6	Head/Neck	55YOF with a left nasal mass.	Slide 1
7	GU	A 91-year-old underwent excision of a left hydrocele sac, which revealed nests and cords of infiltrative epithelioid cells.  In focal areas, these cells were associated with an accompanying myxoid/desmoplastic stromal response.	Slide 1
8	GU	A 74-year-old female underwent a left partial nephrectomy for a 3.9 cm mass.  This tumor showed infiltration into the perinephric fat and metastatic involvement of the ipsilateral adrenal gland.	Slide 1

20	Pulmonary	A 65-year-old woman with a history of right breast cancer (2015) and left lower lobe pulmonary adenocarcinoma (2020) presents with a new 2.6 cm right upper lobe lung mass with hilar and mediastinal lymphadenopathy and multiple liver lesions. FNA of the liver lesion is provided.	Slide 1
21	Cytology	A 49-year-old woman presented to clinic with complaints of recurrent chest pain. CTA showed a right lower lobe lung mass with bulky ipsilateral hilar and mediastinal lymphadenopathy. Endobronchial ultrasound (EBUS)-guided fine needle aspiration was performed. A representative cell block is shown.	Slide 1
22	Cardiac	A 66-year-old patient with a 4 cm PET-avid right atrial mass. A representative section of the surgically resected specimen is provided.	Slide 1
23	Hempath	* 61-year-old male who presented 4 years prior with relapsing polychondritis.  * Prior BM biopsies had no definitive diagnosis, no clonal abnormality; presumably autoimmune-related. * He has been treated with steroids and rituximab. * He has become progressively transfusion dependent and refractory to therapy. * CBC: Hb 7.4, MCV 109, WBC 6.9, plt 67. Differential: 85% PMN, 13% lymphs and 2% monocytes. * A BM biopsy is performed and is from 5 years ago.	Slide 1
24	Hempath	* 44-year-old female who has BRCA2 mutation and had “spots” on her skin for 15 years. * She has no itching, rashes, ulceration or any other symptoms. * CT scan is normal. * CBC: Hemoglobin 11.7, MCV 99, platelet 247, WBC 5.8 with ANC 3.0.	Slide 1
25	Hempath	* 71-year-old female with a PMHx of diabetes mellitus type 2, hypertension, hyperlipidemia, and GERD. * She was on vacation and developed progressive fatigue and somnolence associated with significant exercise intolerance. * Her symptoms did not abate after several weeks and she appeared pale and exhausted to her family members, so she was taken to the emergency room. * In the ER, her CBC showed hemoglobin 6.2 gm/dL, MCV 106, white blood cells 70.3K and platelets 55K. * A bone marrow was performed.	Slide 1
26	Neuro	This 52 year-old female patient presented after a fall. Head imaging studies revealed a heterogenous, peripherally-enhancing mass centered in the right parietal lobe.	Slide 1
27	Neuro	This 19 year-old male patient presented with new-onset seizures. Head imaging studies revealed a large, heterogenous mass centered in the right fronto-temporal lobe, which is associated with prominent mass effect.	Slide 1
28	Neuro	This 73 year-old male patient presented with headaches. Head imaging studies revealed a dura-based, homogenously enhancing mass overlying the left fronto-parietal lobe.	Slide 1
