytopathology is truly FASCINATING. I guess we all agree!
