    ABSTRACT: We report three cases of hyper-IgG4 disease with synchronous or asynchronous lymphocytic infiltration onset, IgG4 positive plasma cell infiltration, and fibril formation in multiple exocrine glands and extranodal organs. IgG4-related sialadenitis attracting recent attention has yet to be clarified as a clinical entity. Case 1, a 61-year-old man, had a submandibular gland sample showing IgG4-positive plasma cell infiltration. Case 2, a 61-year-old man, was diagnosed with IgG4-related Mikulicz's disease confirmed by a sublingual gland sample. Case 3, a 57-year-old woman, had a diagnosis of IgG4-related Mikulicz's disease confirmed based on labial and sublingual gland samples. All reported oral dryness and bilateral submandibular swelling. Cases 1 and 2 recovered following Predonine administration tapered from 30 or 20 mg. IgG4-related Mikulicz's disease must be recognized as a clinical entity, together with its diagnostic criteria and treatment. Sublingual gland biopsy should be done to confirm its diagnosis following sublingual gland swelling.

    ABSTRACT: The nasal valve area has long been under investigation and has been measured with various methods with varying modifications. This diversity in methodology points to two aspects, namely, the definition itself is vague and the morphological configuration is rather complicated for refined evaluations. We investigated and evaluated the area using coronal CT scans on 133 subjects.

    ABSTRACT: The different modalities of malignant tumor invasion were presented and discussed. When determining the extent of malignant tumor invasion, it is useful to assess surrounding tissues such as bone marrow, fat tissues, and nerves.In addition, qualitative diagnoses can be made based on such information as the location of bony destruction as well as the preservation of maxillary sinus mucosa. We reviewed diseases having characteristic magnetic resonance imaging (MRI) findings.These findings are useful for distinguishing between malignant and benign lesions that occur in the nasal and paranasal sinuses.

    ABSTRACT: The nasal valve was studied using coronal scans by computed tomography (CT). Coronal images were 5 mm thick obtained from 133 subjects 93 men and 40 women averaging 46 years of age. The valvular area was studied in 2 slices containing nasal valve, anterior and posterior slices 5 mm apart. After defining standard points for evaluation, breadth, height and area were evaluated using NIH Image Version 1.59 from left and right as an unit. Results were follows: 1. The breadth of the nasal valvular area is larger in men than in women, and the height greater. The angle of valvular area is similar in both. 2. A comparison of anterior and posterior slices showed the smallest breadth of valvular area in the anterior slice to be smaller than in the posterior slice. The breadth of the vestivular area below the valvular area is larger in the anterior than posterior slice. The angle in the anterior slice is larger than that in the posterior slice. The area of valvular area in the anterior slice is smaller than that in the posterior slice.
