Giant submandibular gland mucocele as a complication of previous sialolith removal.

Mucoceles are common lesions of minor salivary glands. Mucoceles of the major salivary glands including the submandibular gland are extremely rare, but should be considered in the differential diagnosis of submandibular space swellings. We present a rare case of a 25-year old man, who was diagnosed with a submandibular gland mucocele and had a history of sialolithiasis and intraductal sialolith excision, as well as numerous evacuating punctures and needle aspirations of the mass. The cyst was surgically excised and the specimen included the sublingual gland, in order to prevent recurrence. No postoperative complications were noted.

Transoral Resection of Giant Parapharyngeal Space Tumors via a Combined Surgical Approach.

INTRODUCTION: Parapharyngeal space (PPS) tumors account for 0.5% of the head and neck neoplasms. Based on the evidence, 80% of these tumors are of a benign nature. Surgical excision is the treatment of choice for this condition. The present study was conducted to propose transoral resection as an efficient way to excise the benign well-defined tumors of the PPS. MATERIALS AND METHODS: This retrospective case series study was conducted on seven patients undergoing the transoral excision of the sizeable masses of the PPS via a combined approach. Computed tomography and magnetic resonance scans revealed giant masses in the PPS in all cases. These neoplasms were preoperatively diagnosed as well-delineated, non-vascular, and benign. RESULTS: All patients underwent transoral tumor excision preceded by an auxiliary transcervical approach, which served as an assurance for the dissection and preservation of the cranial nerves and neurovascular bundle without any tumor spillage. Average hospital stay was limited to a maximum of 3 days, and all patients had an uneventful postoperative course. The follow-up examination did not indicate any recurrence. CONCLUSION: Based on the findings, transoral resection can be concluded as an efficient way to excise benign, well-defined tumors of the PPS. This procedure appears to be safe when a secondary transcervical approach is applied. Given the unnecessity of performing mandibulotomy in this procedure, it is expected to have lower morbidity and fewer complications.

Ceruminous Adenoma of the External Auditory Canal: A Case Report with Imaging and Pathologic Findings.

Ceruminous adenomas are benign tumors that are rare in humans and present with a nonspecific symptomatology. The treatment of choice is surgical excision. We present an 87-year-old woman who presented with a reddish, tender, round, soft mass of the outer third of the inferior wall of the left external auditory canal, discharging a yellowish fluid upon pressure. Coincidentally, due to her poor general condition, this patient also showed symptoms consistent with chronic otitis media, parotitis, and cervical lymphadenopathy, such as otorrhea, through a ruptured tympanic membrane and swelling of the parotid gland and cervical lymph nodes. The external auditory canal lesion was surgically excised under general anesthesia, utilizing a transmeatal approach. The pathological diagnosis was ceruminous gland adenoma. The tumor was made of tubular and cystic structures and embedded in a fibrous, focally hyalinized stroma. Immunohistochemistry confirmed the presence of two distinct cell populations. The luminal cells expressed keratin 7, while peripheral (basal) cells expressed keratins 5/6, S100 protein, and p63. The apocrine gland-related antigen GCDFP-15 was focally expressed by tumor cells. The postoperative course was uneventful and at the 2-year follow-up no recurrence of the ceruminous adenoma was noted.

Ciprofloxacin induced acquired long QT syndrome in a patient under class III antiarrhythmic therapy.

We report one case of cardiac arrest related to ciprofloxacin administration. One female patient (aged 70 years old) developed a marked QTc prolongation (QTc = 0.62 s) within 24 hours of ciprofloxacin administration, with documented torsades de pointes and recurrent syncope that required defibrillation. The patient was under amiodarone and sotalol therapy for atrial fibrillation, with no obvious QT prolongation prior to ciprofloxacin therapy. QT prolongation and subsequent torsades de pointes appeared only after initiation of ciprofloxacin and normalized after drug discontinuation. Even though ciprofloxacin is thought to be safer than other agents in its class, it may cause QT prolongation and torsades de pointes, particularly in high risk patients with predisposing factors. Prolongation of the QT interval related to the effect of fluoroquinolones on rapid potassium channels (IKr) may result on potentially serious proarrhythmic effect, leading to torsades de pointes.
