Abnormal cytogenetics in orbital lipoma.

Orbital lipoma is a rare entity with only a small number of cases previously described. The authors describe a case of orbital lipoma in a 56-year-old man, which was treated with surgical excision. Cytogenetic analysis of the lesion demonstrated abnormalities of chromosome 12, consistent with chromosomal abnormalities in lipomas found elsewhere in the body.

Eyelid contracture may indicate recurrent basal cell carcinoma, even after Mohs' micrographic surgery.

Mohs' micrographic surgery (MMS) is an effective means of margin control in the management of periocular basal cell carcinomas (BCC). We describe three cases of recurrent BCC that presented with progressive eyelid contracture after MMS. They illustrate high-risk factors for recurrence, namely large tumor size, medial canthal location, previous treatment, and aggressive histological features.

Recurrent orbital cholesterol granuloma.

Cholesterol granuloma is an uncommon entity, occurring typically in the supero-temporal orbit. Recurrence has only rarely been reported. We describe a case of recurrent cholesterol granuloma in a 48-year-old-man to illustrate the clinical features of the condition, and to highlight the importance of complete resection to prevent recurrence.
