Management: Treatment should focus on the internal problems and include proctocolectomy or a permanent terminal ileostomy, if there are more than 20 polyps are present. The cutaneous cysts are treated as any other cyst with various types of surgical intervention. Osteomas may require resection if they interfere with function.
Osteoid Osteoma

The symptoms and imaging are suggestive of osteoid osteoma. Osteoid osteoma accounts for 13.5% of all benign tumours. Most of those affected are young; approximately one-half are in the 2nd decade of life at presentation. The most common symptom is bone pain, which often worsens at night. The pain is thought to be mediated by release of prostaglandins, which helps explain the relief experienced after prostaglandin inhibitors such as NSAIDs such as aspirin.
Benign tumors

Osteomas of the skin are small round to oval nodules with all characteristics of normal bone. They are very rare in the distal digit.227 They may present merely as a splinter hemorrhage extending from the site of the osteoma to the hyponychium.228 Subungual osteomas can only be suspected radiographically.

Paranasal sinuses osteomas are relatively uncommon, slow-growing, osteogenic tumors [1]. Osteomas are the most commonly encountered neoplasm of the frontal sinus and the frontal bone accounts for 80% of all paranasal sinus osteomas [2]. The formation of an intracranial tension pneumatocele secondary to a frontal sinus osteoma has been infrequently publicized [2,3]. Osteomas are usually asymptomatic, but may sometimes cause complications such as headache, cerebrospinal fluid (CSF) fistula, meningitis, ptosis, diplopia and pneumocephalus. Our case is probably the first case describes isolated frontotemporal dementia as presenting features of the intra-parenchymal pneumocephalus secondary to ethmoid sinus osteoma [4].
Computed tomography and magnetic resonance imaging of an unusual intraconal orbital osteoma

The mechanisms that trigger the formation of mature bone within soft tissues remain unclear. One hypothesis is based on remote trauma being an initiating factor, but not all cases of osteomas present a previous history of trauma.2,5 A second hypothesis postulates that primitive mesenchymal cells from connective tissues might originate osteomas. In the rare cases of intracranial extraskeletal osteomas, it has been suggested that they might come from pluripotent cells of the meninges.2,4–7 In the context of the orbit, one might believe that pluripotent cells of connective orbital tissues or optic nerve meninges could be responsible for the appearing of extraskeletal osteomas.
Types of orbital osteoma – A descriptive analysis

Osteoma is a slow-growing tumour that is benign in nature and primarily occurs in the cavities and bones of the middle third of the face. Osteoma of the paranasal sinuses is discovered only as a coincidental radiological finding and is generally asymptomatic. Primary intra-orbital involvement of osteomas is extremely rare,9 evident from the record review of patients presenting at our institution with orbital osteoma who were diagnosed based on clinical as well as radiological findings and confirmed by histopathology over a period of 13 years and showing a prevalence of 2.3% only.
