Intraorbital pseudotumors are inflammatory lesions of the orbit of unknown etiology, which initially mimic an orbital neoplasm. The authors report a case of intraorbital pseudotumor presenting with painful exophthalmos. A 45-year-old male patient had a two-week history of acute progressive exophthalmos and diplopia. Right orbit was explored through transcranial route and the mass was biopsied, which revealed dense inflammatory cells and fibrosis. He subsequently underwent corticosteroid therapy and symptoms improved gradually. The literatures were reviewed.

Frequent causes of exophthalmos are orbital inflammations, vascular disorders, various orbital neoplasms, metabolic diseases, and developmental anomalies. But subperiosteal hematoma is a rare cause of exophthalmos. We experienced three cases of exophthalmos caused by the subperiosteal hematoma and managed successfully by needle aspiration and conservative treatment.

A 61-year-old man with no history of malignancy presented with a rapidly expanding left periorbital mass, first noticed one month prior to presentation. The mass was firm, and a pus-like discharge drained spontaneously from the center of the lesion. A biopsy was performed, and histopathology confirmed squamous cell carcinoma. Systemic evaluation revealed that the patient had a primary esophageal squamous cell carcinoma with multiple metastases. The prognosis of orbital metastasis is generally poor, and this patient expired after one month of conservative treatment.

A subconjunctival orbital fat prolapse is frequently confused with a dermolipoma clinically. These two entities have similar clinical appearances, but are clearly distinct. The clinical features, differential diagnosis, and treatment modalities of subconjunctival orbital fat prolapse and dermolipoma are discussed.

A case of congenital orbital teratoma with marked unilateral proptosis was noted at birth, Patients with congenital orbital teratoma had a uniform clinical picture and were very similar in their morphological pattern, often polycystic and with varied amounts of solid tissue. Six months after birth, the orbital tissues were totally extirpated. Histological examination revealed components from all three germinal layers and no sign of malignancy. Within the first year, the condition of the patient has been satisfactory.
