Have you heard of lymphoma of one of the eye muscles? My husband had a biopsy yesterday. The superior rectus muscle is 4 times normal size causing his eye to protrude and tear. First symptom was a drooping eyelid about 1 year ago. No pain.

Lymphoma can develop virtually anywhere in the body because lymphocytes go virtually everywhere in the body, and in the case of this area of the body, involvement of the extraocular muscles is possible, although pretty rare. There are several subtypes of non-Hodgkin's that are considered lymphomas of the eye, but the muscle you refer to is part of the orbit, and those fall under the category of "ocular adnexal lymphomas" or OAL. Generally speaking, these are further classified as extranodal marginal zone lymphomas of mucosa-associated lymphoid tissue (i.e. MALT lymphomas). They are almost always of B-cell origin, which is much better news than if they were of T-cell origin. Drooping eyelid- and excessive tear production- are indeed two symptoms, but they are non-specific and can indicate lots of things. So to answer your question yes, there are cases of people developing lymphoma of the eye involving the extraocular muscle. But I would imagine that lymphoma is not the only possibility.

If you have a follow up appointment scheduled with your doctor, it's possible you'll learn the pathology results then. But it's likely they'll be ready sooner than that. You can always call your doc, find out what lab is doing the pathology, and learn when the results will be ready, and learn sooner than you otherwise might. If the not-knowing is too much for you, that is.

You might find this PDF from MD Anderson informative, it's called Advances in the Treatment of Eye Cancer and mentions quite a few different potential cancers of the eye and how they are treated.
