The clinical study of 183 cases of laryngeal mass was observed and 88 cases of vocal nodule and polyp which is confirmed histopathologically, were clinically classified into 30 cases of vocal nodule, 48 cases of localized vocal polyp, 10 cases of diffuse vocal polyp, and the following results of microscopic examination were obtained. I. The clinical study of laryngeal mass 1. Among total cases of 183, vocal nodule is 82(45%) vocal polyp 53(29%) postintubation granuloma 3(1%) laryngeal papilloma 18(10%) tuberculosis 2(1%) cancer 25(14%). 2. The sex ratio of male to female is 3:4 in vocal nodule, 1:1 in vocal polyp, 1:2 in postintubation granuloma, 3:2 in laryngeal papilloma, 11:1 in cancer. 3. The age distribution is third-fourth decade in vocal nodule, fourth-fifth decade in vocal polyp, third decade in postintubation granuloma, second and fifth decade in laryngeal tuberculosis, sixth decade in laryngeal cancer. 4. The distribution of symptoms is 5 month. -1 year in vocal nodule and polyp, less than 1 year in laryngeal papilloma and postintubation granuloma, 1 year-3 year in laryngeal tuberculosis and cancer. 5. The location of the lesion is between the anterior 1/3 and middle 1/3 in vocal nodule and polyp and papilloma, middle 1/3 and posterior 1/3 in postintubation granuloma, and is diffusely spread on the entire vocal cord in laryngeal tuberculosis and cancer. 6. The side of the lesion is bilateral in vocal nodule and papilloma and the ratio of right to left is 5:3 in vocal polyp, 2:1 in postintubation granuloma. 7. The size is 1~2mm(67%) in vocal nodule, 3~5mm(42%) in vocal polyp, 6~10mm (67%) in postintubation granuloma, 1~2mm (39%) in papilloma, more than 10mm in tuberculosis and cancer. 8. Among the symptoms, the hoarseness is in more than 90% of disease entity, the sore-throat in tuberculosis and cancer, the dyspnea in postintubation granuloma and papilloma and tuberculosis and cancer. 9. In the past history, certain relationship with smoking is noted in cancer (40%) and tuberculosis(50%) and the history of frequent attack of URI is in papilloma(33%). 10. In occupation, certain statistical significance was not noted. II. The histopathological study of vocal nodule and polyp. 1. Most polyps and nodules were covered with stratified squamous epithelium, but focal hyperkeratosis, parakeratosis, acanthosis and atrophy were rather frequently observed. Hyperkeratosis and acanthosis was most frequently seen.

Aspergillus fumigatus is associated with invasive disease aspergillosis in immunocompromised individuals. The major aim of this study was to investigate the biochemical and immunological responses of male Wistar rats against A. fumigatus experimentally-induced pulmonary fungal infection. Nostril experimental exposure of male Wistar rats to a high dose of A. fumigatus freeze-dried preparation for only 24 hr resulted in a significant increase in levels of catalase, nitric oxide and lipid peroxide in lung homogenates, compared to those of the control animals. However, the oxidative status of the lungs of rats challenged with killed fungus did not change significantly, except for the stimulation in the level of lipid peroxide. IgG level was significantly elevated only in rats that received two low doses of fungus, compared to unexposed animals (p < 0.005). Examining the lung of rats exposed to A. fumigatus revealed no abnormal changes, except for pus in bronchial lumen spaces and per bronchial inflammation. Histologically, large numbers of granuloma cells were evident in the lungs of challenged rats, while no granuloma formation was evident in the lungs of rats exposed to killed fungus.

Purpose: Langerhans cell histiocytosis is a heterogenous group of Langerhans cell proliferative disorders and includes eosinophilic granuloma, Letterer-Siwe diseases, and Hand-Schuller Christian disease. We report a case of eosinophilic granuloma on frontal area. Methods: A 17-year-old male presented with swelling and tenderness on Lt. frontal and periorbital area. CT and MRI showed a $33{\times}25mm$ sized mass that involved Lt. frontal calvarium, frontotemporal meninges, and orbital roof. Results: Total excision of the mass and adjacent soft tissue, calvarium, and orbital roof was performed. Orbital roof defect was reconstructed with absorbable plate and calvarial defect was done with outer cortex of temporal bone flap. The histology revealed proliferation of histiocytes and eosinophils. Immunologically, these histiocytic cells expressed S-100 protein and CD1a. The patient is currently taking conservative treatment. Conclusion: The severity of these disease and their prognosis and treatments are various. For unifocal cranial Langerhans cell histiocytosis, complete excision is the treatment of choice. We report this case with review of literature.

Histiocytosis X is the abnormal proliferation of histiocytes and usually a massive aggregation of eosinophilic leukocytes. The clinical features and prognosises of subclasses of histiocytosis X depend on the severity and extent of the organ involvement. The subclasses include Letterer-Siwe disease(Acute disseminated histiocytosis X), eosinophilic granuloma, Hand-Schuller-Christian disease. Letterer-Siwe disease(acute, subacute form) refers to the form of disease that is most often fatal because of the widespread skeletal, extraskeletal lesion ; this usually affects infants and children less than 3 years of age. Eosinophilic granuloma(histiocytosis X, localized) refers to a chronic form of disease with skeletal lesion ; It usually affects children and young adult. Hand-Schuller-Christian disease(chronic form) refers to a chronic form of disease with skeletal, extraskeletal lesions. It usually affects children over the age of 3 years. In our hospital, 8 year old female patient visited complaining of hard swelling of mandibule body, left side and 6 year old female patient visited complaining of painful swelling of mandibular angle, right side. We diagnosed eosinophilic granuloma and curetted the lesiones and refered to Dept. pediatrics for chemotherapy. We present 2 cases to you with literatures.

Traumatic neuromas are rare benign tumors that are common after trauma or surgery and are usually accompanied by obvious symptoms of pain. Most reports show neuromas in the face, neck, and limbs, and the traumatic neuroma of the medial plantar nerve has rarely been reported. We encountered a traumatic neuroma of the medial plantar nerve after a deep laceration mimicking a foreign body granuloma. A small mass lesion was found around plantar aponeurosis with heterogeneous high signal intensity in the T2 fat suppression view and slightly enhanced intensity in the magnetic resonance imaging that suggested a foreign body granuloma. The lesion was diagnosed pathologically as a traumatic neuroma. A satisfactory clinical result was obtained after excision of the traumatic neuroma and burial of the proximal and distal stumps to the adjacent muscle at the secondary operation.

Seven patients having midline granuloma received local irradiation from March 1983 to June 1986. Clinically, all of the 7 patients had pansinusitis with necrotic destruction of the involved sites and one case revealed colonic lesion. Each of the patients received a tumor dose of $4,000\~5,000 cGy/5\~6$ wks to the upper aerodigestive tract using a 6-MV linear accelerator. Complete and partial remission occured in 3 patients each, and in one case, the disease progressed despite of the irradiation.

A four-year old, indoor-living neutered male Old English Bulldog was presented for generalized ulcerative dermatitis. Generalized alopecia and multifocal papules and ulcers with crusting were observed mainly in the dorsal trunk. Cytology of the skin lesions revealed a pyogranulomatous inflammation comprising macrophages and nondegenerate neutrophils. Histopathology also revealed a nodular dermatitis characterized by mixed infiltration of monocytes and neutrophils involving the superficial and deep dermis. Neither of bacteria nor fungus was identified in microscopic exam and culture. From those findings, a diagnosis of cutaneous sterile pyogranuloma/granuloma syndrome (SPGS) was made. Treatment with immunosuppressive drugs of prednisone and cyclosporine was performed and visible ulcerative skin lesions were resolved after 4 weeks of initiation of therapy. Treatment with combination of cyclosporine and prednisone may be effective for the case of SPGS.

Purpose: The aim of this study was to characterize the cone-beam computed tomographic (CBCT) imaging features of central giant cell granuloma (CGCG) of the jawbone. Materials and Methods: This study retrospectively reviewed 26 CBCT studies of histologically proven cases of CGCG during a period of 20 years, from 1999 to 2019. Patients' demographic data were recorded, and radiographic features were assessed (location, border, cortication, appearance of the internal structure, locularity, septation, expansion, cortical perforation, effects on surrounding tissue, whether the lesion crossed the midline, and lesion volume). Results: In this study, CGCGs were seen almost twice as often in the mandible than in the maxilla, and 64.7% of mandibular lesions involved the anterior region. Only 26.9% of lesions crossed the midline, a feature that was considered characteristic of CGCG. Furthermore, 65.4% of lesions were unilocular and 34.6% were multilocular. The correlation between a lesion's size and its locularity was statistically significant, and larger lesions showed a multilocular appearance. The mean volume of multilocular lesions was greater than that of unilocular lesions. Conclusion: CGCGs showed variable radiographic features on CBCT, and this imaging modality is highly effective at demonstrating the radiographic spectrum and lesional extent of CGCGs in the jawbone.

A two-year-old, intact male, 45 kg Doberman Pinscher was referred with dermal nodular lesions affecting the left hindlimb. The cytological examination revealed eosinophilic inflammation. Skin biopsy specimens showed canine eosinophilic granuloma (CEG). The dog was administered oral prednisolone (1.5 mg/kg/day) and azathioprine (2 mg/kg/day). After one week, the skin lesions diminished dramatically, but the dog presented with severe watery diarrhea. The prednisolone dose was reduced by 0.9 mg/kg/day. The lesions and diarrhea improved markedly after one week. Prednisolone was tapered by 25% of the previous dose every week to 0.2 mg/kg/day. Azathioprine was also reduced to therapy every other day. After seven weeks of combination treatment, the medications were withdrawn, but the dog had a recurrence one week later. Azathioprine (2 mg/kg/EOD) was reintroduced for two weeks. There was no relapse after all the medications had been withdrawn. This case indicates that CEG can be managed with prednisolone and azathioprine. Azathioprine may be an effective adjunctive immunosuppressive agent, and may be considered as a well-tolerated prednisolone sparing agent to treat CEG.

Silicone granulomas are rare, benign lesions that may occur after breast augmentation. Occasionally, a careful differential diagnosis is necessary because lymphadenopathy or malignancy is suspected based on an imaging study. A 56-year-old woman who visited the hospital due to a lung nodule in the left upper lobe (LUL) underwent a staging work-up with the suspicion of lung cancer. Positron emission tomography/computed tomography and chest computed tomography revealed the LUL nodule and a lesion in the left internal mammary chain (IMC), suggesting lymphadenopathy. Diagnostic wedge resection was performed, followed by curative surgery. The final biopsy result confirmed that the LUL nodule was pathologic stage IB adenocarcinoma; unexpectedly, the lesion in the left IMC was a silicone granuloma.
