Laryngeal involvement in pemphigus vulgaris: a proposed classification

Objective: (1) To investigate the incidence of laryngeal involvement in a large series of patients with pemphigus vulgaris, using endoscopic examination, (2) to describe the lesions, and (3) to establish a classification of laryngeal involvement in pemphigus vulgaris based on the location of the lesions. Study design: Prospective study. Methods: A total of 40 sequentially treated pemphigus vulgaris patients, diagnosed using clinical, histological and immunofluorescence criteria, were evaluated for laryngeal manifestations using endoscopic examination. The results were used to establish a graded classification of laryngeal involvement according to the location of the lesions. Results: Active laryngeal lesions (ulcers or blisters) were found in 16 patients (40 per cent). Of these, 37.5 per cent were classified as grade I, 20 per cent as grade II, 20 per cent as grade III and 17.5 per cent as grade IV. Conclusion: Laryngeal involvement is common in pemphigus vulgaris and must be considered at the point of diagnosis. Grade I lesions are the most frequent.     

Laryngeal papillomas: classification and course

Seventy-one cases of laryngeal papillomas have been reviewed. Based on differences in age at presentation, female: male ratio and multiple versus solitary papillomas, the cases were classified into 4 groups: multiple juvenile papillomas, solitary juvenile papillomas, multiple and solitary adult papillomas. The clinical course in the groups is described. The authors do not support the common opinion that juvenile papillomas are influenced by puberty.     

Laryngeal papillomas: clinical aspects in a series of 231 patients

The records of 231 patients with laryngeal papillomas were reviewed. Considering age at onset and sex distribution, the patients were divided into four groups: juvenile solitary, juvenile multiple, adult solitary, and adult multiple papillomas. The main conclusions are (1) it is in general impossible to predict the course in individual cases, but solitary papillomas in adults follow a less severe course than do juvenile and adult multiple cases; (2) late recurrences (up to 42 years) makes it impossible to declare a patient cured; (3) there is no linkage between puberty and the disappearance of laryngeal papillomas; (4) a latent infection, acquired at or before birth, is unlikely to be responsible for adult papillomas.     

The clinical relevance of classification of squamous cell hyperplasia of the larynx by morphometry

By means of morphometry, differentiation between the classes of laryngeal squamous cell hyperplasia can easily be performed, mutually (Kleinsasser's classification) and in comparison with normal epithelium. It is rather difficult, however, to distinguish between class II (hyperplasia and atypia) and class III (carcinoma in situ). In the group of class II lesions, two groups of patients could be differentiated: a prognostically favourable and an unfavourable group. When using a linear discriminant analysis, the two groups mentioned could be distinguished morphometrically. In histopathological examination, lesions classified as hyperplasia and atypia (class II), must also be examined with morphometry, because in this way the group at risk can be traced.     

Comparison of the clinical relevance of traditional and new classification systems of temporal bone fractures

Temporal bone fractures are traditionally classified as transverse, longitudinal or mixed. Since these categories have shown little association with clinical symptoms, new classifications have been introduced, including those related to the involvement of the petrous bone and otic capsule. We have formulated a new classification based on the involvement of four parts of the temporal bone (squama, tympanic, mastoid, and petrous) and assessed which of these classification systems is the most rational using a retrospective chart review in hospital settings (KyungHee Medical Center, Seoul, Korea and Samsung Changwon Hospital, Changwon, Korea). The association between each classification and clinical symptoms was examined by analyzing temporal bone computed tomography scans of 129 patients diagnosed as temporal bone fractures over the past 7?years. Using the traditional classification, there was a significant correlation between transverse fractures and the incidence of sensorineural hearing loss. Patients with petrous bone fractures had significantly higher incidence rates of sensorineural hearing loss, vertigo, and eardrum perforation than patients without petrous bone involvement. Involvement of the otic capsule was significantly associated with sensorineural hearing loss and the severity of hearing loss. The associations of the traditional classification and the classification according to the involvement of the otic capsule, four parts of temporal bone with clinical symptoms were not high. Petrous bone fractures were significantly associated with sensorineural hearing loss, vertigo, and eardrum perforation, suggesting that this classification may be optimally associated with clinical symptoms including hearing and the results of otological examination.     

First branchial cleft cysts: clinical update

First branchial cleft cysts develop as a result of incomplete fusion of the cleft between the first and second branchial arches and give rise to two distinct anomalies, termed type I and type II anomalies. Type I anomalies are purely ectodermal while type II anomalies exhibit ectodermal and mesodermal elements. The type II anomaly incorporates some portion of the first and second arch as well as the cleft. Type I lesions are extremely rare. They appear histologically as cysts lined by squamous epithelium. Clinically, they present as a cystic mass or fistula posterior to the pinna and concha. The cyst is usually superior to the main trunk of the facial nerve and ends in a cul-de-sac on or near a bony plate at the level of the mesotympanum. Type II lesions are more numerous and represent a duplication of both membranous and cartilaginous portions of the external auditory canal. They contain skin as well as adnexal structures and cartilage and may be associated with the parotid gland. Most frequently they are associated with fistulae in the concha or external auditory canal as well as fistulous openings in the neck.     

Laryngeal papillomatosis: clinical, histopathologic and molecular studies

The clinical course and pathology of 57 patients with laryngeal papillomatosis were reviewed. Tissues from 26 patients were analyzed for human papillomavirus (HPV) DNA by Southern blot hybridization. Histopathologic evaluation of the papillomas showed no correlation with age of onset or clinical pattern of remission and recurrence. The pathology was characterized by abnormal squamous maturation with parakeratosis, retardation of superficial cell maturation, papillomatosis, and basal hyperplasia. HPV DNA was present in all lesions, with 92% containing either HPV-6 or 11. Latent HPV DNA was detected in clinically uninvolved tissues of 11 of 14 (78.5%) patients studied. There was no correlation between HPV type, histopathology and/or clinical pattern. Despite homogeneity of pathology, the clinical expression of laryngeal HPV infection varied widely. A mechanism for the pathogenesis of laryngeal papillomatosis, based on the concept of maturational arrest, is proposed.     

Laryngeal fractures: clinical findings and considerations on suboptimal outcome

CONCLUSION: We recommend early surgical exploration and fixation for patients with dislocated or comminuted laryngeal fractures to avoid long-term voice complications. One-third of 33 fracture patients rated their voice after the fracture had healed as fair but altered. OBJECTIVES: To examine the indications for and the outcome of surgical management in patients with laryngeal fractures. PATIENTS AND METHODS: The study was carried out in a tertiary care referral university hospital and was a retrospective study of case series. Thirty-three consecutive patients, aged 14-84 years, presented with various types of laryngeal fractures. Patients were staged according to the type of the fracture and surgical correction was performed when indicated. Voice outcome was documented and patients with subjectively suboptimal result were further evaluated by phoniatric specialist. RESULTS: In all, 32 of 33 laryngeal fracture patients had blunt trauma and the main causative factors were sport injuries (39%) and physical assault (33%). All of the 33 laryngeal fracture patients had a good airway outcome. The subjective voice outcome was good for 20 (61%) and fair for 13 (39%) patients. The mean follow-up time was 39.5 months (range 2-114 months). In phoniatric evaluation most (six of eight) patients with fair voice outcome could not produce high pitched voices because of inability to stretch the vocal folds.

Laryngeal sarcoidosis: a case report

Sarcoidosis is a chronic multisystemic granulomatosis of unknown etiology that affects mainly young adults. It characterized by bilateral hiliar adenopathies interstitial pulmonary infiltrate, and cutaneous and ocular lesions. Localization in upper respiratory tract is infrequent. In the present report we describe a 26-year-old male with a three-month history of a globus sensation, hoarse voice, loud snoring and obstructive sleep apnoea, because of a laryngeal noncaseating granulomatous infiltration. The diagnosis is made through the history, the radiology and the pathological examination. Treatment is symptomatic, due to its tendency to a spontaneous regression. The treatment is based on corticosteroids by systemic or aerosol routes. Micro surgical excision and tracheotomy may be useful in selected patients.     

Laryngeal syphilis: a case report

Syphilis is a sexually transmitted disease caused by the spirochete Treponema pallidum. The complexity of the disease gained it the moniker "the great imitator"; it was William Osler who said, "He who knows syphilis, knows medicine." In 1866, Patrick Watson of Edinburgh, Scotland, reported a case of a 36-year-old man in whom syphilis destroyed the larynx.(1) The diagnosis was made postmortem. It was once believed that this was the first reported total laryngectomy, but the credit should actually be given to Christian Albert Theodor Billroth who performed this surgery on a patient with laryngeal carcinoma in 1873.     

Laryngeal neurilemmoma: a case report

Published reports of benign nerve sheath tumors of the larynx are extremely rare. Because these tumors represent a potential threat to the airway, prompt diagnosis and treatment are vital. We report a case of a neurilemmoma that arose from the right arytenoid muscle adjacent to the arytenoid cartilage. The mass was completely excised, and no recurrence was observed during follow-up. We discuss the diagnosis and management of this rare tumor.     

Laryngeal amyloidosis: a case report

We report a case of Amyloidosis of larynx in a 60-year-old adult who reported to us with hoarseness of voice of 3?years long duration and no other symptoms. Patient was treated successfully with endoscopic curettage of the mass with no inadvertent ill effects.     

Laryngeal tuberculosis: a case report

The laryngeal tuberculous is the most frequent granulomatous disease of the larynx. It is generally associated with a pulmonary cave, and represents a prognosis element extremely serious and can be complicated extreme dysphagia and pains. Among all the extrapulmonary localisations. The isolated laryngée localisation is rare. It is secondary the dissemination coming hematogen, air or lymphatic way. All the structures of the larynx can be reached. The beginning is progressive and insidious and appears by the dysphony, cough, the odynophagy and dyspnea. We report the case of laryngeal tuberculosis in a 21 year old young man. The authors point out the characteristics of this localization and insist on the biopsy in front of any chronic laryngitis no aetiology. The treatment is medical.     

Laryngeal tuberculosis: report of a case

The larynx as a site of tuberculosis represents less than 1% of the total of this disease. Primary tuberculous laryngitis is even more rare. The authors report a case of an 89 year-old man presenting with swallowing disorders (dysphagia and overspill) consulting for suspected laryngeal carcinoma. Finally, the diagnosis was laryngeal tuberculosis. The outcome was favourable with appropriate treatment, obtaining complete healing without any after-effects. The diagnosis of tuberculosis must cross the clinician's mind, even when there are no general symptoms.
