Langerhans' cell histiocytosis of the retropharynx: first reported case

Langerhans' cell histiocytosis (LCH) is a rare condition characterised by histiocyte proliferation leading to destructive granulomatous lesions. It may occur anywhere in the body but extraosseous manifestations affecting the head and neck are particularly uncommon. Here, we present the first reported case of a mass arising in the retropharyngeal space caused by LCH. The patient was a 33-year-old man with various symptoms which are presented. Although rare, LCH can affect a variety of tissues in the head and neck. Clinicians need to be cognisant of its inclusion in the differential diagnoses for similar cases in their practice, in particular because of potential difficulties in diagnosis.

Outcomes of 756 patients with differentiated thyroid cancer and excellent response to treatment: An evidence-based paradigm for long-term surveillance strategies

BACKGROUND

The 2014 British Thyroid Association thyroid cancer guidelines recommend lifelong follow-up of all thyroid cancer patients. This is probably unnecessary, particularly for differentiated thyroid cancer (DTC) patients with an excellent response to treatment and places significant demand on health service resources.

DESIGN

Single centre retrospective cohort analysis of patients diagnosed and treated at the Leeds Cancer Centre between 2001 and 2014.

PATIENTS

A total of 756 patients were dynamically risk-stratified (DRS) as having 'excellent response to treatment' after total thyroidectomy and radioiodineremnant ablation (RRA) for DTC.

RESULTS

Median follow-up was 11.2 (range: 6.5-18.5) years. Radiological recurrence occurred in 15/756 (2.0%) patients and was always preceded by a raised thyroglobulin or thyroglobulin antibody level. The vast majority of tumour recurrences (13/15, 85%) were identifiable within 5 years of diagnostic surgery. Patients classified as having high-risk disease as per American Thyroid Association (ATA) guidelines had an almost threefold higher recurrence rate (2/34 [5.9%] vs. 13/722 [1.8%]) than those with ATA low-risk or intermediate-risk disease. Tumour histology subtype was a significant contributing factor, with Hürthle cell cancer having a worse prognosis than papillary thyroid cancer (PTC) (5/68 [7.4%] vs. 9/582 [1.5%]; relative risk: 4.76 [95% confidence interval: 1.64-13.8]).

CONCLUSIONS

The recurrence rate of DRS patients with excellent response to treatment is low. It is reasonable to consider discharge of ATA low-risk or intermediate-risk patients with PTC who remain disease-free after 5 years of secondary care follow-up. Lifelong follow-up, however, currently remains the standard for subgroups at greater risk.

Management of parapharyngeal space cavernous sinus haemangioma using transoral robotic surgery

Cavernous haemangiomas are a very rare occurrence in the parapharyngeal space (PPS). Here, we present a case of a 58-year-old woman with an incidentally identified left PPS mass thought to be a pleomorphic adenoma that underwent excision by transoral robotic surgery (TORS). Intraoperative findings demonstrated no solid mass present and histological assessment of resected tissue confirmed a cavernous haemangioma. We discuss our experience in the management of a radiological and surgical mismatch of a PPS mass in what we believe to be the first cavernous haemangioma to be excised by TORS in this region.

Intraoperative parathyroid hormone monitoring to determine long-term success of total parathyroidectomy for secondary hyperparathyroidism

BACKGROUND

Use of intraoperative parathyroid hormone (ioPTH) monitoring during total parathyroidectomy for secondary hyperparathyroidism is common, although its ability to predict long-term normoparathyroid state is not known.

METHODS

Prospective evaluation of 57 consecutive patients undergoing total parathyroidectomy for renal hyperparathyroidism with ioPTH monitoring and follow-up PTH assays were used to categorize the patients into 3 groups: success, adequate biochemical control, and failure.

RESULTS

There was no statistically significant difference in percentage reduction of ioPTH between the 3 groups (p = .07), although there was a moderate negative correlation between percentage reduction of ioPTH and percentage reduction of PTH at follow-up (R = 0.57).

CONCLUSIONS

When used under current guidelines, ioPTH monitoring is of no use in predicting long-term cure for these patients because it does not predict success. Patients that undergo total parathyroidectomy are required to have long-term calcium and PTH assay follow-up because normoparathyroidism cannot be assumed. Using the regression equation calculated, success may be predicted for future patients.

Extramedullary plasmacytoma of the tongue base: a case report and clinical review of head and neck plasmacytoma

Plasmacytomas of the head and neck are rare tumors characterized by a monoclonal proliferation of plasma cells. Very few cases of plasmacytoma of the tongue base have been reported. We present a new case of extramedullary plasmacytoma of the tongue base, we discuss its diagnosis and management, and we review the literature on plasmacytomas of the head and neck.

Diagnostic biopsy of lymph nodes of the neck, axilla and groin: rhyme, reason or chance?

INTRODUCTION

Improving patient pathways of care is becoming increasingly important in the delivery of timely, appropriate surgical care. With this aim, we analysed the referral and management pathway of patients undergoing diagnostic superficial lymph node biopsy.

PATIENTS AND METHODS

A retrospective review of case notes of patients undergoing diagnostic superficial lymph node biopsy over 3 years, 1998-2000 at the Bradford Hospitals NHS Trust. Indication for surgical biopsy was based on clinical suspicion following assessment in the out-patient clinic for the majority, and arrangement of investigations as deemed appropriate. There were no clinical algorithms in use during the study period.

RESULTS

There was no evidence for the use of explicit protocols for referral or management. Biopsy was often delayed. Of 268 patients referred from primary care, referral was made to any of 14 hospital Department with 39% (105 of 268) attending more than one outpatient appointment, and 155 (41 of 268) attending more than one department. Eighteen percent (47 of 268) of patients were informed of their diagnosis within 6 weeks of referral and 42% (113 of 268) within 3 months of referral. Nine percent (24 of 268) underwent pre-operative fine needle aspiration cytology. Of patients with enlarged neck nodes, 29% (52/180) had examination of the upper aero-digestive tract.

CONCLUSIONS

The study supports the introduction of co-ordinated problem-based referral and management pathways for the management of patients with enlarged superficial lymph nodes supported by regular audits of practice.

Dysphagia with a thyroid nodule: is there a primary aerodigestive malignancy?

Three cases of laryngopharyngeal primary squamous cell carcinoma presenting with thyroid nodules are described. The key message to take away from these cases is that patients with advanced malignancy of the upper aerodigestive tract can present with a thyroid nodule.

A quartet of lateral sinus thrombosis, extradural abscess, subdural abscess and occipital abscess: complications of acute mastoiditis in a pre-adolescent child

Neurological complications of acute mastoiditis are rare but can be life threatening. Their presentation may be masked by the use of antibiotics. We present a unique case of acute otitis media progressing to occipital, extradural and subdural abscess formation and lateral sinus thrombosis in a child. The clinical course and management of a pre-adolescent male is presented and discussed. We review the incidence, presentation and treatment of occipital abscesses and lateral sinus thrombosis with acute mastoiditis. Following extended cortical mastoidectomy, neck exploration and broad spectrum intravenous antibiotics, the patient made a full recovery. This is the first reported case of acute mastoiditis associated with occipital abscess in a child. Early, aggressive treatment is required for a successful outcome. The rarity of neurological complications, in addition to the insidious onset and subtle symptoms associated with antibiotic therapy, can make diagnosis extremely difficult. Patients with acute otitis media who fail to respond fully to treatment should be referred early for a specialist otology opinion.

Growth hormone abuse and bodybuilding as aetiological factors in the development of bilateral internal laryngocoeles. A case report

A 36-year-old man presented with hoarseness and stridor. He was an elite professional bodybuilder and admitted to having abusing anabolic steroids and growth hormone in the recent past. A CT scan showed bilateral laryngocoeles. The patient was initially managed with intravenous corticosteroids and broad-spectrum antibiotics, and the stridor resolved sufficiently to permit discharge from the hospital. He proceeded to undergo endoscopic marsupialisation of his laryngocoeles and to date has made a full recovery. This is the first reported case where anabolic steroid and growth hormone abuse combined with an elite bodybuilder's exercise regime has been implicated in the aetiology of bilateral laryngocoeles.

Mucinous intestinal type adenocarcinoma of the sinonasal tract secondary to passive wood dust inhalation: case report

A 76-year-old female patient with a mucinous intestinal type adenocarcinoma of the sinonasal tract is described. The probable aetiology of passive hard wood dust inhalation, investigations carried out and subsequent surgical treatment using a transfacial access approach and a temporoparietal fascial composite free flap in conjunction with free auricular cartilage are described.

Soft tissue deposits in neck dissections of patients with head and neck squamous cell carcinoma: prospective analysis of prevalence, survival, and its implications

BACKGROUND

Soft tissue deposits of squamous cell carcinoma in the necks of patients with squamous cell carcinoma of the upper aerodigestive tract may represent either total effacement of a lymph node by carcinoma or extralymphatic deposits of carcinoma. There are few reports of their clinical or prognostic significance.

METHODS

Data from 215 neck dissections from 155 patients with squamous cell carcinoma of the upper aerodigestive tract were studied prospectively to assess the prevalence of soft tissue deposits within the neck. The case notes of these patients were subsequently reviewed to analyze the effect on both the overall survival and recurrence-free survival.

RESULTS

The prevalence rate for soft tissue deposits occurring alone was 10.3%; the prevalence rate for soft tissue deposits occurring with extracapsular spread was 13.5%. The overall prevalence rate for soft tissue deposits was 23.9%. There was a statistically significant reduction in actuarial and recurrence-free survival in patients with soft tissue deposits compared with patients with pathologically node-negative necks (P=.001), and in patients with soft tissue deposits compared with those with pathologically node-positive necks without extracapsular spread (P=.001). No statistically significant differences were found between patients with soft tissue deposits and patients with pathologically node-positive necks with extracapsular spread, for actuarial survival or recurrence-free survival.

CONCLUSIONS

In this series, soft tissue deposits were associated with an aggressive clinical course and poor survival. It is therefore important that histopathologists agree on a uniform terminology when reporting soft tissue deposits and actively look for their presence when examining neck dissection specimens.

Upper aerodigestive tract squamous cell carcinoma: distribution of extracapsular spread and soft tissue deposits in the neck

OBJECTIVE

Extracapsular spread (ECS) and soft tissue deposits (STD) of squamous cell carcinoma (SCC) in the neck of patients with metastatic SCC of the upper aerodigestive tract have been shown to adversely affect actuarial and disease-free survival. No studies to date have detailed the distribution of ECS and STD within the neck.

MATERIAL AND METHODS

A total of 215 neck dissections from 155 patients were prospectively collected and analysed for the presence of both STD and ECS. As no classification for STD exists, their distribution was classified according to the nodal levels used for classification of cervical lymph nodes as described by the Memorial Sloan-Kettering Cancer Center.

RESULTS

A total of 81 neck dissections from 59 patients were found to have either metastatic lymph nodes with ECS, STD or both. The distribution of lymph node metastasis, ECS and STD was very similar. Level II was most frequently affected, with Levels III and IV being affected less frequently. There were very few lymph node metastases to Level V, and this level contained no evidence of either ECS or STD.

CONCLUSION

The method of pathological assessment of neck dissection specimens and reporting on the presence of ECS and STD has not been formalized. By analysing neck dissection specimens in the manner described we can report on the presence or absence of ECS and STD with increased accuracy. This has considerable implications for patient management.

Limited form of Churg-Strauss syndrome presenting as a mass in the neck

A 53-year-old man was referred to the ENT department with a large mass in the left supraclavicular fossa. The histological diagnosis showed the mass to have arisen due to a granulomatous vasculitis consistent with Churg-Strauss syndrome (CSS). CSS usually comprises asthma, eosinophilia and systemic vasculitis although limited forms of the disease exist where one of these diagnostic criteria is missing. This is one such case as the patient was non-asthmatic.
