Sarcoidosis in Close Family Members and Susceptibility to High Grade B-Cell Lymphoma: A Case Report Study

The presented case is an 81- year-old woman who had experienced episodes of facial twitching without loss of consciousness and flu like symptoms for a few weeks prior to her admission. examinations were unremarkable except for left 3rd nerve and right 6th nerve palsy, right peripheral facial palsy and right -side hemiparesis. FH was positive for sarcoidosis. neuroimaging were in favor of PCNSL. Sarcoidosis and malignancy maybe etiologically related in at least 25% of cases. Coexis- tence of sarcoidosis and lymphoma have been reported previously. Our patient had two daughters with sarcoidosis and her chest CT scan showed multiple lymph nodes inmedias- tinum. Unfortunately, due to the location and the technical restriction, biopsy of mediasti- nal lymph nodes was not performedfor our patient and we could not differentiate whether it was reactive, paraneoplastic or granulomatous. We present this case as concurrence of lymphoma and sarcoidosis in a family, which could guide a new concern for the patient with granulomatous infiltrative disease for early diagnosis and familial screening.
