Hello XXXXX,
You are suffering from a condition known as Actinic keratosis.
This is a condition in which the skin cells form hard crusty lumps, often with a hard white covering , making the lump look like a fingernail or a tooth.
This condition occurs frequently in areas which are exposed to the sun and also in individuals in whom the immune system is suppressed. In your case, your immune system has been suppressed by Rituxan. Since Rheumatoid arthritis is an autoimmune disease, medicines like Rituxan, which is an immuno-supppressant are often prescribed.
The risks with actinic keratosis is that it is a premalignant condition of skin cancer.
Please consult a dermatologist for a biopsy for an accurate diagnosis.
If it is actinic keratosis, you may need to consult your doctor for a review of Rituxan.
