ABSTRACT

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.

ABSTRACT

Acinetobacter skin and soft tissue infection outside of the traumatic wound setting are rare occurrences. The majority of cases occur in the presence of significant comorbilities and by Acinetobacter baumanii. Herein a case is reported of community-onset, health-care-associated, non-traumatic cellulitis caused by Acinetobacter, species junii-johnsonii with bacteremia. This is the first reported case of Acinetobacter junii-johnsonii skin and soft tissue infection. Hemorrhagic bullae might be one of the clinical features of Acinetobacter cellulitis.


La infección de piel y tejidos blandos por Acinetobacter no relacionada con trauma es una presentación inusual. La mayoría de los casos descritos presentan enfermedades concomitantes y son causados por Acinetobacter baumanii. Se describe un caso de celulitis no traumática por A. junii-johnsonii con bacteriemia, de inicio en la comunidad y asociado con el tratamiento médico. De acuerdo con nuestro conocimiento, éste sería el primer caso reportado de infección de tejidos blandos y piel por A. junii-johnsonii. La vesícula hemorrágica podría ser una característica clínica de celulitis por Acinetobacter.
