RESUMEN
This case report describes rare concomitant allergic fungal rhinosinusitis (AFRS) and chronic granulomatous invasive fungal sinusitis (CGIFS) in a 34-year-old woman with acute lymphoblastic leukemia and graft-versus-host disease (GVHD) post bone marrow transplantation. Initially presenting with rhinorrhea and nasal obstruction, the patient was diagnosed with AFRS in the right maxillary sinus, followed by a postoperative course of CGIFS in the left nasal cavity, showcasing the unique occurrence. She was not immunocompromised during diagnosis. CGIFS may have occurred because of surgery; however, voriconazole led to significant improvement. This case highlights noninvasive and invasive fungal infections in patients with chronic rhinosinusitis and a history of GVHD and underscores the complexity of diagnosing and managing such cases.
RESUMEN
We present two rare cases of parathyroid carcinomas associated with multiple brown tumours. Plain radiographs, computed tomography, and neck ultrasonography revealed the presence of bone and parathyroid tumours. Despite the use of 99m Tc-methoxy isobutyl isonitrile (99mTc-MIBI) or 18F-fluorodeoxyglucose-positron emission tomography (18F-FDG PET)/CT, it was difficult to differentiate bone metastases from brown tumours. Parathyroid carcinoma was confirmed by histopathological examination following parathyroidectomy, resulting in spontaneous bone lesion improvement. In patients with parathyroid carcinoma presenting with bone lesions suggestive of metastasis, understanding the potential for brown tumour accumulation through 99mTc-MIBI or 18F-FDG PET/CT is pivotal. With this understanding, it is possible to diagnose brown tumours with parathyroidectomy and follow up for improvement of bone lesion and avoid invasive biopsy or surgery.
RESUMEN
BACKGROUND: Transoral videolaryngoscopic surgery (TOVS) is widely used in Japan, and conventional two-dimensional (2D) endoscopic methods have been established. Three-dimensional (3D) endoscopic surgery offers superior distance perception because it provides stereoscopic views. Recently, we have developed 3D endoscopy for TOVS (3D TOVS). METHODS: This study included 46 patients with pharyngeal cancer who underwent 3D TOVS. The perioperative complications and survival curves were retrospectively analyzed. RESULTS: One patient with oropharyngeal cancer who underwent neck dissection and transoral resection simultaneously experienced postoperative hemorrhage of the neck. Another patient with oropharyngeal cancer underwent hemostasis for postoperative pharyngeal hemorrhage. There was one case of aspiration pneumonia. One patient developed cervical lymph node recurrence; however, there was no local recurrence or primary mortality. The 2-year overall survival, disease-specific survival, local control rates, locoregional control rate, and invasive disease-free survival were 90.9%, 100%, 100%, 97.4%, and 79.9%, respectively. CONCLUSIONS: Three-dimensional endoscopy can be safely applied to TOVS.

Patients with aortic arch malformations may present with recurrent inferior laryngeal nerve abnormalities that require special attention. Herein, we reported a case of thyroid surgery in a patient with a right aortic arch. The left inferior laryngeal nerve was presumed to be the right inferior laryngeal nerve by confirming the location of the aortic arch and subclavian artery, and the presence of the ductus arteriosus on preoperative computed tomography. Continuous intraoperative nerve monitoring is useful for safe surgery in patients with possible inferior laryngeal nerve abnormalities. Laryngoscope, 134:1986-1988, 2024.

BACKGROUND: Immune checkpoint inhibitors might cause immune-related adverse events that are still largely unknown. CASE PRESENTATION: An 80-year-old Asian female was diagnosed with cervical lymph node metastasis from lip cancer (cT1N0M0) and underwent right cervical neck dissection. Subsequently, she developed right cervical lymph node relapse and lung metastasis. The patient was deemed eligible for pembrolizumab owing to unresectable neck recurrence and pulmonary metastasis. The Combined Positive Score of the submandibular lymph nodes was 100. Pembrolizumab monotherapy was initiated, and complete remission was achieved. She developed diabetic ketoacidosis in the eighth month and was diagnosed with fulminant type 1 diabetes mellitus. Insulin induction was performed. The patient developed adrenal insufficiency after 10 months. These were immune-related adverse events, caused by pembrolizumab. The patient has remained in complete remission, and pembrolizumab therapy was continued. CONCLUSIONS: The study presents the first reported case of type 1 diabetes in a patient with head and neck squamous cell carcinoma treated with pembrolizumab monotherapy, in Japan. Efficient interdepartmental collaboration will promote the management of severe immune-related adverse events and improve the quality of life of patients.

OBJECTIVE: This study aimed to evaluate the clinical effectiveness of chemotherapy following immune checkpoint inhibitors (ICI). The association between inflammatory and nutritional factors and prognosis has also been investigated. METHODS: We retrospectively reviewed the medical records of recurrent or metastatic head and neck squamous cell carcinoma (RMHNSCC) patients who received chemotherapy following ICI therapy. The response rate and survival after chemotherapy, and nutritional and inflammatory factors, were examined. RESULTS: The ICI before chemotherapy was nivolumab in 36 patients (70.6%) and pembrolizumab in 15 patients (29.4%). The chemotherapy regimens consisted of PTX in 32 patients (62.7%), PTX + Cmab in 9 (17.6%), and S1 in 10 (19.6%). The median overall survival (OS) was 20 months (95% CI 12-25), the estimated 12-month OS rate was 63.3%, the median progression-free survival (PFS) was 5 months (CI 4-6), and the 12-month PFS estimate was 8.9%. Univariate analysis significantly correlated Neutrophil-to-Lymphocyte Ratio (NLR), platelet-to-lymphocyte ratio (PLR), controlling nutritional status score (CONUT), and prognostic nutrition index (PNI) with OS and PFS. Additionally, these factors were significantly correlated with OS and PFS in the log-rank tests. CONCLUSIONS: Chemotherapy following ICI is highly effective. There were no significant differences in the chemotherapy regimens. Inflammatory and nutritional factors may associate with patient prognosis after chemotherapy.
RESUMEN
Bezold's abscess is an extracranial complication of otitis media, in which a cervical abscess forms from the mastoid process through an ostial fistula, and is a rare condition in recent years. In this study, we experienced a X-linked agammaglobulinemia, which was discovered due to Bezold's abscess. Case: A 12-year-old boy suffering from recurrent right suppurative otitis media for three months was treated with tympanostomy and oral antibacterial therapy at a local otorhinolaryngology clinic. The patient visited the clinic due to a recurrence of symptoms. CT showed bony defects in the cortical bone and mastoid process of the lateral side of the right mastoid cell. The patient was referred to our hospital, admitted the same day and underwent emergency surgery. Intraoperative findings led to the diagnosis of acute mastoiditis and Bezold's abscess c aused b y mastoiditis spreading to the s ternocleidomastoid muscle. After drainage and administration of ABPC/SBT, the abscess disappeared, and the patient's general condition improved. Subsequently, a blood typing test performed on admission suggested the influence of low immunoglobulin levels. A close examination by the pediatric department led to a diagnosis of X-linked agammaglobulinemia. As a result, the patient receives regular immunoglobulin therapy and has been free of infection, including Bezold's abscess. CONCLUSIONS: In the case of recurrent otitis media and rare infections, congenital immune abnormalities should be considered.

Background: Transoral salvage surgery has the potential to preserve a patient's quality of life. Therefore, we investigated the outcomes, safety, and risk factors for postoperative complications of salvage transoral videolaryngoscopic surgery (TOVS) for recurrent hypopharyngeal carcinoma after radiotherapy (RT) or chemoradiotherapy (CRT). Methods: This retrospective analysis enrolled patients with hypopharyngeal cancer who had a history of RT or CRT and underwent TOVS from January 2008 to June 2021. The factors related to postoperative complications, postoperative swallowing functions and survival rates were analyzed. Results: Seven patients (36.8%) of the 19 patients developed complications. Severe dysphagia was the primary complication, and post-cricoid resection was a complication risk factor. The FOSS score was significantly lower in the salvage treatment group. The survival rates were: 3-year overall survival: 94.4%; disease-specific survival: 94.4%; 5-year overall survival: 62.3%; and disease-specific survival: 86.6%. Conclusions: Salvage TOVS for hypopharyngeal cancer was feasible, and oncologically and functionally reasonable. Level of Evidence: 2b.
RESUMEN
This study aimed to determine the prognostic value of inflammatory and nutritional biomarkers of immune checkpoint inhibitor (ICI) therapy for recurrent or metastatic squamous cell carcinoma of the head and neck (RMHNSCC) and to identify the most useful factor for prognosis assessment. We retrospectively reviewed the medical records of patients with RMHNSCC who received ICI therapy. The response rate for ICI therapy and the relationship between inflammatory and nutritional biomarkers and overall survival were examined. The included biomarkers did not correlate with an objective response rate but were associated with a disease control rate. Univariate analysis showed significant correlations between the serum albumin level, C-reactive protein level, platelet to lymphocyte ratio, neutrophil to lymphocyte ratio, lymphocyte to monocyte ratio (LMR), systemic immune-inflammation index, and controlling the nutritional status score and overall survival; multivariate analysis showed that LMR was significantly correlated with overall survival. LMR was the most important biomarker according to the machine learning model. This study suggests that LMR may be the most useful biomarker for predicting the prognosis of ICI treatment for RMHNSCC.
RESUMEN
Magnetic resonance imaging (MRI) is a more useful diagnostic modality for detecting paranasal tumors compared with computed tomography (CT). We encountered a case of malignant lymphoma of the maxillary sinus. Although CT findings suggested malignancy, MRI findings indicated an inflammatory disease. The patient was a 51-year-old man with a chief complaint of right maxillary toothache. Edema in the right middle meatus and bloody rhinorrhea were observed. CT revealed r ight maxillary s inus shadow with partial bone loss, suggesting malignancy. However, MRI performed two weeks later showed an internal homogeneous lesion with neither contrast effect, nor invasion outside the maxillary sinus. The patient also had no fever, weight loss, or night sweats. Additionally, no palpable cervical lymphadenopathy was observed. Endoscopic sinus surgery was performed to confirm the diagnosis. Upon opening the maxillary sinus, highly viscous retention and a large amount of yellowish-white debris were observed. Allergic fungal rhinosinusitis was suspected. However, histopathological analysis of the debris established a diagnosis of malignant lymphoma. The debris exhibited pathological findings of necrosis. The patient remained in remission after undergoing radiochemotherapy. Malignant lymphomas of the paranasal sinuses, which have a minimal tendency for invasion but with considerable predominance of necrosis, may be diagnosed as an inflammatory disease, based on MRI findings. In cases in which a thorough physical examination could not rule out malignant lymphomas, an endoscopic biopsy should be immediately considered.

BACKGROUND/AIM: In December 2019, pembrolizumab was approved in Japan for the treatment of head and neck cancer with recurrence or distant metastasis, making it a new option for first-line treatment. However, there are still many unanswered questions about Overall survival (OS), Progression free survival (PFS), adverse events including immune-related adverse events (irAEs), and biomarkers. AIMS/OBJECTIVES: The aim of this study was to retrospectively review first-line treatment of head and neck cancer with recurrence or distant metastasis treated with pembrolizumab and to determine whether Combined positive score (CPS) is still useful as a biomarker in the clinical practice. MATERIAL AND METHODS: We retrospectively reviewed clinical records of 20 patients who received pembrolizumab as first-line treatment for head and neck cancer with recurrence or distant metastasis between December 2019 and March 2021. RESULTS: Age ranged from 45 to 83 years (median 66 years), 17 male patients and 3 female patients. The response rate was 40%, and the disease control rate was 60%. OS and PFS in patients with CPS < 1 were significantly worse than those with CPS ≤ 1 (CPS-positive patients). The OS and PFS of patients with CPS < 1 were s ignificantly worse than those of p atients with 1 < = CPS (CPS-positive p atients), and there was no significant difference between the group with CPS between 1 and 20 and the group with CPS over 20. And we experiences several CR cases with high CPS. CONCLUSION: CPS is a useful biomarker for pembrolizumab. SIGNIFICANCE: There are no reported cases of CR after two courses of pembrolizumab in head and neck cancer. There are no reports of pembrolizumab in patients with head and neck cancer in Japan.
