Abstract
Extramedullary plasmacytoma of the larynx is an extremely rare entity accounting for 0.04-0.45% of malignant tumours of the larynx. The objective of this clinical case report is to highlight the diagnosis and management of a unique case such as this. A 77-year-old gentleman presented with complaints of hoarseness for 1 year. Computed tomography image revealed a soft tissue mass lesion involving the right true vocal cord. Direct laryngoscopic biopsy was performed and subjected to histopathological examination, which showed collection of plasma cells. Immunohistochemistry confirmed the presence of Kappa and Lambda cells. Multiple myeloma (MM) was ruled out. The patient received radical intent radiation therapy using 3DCRT technique with a dose of 50Gy in 25# over 5 weeks. He experienced improvement in hoarseness on subsequent follow-up visits. At 1-year follow up, positron emission tomography computed tomography showed near total resolution of disease with no progression to MM. Radiation therapy alone is known to achieve good local control, recurrence free survival, and organ preservation in such cases.

Inflammatory Myofibroblastic Tumor of the Larynx: Report of a Case. J Voice 2023; 37:799.e17-799.e19. [PMID: 34162497 DOI: 10.1016/j.jvoice.2021.04.030] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Revised: 04/12/2021] [Accepted: 04/15/2021] [Indexed: 12/23/2022]
Abstract
PURPOSE Inflammatory myofibroblastic tumor (IMT) is a rare tumor composed of mesenchymal myofibroblastic spindle cells enveloped by an inflammatory infiltrate. Historically, this tumor sparked debate regarding whether it was a true malignancy with metastatic potential or merely a locally destructive physiologic inflammatory response. Few reports of IMT exist in the recent literature, with the majority of cases occurring in the pediatric population and favoring the lungs. Here we present an exceedingly rare case of IMT involving the larynx of a 22-year-old female. RESULTS A hemorrhagic and solid mass of the right true membranous vocal fold was excised and sent for histopathological assessment. Features of the surgical specimens were diagnostic for IMT. Intralesional steroid therapy was selected for additional treatment. Panendoscopy facilitated surveillance for any additional or recurrent lesions, of which there were none. At 11 months post-excision, follow-up MRI revealed symmetric vocal cords without evidence of any masses. CONCLUSIONS Although rare, laryngeal IMT should be considered in any patient presenting with hoarseness due to a vocal fold mass. Based on the successful treatment of our patient, we suggest that our approach of surgical excision followed by intralesional corticosteroid injection may be an efficacious treatment approach for this rare tumor. However, more research is warranted to elucidate the most effective, safe, and cost-effective treatment approach.

Abstract
Cervical inlet patches (CIP) are common endoscopic findings with uncertain pathogenesis and clinical significance. We aimed to perform a systematic review and prospective study of clinical data and endoscopic findings related to CIP. It was a prospective single-center study conducted between 10/01/2017 and 9/01/2018. Forty patients with histopathologically confirmed CIP were compared with 222 individuals in the reference group. The systematic review was executed in accordance with the PRISMA guideline. Alcohol consumption tended to be higher among patients with CIP (3.0 ± 4.6 vs. 1.9 ± 5.0 standard drinks/week CIP patients and reference group, respectively; p < 0.001). Dysphagia was more frequent among patients with CIP (25% vs. 1.4%, CIP patients and reference group, respectively; p < 0.001), and sore throat and hoarseness were less frequent in patients with CIP (17.5% vs. 26.6% CIP patients and reference group, respectively; p < 0.01). In the multivariate regression analysis, the only risk factor of CIP occurrence was dysphagia (OR 21.9, 95%CI 4.9-98.6; p < 0.001). Sore throat and hoarseness were a reverse-risk factor of CIP diagnosis (OR 0.3, 95%CI 0.1-0.93; p = 0.04). Clinical data and coexisting endoscopic findings were not related to CIP. In the presented study, dysphagia was related to CIP occurrence, and sore throat and hoarseness tended to be less frequent among patients with CIP.

Abstract
UNLABELLED The voice as the most important means of communication is of great importance in a person's life. Every year the number of specialties for which voice and speech are a key tool of professional activity increases. Diseases of the vocal apparatus reduce the ability to work, and for some people pose a threat of professional unfitness. The relevance of the study is determined not only by the significant prevalence of dysphonia, but also by the insufficient effectiveness of existing methods of treating voice disorders. OBJECTIVE To evaluate the clinical efficacy and safety of the use of the drug Homeovox in patients with acute and chronic catarrhal laryngitis as monotherapy. To fulfill the set goal of the study, the following tasks were solved: evaluation of the clinical effectiveness of the drug Homeovox as monotherapy for various types of dysphonia; evaluation of the effectiveness of the drug Homeovox as monotherapy from the 1st day of use. MATERIAL AND METHODS The basis for the implementation of the tasks was the analysis of the results of the examination and treatment of 60 patients with voice disorders aged 18 to 75 years. Among them, 10 (17%) patients with acute laryngitis and 50 (83%) patients with chronic laryngitis. To establish the diagnosis, a comprehensive examination was carried out, involving examination, videolaryngostroboscopy, acoustic analysis of the voice. The study design included three patient visits, during which the functional state of the vocal apparatus was examined by subjective and objective methods. RESULTS As a result of the treatment with the use of the drug Homeovox, the efficacy and safety of this drug in the treatment of dysphonia in adult patients with acute and chronic laryngitis from the first days of therapy has been proven, which is confirmed by the method of videolaryngostroboscopy and acoustic analysis of the voice. CONCLUSION The drug Homeovox is an effective, safe remedy and can be included in the complex treatment of laryngeal pathology in order to increase its effectiveness and achieve a therapeutic effect in a shorter time, manifested by an improvement in the clinical and functional state of larynx.

Abstract
Hoarseness is a common problem, typically of transient nature. When hoarseness does not resolve, or when it is associated with concerning symptoms, it is important to consider a wide differential and refer to an otolaryngologist. This article discusses the physiology of the voice and possible causes of dysphonia, and explores when it warrants further work-up by ENT. A discussion of diagnostic techniques and the myriad of tools to treat hoarseness follows. Additionally, the role of reflux in dysphonia is examined with a critical eye to aid in accurate assessment of the patient's complaint.

Effects of Vocal Fold Nodules on Glottal Cycle Measurements Derived from High-Speed Videoendoscopy in Children. PLoS One 2016; 11:e0154586.

Abstract
The goal of this study is to quantify the effects of vocal fold nodules on vibratory motion in children using high-speed videoendoscopy. Differences in vibratory motion were evaluated in 20 children with vocal fold nodules (5–11 years) and 20 age and gender matched typically developing children (5–11 years) during sustained phonation at typical pitch and loudness. Normalized kinematic features of vocal fold displacements from the mid-membranous vocal fold point were extracted from the steady-state high-speed video. A total of 12 kinematic features representing spatial and temporal characteristics of vibratory motion were calculated. Average values and standard deviations (cycle-to-cycle variability) of the following kinematic features were computed: normalized peak displacement, normalized average opening velocity, normalized average closing velocity, normalized peak closing velocity, speed quotient, and open quotient. Group differences between children with and without vocal fold nodules were statistically investigated. While a moderate effect size was observed for the spatial feature of speed quotient, and the temporal feature of normalized average closing velocity in children with nodules compared to vocally normal children, none of the features were statistically significant between the groups after Bonferroni correction. The kinematic analysis of the mid-membranous vocal fold displacement revealed that children with nodules primarily differ from typically developing children in closing phase kinematics of the glottal cycle, whereas the opening phase kinematics are similar. Higher speed quotients and similar opening phase velocities suggest greater relative forces are acting on vocal fold in the closing phase. These findings suggest that future large-scale studies should focus on spatial and temporal features related to the closing phase of the glottal cycle for differentiating the kinematics of children with and without vocal fold nodules.

Abstract
BACKGROUND Lipoid proteinosis is an autosomal recessive disorder characterized by hyalin deposits in the skin and mucosa of the upper aerodigestive tract; currently, no treatment exists. Nearly all patients experience hoarseness and speech difficulties, due to hyalin deposition in the vocal folds and diminished mobility in infiltrated lips, tongue, and palate. METHODS We describe a patient with extensive hyalin plaques on the vocal folds, which resulted in near-aphonic hoarseness. Hyalin deposits in the vocal folds and skin were treated with laser resection. RESULTS Both the vocal folds and skin improved in appearance, with smoother surface epithelium. However, the patient's speech remained impaired, due to extensive hyalin plaques in the mouth, tongue, and lips. The voice improved only temporarily. CONCLUSIONS Laser resection of hyalin plaques in the vocal folds and skin is a feasible treatment for lipoid proteinosis. However, speech may remain severely limited, due to impaired tongue and lip movement.

Abstract
A 52 year old Swiss presented with a sore throat and progressive hoarseness. The histology showed a granulomatous inflammation of the epiglottis. Microbiology revealed dimorphic fungi in the sputum which were identified as Histoplasma sp. The histoplasma antigen was positive in urine and serum. Antimycotic therapy with itraconazol p.o. was started and switched to Amphotericin B i. v. due to clinical deterioration. Adrenal insufficiency should be considered in any patient with disseminated histoplasmosis since both the infection as well as the antimycotic treatment may cause Morbus Addison. An alternative therapy for the disseminated histoplasmosis is voriconazol. The investigation of the travel history is an important point.

Abstract
Laryngopharyngeal reflux of liquid and gaseous gastric contents should be considered in every patient with unexplained hoarseness. Pathophysiology and treatment of reflux-associated laryngitis are different from those of reflux esophagitis and therefore remain an unsolved puzzle. The laryngeal mucosa is considerably more sensitive to acid and pepsin than the mucosa of the esophagogastric junction. Therefore definitions of acid and nonacid reflux used for gastroesophageal reflux disease may not be helpful for explaining pathophysiologic mechanisms in the larynx or pharynx. A reflux symptom index and reflux finding score may be useful in helping to select the minority of patients who may benefit from acid-suppressive therapy; however, further research is needed. Further research is also needed to identify those patients who may require higher doses or prolonged duration of proton pump inhibitors or alternative treatments like prokinetics or alginate, or those patients who may benefit from surgical treatment of gastroesophageal reflux. Since symptoms of laryngopharyngeal reflux may predict esophageal adenocarcinoma, every patient with laryngopharyngeal reflux should have an upper gastrointestinal endoscopy, even if no classical symptoms of gastroesophageal reflux disease are present.

Abstract
Metastatic calcification (MC) commonly results secondary to phosphorus and calcium dysregulation in end-stage renal disease (ESRD). Only once before has MC been reported to involve a true vocal cord. A 35-year-old man with ESRD and secondary hyperparathyroidism was evaluated for hoarseness. Three years ago, he underwent a total parathyroidectomy with parathyroid autograft to the forearm. Simultaneously, he had a left lobe thyroidectomy that displayed a papillary thyroid carcinoma. Since that time, he continued to have hyperphosphatemia and hypocalcemia. Laryngoscopy displayed a small papillomatous lesion on the right true vocal cord. He underwent excision of the vocal cord lesion; histologic examination demonstrated benign squamous epithelium with extensive submucosal calcification. In patients with ESRD with secondary dysregulation of serum phosphorus to calcium level balance, MC may involve variable anatomical locations, including the true vocal cords. Regarding histologic findings, pathologists must consider malignancies associated with calcification, mimicking a benign process.

Abstract
Having a vocal complaint is not uncommon, especially among professional voice users. Medically managing hoarseness is often delayed because the physician or patient fails to understand the vocal behavior that precipitated the voice disorder. Improper breathing and/or abusive vocal patterns are the main predisposing factors to functional voice disorders, the most common category of vocal pathology. Successful management of functionalvoice disorders includes identifying and then modifying aberrant vocal and breathing patterns. Unless these changes are made, a vocal disorder will either persist or commonly recur.

Abstract
The purpose of this study was to elucidate whether misdirected swallowing is an extra-laryngeal cause of hoarseness and investigate whether the prevalence of misdirected swallowing and hoarseness in patients with hiatal hernias differ from those with and without pathological gastroesophageal reflux (GER). One hundred and ninety eight patients with hiatal hernias diagnosed via esophageal manometry and pH-reflux test and 262 subjects in the general population who did not have a hiatal hernia at endoscopy, filled in a questionnaire about symptoms on hoarseness, misdirected swallowing, and heartburn. Hoarseness (35%), misdirected swallowing to the larynx (MSL; 35%), misdirected swallowing to the nose (MSN; 22%) and heartburn (85%) were significantly more common in patients with hiatal hernia than in controls (13, 5, 1, and 6%, respectively, P<0.001). MSL and MSN in the patient group were significantly interrelated (P<0.0001). Hoarseness and MSL were not significantly associated (P<0.076). Hoarseness and MSL were as common in the hernia group with normal GER, as in the group with pathological GER. There is a predisposition for hoarseness and MSL in patients with hiatal hernias, but the cause-and-effect relationship is unclear. Hoarseness does not seem to be caused by pathological GER.

Abstract
The etiology and pathogenesis of laryngeal microwebs are heterogeneous, and in most cases they are an incidental finding. It has also been suggested that microwebs could be a familial trait, representing a postblastogenic embryonic vestigial structure that might alter the biomechanical and vibratory properties of the vocal fold. Vocal nodules are small benign swellings along the margins of the vocal cords, with preferential location at the junction of the anterior and middle thirds, and usually resulting from mechanical trauma. The authors studied a sample of 107 patients with vocal nodules, looking for a possible correlation with microwebs due to the predicted involvement in the vibration of vocal cord margins. Glottic proportion, type of glottic closure, nodule location and the main complaints in patients with microwebs were compared with those in a sample of patients without microwebs. In the present study, microwebs were found in 9.4% of the patients, who showed much smaller glottic proportion than patients with micronodules only. Furthermore, vocal nodule location was not related to the presence and/or absence of laryngeal microwebs.

Abstract
BACKGROUND Determining the dry weight of chronically hemodialysed patients is a common problem. Patients on intermittent hemodialysis often experience transient hoarseness at the end of dialysis. The vocal folds may be affected by the hydration state. AIM To test the hypothesis that postdialysis hoarseness may be related to changes in the thickness of the vocal folds. METHODS Twenty-five stable chronic hemodialysis patients underwent endoscopic nasopharyngeal laryngoscopy before and after dialysis. Pictures of the vocal folds were taken and the folds were measured using computer software. Eighteen vocal folds from 16 patients were technically adequate for analysis. The change in the width/length ratio of the vocal folds (W/L) was used as a measurement of the folds' thickness. RESULTS W/L decreased from 0.175 +/- 0.011 before dialysis to 0.152 +/- 0.009 after dialysis (p < 0.01, mean reduction 10.9 +/- 3.8%). Patients' weight decreased by 4.7 +/- 0.3% (p < 0.0001), systolic blood pressure decreased by 15.0 +/- 3.1% (p < 0.001), diastolic blood pressure decreased by 13.0 +/- 3.6% (p < 0.01), and mean blood pressure decreased by 14.1 +/- 3.1% (p < 0.001). Sixty percent of the patients had postdialysis hoarseness, and in 72% of the patients a decrease in the vocal folds' thickness was observed. CONCLUSIONS Chronic hemodialysis patients may experience transient postdialysis hoarseness, and a decrease in the vocal folds' thickness. The latter may result from dehydration.

Abstract
Bronchogenic cysts are rare, benign, congenital lesions that occur as a result of aberrant development of the tracheobronchial tree during embryogenesis. They usually present during the first decade of life and are encountered predominantly within the mediastinum or the lung parenchyma. In a few instances, they appear within the neck mimicking a neoplasm and, depending on their size and site, may also cause acute upper respiratory obstruction. We describe a case of two cervical bronchogenic cysts adjacent to the larynx in a child who presented with a hoarse voice.

Abstract
Intrathoracic segment of the subclavian artery is an unusual location for peripheral arterial aneurysms. They are normally caused by atherosclerosis, medial degeneration, trauma, and infection. We report a case of a patient with right subclavian artery aneurysm presenting with hoarseness. Chest radiograph demonstrated a superior mediastinal mass. Laryngoscopy showed a fixed right vocal cord. By chest computed tomography, magnetic resonance imaging, and angiography, preoperative diagnosis was established as a saccular aneurysm with afferent loop and efferent loop. Patient underwent complete resection of the aneurysm followed by endto-end anastomosis via median sternotomy. Postoperative pathology was consistent with an atherosclerotic aneurysm filled with thrombus. After surgical operation, hoarseness is still continued.

Abstract
A 38-year-old man presented with a recurrent pleomorphic adenoma in the parapharyngeal space invading the skull base 19 years after the first operation for a parotid gland tumor. Stereotactic radiotherapy was performed to control the tumor growth using a marginal dose of 8 Gy and maximum dose of 18 Gy with care taken to minimize the dose to nearby structures. The symptoms were reduced within a few months. Magnetic resonance imaging over 5 years showed that the tumor was controlled with no regrowth. Stereotactic radiotherapy is a therapeutic option for the treatment of pleomorphic adenomas.

Abstract
BACKGROUND Lipoid proteinosis (LiP) is a rare autosomal recessive disorder characterized by a hoarse voice, warty skin infiltration and scarring. Mutations within the extracellular matrix protein 1 (ECM1) gene cause LiP. Since the early 1970s it has been recognized that South Africa has one of the largest groups of LiP patients worldwide, suggesting a probable founder effect. As LiP patients present with considerable clinical variability, this group of patients offers a unique opportunity for genotype-phenotype correlation. OBJECTIVES To assess the clinical features and the molecular basis of LiP in patients from the Namaqualand area of the Northern Cape province of South Africa and to examine molecular evidence for a founder effect. SUBJECTS AND METHODS The LiP patient cohort consisted of 29 Coloured patients from Namaqualand and a further seven Caucasoid patients from other areas of South Africa. The control group included 100 healthy geographically and ethnically matched individuals from Namaqualand. Samples were collected after informed consent and with ethics committee approval from the University of the Witwatersrand. LiP patients were examined clinically and a structured recording sheet was completed. A brief neurological evaluation was also performed. The LiP founder effect was investigated at the molecular level by ECM1 mutation detection and haplotype analysis. RESULTS The most consistent clinical signs for a diagnosis of LiP in this group were a hoarse voice and thickened sublingual frenulum leading to restricted tongue movement. Homozygosity for a nonsense mutation in exon 7 of the ECM1 gene, Q276X, was identified in all patients (Coloured and Caucasoid). Despite this genetic homogeneity, considerable clinical variability in skin presentation and psychiatric involvement was observed. Haplotype analysis using markers from a 9.98-Mb region around the ECM1 locus confirmed the founder effect with a founder core haplotype, 19-Q276X-12 (ND1-ECM1-D1S2343), in all but four LiP-associated alleles (n = 58). A LiP carrier rate of 1 in 9 was observed among the 100 Namaqualand controls, predicting a LiP incidence of 1 in 324 in this community. CONCLUSIONS Although several consistent clinical features in LiP patients homozygous for the Q276X mutation in the ECM1 gene were observed, there remains considerable clinical variability. This suggests the action of genetic and environmental modifiers of disease severity. Strong molecular evidence supports a single founder effect for the high prevalence of LiP in South Africans, both Coloured and Caucasoid.

Abstract
We report a patient with severe laryngeal tuberculosis (LTB) involving thyroid cartilage and combined with whole-bone metastasis. A 57-year-old male had presented only with hoarseness. Radiological findings were indicative of suspected metastasis from a malignant tumor. However, tuberculosis was considered by histopathological findings, and so sputum samples were tested for acid-fast bacilli and purified protein derivatives of tuberculin in order to detect the presence of LTB. A polymerase chain reaction confirmed the diagnosis. Anti-tuberculous medications were effective in resolving the hoarseness, and the removal of the mass in the right wing of thyroid cartilage was confirmed by computed tomography (CT).

Abstract
Lipoid proteinosis is a rare disease that presents with hyaline deposits in many tissues. It involves predominantly the skin and upper aerodigestive tract, presenting with small yellowish papules and hoarseness. It may involve the central nervous system and cause intracerebral calcifications. Laryngeal lesions may resemble singer's nodule or chronic laryngitis. The pathogenesis of the disease is not clear although several studies suggest a defective collagen production and/or lysosomal storage disease. In this article two cases with skin and larynx involvement are reported.

Many variants of papillary carcinoma of thyroid have been described. Identification of some of these may have prognostic implications. Eighty-two cases of papillary carcinoma of the thyroid diagnosed at Armed Forces Institute of Pathology, Rawalpindi over a six year period were reviewed with the aim of identifying these variants. Fifty-eight (70.7%) were classical papillary carcinoma. Thirteen (15.9%) had follicular variant, 6 (7.3%) columnar cell variant and 3 (3.7%) had tall cell variant. The mean age at diagnosis was 27 years for classical papillary carcinoma, 46 years for follicular variant, 61 years for columnar cell variant and 52 years for tall cell variant. The columnar cell variant had a more aggressive clinical presentation than others. Tall cell, columnar cell and diffuse sclerosing variant have a poor prognosis. An effort should be made to identify them on histopathology so that specific therapy can be planned.

Abstract
A 51-year-old woman complained of hoarseness of two years duration. The patient's past medical history was significant for autoimmunological hepatitis and arthritis for which she had not received treatment. Laryngoscopy and laryngeal stroboscopy revealed 'bamboo joint-like nodules' on both true vocal folds. These nodules resembled rheumatoid nodules and were suggestive of a collagen disease. Previous reports have documented that the treatment for such conditions related to collagen diseases is surgical resection. However, we initially attempted to treat the laryngeal lesions systemically with prednisolone. The hoarseness and the bamboo-like nodules disappeared six months after the treatment. Furthermore, the liver function test returned to normal and arthritis completely resolved. Based on our patient's response to this treatment, we diagnosed atypical-SLE and a lupus laryngitis. This case suggests that studies of the larynx may be helpful in the early diagnosis of collagan diseases and that such conditions may respond to systemic treatment.

Abstract
The basement lamina of the epithelium of the true vocal cords of 34 inpatients suffering from chronic laryngitis, Reinke's oedema and squamous cell carcinoma have been investigated with the electron and immunofluorescence microscope. In chronic laryngitis, the lamina fibroreticularis is thickened (due to collagen type VII), corresponding to the clinical finding. In this layer mobile cells of the connective tissue can be found. In cases of Reinke's oedema it is the lamina densa which might be thickened. In this disease, also lamina densa-like material can protrude into the lamina fibroreticularis, and the number of anchoring filaments is increased. In squamous cell carcinoma we found the basement lamina irregularly arranged and folded. The lamina densa was always interrupted by numerous small gaps and in some areas the basement membrane could not be identified over a long distance. Lamina densa-like material was also found between the tumour cells within the epithelium. With the immunofluorescence microscope this material was proven as laminin, collagen type IV and heparan sulfate proteoglycan. Our investigation shows that malignant as well as benign lesions of the true vocal cords are characterised by distinct fine structural findings even concerning the basement lamina.

Abstract
Visceral soft tissue calcification is common in patients with end-stage renal disease. However, metastatic calcification of the true vocal cords has not been described. We present a patient with chronic renal failure and hoarseness in whom an exophytic true vocal cord mass was diagnosed as a metastatic calcification.

Abstract
A laryngocele associated with squamous cell carcinoma of the larynx is reported in a 20-year-old man without a history of smoking. This is the youngest reported case of carcinoma associated with laryngocele in the literature. This association is supported by the patient's young age and his nonsmoking status. However, this case does not appear to support the conclusion that laryngoceles predispose to the development of squamous cell carcinoma. The clinical history supports the tumor obstruction theory, whereby a laryngocele developed from an obstructing carcinoma of the ventricle.

Abstract
Leukocytes and mast cells have been described in the human nasal mucosa and epithelium of the lower airways (Bonneville 1988, Goodman and Lefrancois 1989, Guy-Grand 1991, Denburg 1992). In mast cells, heterogeneity of mucosal and connective tissue mast cells has been observed. In the present electron microscopic study, the epithelium of the upper airways (larynx and nose) of patients, suffering from chronic laryngitis, was examined with special regard to intraepithelial mast cells. Numerous mast cells were found in the stratum spinosum of the true vocal cords showing extensive elongated surface folds that had little contact to epithelial cells. Desmosomes were absent. Mucosal mast cells are characterised by four types of membrane-bounded granules, whereas serosal mast cells only showed two different types of granules and resembled blood basophiles. Migration of connective tissue mast cells into the epithelium could not be observed. According to our findings, mucosal and serosal mast cells belong to different cell lines.

Abstract
A 20-month-old girl showed typical clinical signs of Farber disease: hoarseness since birth, and periarticular subcutaneous painful nodules. Complete deficiency of acid ceramidase activity was found in cultured skin fibroblasts. An electron microscopic examination of a dermal nodule disclosed pathognomonic tubular inclusions in histiocytes. In epidermal cells zebra-body-like and needle-like lysosomal inclusions were found. Their ultrastructure is different from that of the intrahistiocytic lysosomal inclusions. Probably three clinical types of Farber disease may be distinguished according to the symptomatology and the course of the disease: a severe type, an intermediate type and a relatively mild type. The activity of acid ceramidase does not correlate with prognosis of the disease, while a correlation between first appearance of dermal nodules and clinical course appears likely.

Abstract
Electron microscope studies made on biopsy samples of the human vocal cord from patients suffering from chronic hoarseness revealed pathological changes in both the collagen fibrils and the elastic fibres. There was splitting and fracturing of the collagen fibrils and lacuna or cyst formation in the elastic fibres, or even the complete fibre degeneration. Further investigations must be undertaken in order to establish whether the changes observed are of a primary or secondary nature.
