Squamous cell carcinoma of the anal sac in five dogs. (1/21)Tumors of the perianal area of dogs are common and include multiple tumor types. Whereas perianal adenomas occur often, adenocarcinomas of the apocrine glands of the anal sac occur less frequently. A review of the literature revealed no reports of squamous cell carcinomas arising from the epithelial lining of the anal sac. Squamous cell carcinomas originating from the lining of the anal sac were diagnosed in five dogs. Microscopically, the tumors consisted of variably sized invasive nests and cords of epithelial cells displaying squamous differentiation. Four of the five dogs were euthanatized because of problems associated with local infiltration by the tumors. In the fifth dog, there was no evidence of tumor 7 months after surgical removal, but further follow up was not available. (+info)
Possible coding for recognition of sexes, individuals and species in anal gland volatiles of Mustela eversmanni and M. sibirica. (2/21)With a combination of solvent extraction and gas chromatography-mass spectrometry, we found eight new compounds in the two sympatric Mustela species, M. eversmanni and M. sibirica. These compounds had not been detected by headspace sampling with solvent desorption. Two of the newly detected compounds are nitrogen-containing compounds, indole and o-aminoacetophenone and the remaining are sulfur-containing volatiles. By comparing same and opposite sexes between the two Mustela species, we found that qualitative differences in the anal gland secretion are most likely to be used to code for information about species, corresponding to the idea of digital coding. In the Siberian weasel (M. sibirica), both presence or absence of sex-specific compounds (Z-2-ethyl-3-methylthietane only in females) and relative abundance of some compounds between males and females could be used to code for information about sex, corresponding to the idea of digital and analog coding, respectively. In the steppe polecat (M. eversmanni), only quantitative differences provided the possibility for inter-sexual communication. Thus coding for information about sex appeared to be digital. Coding for individual information could also be either digital or analog or both through the presence or absence of certain compounds and/or the difference in the relative abundances of certain compounds among individuals. Comparing with other Mustela spp., we failed to find a congruence between the chemical composition of anal gland secretions and the phylogenetic relationship among the species in this genus. (+info)
Differential activation of glomeruli in the ferret's main olfactory bulb by anal scent gland odours from males and females: an early step in mate identification. (3/21)Peripheral anosmia was previously found to disrupt sex discrimination and partner preference in male and female ferrets. Here we show directly that volatile anal scent gland odourants from male and female ferrets activated overlapping but distinguishable clusters of glomeruli located in the ventral-caudal portion of the main olfactory bulb (MOB) of breeding ferrets of both sexes. No glomerular activation was seen in the accessory olfactory bulb (AOB). The profile of MOB glomerular activation induced in oestrous females by male anal scents was very similar to that induced by direct contact with a male during mating, and oestrogen treatment failed to alter the profile of glomerular activation induced in ovo-hysterectomized females by male anal scents. In rodents, 'atypical' MOB glomeruli, which have dense acetylcholinesterase (AChE) activity in the neuropil, may be activated by body odours from conspecifics. No such AChE-staining 'atypical' glomeruli were found in the ferret's MOB, suggesting that in this carnivore they do not constitute a subset of MOB glomeruli that respond to body odourants. In ferrets of both sexes, volatile body odourants that are detected by the main as opposed to the vomeronasal-AOB accessory olfactory system may play a critical role in mate identification. (+info)
Metastatic anal sac adenocarcinoma in a dog presenting for acute paralysis. (4/21)A 4-year old, female spayed terrier was referred for hind end paresis that rapidly progressed to paralysis. Spinal radiographs revealed vertebral collapse and bony lysis. Myelography confirmed spinal cord compression and surgical exploration found an extradural soft tissue mass. Metastatic anal sac adenocarcinoma was diagnosed at postmortem examination. (+info)
Anal sac gland carcinoma in a cat. (5/21)A perianal mass in a 15-year-old domestic shorthair cat with a history of a firm, painful swelling in the left ventrolateral perianal region was surgically excised and submitted for light microscopic evaluation. Histologically, this was a poorly demarcated, unencapsulated, multilobulated neoplasm that invaded surrounding perirectal skeletal muscle bundles. Lobules were composed of sheets and acinar arrangements of cuboidal to round neoplastic epithelial cells with scant to moderate eosinophilic to amphophilic cytoplasm and a round or oval nucleus with coarse chromatin. Mitotic figures were 2 per 40 x objective field. Acinar lumina sometimes contained eosinophilic proteinaceous material or cell debris. These microscopic features are consistent with anal sac gland carcinoma. This is the second report of this neoplasm in a cat. (+info)
Adjuvant electrochemotherapy for incompletely excised anal sac carcinoma in a dog. (6/21)Canine anal sac gland carcinoma (ASGC) is a frequently described neoplasm that is highly aggressive and can frequently lead to metastatic spread. In this paper, we describe the successful treatment of an incompletely excised ASGC by using cisplatin selectively driven within the tumor cells by trains of biphasic pulses. The dog received two courses of electrochemotherapy 14 days apart. Neither systemic nor local toxicities were detected during the whole course of therapy. The dog is still in complete remission after 18 months. Electrochemotherapy is a safe and efficacious adjuvant therapy for ASGC and warrants further investigation in order to standardize its protocols. (+info)

There are several types of anal gland neoplasms, including:
1. Anal gland adenomas: These are benign tumors that grow slowly and typically do not spread to other parts of the body.
2. Anal gland adenocarcinomas: These are malignant tumors that can invade nearby tissue and spread to other parts of the body.
3. Squamous cell carcinomas: These are malignant tumors that arise from the squamous cells that line the anus.
4. Melanocytic neuroendocrine tumors: These are rare tumors that arise from the pigment-producing cells of the anal glands.
The symptoms of anal gland neoplasms can include:
1. Pain or discomfort in the anus
2. Bleeding from the anus
3. Itching or discharge from the anus
4. A lump or mass near the anus
5. Difficulty passing stools
The diagnosis of anal gland neoplasms is typically made through a combination of physical examination, imaging studies such as CT scans or MRI, and biopsies. Treatment options can include:
1. Surgery to remove the tumor
2. Radiation therapy to destroy cancer cells
3. Chemotherapy to kill cancer cells
4. Immunotherapy to boost the body's immune system against cancer
The prognosis for anal gland neoplasms depends on the type and stage of the cancer, as well as the patient's overall health. In general, early detection and treatment improve the chances of a successful outcome.
There are several types of sweat gland neoplasms, including:
1. Apocrine sweat gland adenoma: This is a benign tumor that typically affects the axillae (armpits) and groin area. It can become large and cause discomfort or pain.
2. Eccrine sweat gland carcinoma: This is a malignant tumor that arises in the eccrine sweat glands, which are found throughout the body. It is rare and usually affects the skin of the arms, legs, or trunk.
3. Apocrine sweat gland carcinoma: This is a rare and aggressive type of cancer that develops in the apocrine sweat glands. It typically affects the skin of the axillae (armpits) and groin area.
4. Sebaceous gland carcinoma: This is a rare and aggressive type of cancer that develops in the sebaceous glands, which are found in the skin. It can occur anywhere on the body, but is most common on the face, scalp, or torso.
The symptoms of sweat gland neoplasms vary depending on the location and type of tumor. They may include:
* A lump or swelling in the affected area
* Painless or painful lumps that can become large
* Redness, swelling, or bleeding of the skin
* Discharge or odor from the affected area
* Fever or chills
If you suspect you may have a sweat gland neoplasm, it is important to seek medical attention. Your healthcare provider will perform a physical examination and may order diagnostic tests, such as imaging studies or biopsies, to determine the cause of your symptoms. Treatment options for sweat gland neoplasms vary depending on the type and location of the tumor, but may include surgery, radiation therapy, or chemotherapy.
1. Parvovirus (Parvo): A highly contagious viral disease that affects dogs of all ages and breeds, causing symptoms such as vomiting, diarrhea, and severe dehydration.
2. Distemper: A serious viral disease that can affect dogs of all ages and breeds, causing symptoms such as fever, coughing, and seizures.
3. Rabies: A deadly viral disease that affects dogs and other animals, transmitted through the saliva of infected animals, and causing symptoms such as aggression, confusion, and paralysis.
4. Heartworms: A common condition caused by a parasitic worm that infects the heart and lungs of dogs, leading to symptoms such as coughing, fatigue, and difficulty breathing.
5. Ticks and fleas: These external parasites can cause skin irritation, infection, and disease in dogs, including Lyme disease and tick-borne encephalitis.
6. Canine hip dysplasia (CHD): A genetic condition that affects the hip joint of dogs, causing symptoms such as arthritis, pain, and mobility issues.
7. Osteosarcoma: A type of bone cancer that affects dogs, often diagnosed in older dogs and causing symptoms such as lameness, swelling, and pain.
8. Allergies: Dog allergies can cause skin irritation, ear infections, and other health issues, and may be triggered by environmental factors or specific ingredients in their diet.
9. Gastric dilatation-volvulus (GDV): A life-threatening condition that occurs when a dog's stomach twists and fills with gas, causing symptoms such as vomiting, pain, and difficulty breathing.
10. Cruciate ligament injuries: Common in active dogs, these injuries can cause joint instability, pain, and mobility issues.
It is important to monitor your dog's health regularly and seek veterinary care if you notice any changes or abnormalities in their behavior, appetite, or physical condition.
