a Tumor mass consisting of coalescent hard lymph nodes that have infiltrated adjacent tissues and skin, posteriorly located on the left side of the neck. b Myosis, slight upper eyelid ptosis, and enophthalmos characterizing Horner's syndrome in the left eye. c The phenylephrine 1% test shows bilateral mydriasis which is more pronounced in the affected left pupil than in the non-affected right pupil. The test results locate the lesion in the third-order neuron level (post-ganglionic).

It consisted of a coalescent group of hard lymph nodes that infiltrated adjacent tissues and skin, posteriorly located on the left side of the neck (fig. 1a). Simultaneously she presented ipsilateral miosis, slight superior eyelid ptosis, and enophthalmos typical for Horner's syndrome (fig. 1b). The ocular phenylephrine 1%-test revealed minimal dilatation in the normal right pupil and pronounced dilatation in the left affected pupil (fig. 1c).
