Tonsillar tuberculosis mimicking tonsillar carcinoma: A case report.

INTRODUCTION: Extrapulmonary tuberculosis is rare even in endemic areas, and is dominated by lymph node involvement. Tonsillar tuberculosis is exceptional. The clinical examination and radiological explorations are non-specific. CASE PRESENTATION: A 45-year-old woman presented with chronic odynophagia and otalgia. Examination revealed an enlarged left palatine tonsil with an irregular surface and a firm consistency. Radiologic exploration was not specific. The patient underwent a tonsillar biopsy. Histopathology was consistent with tuberculosis and the patient was put on antitubercular drugs. CLINICAL DISCUSSION: Tuberculosis is a global public health problem. Extrapulmonary tuberculosis is rare and mainly affects lymph nodes. Tonsillar tuberculosis is frequentely seen in individuals with immunodeficiency. Clinical features and imaging findings are non-specific. Diagnosis is based on histopathological and microbiological findings to rule out differential diagnoses especially cancer. Treatment is based on anti-tuberculosis drugs. CONCLUSION: Our case illustrates a rare presentation of primary tuberculosis and highlights the importance of considering tuberculosis as a potential cause of tonsillitis.

Multiple Retained Needles in the Neck of a Drug User: A Case Report.

Retained needles are frequently observed in intravenous drug users. However, an incidental discovery of multiple needles at the neck seldom occurs. These foreign bodies remain either asymptomatic or cause local and central complications that can be fatal. We report the case of a 43-year-old male having a medical record of human immunodeficiency virus and hepatitis C who presented to our department with a 3-day history of a febrile lateral neck swelling. He reported a history of repetitive intravenous drug use and previous abscesses that were surgically drained. We noted a left and tender 8 cm neck swelling with torticollis. Computed tomography scan showed a collected myositis of the sternocleidomastoid muscle in association to multiple metallic foreign bodies at the neck that were compatible with the aspect of broken needles. Imagery also showed a thrombosis of the ipsilateral jugular vein. No central embolism of a foreign body was noted. We performed a surgical drainage of the muscular abscess and managed to retrieve a 1 cm broken needle that was retained at the level of the collection. We did not retrieve the other needles since they were asymptomatic. The patient was placed under intravenous antibiotics for 1 week followed by oral amoxicillin-clavulanate with a total regression of the cellulitis. At the further follow-ups, the rest of the foreign bodies remained asymptomatic. Our study emphasizes on the importance of suspecting a retained foreign body in intravenous drug users to ensure an adequate management of the possible complications and to protect the medical team from incidental needle injuries.

HBHA-IGRA and cytotoxic mediators release assays for the diagnosis of cervical tuberculous lymphadenitis.

IMPORTANCE: Cervical tuberculous lymphadenitis (CTL), the most frequent extrapulmonary form of tuberculosis, is currently a major health problem in Tunisia and in several regions around the world. CTL diagnosis is challenging mainly due to the paucibacillary nature of the disease and the potential misdiagnosis as cervical non-tuberculous lymphadenitis. This study demonstrates the added value of the heparin-binding hemagglutinin-interferon-gamma release assay as an immunoassay in the context of CTL.

A superior ophthalmic vein thrombosis following an acute pansinusitis: A case report.

INTRODUCTION AND IMPORTANCE: Superior ophthalmic vein thrombosis (SOVT) is a very rare condition that can occur following either septic or aspetic causes. Early recognition and management is important in order to avoid vision-threatening and fatal complications. CASE PRESENTATION: A 28-year-old man presented with orbital cellulitis complicating acute pansinusitis. CT scan revealed ipsilateral SOVT. The patient received intravenous antibiotics and anticoagulation with strict ophthalmic monitoring. No orbital complications were recorded during the course of treatment. CLINICAL DISCUSSION: SOVT is caused either by septic or aseptic causes. Treatment depends on the etiology. Corticosteroids and anticoagulants are controversial. CONCLUSION: Early diagnosis is key to successful management of SOVT.

Synchronous parathyroid carcinoma and papillary thyroid carcinoma.

The simultaneous occurrence of parathyroid carcinoma and nonmedullary thyroid carcinoma is unusual. We report the case of 60-year-old woman who was found to have concurrent parathyroid carcinoma with severe clinical manifestations of primary hyperparthyroidism in addition to an incidental papillary thyroid carcinoma. Parathyroid hormone level was 569 pg/ml (normal range 10-65), and the serum calcium concentration was 13.83 mg/dl (normal range, 8.8-10.4). Preoperative investigation found a large 3 cm anterior cervical nodule suggestive of parathyroid adenoma. Total thyroidectomy and left parathyroidectomy were performed, and the final anatomopathological examination of the operative specimen concluded the coexistence of papillary microcarcinoma and parathyroid carcinoma. Although parathyroid carcinoma is an uncommon cause of hypercalcemia, it should be considered when severe hypercalcemia is observed, and in case of coexistence of thyroid nodules. The possibility of both malignancies must also be considered since parathyroid and nonmedullary thyroid carcinoma rare cases have previously been reported.

Accuracy of fine-needle aspiration cytology in the diagnosis of salivary gland masses according to the Milan reporting system and to an in-house system.

BACKGROUND: This study aims to assess in our institutional experience the accuracy of fine needle aspiration cytology (FNAC) in the diagnosis of salivary gland masses (SGM) according to the Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) and to an in-house system. METHODS: The study included 189 FNACs conducted between January 2011 and December 2019. The FNACs, classified according to the in-house system, were reclassified according the MSRSGC. Taking histopathology as gold standard, the measures of diagnostic accuracy of FNAC were determined for suspicion for malignancy (SFM) and malignant categories. RESULTS: According to the in house system, FNAC diagnoses were classified as: 23 (12.2%) non-diagnostic (ND), 23 (12.2%) non-neoplastic (NN), 119 (62.9%) benign neoplasm (BN), 10 (5.2%) indefinite neoplasm (IN), 2 (1.1%) SFM, and 12 (6.4%) malignant (M). Based on the MSRSGC, there were 3 (1.5%) cases of atypia of undetermined significance (AUS) and 7 (3.7%) neoplasms of uncertain malignant potential (SUMP). The number of ND, NN, BN, SFM, and M cases were identical in the two systems. For both systems, the sensitivity, the specificity, the positive predictive value, the negative predictive value, and the accuracy for malignancy diagnosis were 77.8%, 100%, 100%, 97.6%, and 97.8%, respectively. CONCLUSION: According to the MSRGC and to our in-house reporting system, FNAC is an accurate technique for the diagnosis of malignant salivary tumors with excellent specificity and good sensitivity. However, MSRGC has the advantage of standardization of salivary gland cytology reporting.

Performance of GeneXpert ultra in the diagnosis of Tuberculous Cervical lymphadenitis in formalin fixed paraffin embedded tissues.

The diagnosis of Tuberculous Cervical lymphadenitis (TCL) is challenging. The present study aimed to assess the performance of GeneXpert ultra (GXu) in the diagnosis of TCL on Formalin Fixed, Paraffin Embedded Tissues (FFPET). This study included 35 TCL cases confirmed by positive microbiology and/or positive GXu on Fresh Tissues (FT). The diagnostic performance parameters of GXu on FFPET were determined with reference to microbiology (positive Ziehl Neelsen and/or positive culture) and with reference to positive microbiology and/or positive GXu on FT. The GXu on FFPET was positive in 26/35 (74%) cases. With reference to positive ZN and or culture, the sensitivity, specificity, positive predictive value, and negative predictive value of GXu on FFPET were 63%, 100%, 100% and 71% respectively. With reference to positive microbiology and/or positive GXu on FT, these rates were 74%, 100%, 100% and 40% respectively. GXu on FFPET is a reliable tool for the detection of Mycobacterium tuberculosis complex particularly for cases where microbiological investigations have not been performed.

Evaluation of fine needle aspiration cytology in the diagnosis of cervical lymph node lymphomas.

PURPOSE: Surgical biopsy examination is the gold standard for the diagnosis of lymph node lymphomas. Fine-needle aspiration cytology (FNAC) is a quick and safe method in the management of cervical lymph nodes. Its value in confirming recurrent or residual lymphoma is well established. However, its role in the primary diagnosis of lymph node lymphoma remains controversial. The aim of this study was to assess, in our experience, the reliability of FNAC in the diagnosis of cervical lymph node lymphomas. MATERIALS AND METHODS: This was a retrospective study carried out over a 6-year period (January 2011 to December 2016) and conducted at the Cytology Unit in our Pathology Department (Charles Nicolle Hospital, Tunisia). The measures of diagnostic accuracy of FNAC in the diagnosis of cervical lymph node lymphomas were calculated taking histopathology as the gold standard. RESULTS: A total of 937 FNA samples were obtained from 851 patients. The diagnosis of lymphoma was obtained in 65 cases (6.9%). Cytological diagnoses of lymphoma were as follows: 28 (44%) Hodgkin lymphoma, 17 (25%) high-grade lymphoma, 15 (23%) low-grade lymphoma, and 5 (8%) "suggestive of lymphoma." FNAC of cervical lymph nodes had a sensitivity of 95.5%, specificity of 98.7%, positive predictive value (PPV) of 97.7%, and negative predictive value (NPP) of 97.5%. CONCLUSION: The present study demonstrated that cytology is capable to detect nodes suspicious for the presence of lymphoma precisely, in terms of low- or high-grade lymphoma, which is a relevant and very achievable first step in the management of patients with cervical lymph node lymphoma.

Efficacy of Fine-Needle Aspiration Cytology in the Diagnosis of Tuberculous Cervical Lymphadenitis.

OBJECTIVE: This study assesses the role of fine-needle aspiration cytology (FNAC) in the diagnosis of tuberculous lymphadenitis (TL) in comparison with histology and bacteriology findings. STUDY DESIGN: We undertook a descriptive retrospective study of 937 FNAC specimens from 851 patients with cervical lymph nodes. The FNAC findings were then compared to histopathology and bacteriology. RESULTS: Of the 937 aspirates, the cytopathological diagnoses consisted of 426 (55.9%) TL, 185 (24.3%) reactive lymphoid hyperplasia, 18 (2.3%) suppurative inflammation, 78 (10.2%) malignant metastatic tumor, and 54 (7%) lymphoma. Of the 426 TL cases, 171 were diagnosed by FNAC combined with bacteriological examination. In this group, 22 cases were found to be positive on Ziehl-Neelsen stain and 16 by culture. A histopathology report was available for 62 cases. Compared to histopathology, the overall diagnostic sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of FNAC in the diagnosis of cervical TL were, respectively, 96.77, 100, 100, and 96.67%. When comparing bacteriology to histopathology, these values were 97.44, 100, 100, and 91.67%. CONCLUSION: Our study shows that FNAC is a sensitive and specific tool for the diagnosis of cervical TL.

Ectopic lingual thyroid.

Ectopy of the thyroid gland is an abnormal embryological development. Its occurrence in children is rare. In this study, we report the case of a 12-year-old girl that presented with dysphagia and nocturnal dyspnea. Magnetic resonance imaging confirmed the presence of a lingual thyroid. Thyroid scintigraphy showed intense and elective uptake of radiotracer at the base of the tongue. Hormonal tests revealed hypothyroidism. Treatment consisted of opotherapy based on levothyroxine. Evolution has been favourable and the patient showed significant improvement with reduction of the dyspnea and the dysphagia and normalization of thyroid hormone tests.

Association of the long QT syndrome With goiter and deafness.

We report on the long QT syndrome occurring in conjunction with nontoxic multinodular goiter and sensorineural deafness in several siblings of a large family. Autosomal and X-linked recessive and dominant modes of inheritance are possible for the different phenotypes. The affected family members had various phenotype combinations, suggesting variable expressivity and incomplete penetrance.

[Cervico-facial lymphatic malformations in adults]. / Les malformations lymphatiques cevico-faciales de l'adulte.

Lymphatic malformations are due to an abnormality in lymphatic development only rarely present in adults. Their prognosis is better than those of infants. We report 6 cases of lymphatic malformations of head and neck in adults reviewed from 1990 to 2001. The treatment was surgical in 5 cases. Surgical excision is the treatment of choice and reccurences are rare.
