BACKGROUND: Pantoea agglomerans is a gram negative, aerobic/facultative anaerobic, rod shaped bacilli commonly isolated from plants, soil, food and faeces.(1) It is a rare cause of opportunistic infections in humans acquired mainly via two major routes being, wound infection or hospital acquired.
METHODS: Here, we encountered a landmark, first of its kind, head and neck manifestation of a cervical soft tissue abscess with Pantoea agglomerans being the miscreant. The patient presented with complaints of a left sided neck swelling, which was radiologically suggestive of a cold abscess, however clinical suscpicion encouraged us to perform an incision and drainage, culture of which revealed this notorious phytogenic bacterium.
CONCLUSIONS: Commonly encountered Pantoea infected cases documented in literature have shown a clinical picture of endophthalmitis, acute unilateral dacryocystitis, periostitis, endocarditis, osteomyelitis and a tumour like muscle cyst of the thigh with many of them eventually leading to septicemia while a few also resolved with targeted antibiotics.(2) Remarkably, no ENT or head and neck presentations have been reported in literature till date. History of trauma by brushing against a mango tree was confirmed retrospectively, which was found to be the missing piece of the puzzle.

Cutaneous metastasis from head and neck cancers is rare, typically presenting as single or multiple nodules. This report presents a truly unique and intriguing case of squamous carcinoma of the tongue, in which the patient developed numerous metastatic nodules in the face and neck, a phenomenon rarely seen in clinical practice. The patient, a known case of carcinoma tongue, was treated radically with concurrent chemoradiation. He presented with small cutaneous lesions in his neck and upper chest, which were confirmed as cutaneous malignancies. Despite receiving one cycle of palliative chemotherapy, the management of this case posed significant and complex challenges, requiring a deep understanding of the nature of the spread and metastatic pathway for choosing the appropriate management.

BACKGROUND: Changes in the fatty infiltration and/or muscle volume of neck muscles can alter cervical spine alignment and cranial load distribution, which may cause pain in the orofacial region.
OBJECTIVE: The aim of the study was to examine the muscle volume and fatty infiltration of neck muscles in patients with temporomandibular disorders (TMD).
METHODS: This case-control study included 18 patients with TMD and 18 ageand sex-matched controls. The muscle volume and fatty infiltration of the neck muscles of the participants were measured using magnetic resonance imaging (MRI) and ITK-SNAP software. The 3D models of the sternocleidomastoid (SCM), splenius capitis (SPLC), semispinalis cervicis (SC)-semispinalis capitis (SCP), and multifidus (M) muscles within the C3-C7 range were created using ITK-SNAP, a semi-automatic segmentation software. The models were used to determine the volumes and fatty infiltration levels. The Neck Disability Index (NDI) was used to assess neck pain-related disability. The severity of TMD was determined using the Fonseca Anamnestic Index (FAI), while jaw-related disability was measured with the Jaw Functional Limitation Scale-20 (JFLS-20). Pain levels were recorded at rest and during chewing using the numeric rating scale (NRS).
RESULTS: There were no statistically significant differences in total muscle volume, fatty infiltration volume and fatty infiltration percentage of the SCM, SPLC, SCP, SC, and M muscles between the 2 groups (p > 0.05). The patient group had higher NDI scores compared to the controls (p < 0.001). The NDI scores correlated positively with the JFLS-20 (r = 0.831, p < 0.001), FAI (r = 0.815, p < 0.001) and NRS scores at rest (r = 0.753, p < 0.001) and during chewing (r = 0.686, p < 0.001).
CONCLUSIONS: The present study did not identify any significant differences in the neck muscle volume or fatty infiltration between the TMD patients and controls. However, the severity of neck disability was found to correlate with jaw function, pain and TMD levels.

UNASSIGNED: Neck lumps are a common presentation to primary care services. The aetiology of posterior neck lumps is poorly explored in the literature, and therefore remain a concern to patients and clinicians. This often results in an urgent referral for ultrasound assessment. The authors of this study sought to evaluate the aetiology of posterior neck lumps from a radiological perspective, to assess whether ultrasound can be used as a useful adjunct, rather than a first-line urgent investigation.
UNASSIGNED: A retrospective case series was carried out, examining all primary care referred ultrasound studies for assessment of posterior neck lumps, performed at a single institution in Essex, United Kingdom, over a period of over 10 years dating between 2nd February 2012 to 8th November 2022. Data was collected on: patient age at the time of study, patient sex, whether the lump was single or multiple as palpated and documented by the primary care physician, size of the lump to the nearest 0.5 cm as documented on ultrasound using the longest dimension, sonographic diagnosis and any follow up imaging (not limited to ultrasound).
UNASSIGNED: A total of 623 neck ultrasounds were performed on 615 adults. Of the overall radiological diagnoses made from the 623 scans, 555 (89.09%) scans were benign, 63 (10.11%) scans had no lump found on sonography, and 3 (0.48%) scans showed malignancy. In the remaining 2 (0.32%) scans, the lump was deemed indeterminate. The most common aetiologies for benign lumps were due to: normal lymph nodes (n = 263; 42.21%), lipomas (n = 152; 24.39%), and benign dermal cysts (n = 105; 16.85%). All 3 malignant cases had co-existing anterior and posterior neck lumps.
UNASSIGNED: Given that the overwhelming majority of posterior neck lumps in our study had benign findings, we propose that patients with solitary or even multiple posterior neck lumps alone, regardless of size can either be investigated routinely or can be reassured depending on other clinical examination characteristics. Patients who have the presence of co-existing anterior and posterior neck palpable neck lumps justifies urgent or 2-week wait radiological investigation.

The thymus derives from the third branchial pouch, which migrates to the mediastinum through the central region of the neck. During the migration, particles split off and develop separately. The prevalence of ectopic thymus is 20-40%. The purpose of this retrospective case series study was to investigate the prevalence of embryological tissue remnants in the central region, in patients treated for thyroid lesions. Between January 1 2018 and September 1 2020, 84 patients who underwent central neck dissection were selected. Clinicopathological data as age, gender, histopathological result and TNM stage were analyzed. Ectopic tissue in the central neck region was discovered in 28 cases. The prevalence of ectopic lesions showed increase in Stage I thyroid carcinomas. There was no significant correlation with patients\' age, gender, or with the stage. We emphasize the clinicopathological role of ectopic tissues, which can occur in the central region of the neck.

BACKGROUND: Manifestation of cystic hygroma in adulthood is very rare. The rarity of cystic hygroma in adults has caused problems in its diagnosis and management and few studies have reported cystic hygroma in adults.
METHODS: In this study, we reported a rare case with cervical cystic hygroma in adults. We report a 20-year-old Iranian male (Iranian ethnicity) with a diagnosis of right-side neck cystic hygroma and discuss the presentation, diagnosis, and clinical, radiological, and operative aspects of it.
CONCLUSIONS: Cystic hygromas are a rare occurrence in adults. They are typically asymptomatic, rarely complicated, and can be mistaken for a cystic neck mass. This study showed that in our case, surgical resection may be a safe and effective treatment for cystic hygroma, with minimal risk of complications during the procedure.

Postural sway has not been investigated before or after a neck exercise intervention in individuals with chronic whiplash-associated disorders (WAD). The aim of the study was to investigate postural sway in individuals with chronic WAD grades 2 and 3: (a) compared with healthy matched controls at baseline; (b) after three months of neck-specific exercise and (c) to investigate the correlation between postural sway with self-reported dizziness during motion and balance problems/unsteadiness. This is a longitudinal prospective experimental case-control intervention study. Individuals with WAD (n = 30) and age- and gender-matched healthy volunteers (n = 30) participated. Postural sway was assessed using an iPhone application. Measurements were carried out at baseline, and for those with WAD a second measurement was performed at the three-month follow-up when neck-specific exercise intervention ended. The WAD group performed significantly worse than the healthy group in both pathway and ellipse area double stance eyes closed at baseline (main outcome), but not at the three-month follow-up. The WAD group significantly improved after rehabilitation in both pathway double stance eyes closed and pathway single stance eyes open. The correlation between postural sway and self-rated dizziness during motion and balance problems was low to moderate. One may conclude that postural sway was improved after a neck-specific exercise programme. The study results strengthen earlier findings that individuals with WAD have worse balance outcome when they have to rely on neck proprioception (eyes closed). The study results may be important for the development of improved rehabilitation methods for WAD.

BACKGROUND: Acute epiglottitis is not uncommon and it can cause high mortality due to airway obstruction. Acute epiglottitis complicated with cervical necrotizing fasciitis has rarely been reported, and it is also a life-threatening disease with a fatality rate of 7% to 50%.
METHODS: A 64-year-old woman presented to our hospital with chief complaints of sore throat and cervical swelling, long with foreign body sensation and hoarseness. Endoscopic laryngoscopy showed erythematous and swollen epiglottis with purulent secretions on the surface. Computed tomography (CT) scan showed swollen epiglottis and swelling of the neck with air- and fluid-containing necrotizing tissue.
METHODS: The diagnosis was acute epiglottitis and abscess complicated with cervical necrotizing fasciitis.
METHODS: With the patient in awake condition, airway access was established by performing intubation with adjunctive use of gum elastic bougie, followed by surgical debridement under general anesthesia; a flap was used for skin coverage and intravenous piperacillin-tazobactam was administered.
RESULTS: The patient was discharged without complications.
CONCLUSIONS: Gum elastic bougie is a usable tool in difficult intubation. Adequate pre-anesthesia evaluation, patient sedation, and gentle manipulation assured the intubation success in this case.

UNASSIGNED: Radiation therapy is often accompanied by skin toxicity in the irradiated area and radiation-induced DNA damage to skin tissue cells in the surrounding pigmented area. This case report describes a patient with radiation-induced skin injury who received wound treatment and psychological intervention with satisfactory results. A 60-year-old woman was admitted to the authors\' hospital on January 18, 2021, with radiation-induced skin injury caused by carbon ion radiotherapy for tonsillar carcinoma. The patient underwent wound repair combined with psychological intervention (30 minutes per dressing change). Over a period of 1 month, the wound area was reduced from 11 × 12 cm2 to 1 × 1 cm2, and wound symptoms (exudate, blood odor, wound infection, wound edge dehydration and curling, periwound skin peeling, dryness, and hyperkeratosis) improved. The patient\'s anxiety factor scores decreased from 18 to 1, and her depression factor scores decreased from 16 to 3. When the patient was discharged from the hospital after 1 month of treatment, she had a satisfactory self-image and normal social activities.
