In order to emphasise the importance of histopathology in the clinically unsuspected diagnosis of duodenal strongyloidiasis, we report six cases diagnosed on duodenal biopsies identified from the database over a period of 15 years, and clinical, endoscopic and histopathological findings were analysed retrospectively. Four were elderly males and the remainder young females. Only one patient had an underlying immunocompromised state. Three presented with cholestatic jaundice and simulated hepatobiliary malignancy. In all cases, endoscopy provided non-specific findings. Only one case showed a predominant eosinophilic infiltrate. Eggs, larvae and adult forms of strongyloides were seen in crypts and showed intense basophilic staining on HE stain. It is concluded that since mostly undetected clinically, duodenal biopsy serves as the first step in the diagnosis of strongyloidiasis. Hepatobiliary manifestations, though very infrequent, should raise the suspicion for strongyloidiasis and thus necessitate the need for duodenal biopsy.

Rosai-Dorfman disease (RDD) is characterized histologically by a dense histiocytic infiltrate with emperipolesis and associated lymphocytes, plasma cells, and neutrophils. Eosinophils are not commonly associated. We report a patient with initial thymus and pituitary gland involvement by RDD, who later developed papules on the groin and axilla. Skin biopsies showed admixed histiocytic infiltrates (lymphocytes, neutrophils, and plasma cells) without emperipolesis. A prominent eosinophilic infiltrate was also observed, a feature not, to our knowledge, previously reported. Immunohistochemistry revealed positivity for CD68 (most cells) and S100 protein (scattered cells) and was negative for anti-CD1a. The diagnosis of RDD was established in the clinical context after comparison with the thymic and pituitary lesions (similar histologic features, albeit with fewer eosinophils, and immunohistochemical profiles). We present the first case, to our knowledge, of multicentric RDD with cutaneous involvement and associated prominent eosinophilic infiltrate. Thus, RDD should be included in the differential diagnosis of mononuclear infiltrates containing eosinophils.

Aba VitėnasVšĮ Vilniaus universiteto ligoninės "Santariškių klinikos"Centro filialas, Radiologijos skyrius,Žygimantų g. 3, LT–01102, VilniusEl. paštas [email protected] Įvadas / tikslas Plaučių disontogeniniai navikai – hamartomos – yra dažniausi iš visų periferinių nepiktybinių rutulinių plaučių darinių. Endobronchinė centrinė hamartoma (epistoma) pasitaiko labai retai. Kremzlinės struktūros plaučių hamartomos – chondrohamartomos ir osteochondrohamartomos – yra dažniausios. Darbo tikslas – apibūdinti plaučių hamartomas, sukonkretinti jų rentgenologinius diferencinės diagnostikos žymenis ir tuo remiantis – klasifikaciją. Ligoniai ir metodai Plaučių hamartomos buvo nustatytos 43 ligoniams – 16–78 metų 28 vyrams ir 15 moterų. Visiems ligoniams atliktas kompleksinis radiologinis tyrimas – polipozicinė rentgenoskopija, rentgenografija, tomografija, skaitmeninė fluorografija, kompiuterinė tomografija. Bronchoskopija ir biopsija padaryta 31 ligoniui. Buvo atliekami ir kiti tyrimai: ultragarsinis, funkciniai plaučių mėginiai, specifinės laboratorinės reakcijos diferencinei diagnostikai nuo plaučių tuberkuliozės, kolagenozės, echinokokozės, alergozės. Rezultatai 42 ligoniams diagnozuota periferinė ir vienam – centrinė hamartoma. Tipinė plaučių hamartomos lokalizacija – dešiniojo plaučio apatinė skiltis (21 ligonis, arba 49%). Centrinė endobronchinė hamartoma diagnozuota 42 metų ligoniui, ilgai sirgusiam lėtiniu bronchitu ir dažnai plaučių uždegimu. Operuota 30 ligonių. Devyni ligoniai iš 13 neoperuotųjų stebėti nuo 1 iki 14 metų. Periferinės hamartomos dažniausiai buvo besimptomės. 23 ligoniams hamartoma nustatyta atsitiktinai profilaktiškai tiriant plaučius dėl įvairių pilvo organų ligų arba atliekant fluorografinį tyrimą. Kitiems tirtiesiems hamartoma buvo diagnozuota sergant plaučių ligomis, tuberkulioze, alergoze, kolagenoze, įvairiais navikais. Dvylikai ligonių nepiktybinio plaučių naviko, arba hamartomos, diagnozė buvo tiksliai nustatyta poliklinikoje. Devyniems buvo įtartas pirminis vėžys arba metastazė, šešiems – specifinis infiltratas arba tuberkuloma, vienam – eozinofilinis infiltratas, vienam – echinokokas. Hamartoma 31 ligoniui buvo dešiniajame, 12 – kairiajame plautyje. Rentgenogramoje periferinė hamartoma buvo matoma apskritos formos ir ryškių kontūrų. Jos rentgenologinė struktūra buvo nevienoda. Šviesi (nekalcifikuota) hamartoma buvo matoma 14 ligonių. Kitiems 28 ligoniams diagnozuota kalcifikuota (inkrustuota arba tamsi) hamartoma, t. y. hamartochondroma (chondrohamartoma, osteochondrohamartoma). Išvados Nors plaučių hamartomos auga labai lėtai, pasitaiko labai greitai progresuojančių: 3 ligoniams, arba 7%, hamartomos per metus padidėjo iki 50%. Dažniausias jų variantas – hamartochondroma (chondrohamartoma). Piktybinių hamartomų nediagnozuota. Pagal neoplazinės kalcinozės laipsnį plaučių hamartomos radiologiškai skirstomos į tris variantus: šviesas, inkrustuotas ir tamsias. Radiologai gali diferencijuoti dažniausius plaučių hamartomų variantus, tarp jų chondrohamartomas ir osteochondrohamartomas. Reikšminiai žodžiai: disontogeniniai plaučių navikai, disembriomos, periferiniai plaučių navikai, hamartomos, hamartochondromos, neoplazinė kalcinozė, rentgenodiagnostika Diagnostics of pulmonary chondrohamartomas Aba Vitėnas Background / objective Hamartomas, as dysontogenic tumours, are most common among all peripheral non-malignant "spheral" pulmonary formations. Endobronchial central hamartoma is rare and is usually diagnosed as "epystoma" (bronchial obturator). Among peripheral hamartomas, tumours of cartilaginous structure (chondrohamartomas and ostheochondrohamartomas) are particularly common. The objective of the work was to describe pulmonary hamartomas and to concretize most common variations of hamartoma and their different radiological signs. Patients and methods Forty-three patients were diagnosed with pulmonary hamartoma (28 males and 15 females, 16–78 years old). In the hospital, clinical and laboratory tests were performed for all patients; complex radiological examination: polypositional X-ray radioscopy, radiography, tomography, digital fluorography, computed tomography. Thirty-one patients underwent bronchoscopy and biopsy, sonoscopy, functional lung tests, specific reactions. Results Forty-two patients had peripheral and one central hamartoma. The most typical localization of pulmonary hamartoma was the lower lobe of the right lung (21 patients, 49%). A central endobronchial hamartoma was diagnosed for a 42-year-old patient who had been ill for a long time with chronic bronchitis and frequent pneumonias. 30 pacients were operated one. From 13 non-operated patients, 9 were followed up in dynamics for 1–14 years. Peripheral hamartoma usually was asymptomatic. Twenty-three patients were diagnosed occasionaly during preventive pulmonary evaluation in case of different abdominal diseases or during fluorography. The others diagnosed as having hamartoma were ill with lung diseases, TBC, alergosis, collagenosis, different tumours. In out-patient settings, correct diagnosis of benign tumour or hamartoma was established for 12 patients, 9 were suspected as having cancer or metastases, 6 – specific infiltrate (tuberculoma), 1 – eosinophilic infiltrate and 1 – echinococcus; 31 patient had the tumour in the right, and 12 patients in the left lung. Radiologically, hamartoma is a spheric tumour with clear margins. As to the structure of the tumour, 14 patients had non-calcificated, "light" hamartoma, 28 had calcificated, "inlaid" and "hard" hamartochondroma. Thus, neoplastic calcinosis is characteristic of chondrohamartomas (osteochondrohamartomas) and occurs twice as often as hamartomas of other types. Conclusions Althought hamartomas grow very slowly, there were rapidly increasing ones: for 3 patients (7%) the volume of hamartoma increased by 50% in a year. The most common type was hamartochondroma (chondrohamartoma). There were no malignant hamartomas. Therefore radiologists can diagnose most common variations of hamartomas as "light", "inlaid" and "hard" ones.

Gingival pathology is a daily presentation, however a small number of systemic conditions can manifest similar to a common gingival condition and have fatal results. Dentist referred 56-year-old woman to Oral and Maxillofacial Surgery department with a 2-week medical history of gingival bleeding not responding to local measures. Biopsy showed eosinophilic infiltrate and vasculitis, and blood tests showed positive markers including cytoplasmic antineutrophil cytoplasmatic antibodies. Granulomatosis with polyangiitis is a rare disease affecting the respiratory tract, blood vessels and kidneys. Oral lesions are rarely the primary presenting feature. When left untreated, most cases are fatal within a year of diagnosis. The diagnosis can only be made when certain criteria are found, including granular oral lesions exhibiting an eosinophilic inflammatory infiltrate on biopsy. With 5% of cases showing intraoral lesions as the primary feature, it is essential that dentists have the knowledge of this rare disease to refer and not to treat as a common gingival condition.

ABSTRACT BACKGROUND: The role of Helicobacter pylori infection on eosinophilic infiltration in duodenal mucosa is poorly studied. An increase in the number of eosinophils in duodenum has been associated with functional dyspepsia. OBJECTIVE: To evaluate the influence of H. pylori infection on duodenal eosinophil count and the role of eosinophilic infiltrate of duodenum in functional dyspepsia. METHODS: Positive and negative H. pylori individuals were included. Both functional dyspeptic patients according to Rome III criteria (cases) and individuals without gastrointestinal symptoms (controls) were enrolled. They were submitted to upper endoscopy and H. pylori infection was verified by gastric histopathology and urease test. Eosinophils in the duodenal mucosa were counted in five high-power fields, randomly selected on slides of endoscopic biopsies. RESULTS: Thirty-nine H. pylori positive (mean age 40.5 and 69.2% women) and 24 negative patients (mean age 37.3 and 75% women) were included. The influence of the infection was observed in the duodenal eosinophil count, which was higher in infected individuals: median 13.2 vs 8.1 in non-infected individuals (P=0.005). When we analyzed patients according to symptoms, cases - mean age 39.6; 71.4% women - and controls - mean age 38.7; 71.4% women - had similar duodenal eosinophil count: median 11.9 and 12.6 respectively (P=0.19). CONCLUSIONS: We did not demonstrate association of duodenal eosinophil count with functional dyspepsia but found association with H. pylori infection.
