Case presentation
65 Years old female patient named Zakia Ezz EldeinComes to emergency to E.N.T department with severe stridor
with history of laryngoscleroma patient is intubated and admitted to our ICU unit and prepared
for DL under general anathesia planned for debulking of air way obstruction by microdebrider without tracheostomy
Medical history patient is diabetic & hypertensive
O/E ( intra operative) Revealed bulge of both ventricular bands Debulking was done for this bulge under general anathesia
using microdebrider and also by conventional laryngeal forcepsNasal examination was free
After recovery patient extubated without stridor
Biobsy was sent for histopathalogical examination& revealed hyperplastic acanthotic squamous epithelium with moderate chronic non-specific inflamation
C&S revealed klebsilla ( g –ve cocco bacilli)
Then post operative antibiotics adminstration combined with steroid tappering dose
Post operative CT was done showing no air way obstruction
The follow up laryngoscopy was done: It show greenish crusts only in larynx without subglottic stenosis
• Recently patient come with mild dyspnea and hoarsness of voice after years
• Vediostropscopy was done and showing only mild odema of the larynx and greenish crusts in subglottic region and over the true cords
Diagnosis is recurrent laryngoscleroma
laryngoscleroma
History:Von Hebra termed the rhinoscleroma in 1870.Rhinoscleroma is endemic in several parts of
the world. In India, northern parts are affected more than the southern states
Definition: is a chronic granulomatous condition of the nose and
other structures of the upper respiratory tract. Rhinoscleroma is a result of infection by the bacterium Klebsiella rhinoscleromatis.
Epidemiology:FrequencyIt is endemic to regions of Africa (Egypt, tropical
areas), South east Asia, Mexico, Central and South America, and Central and Eastern Europe, but it has been infrequent in the United States
RacePatients of all races can be affected.Sexscleroma tends to affect females somewhat
more than it does males.AgeTypically, rhinoscleroma appears in patients
aged 10-30 years.
Pathophysiologyscleroma is transmitted by means of the direct
inhalation of droplets or contaminated material. The disease probably begins in areas of epithelial transition such as the vestibule of the nose, the subglottic area of the larynx, or the area between the nasopharynx and oropharynx.
scleroma usually affects the nasal cavity, but lesions associated with rhinoscleroma may also affect the larynx; nasopharynx; oral cavity; paranasal sinuses; or soft tissues of the lips, nose, trachea, and bronchi.
The CD4/CD8 cell ratio in the lesion is altered with decreased levels of CD4 lymphocytes; this change possibly induces a diminished T-cell response. Macrophages are not fully activated.
Mucopolysaccharides in the bacterial capsule probably contribute to the inhibition of phagocytosis
Clinical stages:There are four stages of this disease: catarrhal, atrophic,
granulomatousand cicatricial.1. Catarrhal: Foul smelling purulent nasal discharge for
weeksto months.2. Atrophic stage: This stage presents with crusting, whichresembles atrophic rhinitis.3. Granulomatous stage: Multiple granulomatous nodules,which enlarge and coalesce, are seen in nasal mucosa.Subdermal infiltration of lower part of external nose andupper lip gives “woody” feel. These painless nodules arenon-ulcerative and can be found in pharynx, larynx, tracheaand bronchi.4. Cicatricial stage: Fibrosis leads to stenosis of nares,
distortionof upper lip and adhesions in the nose, nasopharynx,oropharynx and larynx. The subglottic stenosis manifestsas respiratory distress.
Clinically:Symptoms Nasal obstruction (most common complaint) Rhinorrhea Epistaxis Dysphagia Nasal deformity Anesthesia of the soft palate Difficulty breathing that progresses to stridor( biphasic ) Dysphonia Anosmia Cogh and expectoration of (greenish crusts)
Signs:Nasal exam The initial nodule is often intra-nasal
and small in size. Rarely, if neglected, it can grow into an exophytic giant tumor, which may obstruct the entire respiratory tract.

Laboratory Studies:o A positive result with culturing in MacConkey
agar is diagnostic of rhinoscleroma. However, culture results are positive in only 50-60% of patients
o Mikulicz cells are large foam cells with a central nucleus and vacuolated cytoplasm containing causative Bacilli .Russell bodies are homogenous eosinophilic inclusion bodies found in the plasma cells
Imaging Studies (CT findings)1. The subglottic area is involved in laryngeal and
tracheal scleroma. The lesions primarily cause concentric irregular narrowing of the airway. In the trachea, cryptlike irregularities are diagnostic of scleroma
2. The lesions are characteristically homogeneous and nonenhancing, and they have well defined edges
3. CT findings in primary nasal and nasopharyngeal rhinoscleroma include soft-tissue masses of variable sizes
Imaging Studies (MRI)In the hypertrophic stage of rhinoscleroma, both
T1- and T2-weighted images show characteristic mild-to-marked high signal intensity.
Treatment: Antibiotic agents Tetracycline is the drug of choice (2 g/day) for 4–6 weeks Other medication1. Ciprofloxacin is a fluoroquinolone with activity
against Pseudomonas species, streptococci, MRSA, Staphylococcus
2. Rifampin inhibits DNA-dependent bacteria by binding to the beta subunit of DNA-dependent RNA polymerase, blocking RNA transcription.
3. Cefixime is a third-generation cephalosporin. It arrests bacterial cell wall synthesis
N.B Repeat if necessary after 1 month.Treatment is stopped only when two consecutive cultures are negative
Corticosteroid agents : (Prednisone (Deltasone, Meticorten, Orasone)
They can be combined to reduce fibrosis Surgical Care:A. Tracheotomy should be considered in patients
with laryngeal obstruction of the third degree (granulomatous stage)
B. Extensive granulomatous lesions are treated by means of open excision by using the laryngofissure approach
C. Surgery and laser therapy are required to treat airway compromise and tissue deformity.
D. Bronchoscopy has a role in the initial treatment of the disease
