Osteofibrous dysplasia is a kind of innocent bone tumor derived from fibrous tissue. Its pathogens has not been identified, it rarely affects the temporal bone, its clinical manifestations mainly is hearing loss. Imageological examination, for example, CT and MRI, is valuable for the diagnosis of this disease,the histopathological evidence is absolutely necessary to make definite diagnosis. Surgery is an effective method to treat the fibrous dysplasia of temporal bone.

Giant cell tumor of bone (GCTB) seldom occurs in the head or face. This article reported a case that GCTB occurred simultaneously in the temporal bone and mandibular condyle, and analyzed their clinical and pathological features.

Cholesterol granulomas are inflammatory deposits commonly found in the mastoid antrum and air cells of temporal bone. They rarely occur in the nose. Here, we report an extremely rare case of cholesterol granuloma in the nasal septum, and include a short literature review. The clinical characteristics, pathology, and surgical treatment are also discussed.

The clinical data of one patient with left ear temporal eccrine spiradenoma in our hospital were retrospectively analyzed. Eccrine adenoma, also known as the eccrine spiradenoma (eccrine spiradenoma, ES), a benign tumor derived from sweat glands, are typically single spherical or oval slow increases substantive or cystic nodules block, diameter of 1-2 cm, skin color or light blue. It's a rare case for young women, shorter onset time, more huge tumor, skin ulceration and exudate. This disease is a benign tumor, surgical resection could lead to a good result. It should be followed up after surgery.

Chondroblastoma is a rare benign bone tumor. It commonly affects the epiphysis of long bones during the second and third decades of life. Chondroblastoma of the temporal bone is extremely rare. We reviewed five cases of chondroblastoma arising in the temporal bone. Four cases were female and one was male. The ages ranged from 41 to 60 years (mean, 53.6 years). All cases involved the temporal bone. Three involved the left side and two the right. Chief complaints were long-standing localized pain and hearing difficulty. A sharply demarcated lobulated mass was the main radiological finding. Microscopic findings were those of chondroblastoma of usual locations. Two cases showed aneurysmal bone cyst-like areas. Immunohistochemical studies for CD34, CD99, S-100 protein and cytokeratin were performed. Tumor cells were diffusely positive for S-100 protein in three cases and weakly positive for cytokeratin in one case. CD34 and CD99 were negative in all cases. In summary, chondroblastoma of the temporal bone is rare and occurs in older age group than reported cases of chondroblastoma of the usual location in the literature.

A rare case of telangiectatic osteosarcoma of the sphenoid bone was reported. The patient was a 27-year-old male and had suffered from left eye protrusion and diplopia for three months. Radiologically, a lobulated osteolytic lesion was located between sphenoid and left temporal bone. Pathologically, the tumor had multiloculated blood filled cystic vascular spaces and osteoid formation by malignant spindle osteoblast cells. The differential diagnosis of this rare entity from aneurysmal bone cyst was important radiologically and pathologically. This case is the second case of telangietatic osteosarcoma of the sphenoid bone followed by a case of Whitehead RE and Melhem ER in 1998.
