A button battery inserted in the nose of children is an unusual foreign body which is capable of causing extensive tissue damage, resulting from electrical and chemical burns. We report a case of button battery in the nose of a 4-year-old boy presenting with unilateral nasal discharge, and necrosis in the septum and turbinate of the right nasal cavity. Mercury level in concentrated urine was within normal limit. Microscopic examination disclosed extensive liquefaction necrosis with calcification and fibrosis. Numerous dark brown to black granules were noted in the elastic and collagen fibers and interstitium. Dark-field examination of the section revealed brilliantly refractile granules. Polarized microscopy failed to show the granules. Most brown pigments reacted to prussian blue. Tissue mercury analysis yielded a mercury content of 8.01 ppm. We report this case to emphasize the hazards of button battery impaction and to draw attention to the significance of the problem through histopathologic examination.

OBJECTIVE: To study the clinicopathologic features, immunophenotype, diagnosis and differential diagnosis of Sinonasal teratocarcinosarcoma (SNTCS). METHOD: The clinical findings, morphologic features and immunohistochemical markers in one case of SNTCS were studied, and the relevant literatures were reviewed. RESULT: The Tumor tissue is composed of three layers, with mature and immature squamous epithelium nests, neural epithelial cells and olfactory neuroblastoma-like cells derived of ectoderm; Sarcomatoid components and bone tissue derived of mesoderm; The glandular and tubular structures part of which is adenocarcinoma and respiratory epithelium derived of endoderm; The fetal clear cell squamous epithelium is typical. In addition, diffuse large cytoplasm-with high light and cytoplasm with dark light has no obviously boundery. Immunohistochemical staining showed immune markers of different germ layers corresponding, squamous epithelium, glandular epithelium and respiratory epithelium were positive for CK and EMA, neural epithelial cells and olfactory neuroblastoma-like cells were positive for S-100, NSE and Syn, sarcomatoid area was positive for Vim, light dye area was positive for Vim, CD99 and CK, dark area was positive for NSE and GFAP. CONCLUSION SNTCS is a rare malignant tumor with the features of teratoma and carcinosarcoma, its histopathological and immunohistochemical features were typical, should be more drawn and sliced to avoid misdiagnosis and missed diagnosis.

OBJECTIVETo study the prevalence of IgG4-positive plasma cells in inflammatory disease of nasal cavity and paranasal sinuses and its association with IgG4-related sclerosing disease (IgG4-SD).

METHODSThe expression of IgG4 and IgG in plasma cells of 103 cases diagnosed as inflammatory disease of nasal cavity and paranasal sinuses with dense lymphoplasmacytic infiltrate was studied by immunohistochemistry (EnVision) and quantitatively analyzed by medical image analysis system.

RESULTSImmunohistochemical study showed marked infiltration by IgG4-positive plasma cells (>50 per high-power field) in 28 cases, moderate infiltration (30 to 50 per high-power field) in 23 cases, mild (10 to 29 per high-power field) in 30 cases and negative (<10 per high-power field) in 22 cases (P < 0.05). Twenty-two cases studied fulfilled the diagnostic criteria of IgG4-SD (>50 IgG4-positive plasma cells per high-power field and IgG4-to-IgG ratio > 40%), including 3 cases of chronic sinusitis (3/20), 3 cases of nasal polyps (3/18), 3 cases of inflammatory pseudotumor (3/17), 4 cases of fungal sinusitis (4/20), 1 case of rhinoscleroma (1/12), 7 cases of Wegener's granulomatosis (7/11) and 1 case of Rosai-Dorfman disease (1/2).

CONCLUSIONInflammatory disease of nasal cavity and paranasal sinuses fulfilling the diagnostic criteria IgG4-SD is not uncommon. Definitive diagnosis of IgG4-SD requires correlation with other clinical and laboratory findings. Some cases of unexplained inflammatory disease of nasal cavity and paranasal sinus may represent a member of the IgG4-SD spectrum. IgG4 carries diagnostic value in differential diagnosis of inflammatory disease occurring in nasal cavity and paranasal sinuses.

BACKGROUND: Burn wounds lack normal barriers that protect against pathogenic bacteria, and burn patients are easily colonized and infected by Staphylococcus aureus. Toxic shock syndrome (TSS) is a rare but fatal disease caused by S. aureus. A lack of detectable antibodies to TSS toxin-1 (TSST-1) in serum indicates susceptibility to TSS. METHODS: A total of 207 patients (169 men and 38 women; median age, 42.5 yr) admitted to a burn center in Korea were enrolled in this study. The serum antibody titer to TSST-1 was measured by sandwich ELISA. S. aureus isolates from the patients' nasal swab culture were tested for TSST-1 toxin production by PCR-based detection of the TSST-1 toxin gene. RESULTS: One hundred seventy-four (84.1%) patients showed positive results for antibody against TSST-1. All patients aged > or =61 yr (n=28) and <26 months (n=7) were positive for the anti-TSST-1 antibody. S. aureus was isolated from 70 patients (33.8%), and 58.6% of the isolates were methicillin resistant. Seventeen patients were colonized with TSST-1-producing S. aureus. The antibody positivity in these 17 carriers was 88.2%, and the positivity in the non-carriers was 83.7%. CONCLUSIONS: Most burn patients had antibody to TSST-1, and nasal colonization with TSST-1-producing S. aureus was associated with positive titers of anti-TSST-1 antibody. Additionally, patients with negative titers of anti-TSST-1 antibody might be susceptible to TSS.
