Neck epidermoid cyst mimicking tuberculosis at ultrasound: Case report and review of literature.

Neck masses in children can be inflammatory, congenital or neoplastic. When a congenital cyst becomes infected repeatedly, it may mimic inflammatory disease and the diagnosis may be challenging with ultrasound. An increasing incidence of infection with non-tuberculous mycobacterial organisms has been observed in recent decades in children with cervical lymphadenopathy. An ultrasound scan performed during the infectious phase of a mass can be misleading and can lead to an incorrect diagnostic hypothesis with the risk of erroneous medical and surgical therapies. We describe a case of a lateral neck epidermoid cyst mimicking and misdiagnosed as a tuberculous lymphadenopathy at ultrasound scan and treated with primary surgical excision. After surgery, a histological diagnosis of an epidermal cyst was made. There were no signs of recurrence during the 12-month follow-up period. A review of the literature and a proposed practice pathway for lateral cervical lymphadenopathy in children is also reported.

Iron supplement tablet embedded in the oral cavity mimicking neoplasm: a case report.

The detection of foreign bodies in the upper-aerodigestive tract is a fairly frequent event and can occur in various areas and for various reasons. In rare cases, foreign bodies can simulate a neoplasia. We evaluated similar cases during emergency regimen with an oral cavity mucosal lesion, causing lockjaw, sore throat, dysphagia, and swelling of the submandibular and laterocervical region. Physical examination revealed an extensive mucosal ulceration in the floor of the mouth and the lateral surface of the tongue, comparable to oral cancer. During a second, more accurate assessment, a partially deteriorated iron supplement tablet was found embedded in a mucosal pocket. After removing the tablet, gradual normalization of the tissue was observed without any sequelae. This is one of the many reasons why it is advisable and useful in cases of oral lesions to collect a detailed medical history and to perform an accurate clinical evaluation, including inspection and palpation of the lesion, before proceeding to further diagnostic assessments, especially in elderly patients taking many medications. However unlikely, it is possible that difficulty in swallowing pills or tablets could generate tumorlike lesions.

Cervical necrotizing fasciitis of odontogenic origin involving the temporal region--a case report.

Necrotizing fasciitis (NF) is a soft-tissue infection, usually polymicrobial, that causes necrosis of fascia and subcutaneous tissue while sparing skin and muscle. We report a case of cervical NF complicating dental infection in a 50-year-old woman, who presented with infection involving mucosa of the right mandible and temporal muscle, and masticator spaces, requiring extensive surgery and antibiotic therapy. Prompt diagnosis and immediate aggressive surgical debridement of all compromised tissues are critical to reducing morbidity and mortality in these rapidly progressive infections.

Lung cancer presenting with trigeminal neuropathy.

The purpose of this case report is to describe MR imaging and CT findings of a patient in whom the first clinical and neuroradiological manifestation of a metastatic lung adenocarcinoma was unilateral trigeminal neuropathy caused by a presumed metastasis involving cisternal and Meckel's cave segments of ipsilateral trigeminal nerve. MR imaging and CT scan differential diagnosis of expansive lesions of the intracranial trigeminal nerve must include metastases. Physicians and neuroradiologists must be aware of metastases as an uncommon cause of trigeminal neuropathy, even as the presenting condition of cancer.
