Primary T-cell lymphoblastic lymphoma in the middle ear

A Scoping Review of Otologic Manifestations of Hematologic Malignancies

OBJECTIVE

To examine the otologic and neurotologic symptoms, physical examination findings, and imaging features secondary to hematologic malignancies.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, databases, including PubMed, Scopus, and CINAHL, were searched for articles including patients with otologic manifestations of leukemia, lymphoma and multiple myeloma. Data collected included patient and study demographics, specific hematologic malignancy, timing and classification of otologic symptoms, physical examination findings, imaging features and methods of diagnosis. Pooled descriptive analysis was performed.

RESULTS

Two hundred seventy-two articles, of which 255 (93.8%) were case reports and 17 (6.2%) were case series, reporting on 553 patients were identified. Otologic manifestations were reported on 307 patients with leukemia, 204 patients with lymphoma and 42 patients with multiple myeloma. Hearing loss and unilateral facial palsy were the most common presenting symptoms for 111 reported subjects with leukemia (n = 46, 41.4%; n = 43, 38.7%) and 90 with lymphoma (n = 38, 42.2%; n = 39, 43.3%). Hearing loss and otalgia were the most common presenting symptoms for 21 subjects with multiple myeloma (n = 10, 47.6%; n = 6, 28.6%). Hearing loss and unilateral facial palsy were the most common otologic symptoms indicative of relapse in subjects with leukemia (n = 14, 43.8%) and lymphoma (n = 5, 50%).

CONCLUSION

Hearing loss, facial palsy, and otalgia might be the first indication of a new diagnosis or relapse of leukemia, lymphoma, or multiple myeloma. Clinicians should have a heightened level of suspicion of malignant etiologies of otologic symptoms in patients with current or medical histories of these malignancies.

Primary Presentation of Pediatric Hematopoietic Malignancy in the Temporal Bone: Case Report and Review of the Literature

Malignancy of hematopoietic origin comprises a large portion of all pediatric malignancies; however, it is uncommon for patients with this condition to present only with symptoms related to temporal bone involvement. Here, we report a case of Burkitt Lymphoma of the temporal bone in an 8-year-old patient who initially presented with symptoms of acute otitis media. Additionally, we review the current literature on pediatric hematopoietic malignancy with primary temporal bone involvement and discuss the clinical presentation, management, and outcomes of these rare cases.

Bilateral Facial Paralysis and Deafness in a Child Treated for Acute Lymphoblastic Leukemia

Involvement of the ear and temporal bone in acute leukemias are uncommon. We report a case of atypical mastoiditis with bilateral facial paralysis in a child diagnosed with Acute Lymphoblastic Leukemia (ALL). A 20-month-old male child was diagnosed with ALL and developed otorrhea unresponsive to antimicrobial treatment during the first week of chemotherapy followed by hearing loss, loss of balance, and bilateral facial paralysis. A CT scan of the mastoids showed cortical erosion of the temporal bone and presence of soft tissue contents filling the mastoid cells and external auditory canal bilaterally. Mastoidectomy was performed to collect material for analysis. Histopathologic examination of the material revealed an active chronic inflammatory process, with a moderate amount of plasma cells. Chemotherapy was reintroduced 3 weeks after the surgical procedure, and progressive improvement of otorrhea and imbalance was noted. Grade III House-Brackmann peripheral facial paralysis persisted on 6-month follow-up, and the patient is in rehabilitation program.

Unusual Tumors Obstructing the External Auditory Canal: Report of Two Cases

Primary tumors arising from the external auditory canal (EAC) are rare. We describe two cases of mass lesions within the EAC causing slowly progressive hearing loss without otorrhea or otalgia. Otoendoscopic examination demonstrated total obstruction of the EAC, and pure tone audiometry revealed conductive hearing loss. Based on the findings of the histopathologic examination, one patient was diagnosed with venous hemangioma that was treated using surgical resection, and the other patient was diagnosed with diffuse large B-cell lymphoma (DLBCL) that was treated using external-beam radiation therapy. Although primary tumors in the EAC are rare, both benign tumors such as venous hemangiomas and malignant lesions such as DLBCL should be considered as possible differential diagnoses of mass lesions in the EAC.

Extranodal non-B, non-T-cell lymphoma with bilateral tympanic bulla involvement in a cat

Case summary

A 9-year-old spayed female domestic shorthair cat with clinical signs suggestive of chronic recurrent otitis media and recent seizures was presented with multifocal nervous system disease, including bilateral central and/or peripheral vestibular, cerebellar and forebrain deficits. Prior to presentation, there was inadequate improvement after 6 weeks of treatment for bilateral middle ear effusion from which a highly susceptible Staphylococcus species was cultured. This was followed by the development of seizures. Results of a complete blood count and serum chemistry were unremarkable, and a previous feline leukemia virus/feline immunodeficiency virus ELISA was negative. The cat was hospitalized overnight and had multiple seizures. The following morning the cat’s mentation worsened, and the cat lost ventilatory drive after induction for anesthesia in preparation for MRI. A brain herniation event was suspected, and the cat was euthanized prior to further diagnostics. On post-mortem examination both tympanic bullae were filled with a soft, tan-colored material. Histologically, this material was composed of neoplastic lymphocytes. In addition, neoplastic lymphocytes were found in the leptomeninges, brain parenchyma, submandibular lymph nodes and pancreas. The neoplastic lymphocytes were negative for both B- and T-lymphocyte immunohistochemical markers and PCR for antigen receptor rearrangements failed to amplify target DNA, indicating non-B, non-T-cell lymphoma.

Relevance and novel information

To our knowledge, this is the first report of lymphoma with confirmed bilateral tympanic bulla involvement in the human and veterinary literature. Neoplasia should be considered in cases of middle-ear effusion that do not improve adequately with appropriate antimicrobial therapy.
