Osteoma is a benign tumour consisting of mature bone tissue. It is an uncommon lesion that occurs mainly in the bones of the craniofacial complex. Only a few cases involving the condylar process have been reported. An osteoma of the left condyle causing limited mouth-opening in a 32-year-old Malaysian Chinese female is reported here to alert the practitioner to consider this lesion as a diagnos...

Craniofacial osteomas may be located either superficially or intraosseously on any bone of the cranium or face or within a paranasal sinus. Osteomas within the paranasal sinus account for 0.01% to 0.43% of patients; of these, up to 80% occur in the frontal sinus. An osteoma of maxillary sinus is extremely rare. We describe a rare case of osteoma of a 56-year-old Asian woman in the maxillary sinus.

Osteoid osteoma is a benign bone tumor that rarely affects the carpal bones. Because of its nonspecific presentation in the wrist, it remains a diagnostic challenge. We report an unusual case of osteoid osteoma in the capitate where the diagnosis was delayed and the presentation was that of an aggressive natured lesion with considerable functional incapacitation. Diagnosis was made by computed ...

Osteoma is the most common benign tumor of the nose and paranasal sinuses. Most commonly seen in the frontal sinus, it is less common in the ethmoid and maxillary sinuses. This tumor may be discovered incidentally on radiographs, or may grow enough to produce symptoms. Rarely, complications occur at its location near the orbit and anterior skull base. We present a case of frontoethmoid osteoma ...

Becker's nevus is a relatively common acquired focal epidermal melanotic hypermelanosis usually found in the region of the shoulder girdle of young men. Various skeletal malformations and cutaneous dermatoses have been reported in Becker's nevus. Osteoma cutis is a rare disorder characterized by compact bone formation in the dermis or subcutaneous tissue. Secondary ossification on nevi has been...

Radiofrequency ablation (RFA) therapy is recognised as a safe and effective treatment option for osteoid osteoma. This case report describes a 27-year-old man who underwent computed tomography (CT)-guided percutaneous RFA for a femoral osteoid osteoma, which was diagnosed based on his clinical presentation and CT findings. The patient developed worsening symptoms complicated by osteomyelitis af...

An 18-year-old girl presented with an osteoid osteoma in the ulnar side of the cortex of the distal radius extending into the distal radioulnar joint. The osteoid osteoma was removed from the distal radius at surgery. The patient’s symptoms were dramatically improved the day after surgery. A high concentration of prostaglandin E2 (PGE2) was seen in the joint and surrounding soft tissues, and cy...

Juxta-articular, subperiosteal osteoid osteomas arising around the ankle are unusual. Tumors arising on the neck of the talus commonly produce symptoms mimicking monoarticular arthritis. Patients are usually treated for arthritis or ankle sprain, which often leads to a delay in definitive diagnosis. Here we present a case of osteoid osteoma of neck of talus which was presented as ankle pain. It...

We report herein the case of an 18-year-old man who underwent endoscopic resection for an osteoid osteoma in the seventh cervical facet joint. The patient had experienced right neck pain for approximately one year, but no neurological abnormalities were noted. Cervical magnetic resonance imaging suggested an osteoid osteoma in the superior articular process of the seventh cervical vertebra. The...

Ten percent of all osteoid osteomas are located in the spine; they represent the most common cause of painful scoliosis in adolescents. The recommended treatment is surgical excision of the nidus. Nine patients with osteoid osteoma of the spine underwent surgical treatment between 1996 and 2002. Complete nidus removal was performed in all patients and the diagnosis was made by frozen sections i...
