Castleman's disease is an atypical lympho proliferative disorder comprising hyaline vascular elements, plasma cells, or a mixture of both, which can present in unicentric or multicentric fashion. Resection of unicentric lesions is typically curative, but multicentric disease, also characterized by constitutional symptoms and a poorer prognosis, often requires treatment with chemotherapy, radiation, steroids, or immune modulators. Castleman's disease is rarely diagnosed in the orbit. The authors present the clinical and histopathological findings of a 17-year-old who was found to have a focal lesion in her orbit. She was successfully treated with surgical resection and was free of disease recurrence or other sequelae at 10-months follow up.

Coined in 1961 by Hirsch and Helwig, the term chondroid syringoma refers to a rare mixed tumour of subcutaneous tissue. Histologically, these tumours are almost identical to pleomorphic adenomas, arising from salivary glands. With the obvious difference being the presence of sweat gland tissue (syringoma) within a matrix of cartilage (chondroid). These mixed tumours remain scarce throughout the world, with an incidence of less than 0.098%. The vast majority of cases are reported in middle-aged and older adults, where they typically present as painless swellings in the head and neck, which gradually grow in size.
