1/16. False diagnosis caused by Warthin tumor of the parotid gland combined with actinomycosis.A case is reported in which a unilateral parotid gland cystadenolymphoma was combined with actinomycosis. A 48-year-old woman presented with a mass in the left parotid region and paresis of the lower left palpebra. The computed tomography, echography, and parotid radiographic findings did not exclude a neoplasm of the left parotid gland. The ramus of the mandible was involved in the process. Intraoperative freezing histology, total parotidectomy, and partial mandibulectomy were performed, with sacrifice of the facial nerve followed by nerve reconstruction. The final histological evaluation was Warthin tumor with actinomycosis. Four years after treatment, the patient is free of disease. No similar cases seem to have been reported thus far.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/16. actinomycosis abscess of the thyroid gland.OBJECTIVES: To present an unusual case of actinomycosis abscess of the thyroid gland as well as review the history, etiology, pathogenicity and treatment of actinomycosis infections of the head and neck. STUDY DESIGN: Case study. methods: A report of a 39 year-old female status post tooth extraction that developed an actinomycosis abscess of the thyroid. RESULTS: After a thyroid actinomycosis abscess was suggested by physical exam, ultrasound, CT scan and needle aspiration, an otolaryngology consult was obtained. The patient successfully was managed with thyroidectomy and intravenous ceftriaxone. CONCLUSIONS: Although actinomycosis soft tissue infections of the head and neck are relatively uncommon, the head and neck surgeon must include it in the differential diagnosis when clinical presentation raises suspicion. Early biopsy is necessary for appropriate identification of the organism with the appearance of sulfur granules lending a clue to the diagnosis. debridement and/or excision are often necessary for antibiotics to be used successfully. Antimicrobial therapy should be used for six to twelve months to completely eradicate the disease and prevent recurrence.- - - - - - - - - - ranking = 0.83333333333333keywords = gland (Clic here for more details about this article) |
3/16. Oral metastasis of breast carcinoma diagnosed by fine needle aspiration cytology. A case report.BACKGROUND: Fine needle aspiration cytology (FNAC) is an important technique in the diagnosis of oral and maxillofacial conditions. The purpose of the present paper is to report a case of oral metastasis of breast carcinoma diagnosed by FNAC. CASE: A 45-year-old, black woman was referred for evaluation of symptomatic swelling in the left mandible. The medical history revealed that the patient had undergone extensive surgery to remove a lobular carcinoma. She had finished chemotherapy treatment about 5 months earlier. Due to the main diagnostic considerations of metastatic and inflammatory disease, FNAC was performed. The cytologic picture was consistent with a metastatic glandular neoplasm. CONCLUSION: FNAC is a safe, reliable, cost-effective and easy procedure and sometimes eliminates the need for open biopsy.- - - - - - - - - - ranking = 0.16666666666667keywords = gland (Clic here for more details about this article) |
4/16. actinomycosis of the parotid masquerading as malignant neoplasm.BACKGROUND: Primary actinomycosis of the parotid gland is of rare occurrence and can mimic a malignant neoplasm both clinically as well as radiologically. CASE PRESENTATION: We present here a case of primary actinomycosis of the parotid gland presenting with a parotid mass lesion with erosion of skull bones. CONCLUSIONS: Clinical presentation of cervico-facial actinomycosis is characterized by the presence of a suppurative or indurative mass with discharging sinuses. The lesion demonstrates characteristic features on fine needle aspiration cytology and histology, however at times the findings are equivocal.- - - - - - - - - - ranking = 0.33333333333333keywords = gland (Clic here for more details about this article) |
5/16. actinomycosis of submandibular gland: an unusual presentation.An unusual presentation of oro-facial actinomycosis, mimicking the clinical appearance of a malignant lesion is reported. The patient, a 74-year-old female, presented with a right submandibular mass, which slowly grew in size over a period of about 2 months, and a modest dysphagia. A painless cervical mass was palpable over the submandibular region. The rhino-pharyngo-laryngeal region, explored by flexible fiberoptic examination, was normal. At ultrasonography, a 2x2 cm infiltrating dyshomogeneous mass, involving the right submandibular gland, was visible. No connection with adjacent organs was found. There was no associated cervical lymphoadenopathy. Ultrasound-guided fine-needle aspiration cytology, performed on lesion, revealed no evidence of malignancy. The presence of characteristic colonies of actinomyces infection was found. The patient was treated initially with tetracycline chloridrate 100 mg: 1 tablet every 12 hours for 7 weeks, but a repeat ultrasonography showed no resolution. A further fine-needle aspiration cytology showed no actinomyces infection in the specimen. The patient was treated with methylprednisolone, 20 mg every 24 hours, for 5 days. After steroid treatment, the patient has been well and, upon repeat ultrasonography, total resolution of the submandibular lesion was confirmed. In conclusion, the clinical presentation of cervicofacial actinomycosis is variable and may mimic a malignant lesion or chronic granulomatous infections. Diagnostic and therapeutic findings are discussed.- - - - - - - - - - ranking = 0.83333333333333keywords = gland (Clic here for more details about this article) |
6/16. actinomycosis in neck glands.A middle aged woman presented with right submandibular swelling, fever off and on and anemia. Excisional biopsy of the gland showed actinomycosis. It is a rare disease in the neck. Patient was treated with high doses of parenteral pencillins followed by three months course of oral Doxycyclines. The patient was followed up to six months and she was symptom free. In this case report the disease is elaborated and literature is reviewed.- - - - - - - - - - ranking = 0.83333333333333keywords = gland (Clic here for more details about this article) |
7/16. actinomycosis of the middle turbinate: an unusual cause of nasal obstruction.actinomycosis is a rare chronic infectious disease caused by actinomyces israelii, which is an anaerobic filamentous, gram-positive saprophyte organism of the oral cavity. Historically, these bacteria were known as fungi because of their light microscopic appearance. actinomycosis consists of three different forms: cervico-facial (the most common form), abdominal and pulmonothoracic. It commonly involves the head and neck region including the mandible, paranasal sinuses, lacrimal gland, parotid gland and orbit. Poor oral hygiene and dental diseases have been known to be the source of actinomycosis. actinomycosis is diagnosed with positive culture or detecting actinomyces colonies and sulfur granules in histopathologic specimens. The treatment of choice is surgical excision of the lesion and long-term penicillin therapy. actinomycosis of the internal nose is extremely rare. There was only one nasal septum actinomycosis reported in the English literature, but there was no lateral nasal wall actiomycosis regarding the turbinate. Therefore, actinomycosis should not be overlooked for the differential diagnosis of intra-nasal lesions for the initiation of appropriate and early treatment.- - - - - - - - - - ranking = 0.33333333333333keywords = gland (Clic here for more details about this article) |
8/16. Actinomycotic abscess of the thyroid gland in an infant.Actinomycotic abscess of the thyroid gland is rare especially in childhood. In this article, we report the second pediatric case in literature, at age of 18 months. Although spread of actinomycotic infection to the thyroid gland from upper aerodigestive tract by preformed pathways such as piriform sinus fistula seems rational, it was demonstrated neither in current nor in previous cases. Therefore, further work-up such as barium swallow, which is onerous to perform in a child may be reserved for recurrent cases.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
9/16. Perianal actinomycosis: diagnostic and management considerations: a review of six cases.INTRODUCTION: Primary anal actinomycosis of cryptoglandular origin, mainly due to actinomyces israelii, a specific and rare cause of anal suppurative disease, needs to be recognized because it can be cured using specific treatments. METHOD: Data were reviewed from 6 patients with actinomycotic anal abscesses of obvious cryptoglandular origin observed in a single proctology unit between 1983 and 2000. Therapeutic management included conventional surgical treatment of anal sepsis followed by a specific oral antibiotic therapy maintained until the surgical wound had completely healed. RESULTS: All but one of the patients were men (median age, 53 years). All abscesses, except one, were indolent. No patient presented macroscopic "sulphur granules" in the pus, but one presented "watery pus". The diagnosis was established by histological study of the surgically excised tissue or by anaerobic culture of the pus. In the one hiv-positive patient, an uncommon organism was isolated: actinomyces meyeri. Two cases of recurrence were observed without evidence of actinomyces infection. CONCLUSION: actinomycosis should be suspected particularly in indolent anal suppuration. The absence of macroscopic "sulphur granules" does not mean this diagnosis can be ruled out. Careful histological examination of the excised tissue and appropriate anaerobic cultures of pus should be carried out to achieve complete eradication of this rare, but easily curable disease.- - - - - - - - - - ranking = 0.33333333333333keywords = gland (Clic here for more details about this article) |
10/16. Unusual parotid tumors.The patient presenting with a mass lesion of the parotid gland is frequently found to have a mixed tumor of salivary tissue origin. However, less common lesions occur in the anatomical region of the parotid gland. These pathological entities deserve consideration in the differential diagnosis. This report presents nine patients with unusual lesions occurring in the parotid region. These regions include cervicofacial actinomycosis, branchial cleft cyst, parapharyngeal tumors, bony lesion of the mandible, non-parotid origin malignant tumor, and metastatic malignant tumors. Each class of lesions demonstrated is also discussed.- - - - - - - - - - ranking = 0.33333333333333keywords = gland (Clic here for more details about this article) |
