Actinomycosis is a rare, chronic, and slowly progressive granulomatous disease caused by filamentous Gram posi­ tive anaerobic bacteria from the Actinomycetaceae family (genus Actinomyces). It is often misdiagnosed because it can mimic other conditions such as malignancy and tuber­ culosis, and a high level of clinical suspicion is needed for an early diagnosis. However, it is readily treatable...

Actinomycosis is a slowly progressive chronic granulomatous bacterial infection caused by an anaerobic gram-positive bacillus: Actinomyces Israeli.Thinking about thisdiagnosis in the right iliac fossa uncommonas it usually shows through clinical aspect of acute appendicitis, Crohns disease or even tumor ileocolic region. We report case young female patient admitted for pain and palpable mass, m...

Actinomycosis is a rare anaerobic, gram-positive bacterial infection caused by Actinomyces. As an site for the disease, cervicofacial area common but nasal cavity and nasopharynx are rare. causes chronic purulent granulomatous characterized extensive infiltration, necrosis, bone destruction on CT. Extranodal natural killer/T cell (NK/T cell) lymphoma, type more in East Asia than elsewhere, comp...

pediatric cervicofacial actinomycosis is a rare occurrence consequent to dental infections and manipulations or maxillofacial trauma. the clinical presentation ranges from multiple draining sinuses to swellings resembling tumors and cysts. the present unusual case had congenital dermoid cyst of mid upper lip with actinomyces israelii infection identified on microscopy, culture, and histopatholo...

Herein, we reported on a case of solid type of pulmonary actinomycosis in a 10-year-old boy. He had productive cough for 40 days. Bronchoscopy was normal. Cmputed tomography revealed a solid large mass in the upper lobe of his left lung with mimicking malignant leisions. He was referred for surgery and underwent left upper lobectomy. Macroscopically, the specimen measured 13×9×5 cm and was crea...

Actinomycosis is an infrequent chronic infection regarded as the most misdiagnosed disease by experienced clinicians. The Office of Rare Diseases at the National Institute of Health has also listed this disease as a "rare disease." This article presents a case report of actinomycosis of the alveolus with unusual clinical features but a successful resolution. It also states the importance of bio...

Thoracic actinomycosis is a rare disease in children. Diagnosis is typically delayed, since the presentation can be very similar to that of malignant tumors, tuberculosis, and fungal infections. We here present the case of a 9-year-old girl who was treated for tuberculosis at the first presentation, for non-Hodgkin's lymphoma at the second presentation, and for chronic granulomatous disease at ...

later is associated with necrosis of skin and subcutaneous tissue leading to eschar formation. Other gradually progressive diseases presenting as discharging sin-uses in children are actinomycosis, botryomycosis, nocardiosis, and sporotrichosis. Sinus tracts of actinomycosis and nocardiosis usually discharge granules; botryomycosis is associated with subcuta-neous nodules and large verrucous (w...

Xanthogranulomatous gastritis (XGG) is a rarely encountered condition, and its causative mechanism is still unclear. Given that some types of xanthogranulomatous inflammation (XGI) are associated with pathogens, infection should be considered as a possible cause of XGG. Herein, we report a case of an 86-year-old woman presenting with a large, bleeding lesion resembling a submucosal tumor. Dista...
