Non-Hodgkin's lymphoma of the frontal sinus presenting as osteomyelitis

Sinonasal Malignancies Involving the Frontal Sinus: A Mono-Institutional Experience of 84 Cases and Systematic Literature Review

Frontal sinus involvement by malignant tumors is a rare finding. Therefore, a systematic literature review along with a personal case series may contribute to defining more accurately the epidemiology, treatment options, and outcomes of these neoplasms. This is a retrospective review of patients affected by frontal sinus malignancies surgically treated in a tertiary-care referral center over a period of 20 years. Moreover, a systematic literature review of studies describing frontal sinus cancers from 2000 to date was performed according to PRISMA guidelines in order to analyze current evidence about the treatment and outcomes of such a rare disease. Our retrospective review was basedon 84 cases, treated with an exclusive endoscopic approach in 43 cases (51.2%), endoscopic approach with frontal osteoplastic flap in 6 cases (7.1%), and transfacial or transcranial approaches in 35 cases (41.7%). The five-year overall, disease-specific, disease-free, and recurrence-free survivals were 54.6%, 62.6%, 33.1%, and 59.1%, respectively. Age, dural involvement, type of surgical resection, and surgical margin status were significantly associated with the survival endpoints. In conclusion, the involvement of the frontal sinus is associated with a poor prognosis. Multidisciplinary management, including specific histology-driven treatments, represents the gold standard for improving outcomes and minimizing morbidity.

Diffuse large B cell lymphoma originating from the maxillary sinus with skin metastases: A case report and review of literature

BACKGROUND

Diffuse large B-cell lymphoma (DLBCL) is the most common type of malignant lymphoma (ML), accounting for 30%-40% of cases of non-Hodgkin’s lymphoma (NHL) in adults. Primary paranasal sinus lymphoma is a rare presentation of extranodal NHL that accounts for only 0.17% of all lymphomas. ML from the maxillary sinus (MS) is a particularly rare presentation, and is thus often difficult to diagnose. We have reported the first known case of DLBCL originating from the MS with rapidly occurrent multiple skin metastasis.

CASE SUMMARY

An 81-year-old Japanese man visited our hospital due to continuous pain for 12 d in the left maxillary nerve area. His medical history included splenectomy due to a traffic injury, an old right cerebral infarction from when he was 74-years-old, hypertension, and type 2 diabetes mellitus. A plain head computed tomography (CT) scan revealed a 3 cm × 3.1 cm × 3 cm sized left MS. On day 25, left diplopia and ptosis occurred, and a follow-up CT on day 31 revealed the growth of the left MS mass. Based on an MS biopsy on day 50, we established a definitive diagnosis of DLBCL, non-germinal center B-cell-like originating from the left MS. The patient was admitted on day 62 due to rapid deterioration of his condition, and a plain CT scan revealed the further growth of the left MS mass, as well as multiple systemic metastasis, including of the skin. A skin biopsy on day 70 was found to be the same as that of the left MS mass. We notified the patient and his family of the disease, and they opted for palliative care, considering on his condition and age. The patient died on day 80.

CONCLUSION

This case suggests the need for careful, detailed examination, and for careful follow-up, when encountering patients presenting with a mass.

Pediatric Diffuse Large B-Cell Lymphoma of the Frontal Sinus: A Case Report

An 11-year-old male presented with right proptosis, bulbar conjunctivitis, and diplopia. Computerized tomography (CT) and magnetic resonance imaging revealed an enhancing mass involving the superio-medial orbit, ethmoids, frontal sinus, and anterior cranial fossa with skull base destruction. Diffuse large B-cell lymphoma was diagnosed via CT-guided biopsy. As a component of multidisciplinary care, the patient underwent frontal sinus cranialization, with orbital and skull base reconstruction. Trauma reconstructive principles guided recreation of orbital, frontal sinus, and anterior skull base anatomy. This rare primary location is undescribed in the pediatric literature.

Frontal Sinus Malignancies: A Population-Based Analysis of Incidence and Survival

OBJECTIVE

Primary neoplasms originating in the frontal sinus are rare. As such, existing literature describing frontal sinus malignancies (a subset of frontal sinus neoplasms) is limited. Prognostic implications of these malignancies are difficult to determine. This study seeks to analyze trends in epidemiology, clinicopathology, incidence, and survival for these rare malignancies.

STUDY DESIGN

Retrospective database analysis.

METHODS

The SEER 18 database (Surveillance, Epidemiology, and End Results; 1973-2012) was searched for frontal sinus malignancies from 1973 to 2012 and analyzed for demographic and clinicopathologic trends. The Kaplan-Meier model was utilized for survival analysis.

RESULTS

A total of 171 cases of frontal sinus malignancies were identified. Incidence was 0.011 per 100,000 individuals. The mean age at diagnosis was 61.1 years, with males constituting the majority of cases (61.4%). 80.1% of patients were white, 9.4% Asian, and 8.2% black. The average tumor size was 3.8 cm. The most common histology encountered was squamous cell carcinoma (39.8%). Overall 5-year disease-specific survival was 44.2%. Five-year disease-specific survival was highest for mature B-cell non-Hodgkin's lymphomas (72.3%) and lowest for adenocarcinomas (15.4%).

CONCLUSIONS

Malignant tumors of the frontal sinus are rare and are more common in males. Squamous cell carcinoma is the most common entity encountered. Of the 4 most common histologies, survival is best for mature B-cell non-Hodgkin's lymphomas and worst for adenocarcinomas.

Diffuse Large B-Cell Lymphoma of the Frontal Sinus Presenting as a Pott Puffy Tumor: Case Report

Objective Sinonasal non-Hodgkin lymphoma (NHL) is a very rare condition. NHL located specifically in the frontal sinus is even rarer with only 14 cases in the literature reported to date. A unique case of diffuse large B-cell lymphoma of the frontal sinus that presented first and was treated as suspected Pott puffy tumor is presented along with a review of the literature. Case Report A 69-year-old white man with a history of sinusitis and two recent endoscopic sinus surgeries presented with enlargement of his right forehead. Computed tomography and magnetic resonance images revealed a dense opacification of the frontal sinus bilaterally, thickening and enhancement of the dura mater behind the right frontal sinus, and local osteomyelitis-like lytic bone changes. A bifrontal craniotomy was performed. Radical exoneration of the frontal sinus, copious antibiotic-impregnated irrigation after culture swabs, and resection of presumed granulation tissue was performed. Culture swabs remained negative, but histopathology revealed diffuse large B-cell lymphoma. Subsequent chemotherapy was administered. Conclusion Sinonasal NHL is very rare but can occur in the frontal sinus and may present as a suspected Pott puffy tumor. A high clinical suspicion is necessary for early diagnosis and treatment.

Primary diffuse large B-cell lymphoma associated with chronic osteomyelitis of the knee

Diffuse large B-cell lymphoma (DLBCL) associated with chronic inflammation is a recently adopted category of DLBCL, which describes an aggressive B-cell lymphoma raised in the setting of non-immune chronic inflammation. Primary presentation of this subtype of DLBCL in bone is extremely rare. Here, we present the case of a 27 year old woman with DLBCL of the right distal femur, identified after a three-year history of chronic osteomyelitis. In this report, we describe the clinical and histopathologic features of this unusual presentation of DLBCL and discuss aspects relevant to diagnosis and treatment of this entity.

Frontal sinus lymphoma presenting as progressive multiple cranial nerve palsy

Primary frontal sinus lymphoma is a very uncommon disease. In all the previously reported cases, the presenting symptoms have been due to the tumor mass effect. We present an unusual case report of an immunocompetent patient who presented with facial palsy, and then progressively developed other cranial nerve palsies over several months. He was later diagnosed with diffuse large B cell lymphoma originating from the frontal sinus. The patient underwent chemotherapy, but eventually had to receive autologous peripheral blood stem cell transplantation. He is currently disease-free. The clinical course, diagnostic workup, and therapeutic outcome are described.
