From the Radiological Department, University of Alexandria, Egypt S C L E R O M A is a specific g r a n u l o m a affecting, mainly, the nose. T h e u p p e r air-passages, trachea, a n d b r o n c h i m a y also b e involved, e i t h e r w i t h or w i t h o u t a p p a r e n t c o n t i n u i t y w i t h t h e nasal granuloma. Histologically, the lesion has a characteristic appearance. T h e c o r i u m a n d s u b m u c o s a are infiltrated b y g r a n u l o m a t o u s tissue c o m p o s e d of: (a) Vacuolated f o a m y histiocytes (Mikulicz cells); (b) P l a s m a cells; (c) D e g e n e r a t e d hyalinized p l a s m a cells (Russel's bodies) ; (d) N e u t r o p h i l s ; (e) A v a r y i n g n u m b e r of capillaries; a n d ( f ) Fibrocytes, fibroblasts, a n d collagen. Yasenetskiy a n d Y a m o p l o s k a y (1956) s h o w e d t h a t t h e degree of sclerosis is n o t indicative of t h e age of the pathological process. I t can o c c u r i n very early lesions, whereas active cellular infiltrations m a y b e f o u n d in old granulomas. T h e causative a g e n t is suggested to b e a strain of the F r i e d l a n d e r ' s bacillus ( F r i s c h bacillus, Bacillus mucosus capsulatus, or Bacillus rhinoscleromatis). T h e o r g a n i s m s c a n always b e r e c o v e r e d f r o m g e n u i n e cases of scleroma ( C u n n i n g , 1949; Falcao a n d Preto, 1947; and Gugid, 1956). T h e m o d e of infection is u n c e r t a i n . M a n - t o - m a n infection is n o t confirmed. T h e o r g a n i s m s could b e f o u n d in t h e soils of gardens of p a t i e n t s w i t h scleroma a n d oz~ena in e n d e m i c areas ; t r a n s m i s s i o n t h r o u g h t h e cultivated soil was, therefore, suggested (Guild, 1956). S c l e r o m a is a n e n d e m i c disease p r e v a l e n t in E a s t e r n Europe, Russia, S o u t h America, a n d certain Far E a s t e r n islands. I t can b e c o n s i d e r e d e n d e m i c in Egypt. T h e p r e s e n t r e p o r t deals w i t h the clinical a n d radiological s t u d y of 84 cases of s c l e r o m a seen a n d treated b y X rays d u r i n g t h e years 1951-6, in the Radiotherapy Department of t h e Alexandria U n i v e r s i t y Hospitals. All cases were histologically proved.

Nasal o b s t r u c t i o n of a varying degree of severity was p r e s e n t in all cases of rhinoscleroma. T h e o b s t r u c t i o n was unilateral in 9 cases.

c. Nasal expansion and deformity. A characteristic deformity can be produced by rhinoscleroma, viz., expansion of one or both sides of the nose and nares, with broadening, depression, and flattening of the nasal bridge (Fig. 3). A discharging sinus was seen at the junction of the nasal bones and cartilages on either side in i instance. In another patient the expansion of the ethmoid
air cells, together with left chronic dacryocystitis, produced bilateral inner canthal swellings (Fig. 4). d. Nasal bleeding: actual epistaxis occurred in 9 cases. Blood-stained discharge is more common, and was complained of by 55 patients. e. Nasal discharge: all patients of rhinoscleroma complained of some form of nasal discharge. Fcetor,

h. T h e radiographic signs: t h e following signs m a y b e detectable : - i. T h i c k e n i n g of the nasal m u c o s a ; this m a y take the f o r m of either diffuse t h i c k e n i n g parallel to the b o n y b o u n d a r i e s or polypoidal f o r m a t i o n (Figs. 5, 6). ii. E x p a n s i o n of the nasal cavity a n d t h e vestibule was detected in 36 p a t i e n t s (Figs. 5, 6). T h e lateral nasal b o n y b o u n d a r i e s a n d t h e nasal b o n e s were t h i n n e d a n d displaced outwards. I n one i n s t a n c e these changes were localized to t h e lower p a r t of the r i g h t nasal fossa (Fig. 7). I n a n o t h e r instance sclerosis a n d t h i c k e n i n g of t h e nasal b o n e s were noted. T h i s was due to a n e l e m e n t of s e c o n d a r y infection, as clinically t h e r e was a sinus o n e i t h e r side at t h e j u n c t i o n of t h e nasal bones a n d cartilages (Fig. 8).

the hard palate b y a granuloma of the nasal floor was seen twice. A t first the soft palatal granuloma forms a p l u m p spindle-shaped swelling (Figs. 9, i i , I2, I3). Later, fibrosis will cause its contraction, pitting, and irregularities, especially of the dorsum of the soft palate and uvula (Fig. i4). In one patient adhesions developed b e t w e e n the posterior pharyngeal wall and the soft palate. 4. Pharyngoscleroma.--In all except 2 cases of pharyngoscleroma there was an obvious continuity w i t h the nasal lesion across the posterior nares. T h e lateral wails of the nasopharynx are the c o m m o n e s t sites of affection. In i instance the granuloma extended d o w n w a r d s to the posterior wall of the oropharynx. T i n n i t u s and Eustachian tubal deafness were complained of b y 8 patients. 5. Laryngoscleroma.--In this series there are 2 examples of pure laryngoscleroma.

Ozcena and atrophic rhinitis may be the end stage of scleroma. Active granulomatous infiltrations m a y coexist with areas of atrophic sclerosed nasal mucosa. T h i s combination m u s t be carefully observed before radiation therapy. Bacteriological and histological examination will reveal such a combination. Radiotherapy of S c l e r o m a . - - V a r i o u s chemotherapeutics and antibiotics have been tried in the treatment of sclerorna. T h e general opinion is that the known antibiotics help to clear up the associated secondary infection, with little or no effect on the scleromatous lesion (Cunning, 1949; and Pradilloj, 1956), T w e l v e of our cases have received streptomycin treatment for periods varying from 2o-5o days before radiotherapy without apparent improvement, X - r a y therapy was the main line of treatment in our cases. A n X - r a y beam of a H . V . L . = 1"o5 ram. Cu. was used. T h e arrangement and size of the X - r a y portals were adapted to the distribution of the lesions in the individual cases.
