An otherwise healthy 29-year-old Indonesian man presented with a 6-month history of low back pain and right buttock swelling, with radiating pain into the right leg. The pertinent laboratory results were as follows: WBC 12,000/ μL, C-reactive protein 9.08 mg/dL, a normal urinalysis, and a negative human immunodeficiency virus test. Computed tomography (CT) revealed an expansile low density mass...

BACKGROUND Cellulitis caused by Mycobacterium avium-intracellulare has rarely been described. Mycobacterium avium-intracellulare is a rare cause of septic arthritis after intra-articular injection, though the causative role of injection is difficult to ascertain in such cases. CASE PRESENTATION A 57-year-old with rheumatoid arthritis treated with prednisone and azathioprine developed bilatera...

Epithelial-myoepithelial carcinomas are rare tumors that primarily originate in the salivary glands but have also been found in the tracheobronchial tree. We report the first case of epithelial-myoepithelial carcinoma associated with sarcoidosis. A 61 year old Hispanic man presented with altered mental status and hypercalcemia. Imaging revealed diffuse intra-thoracic and intra-abdominal lymphad...

Abdominal tuberculosis (TB) is the sixth most common location of extrapulmonary TB involvement. Because its symptoms and signs are often nonspecific, laboratory and imaging findings mimic other diseases including carcinoma. Therefore, the diagnosis of abdominal TB is challenging. We herein report a case of 74-year-old woman who presented with abdominal pain, anorexia, and weight loss. She had b...

BACKGROUND Tuberculosis and sarcoidosis are chronic diseases that rarely occur concomitantly. Sarcoidosis is a multisystem granulomatous disorder characterized pathologically by the presence of non-caseating granulomas in involved tissues. Tuberculosis is infectious disease caused by Mycobacterium tuberculosis characterized by granulomas with caseous necrosis. CASE PRESENTATION We present a c...

Clear cell hepatocellular carcinoma (CCHCC) is a rare variant of classical hepatocellular carcinoma (CHCC). Most of these cases pose a histological diagnostic dilemma with broad range of differentials of tumor with clear cell morphology. Use of immunostains or presence of classical hepatocellular carcinoma morphology focally aids in accurate diagnosis of these lesions. We report a case of a 62-...

This case demonstrates two unusual characteristics of acute histoplasmosis. One is the finding of endobronchial periadenitis ofthe involved adjacent lymph nodes. Typically, the appearance of the endobronchial anatomy in pulmonary histoplasmosis offers little diagnostic value. More than 90 percent of patients undergoing bronchoscopy during the course of acute histoplasmosis have a normal bronchi...

Background: Tuberculosis (TB) is a health problem worldwide. Cutaneous TB comprises a small fraction of all clinical forms of TB. Objective: The purpose of this study was to assess the disease pattern of cutaneous TB in an Asian country. Materials and Methods: Totally, 50 cases of cutaneous TB were diagnosed on histopathology in a tertiary care hospital over a period of 7 years. Relevant clinic...
