Esophageal involvement is an extremely rare complication of tuberculosis even in countries with high prevalence of infection. We report the case of a 57 year-old hiv-seronegative patient with simultaneous diagnoses of oral blastomycosis and laryngeal papillomatosis. Both were confirmed by anatomopathological analysis. The esophageal biopsy revealed granulomatous esophagitis with necrosis and zi...

Tuberculosis of the penis is rare. The clinical features of penile tuberculosis are usually manifested as ulceration or scars. However, the authors encountered a case of penile tuberculosis that presented as a mass. A painless nodule at the base of the penis was noted in a 63-year-old male patient. Surgical excision was recommended, and pathologic finding revealed granulomatous inflammation in ...

In this report we present a case of a young lady with abdominal abscesses and septicemia caused by Mycobacterium chelonae complex. Identification of the organism and initiation of the appropriate antimicrobial therapy was delayed, resulting in significant morbidity and multiple hospital admissions. Gram staining of these organisms from blood culture can be easily overlooked or confused with eit...

OBJECTIVE To determine molecular prevalence of Cryptosporidium in a cohort of Egyptian children and compare three diagnostic tests. METHODS Stool samples from children with diarrhea (n=150) and from apparently healthy children (n=100) were examined for Cryptosporidium using microscopy, enzyme linked immuosorbant assay (ELISA) and nested polymerase chain reaction (nPCR). RESULTS nPCR detecte...

Figure 2 Histopathological examination showed inflammatory granulation tissue. Kinyoun stain revealed multiple acid-fast bacilli (arrows). Culture of tissue in L wenstein-Jensen media yielded Mycobacterium tuberculosis. Intestinal tuberculosis should form part of differential diagnosis of patients presenting with lower gastrointestinal bleeding. Figure 1 A 20-year-old man with a complaint of he...

Worldwide, laboratory technicians tediously read sputum smears for tuberculosis (TB) diagnosis. We demonstrate proof of principle of an innovative computational algorithm that successfully recognizes Ziehl-Neelsen (ZN) stained acid-fast bacilli (AFB) in digital images. Automated, multi-stage, color-based Bayesian segmentation identified possible 'TB objects', removed artifacts by shape comparis...

We report a first case of tuberculosis of oral cavity affecting the left alveolus from Nepal in a 63-year-old male who came to otorhinolaryngology outpatient department with a complaint of an ulcer in the oral cavity and pain in bilateral ear and throat. An ulcer measuring 1.8 cm in diameter with irregular friable margin and bleeding on touch was found in the left upper alveolar region of the o...

Primary lid tuberculosis after lid surgery is a very rare condition and is likely caused by the introduction of bacilli through epithelial injury. Secondary infection, due to direct hematogenous spread or contiguous spread from adjacent structures are more common presentations of lid tuberculosis. The authors experienced a case of primary lid tuberculosis occurring in a 19 year old female after...

Sarcoidosis is a granulomatous disease of unclear etiology. Cardiac involvement in sarcoidosis is rarely diagnosed clinically. It is not commonly fatal, but when sarcoidosis is fatal, it is most often from cardiac involvement and when sarcoidosis involves the heart, it frequently causes death. We report a case of sudden death of 48 years male, wherein sarcoidosis with cardiac involvement was di...
