Cysts of the oral cavity are among the most commonly encountered biopsy specimen in histopathology. Shear categorized the cysts associated with maxillary antrum under four subheadings - mucocoele, retention cyst, pseudocyst, and postoperative maxillary cyst (PMC). PMC is also known as surgical ciliated cyst, postoperative paranasal cyst, or respiratory implantation cyst. Although it constitutes 20% of oral cysts in Japan, it is quite rare in the other parts of the world. Herewith, we report a case of a 65-year-old female who presented with the complaint of palatal swelling and having a history of maxillary sinus surgery 30 years ago.

Mucocele-like lesions (MLLs) of the breast are rare neoplasms characterized by dilated, mucin-filled epithelial ducts or cysts that can rupture and expel their contents into the surrounding stroma. They are frequently associated with atypia, dysplastic change, and, more recently, pre-malignant and malignant conditions like atypical ductal hyperplasia, ductal carcinoma, invasive carcinoma, or mucinous carcinoma. The malignant potential of MLLs is often challenging to determine from the initial histologic evaluation of a core-needle biopsy due to copious mucin and low cellularity. Therefore, at initial presentation, MLLs should be surgically excised and thoroughly evaluated for malignancy. In this paper, we present a rare case of an MLL and explore the radiology, histology, carcinogenic potential, diagnostic evaluation, and suggested management of the condition.

The soft tissue tumor lipoma is quite frequent. Although it is the most mesenchymal tumor of the trunk and proximal regions of the extremities, it is quite uncommon to find it on the oral mucosa, accounting for just 1% to 5% of benign oral tumors. There is no specific location that is more prone to lipoma development in the mouth. Some frequent sites are the tongue, buccal mucosa, and the mouth's floor. A Yellowish mass with no symptoms is the normal clinical appearance. In most cases, the overlaying epithelium is unharmed, and superficial blood vessels may be seen passing through and around the tumor. The differential diagnosis might also include granular cell tumors, neurofibroma, traumatic fibroma, and diseases of the salivary glands (mucocele and mixed tumor). Herein a detailed case of a 28-year-old woman with a right-sided lower-lip oral lipoma is presented in this paper.

The mucocele of the appendix can be described as an obstructive dilatation of the appendix by an intraluminal accumulation of mucus. A 60-year-old diabetic male patient presented with chief complains of pain in right lower abdomen for the past 2 months which was dull in nature, not associated with fever, vomiting, diarrhea, constipation, or any urinary complains. Contrast-enhanced computed tomography (CECT) of the abdomen revealed appendiceal lumen distended, filled with fluid collection. There was abrupt narrowing seen at its junction with cecum. Features were suggestive of appendicular mucocele. The patient was taken up for exploratory laparotomy, and a distended turgid appendix, around 4 cm in diameter with dilated cecum, was found. Ileocecal resection was done followed by ileo-ascending colon side-to-side anastomosis using staplers. The histopathological examination report revealed an R0 resection. The patient was followed up for 3 years postoperatively with CECT of the abdomen and a colonoscopy yearly. There was no evidence of any recurrence in the follow-up.

BACKGROUND
The pathogenesis of gallbladder (GB) mucoceles in dogs is unknown. It has been proposed that hyperlipidemia could impair GB motility and contribute to GB mucocele formation.
HYPOTHESIS/OBJECTIVES
The objective of this study was to compare GB motility in dogs with hyperlipidemia to control dogs using ultrasonography. We hypothesized that hyperlipidemic dogs will have decreased GB motility compared with controls.
ANIMALS
Twenty-six hyperlipidemic and 28 healthy, age-matched control dogs were prospectively enrolled.
METHODS
Cholesterol and triglyceride concentrations were measured in all dogs. Hyperlipidemia was defined as hypercholesterolemia (>332 mg/dL) and/or hypertriglyceridemia (>143 mg/dL) using a biochemical analyzer. Ultrasound was performed before feeding, and 60 and 120 minutes after ingestion of a high fat diet. Gallbladder volumes (GBV) and ejection fractions (EF) were calculated.
RESULTS
Hyperlipidemic dogs had significantly larger GBVs (ml/kg) before feeding and 60 minutes after feeding of 1.2 (0.4-7.5; P = .008) and 0.6 (0.1-7.2; P = .04) compared with controls 0.6 (0.2-2.6) and 0.4 (0.1-1.9), respectively. Severely hyperlipidemic dogs had significantly larger GBV at baseline, 60 minutes, and 120 minutes of 1.7 (0.6-7.5; P = .03), 1.3 (0.4-7.2; P = .02), and 1.3 (0.2-8.2; P = .04), respectively compared with mildly hyperlipidemic dogs. EFs at 60 and 120 minutes between controls, hyperlipidemic, and severely hyperlipidemic were all 0.3 at 60 minutes and 0.5, 0.3, and 0.3 at 120 minutes, respectively which were not statistically different.
CONCLUSIONS AND CLINICAL IMPORTANCE
Hyperlipidemia leads to GB distention in dogs which could lead to retention of bile and gallbladder disease.

Oral extravasation mucoceles are among the most widely recognized submucosal lesions which are usually a result of trauma involving salivary glands and their ducts. This paper reports a case of a 40-year-old female patient with a chief complaint of a painless swelling on the lower lip since 6 months. Upon a provisional diagnosis of mucocele, surgical excision was carried out. Histopathological examination revealed a mucus extravasation cyst having lumen filled with unique mucinous globular structures similar to a rare variant of appendiceal mucocele, myxoglobulosis.

Review
Mucocele of the paranasal sinuses is a slowly expanding benign lesion developing when there is impeded physiological drainage of the mucous produced by the epithelial lining of the paranasal sinuses, at the sinus ostium, which is an opening that connects the sinus to the nasal cavity. Aetiologies of ostial occlusion include infection, allergy, trauma, previous surgery, benign neoplasm (osteoma or fibrous dysplasia), and malignant or metastatic tumours. Mucoceles commonly develop in the frontal sinus (70-80 per cent), followed by the ethmoid (25 per cent), frontoethmoidal (10-14 per cent), and maxillary (three per cent or less) sinuses. The most common manifestations in these cases are ocular oedema, proptosis (22-83 per cent), and diplopia (28 per cent). Due to these ocular signs and symptoms, the optometrist may be first in line managing paranasal sinus disease patients, reducing the risk of permanent damage. A case report and review of frontoethmoidal mucocele will be discussed in this report, to include the role of the optometrist in its management and treatment.
