Peripheral osteoma of the nasal bone after laser treatment: A case report.

INTRODUCTION: Peripheral osteoma, which arises from the periosteum, commonly develops in the head and neck region and is found frequently in the mandible, maxilla, and paranasal sinuses. However, osteoma of the face, especially from the nasal bone, is quite rare. PATIENT CONCERNS: A 34-year-old female visited our outpatient department with a small mass on the nose. She had n laser treatment of nevus at the same spot 14 years before, and it had enlarged slowly since 10 years before. DIAGOSIS: Computed tomography scan revealed a 0.7 × 0.5 cm sized radio-opaque tumor of the nasal bone. INTERVENTIONS: Under general anesthesia, surgical excision was performed through a transcolumellar and infracartilaginous incision. The excised tumor was a 0.7 × 0.5 cm sized hard mass. OUTCOMES: Biopsy confirmed it as a peripheral osteoma. After tumor removal, structural stability of nasal framework including bone and cartilage was maintained, and symmetry of the nasal dorsum was acquired. CONCLUSION: Chronic osteoma can compress the abutting structures. In the case of the nose, either structural instability or asymmetry can occur. By applying open rhinoplasty techniques, postoperative scars could be hidden and additional correction of the affected structure could be carried out if necessary. As a result, the surgeon can achieve the functional and esthetic outcomes simultaneously.

Ivory osteoma of the craniofacial skeleton.

The authors describe the clinical presentation, investigation, and surgical management of two cases of benign ivory osteoma of the craniofacial skeleton. In the first case, a bony mass located over the frontal region had become a cosmetic burden to the patient, and she requested removal with minimal morbidity. Accordingly, an endoscopic procedure, with minimal access incisions located behind the hairline, was devised. In the second case, the patient, a Jehovah's Witness, presented with a long history of slowly enlarging bony masses over the maxilla and in the pterygopalatine space. She finally requested surgical intervention when the symptoms of pain related to fifth nerve compression at the foramen ovale became intolerable. Key aspects of the preoperative and perioperative management strategies used to avoid blood transfusion are detailed, as is the surgical approach, which included a bicoronal scalp flap with temporary removal of the zygomatic arch and the coronoid process. Finally, the etiology, histology, and natural history of ivory osteomas are discussed.

Tumor-induced osteomalacia: long-term follow-up of two patients cured by removal of their tumors.

Two patients with mesenchymal tumors had osteomalacia associated with marked hypophosphatemia and renal phosphate wasting. Their serum calcium and parathyroid hormone levels were normal. The first patient also had aminoaciduria and glucosuria in addition to phosphaturia. Both patients were treated with very large doses of vitamin D2 and phosphate without improvement in the osteomalacia or normalization of the serum phosphate. Complete removal of a low-grade fibrosarcoma in the second patient and removal of an ossifying fibroma in the first patient resulted in a cure in both patients despite no further therapy with vitamin D or phosphate. The excessive aminoaciduria and glucosuria of the first patient also remitted. During a 14-year follow-up period, there has been no evidence of tumor recurrence, hypophosphatemia, or osteomalacia in either patient. The levels of 1,25-dihydroxycholecalciferol remain within the normal range in both patients.
