A case of retinoblastoma and Coats' disease in the same eye is presented. Coexisitence of the retinoblastoma and Coats' disease is very rarely seen, though the retinoblastoma or the Coats' disease are not uncommon diseases. After the enucleatIon under the clinical diagnosis of retinoblastoma, the careful histopathological study disclosed the unusual findings of a typical Coats' disease containing predominent telangiectasis adjacent to the undifferentiated retinoblastoma cell mass. Differentiation of Coats' disease to the so-called Coats' reaction associated with a certain retinal disorders is emphasized on the histological view point.

Objective: To report various intraocular conditions that mimic retinoblastoma. Methods: A review was conducted of eyeballs enucleated for suspected retinoblastoma between 2003 and 2007, and referred for histopathological confirmation. The slides of cases not histopathologically consistent with the diagnosis of retinoblastoma were reexamined. Clinical records and results of neuroimaging studies were reviewed retrospectively Results: Of the 197 eyeballs examined, 182 (92%) proved to be retinoblastoma on histological exam, while 15 (8%) from 13 patients were pseudoretinoblastomas. The age of patients ranged from 4 months to 9 years, with a mean of 35.5 months. The etiologies of the pseudoretinoblastomas were as follows: persistent primary hyperplastic vitreous (PHPV) in 5 eyeballs (33%); retinal dysplasia in 3 (20%); Coats’disease, phthisis bulbi, and vitreous hemorrhage with retinal detachment in 2 (13%) each; and granulomatous endophthalmitis in 1 (8%). Conclusion The 8% erroneous diagnosis was lower than the published rates of 10 to 20%. The common etiologies of pseudoretinoblastoma were similar to those reported.

Unilateral nevoid telangiectasia was first described by Blaschko in 1899. Since then there have been fewer than 100 reported cases. This rarely reported disorder consists of multiple telangiectasias primarily located unilaterally in the C3-T1 dermatomes. We describe unilateral nevoid telangiectasia in 13-year-old boy with association with increased estrogen level in puberty.

Telangiectasia macularis eruptiva perstans(TMEP) is an uncommon form of mastocytosis. This disorder is characterized by reddish-brown macules with telangiectases, usually involving the trunk. Due to the small number of mast cells, Darier's sign is usually absent. Histologic changes are very subtle, showing only a slight increase in mast cell numbers around capillaries and venules of the superficial plexus. We report two cases of TMEP. Their histologic alterations include dermal vascular dilatation and perivascular mast cell infiltration.

Hemorrhage due to capillary telangiectasia is rare. We report a case of capillary telangiectasia presenting with repeated cerebellar hemorrhage in a 38-year-old male. To our knowledge this is the first case of repeated cerebellar hemorrhage from the capillary telangiectasia. At the first operation, we removed hematoma only, but rebleeding occurred repeatedly in the same area. Finally, we evacuated the recurrent hematoma and vascular mass of capillary telangiectasia at the second operation under surgical microscope. Based on the findings of this case and a review of the literature, we conclude that capillary telangiectasia can be the cause of the massive repeated hemorrhage.

Rosacea is a chronic and recurrent inflammatory eruption of the flush areas of the face, particularly the nose, which is characterized by erythema, papules, pustules, and telangiectasia. Although the precise etiology remains as a mystery, various factors including genetic disposition, vascular dysfunction, solar elastotic degeneration, gastrointestinal disturbance, hormonal influences, increased humoral vasoactive mediators, and Demodex folliculorum infestation have been suspected of contributing to this condition. In recent study, it has been reported that a high density of Demodex folliculorum may have a pathogenic role in rosacea, especially in the development of inflammatory lesions. We report an unilateral rosacea-like chronic dermatitis of the left side of the face which was shown to harbor many Demodex folliculorum mites.
