Fine needle aspiration cytology of spindle cell variant of diffuse large B-cell lymphoma: a diagnostic dilemma

Primary non-Hodgkin lymphoma of the sphenoid sinus with visual disturbance: A report of two cases

Primary non-Hodgkin lymphoma (PNHL) of the sphenoid sinus is a rare neoplasm that poses a diagnostic challenge to clinicians. The proximity of the optical nerve and canal to the sphenoid sinus is accountable for the high incidence of visual disturbance in PNHL of the sphenoid sinus. In particular, patients whose radiologic diagnosis reveals bone destruction in the lateral wall involved with optical-nerve-canals or cavernous sinus present a high risk of rapidly developing unilateral blindness. The present study reports 2 rare cases of PNHL of the sphenoid sinus. Sudden sight loss may follow minimally invasive biopsy. In such cases, the measures that must be taken for the prevention of permanent sight loss are limited in the absence of the final pathologic diagnosis.

Primary lymphoma of bone presenting as spindle cell neoplasm of the vertebral body: a case report and review of the literature

Spindle cell variant of lymphoma is a very rare but known disease entity that can mimic a sarcoma. Diagnosis can be even more challenging if the only site of the disease is in the bone. We report a case of primary lymphoma of bone with spindle cell morphology which was successfully treated with a combination of surgery, chemotherapy, and radiotherapy.
