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...

We report a rare case of lung abscess due to Eubacterium brachy. In this case, an analysis of the aspirate from frank pus revealed Gram-positive coccobacilli. We initially strongly suspected lung abscess associated with actinomycosis because of the chronic/recurrent clinical course and radio-pathological findings such as a granuloma lesion. Although a biochemical analysis revealed Actinomyces s...

Actinomycosis is an infection caused by the actinomyces genus and is associated with trauma or previous infection. A 58-year-old male patient was referred from a private dental clinic for root extraction of the lower right molar. The x-ray showed fractured root-like material distal to the distal root of the lower right second molar. A biopsy during extraction of the root-like material was perfo...

Actinomycosis is a subacute or chronic suppurative bacterial infection caused by filamentous gram positive, anaerobic to microaerophilic non acid fast bacilli primarily of the genus Actinomyces that normally colonize the mouth, colon and vagina. Primary cutaneous actinomycosis is a rare entity and is generally associated with trauma. We report a case of primary cutaneous actinomycosis of the ba...

Laryngeal carcinoma and laryngeal papilloma are the most commonly encountered tumorous lesions in the larynx. Herein, we report a case of the mass arising from the left vocal cord in a 49-year-old Japanese man. Endoscopic examination suggested that the mass is a tumor such as carcinoma and papilloma. Pathological examination showed that the specimen demonstrated actinomycosis in the left vocal ...
