This tumor included a tiny proportion of signet-ring cells. These can be very "signety" and fool you into seeking a gastric primary that does not exist. I have even seen such a case present primarily as a signet ring cell carcinoma of the endometrium on a D&C specimen. It took quite a while and not a few phone calls to get to the bottom of that!

What happened to this poor eel? Is this an inflamed injury, or a tumor?
I'm on YouTube too with lots of underwater videos

Tumor On Board!
I have had my fair share of ear issues.
When I was 2, I was diagnosed with a parotid gland tumor. Parotid glands are located in each cheek over the jaw in front of the ears. Thankfully it was benign, but even though I was only 3 I can still remember flashes of that time. They actually took a film of the procedure and slides as this operation was uncommon for its time (1975). I am trying to get in touch with records where my doctor was at the time (and up until a few years ago, now retired) to see if I can get a copy of at least the slides.
Fast forward to when I was about 5 and I started having pain in front of my left ear and could no longer eat anything solid. My parents took me to see Dr. Camp and they ran some tests and poked around. They found that the tumor hadn’t come back but there was a lot of scar tissue and they decided the scar tissue needed to be removed.
A week later it was the morning of check-in and my Mom took me to a local Fred Meyer (Grocery / Home Supply / Toys / Hardware) and let me pick out a stuffed animal to take to the hospital… I picked out a Scooby Doo stuffed toy (My Mom still has the warn-out Scooby). Off to the hospital we went… Checked in and I slept there that night… surgery was the next morning.
Surgery went okay, though when they tried to put the gas mask over my mouth/nose I freaked out. I still don’t like that… but now they give you all kinds of shots before they do the gas.
The cool thing is they put me in a room for recovery right by one of the kitchens… I couldn’t eat solid food but I could have ice cream, Jell-O and pudding and all I had to do was knock on the wall. I did have a roommate, an older person who insisted on watching soaps and more “adult themed” night shows. I spent a week in the hospital. This would have been surgery #2 and I would be having 2 more surgeries.
I still have a lot of issues with that ear and in the picture above you can see the scar; it runs down right in front of my ear and makes a line down towards my neck behind the earlobe. One issue is that the gland was damaged during one of the surgeries and instead of salivating on the inside it comes out through my skin… Not all the time but when I am eating something that produces a lot of saliva, it goes a bit crazy. I often get asked if I am hot or eating something hot as it looks like I am sweating. When I brought this up to Dr. Camp about 12 years ago he said not to worry and I was probably unique with the issue.
Since I was about 14 I had an issue with that gland becoming infected and getting hard… my newest doctor said it’s probably an infection due to saliva getting stuck in the glad and becoming infected. Solution is the have the gland removed but in that there are risks. Main risk is that there are a ton of facial nerves that run along that glad and there is a really good chance those could be damaged and I would be left with uncontrollable twitching (anywhere on my left side) or drooping face, also on the left side. I keep thinking about having it done as when it becomes infected it’s very painful and I can’t eat anything.

49 y/o male who presented with dull aching pain and discomfort in his right testicle of several weeks' duration. Examination revealed a hard nodule in his testis. Serum tumor markers (AFP, beta-hCG, LDH) were within reference ranges. Radical orchiectomy was done. Sections showed a pure classical seminoma (4.5 cm in largest dimension) with foci of necrosis.

A 28-year-old man presented with a 9-year history of chronic ulcerative colitis (UC), treated initially with Asacol and more recently with Imuran, and rectal polyps. Biopsies one year ago were diagnosed as adenoma-like low grade dysplasia in association with chronic active colitis. The patient subsequently underwent a transanal excision of the irregular folds, and the tissue sections were read as markedly inflamed hyperplastic polyps with superficial mucosal ulcerations and no evidence of dysplasia or malignancy. The patient now has recurrence of a circumferential nodular mucosal fold in the rectum that is concerning for malignancy, in addition to a continuous inflammatory process involving the rectum and left colon. The right colon is relatively free of inflammatory disease. Biopsies were obtained.

Large, polypoid, tan neoplasm within the lumen of a major bronchus producing bronchial obstruction and obstructive pneumonia.
Palisading of columnar cells at the periphery of tumor trabeculae.
The term atypical carcinoid may be somewhat misleading since it may give the impression of a low grade of malignancy when if fact these are fully malignant neoplasms in which distant metastases are present in about 20% of patients at presentation and the disease free survival after 10 years is about 50%. An alternate name - neuroendocrine carcinoma grade 2 - has been suggested. I believe that this is preferable to atypical carcinoid but others are unwilling to accept this terminology.

This tumor is just larger than the size of a pencil eraser. I'm unsure if it's actually a tumor or part of my dermis that was removed, but the texture and everything under it that made concerned is now gone. These photos document several days of black salve application and the resulting eschar and hole left behind (which will fill in the next week or two).
My family is medically inclined and I am cautious not to use black slave in any sensitive or dangerous area of my body. Be aware the dangers of salve are very real... it can create complications that may result in severe disfigurement and death.

Partially regressed germ cell tumor with residual teratoma: This cluster of glandular structures lined by columnar epithelium was present at the periphery of one of the cysts.
another cancer story... australian doctors are helping this young girl by donating their time to remove this tumor from her face.
Multilocular mucinous cystic tumor surrounding a bronchus. The locules are lined by atypical mucinous epithelium.
The classification of these rare neoplasms is difficult and controversial. There appears to be a spectrum of mucinous cystic tumors ranging from those that are obviously benign (benign epithelium and no tumor invasion into surrounding lung) to those that exhibit invasion into surrounding lung tissue and are, therefore, malignant. In between is a group of neoplasms that exhibit epithelial atypia but no tumor invasion into lung tissue and the malignant potential of these is uncertain. This case appears to fall into that category. Focal cyst rupture with extravasation of mucin into surrounding lung tissue may occur with all types of mucinous cystic tumors.
the balloon guy at the hutch picnic made this... i think he might have taken the whole cancer center thing a little too far.
This subpleural lesion consists mostly of pigmented scar tissue with gray-tan tumor seen predominantly at the periphery.The visceral pleura overlying the tumor is retracted due to traction by underlying scar tissue. This is a good example of what has been called "scar carcinoma". In almost all cases of this type the scar is not a pre-existing lesion but rather represents a desmoplastic reponse to the tumor cells. The basal visceral pleura is involved by tumor
Very sad.
UPDATE: Probably not a tumor but a Hydrocyst, see...
