Idiopathic granulomatous mastitis. Report of a case diagnosed with fine needle aspiration cytology.

BACKGROUND: Idiopathic granulomatous mastitis (IGM) is a benign, inflammatory breast disease of unknown etiology. Although it is rare, it frequently presents in a manner similar to that of breast carcinoma. CASE: A 41-year-old female developed unilateral idiopathic granulomatous mastitis, diagnosed by fine needle aspiration cytology. The clinical presentation and mammographic findings were suspicious for carcinoma. Fine needle aspiration cytology showed granulomatous inflammation. Histopathologic examination revealed a noncaseating, granulomatous lesion. Further clinical, radiologic and laboratory investigations disclosed no etiology. Therefore, we considered the case to be idiopathic granulomatous mastitis. CONCLUSION: Cytologically it may be difficult to distinguish IGM from carcinoma of the breast. Typical cytologic findings of the lesion are helpful to rule out cancer. In the differential diagnosis, all known causes of granulomatous changes have to be excluded before a diagnosis of idiopathic granulomatous mastitis is made.

Imprint cytology in the diagnosis of Helicobacter pylori. Does imprinting damage the biopsy specimen?

OBJECTIVE: To investigate the efficacy of imprint cytology in the diagnosis of Helicobacter pylori infection and whether it damages the biopsy specimen for subsequent histologic examination. STUDY DESIGN: Two antral biopsies were taken from 76 patients with dyspeptic symptoms undergoing upper gastrointestinal endoscopy. Imprint cytology was made from the first specimen. This specimen was fixed in 10% formalin and sent for histopathologic examination. The second specimen was directly fixed in 10% formalin for routine histopathologic examination without being used for an imprint. The imprint smears were examined by cytopathologists. The biopsy specimens were examined by pathologists who did not know which specimens were used for the imprints. RESULTS: H pylori was seen in smears from 55 (72%) patients and in both biopsy specimens from the same patients. The pathologists could not recognize the biopsy specimens from which the imprints were made. Concordance between imprint cytology and histopathology was 100%. CONCLUSION: Imprint cytology is a suitable test for H pylori diagnosis, and imprints do not adversely affect the quality of the biopsy specimen.

Inhaled corticosteroids may reduce neutrophilic inflammation in patients with stable chronic obstructive pulmonary disease.

BACKGROUND: Although both inhaled and oral corticosteroids have anti-inflammatory effects causing improvement in clinical symptoms and spirometry in the treatment of asthma, the role of corticosteroids in the management of chronic obstructive pulmonary disease (COPD) is controversial. OBJECTIVE: To evaluate the effects of inhaled corticosteroids on sputum neutrophilia in clinically stable COPD patients. METHODS: In total, 18 patients were enrolled in the study. During 2 months, 9 patients in group A inhaled fluticasone propionate (FP) 500 microg 3 times daily. In group B 9 patients received placebo. All of the patients continued to inhale both salbutamol and ipratropium bromide. In 9 patients, sustained-released theophylline was also administered. Blood samples, spirometric tests, blood gas analyses, and either spontaneous or induced sputum cultures were evaluated on entry into the study, after a 2 months of treatment and following the 6-week washout period. RESULTS: After the 2-month FP treatment, no significant changes in the number of peripheral blood neutrophils, blood gas and spirometry data were observed in both groups. In group A, the total cell number and the number of neutrophils decreased from a mean of 3. 4 +/- 1.3 x 10(6) cells/g and 0.6 +/- 0.3 x 10(6) neutrophils/g on entry into study to 1.9 +/- 0.6 x 10(6) cells/g and 0.02 +/- 0.01 x 10(6) neutrophils/g after 8-week treatment with FP, returning to 3.3 +/- 1.1 x 10(6) cells/g and 0.5 +/- 0.3 x 10(6) neutrophils/g following the washout period. The percentages of neutrophils were 55. 6 and 77.9% in groups A and B after 2 months of FP treatment. There was no significant change in group B values during the study. CONCLUSION: These data suggest that neutrophilic inflammation in sputum may be decreased by inhaled corticosteroids in clinically stable COPD patients.
