Osteomas are benign osteogenic tumors that are
composed of cancellous or compact bone. They are
usually sessile tumours composed of dense sclerotic,
well-formed bone projecting out from the cortical
surface. They commonly occur in skull and facial
bones, however, excluding the maxillary sinuses,
the maxilla is a rare site for osteomas. Therefore,

... They usually occur in the mandible bone or nasal and paranasal sinuses (frontal, ethmoidal, maxillary, and rarely sphenoidal). Osteomas rarely occur in maxillary bones like the hard palate and zygomatic arch [7][8][9][10][11][12][13][14] . ...
Heterotopic ossification is the formation of bone tissue at an
abnormal site. The ossification of soft tissue outside the skeletal
system can occur anywhere and can be found in mucosal tissues.
This is the first case report of an osteoma mucosalis affecting
the nail bed. We also reviewed the heterotopic ossification and
calcification of cutaneous and mucosal sites in the PubMed,
Scopus, and Google Scholar databases.

... 3,4 The paranasal sinuses and the mandible are most commonly affected sites in the head and neck region. 5,6 Palatal osteomas are relatively uncommon 7,8 and are often asymptomatic. The osteomas in palatal region can cause functional impairment and minimal facial disfigurement. ...
... Radiographically, peripheral osteomas present as an oval to round, well circumscribed radio-opaque mass, and attached to the adjacent cortical bone with a broad base or pedunculated with a narrower stalk. 8 Jaw bones exostoses as they do not grow beyond puberty, patients presenting with long standing and progressively growing bony masses should be examined for other lesions to rule out any associated syndromes. Asymptomatic osteomas or jaw bone exostoses are usually managed conservatively until they impede with function or esthetics. ...
El osteoma es una lesión osteogénica benigna, derivado de hueso compacto o esponjoso. Se caracteriza por ser de crecimiento lento y aparece con más frecuencia entre los 20 y los 50 años de vida, con una prevalencia mayor en hombres con respecto a las mujeres. Clínicamente asintomáticos, los podemos encontrar en la región craneofacial, particularmente en los senos paranasales y la mandíbula, y pueden presentarse de tres formas: central, periférica y extraósea, siendo más comunes los solitarios, a diferencia de los múltiples que están relacionados con el síndrome de Gardner. El tratamiento de los osteomas es quirúrgico cuando causan complicaciones. Los estudios por imágenes, como la radiografía panorámica y la TCHC, son las modalidades de mayor uso para determinar la ubicación, la extensión y las relaciones anatómicas de la lesión. Las características imagenológicas pueden presentarse como una excrecencia ósea de hueso compacto, esponjoso o mixto. El conocimiento de esta lesión nos permitirá tener mejores propuestas diagnósticas.
Osteomas are benign, slow growing, usually sessile osteogenic tumors of unknown etiology. They arise from proliferation of either cancellous or compact bone. They can be central, peripheral or extra-skeletal based on their origin from endosteum, periosteum or extra-skeletal soft tissue respectively. They are commonly found in the skull and facial bones, the most common site in the maxillofacial region being paranasal sinuses. Among the jaw bones the most common site is the mandible. The hard palate is a rare site for such osteomas with a very few cases reported in literature. We report a case of large pedunculated peripheral osteoma of the hard palate in a 38 year old male. The tumor was excised with no recurrence after 3 years followup.
