Sialadenoma papilliferum (SP) classified under the ductal papillomas by the WHO is a rare benign tumor of minor salivary glands. It is a rare lesion of salivary glands predominantly affecting the minor glands. It has characteristic exophytic and endophytic clinical growth pattern. Histopathologically, it is characterized by papillary projections supported by fibrovascular connective tissue core and infiltrated with mixed inflammatory cells. The ductal lining epithelium of double-layered cells of luminal layer of tall columnar cells and a basilar layer of small cuboidal cells shows additional papillary projections into the lumen. We report a case of SP of mid palate.
Lipoma is called the “universal tumor” or the “ubiquitous tumor” as it occurs anywhere in the body where fat is found. Intraosseous lipoma is a rare lesion that constitutes not more than 0.1% of bone tumors. There are only a few reported cases of intraosseous lipoma of the maxilla in the literature. The diagnosis of intraosseous lipoma of the maxilla may be a challenge, due to its rarity and clinical similarity with many other radiolucent lesions. Therefore, histopathological examination is mandatory. The radiolucent nature and mature adipose tissue admixed with the bony trabeculae confirms the diagnosis of intraosseous lipoma. Here, we report a case of intraosseous lipoma of the left maxillary tuberosity in a 52-year-old male patient.
Eosinophilic granuloma (EG) is a rare histiocytic disorder resulting from clonal proliferation of Langerhans cells. Eosinophilic granuloma, the most benign of the three entities of Langerhans cell histiocytosis, may be multiple or solitary. This lesion can affect any bones but commonly involves the mandible when the jaws are affected. It is difficult to make a correct diagnosis on it without proof of a pathological diagnosis, which correlates with the diverse clinical and radiographic presentations of EG in the jaws. This report describes a case of unifocal EG of the mandible occurring in a 6-year-old boy whose initial presentation led to confusion of any solitary bony lesion. A final diagnosis of EG was established after histopathological examination of the biopsy specimen.
Dermoidcyst are usually seen as a slow growing benign painless mass. The treatment of choice for dermoid cysts is surgical enucleation. The most common location in the head and neck region is the external third of the eyebrow. Sublingual location is very rare. They are benign lesions arising from entrapment of epithelial rests during embryogenesis. Due to its malignant potential, understanding about this lesion is very essential. With the help of radiological investigation like MRI the precise location, extension and relationship of the cyst with the surrounding structures can be identified. Here we represent a case of sublingual swelling in a twenty year old female patient who was treated by surgically excision under general anesthesia. To conclude with proper radiological investigation dermoid cyst in the floor of the mouth can be managed by surgical excision.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
