Small clonal B-cell population in the bone marrow as a possible tool in the diagnosis of occult primary parotid lymphoma
Case Description: An 82-years old Hispanic woman with a past medical history significant for pulmonary thromboembolism on oral anticoagulation, rheumatoid arthritis, and hypertension developed a new onset thrombocytopenia. Clinical Findings: Small clonal B-cells populations (SCBP) also known as mono...

Summary: | Case Description: An 82-years old Hispanic woman with a past medical
history significant for pulmonary thromboembolism on oral
anticoagulation, rheumatoid arthritis, and hypertension developed a new
onset thrombocytopenia. Clinical Findings: Small clonal B-cells
populations (SCBP) also known as monoclonal B-cell lymphocytosis was
found as part of the workup for an idiopathic thrombocytopenia and lead
ultimately to the diagnosis of parotid primary follicular lymphoma
coexisting with Warthin tumor involving the bone marrow in a small
extent and oncocytic papilloma located in the maxillary sinus.
Treatment and Outcome: Patient was treated with Rituximab monotherapy
with improvement on her platelet count. Clinical relevance: Although it
is unclear the role of this clonal cells, they may work as a possible
diagnostic tool for occult lymphomas. Further prospective studies are
needed to confirm this possible association.
Descripción de caso: Mujer hispana de 82 años con una
historia médica significativa de tromboembolismo pulmonar en
anticoagulación, artritis reumatoide e hipertensión, la cual
desarrolló recientemente una trombocitopenia Hallazgos
clínicos: Una pequeña población de células B
monoclonales también conocida como linfocitosis monoclonal de
células B fue encontrado dentro del estudio de una trombocitopenia
idiopática que conllevó al diagnóstico de un linfoma
folicular primario de parótida coexistiendo con un tumor de
Warthin y un papiloma oncocítico localizado en el seno maxilar.
Tratamiento y resultado: La paciente fue tratada con monoterapia de
Rituximab con una mejoría en su conteo de plaquetas. Relevancia
clínica: Aunque el rol de las pequeñas poblaciones B
monoclonales no está completamente dilucidado, podrían tener
una aplicación como herramienta diagnóstica. Futuros estudios
prospectivos son necesarios para confirmar esta posible
asociación. |
