Solitary extramedullary plasmacytoma of the thyroid gland.

Solitary extramedullary plasmacytoma of the thyroid gland is an uncommon condition. Up to date, its clinical pathological features are not fully understood. We present a case of an extramedullary nonmucosal plasmacytoma of the thyroid gland which is the first case with regional metastatic lymph nodes. This condition requires a scrupulous survey to rule out a metastatic multiple myeloma. Although localized forms management is still controversial, authors require combined approach for regional metastatic forms. The prognosis is favorable compared to solitary bone plasmacytomas or multiple myeloma.

[Desmoid infantile mandibular fibromatosis]. / Fibromatose desmoïde infantile de la mandibule.

INTRODUCTION: A desmoid tumor, or aggressive fibromatosis, is a benign fibrous tumor with a high potential for locoregional extension. This tumor is very rarely located in the mandible. OBSERVATION: A 2-year-old boy presented with an extensive mandibular desmoid tumor. The diagnosis was proved on histological examination. Two years after surgery, there was no recurrence. DISCUSSION: Aggressive fibromatosis is rarely located in the mandible. The differential diagnosis with malignant tumors is difficult. Surgery is the first-line treatment. However, alternative therapies should be considered, especially in children, to avoid mutilating operations.

[Exophthalmos arising from paranasal sinuses]. / Exophtalmie d'origine naso-sinusienne en ORL.

INTRODUCTION: Proptosis due to intraorbital process is frequent and secondary to various aetiologies. Its findings in ENT practice is the sign of a serious complication. The purpose of this study is to review a series of patients who presented an exophtalmy. MATERIAL AND METHODS: We conducted a retrospective analysis of 15 patients with exophthalmos complicating a rhinosinusal benign disease, diagnosed and treated in our department between January 2003 and December 2010. As their management is different, we excluded all cases of orbital cellulitis. RESULTS: Average age of presentation was 38 years, without sex predominance. Exophthalmos was unilateral, non axial and irreductible in all cases. The average duration of symptoms installation was 18 months. The most common aetiology was fronto-ethmoidal osteomas (9 cases), followed by fronto-ethmoidal mucoceles (5 cases) and spheno-orbito-frontal fibrous dysplasia (1 case). The functional prognosis of the affected eye depended on the aetiology and the degree of ocular injury. CONCLUSION: In our experience, sinusal causes of exophthalmos comprise osteomas and ethmoidal mucoceles. Medical history, clinical and radiological data as provide the diagnostic. In case of benign tumours, surgery is the curative treatment.

[Tuberculosis of the parotid gland]. / Tuberculose de la glande parotide.

INTRODUCTION: The aim of this study is to emphasize the difficulties of diagnosing parotid gland tuberculosis because of its non specific symptoms and to incite the physician to seek it more frequently. MATERIAL AND METHOD: Six cases of parotid gland tuberculosis were diagnosed within a 4-year period and included in a retrospective study. RESULTS: There were two men and four women, mean age 45 years. Four patients underwent superficial parotidectomy with frozen section analysis which enabled us to rectify the diagnosis. Medical treatment was based on a 6-month course of bactericidal chemotherapy. Outcome was favorable in all the cases with nine months average follow. DISCUSSION: Symptoms of parotid gland are misleading, pathologic findings are of increasing importance for diagnosis, which with the new serology techniques may improve further.

[Actinomycosis of the middle ear: case report]. / Actinomycose de l'oreille moyenne: à propos d'un cas et revue de la littérature.

INTRODUCTION: Actinomycosis of the middle ear are rare and often atypical and remain ignored for a long time. This delayed the diagnosis and obscured the forecast of the disease. AIM OF STUDY: Our objective is to give a progress report on this affection in the light of a new observation and data of the literature. CLINICAL CASE: 58 year old patient who consults of a left chronic otitis media with a posterior perforation. A CT scan had shown a filling of the middle ear in favour of a cholesteatoma. A tympano-mastoidectomy was realized and the histological examination of the product of excision had sowed that it acts of an actinomycosis of the middle ear. The treatment consisted of penicillin for 5 months. The continuations are good after 14 months of follow-up. CONCLUSION: The actinomycosis of the middle ear must be known to evoke the diagnosis in various clinical circumstances. Its diagnosis makes it possible to adopt an adapted and non aggressive therapeutic attitude, avoiding heavy surgical gestures, sources of complications or after-effects. The antibiotherapy containing penicillin is the essential element, either separately, or in complement of gestures of surgical drainage.

[Benign cementoblastoma. Apropos of a case and review of the literature]. / Le cémentoblastome bénin. A propos d'un cas et revue de la littérature.

The cementoblastoma is a rare benign tumor of odontogen origin that interests the roots of the teeth especially the lower molars. The evolution is often silent, the radiological exam is not specific, the diagnosis of certainty is histological. The surgical treatment assures the recovery without aftermath. The authors report a case of cementoblastoma at a patient of 37 years for which he has benefited of a resection by vestibular way and debate diagnosis and therapeutic modes of this affection.
