introduction: tonsillectomy with or without adenoidectomy is one of the most frequent surgical procedures especially in children. several indications and contraindications have been suggested for this procedure. the benefits and the negative results of this operation have been studied by different researchers; nevertheless, to date, it is still a common procedure. the main purpose of this study...
OBJECTIVES/HYPOTHESIS To propose a definitive standard grading scale in the assessment of adenoid tissue in relation to size, position, and proximity to surrounding anatomic structures. This will allow for better clinical communications among practitioners when treating this pathology, a better understanding of its relationship and how it effects neighboring structures (eustachian tube and choa...
We present a case report of an auxiliary nurse who developed an adenoid cystic carcinoma in her left maxillary sinus following occupational exposure to formaldehyde in the operating theatre. Currently, the epidemiological evidence that formaldehyde can cause cancer in humans is considered to be limited. Previous case-control-studies of formaldehyde and sinonasal cancer have mainly investigated ...
The morphology, incidence and distribution of hyaline cells in ten cases each of pleomorphic adenoma, adenoid cystic carcinoma, adenocarcinoma and mucoepidermoid tumour were studied by conventional light microscopy. Results showed that the hyaline cells were identified in 60% of pleomorphic adenoma and in 20% of mucoepidermoid tumours, but were absent in adenoid cystic carcinoma and adenocarcin...
Renal metastasis of a submandibular gland adenoid cystic carcinoma is clinically rare when it presents with an atypical imaging appearance of singular renal metastases. Whole-body positron emission tomography (PET)/computed tomography (CT) can determine whether the singular renal mass is benign or malignant and identify metastases in other parts of the body, particularly in uncommon sites. In t...
Adenoid cystic carcinoma is a cancer of the salivary gland that primarily affects the parotid, submandibular, and accessory salivary glands. Its growth is slow and it has infiltrative nature. A 46-year-old female patient coming from the rural area presented a lesion on the palate and reported pain in the region for three years. After incisional biopsy, and histopathological diagnosis of adenoid...
A 23 year old man presented with a tumour mass in the lung. Subsequent investigation showed ectopic secretion of adrenocorticotrophic hormone (ACTH) and growth hormone releasing hormone (GHRH) from an adenoid cystic carcinoma. The patient progressed to show the clinical effects of long term exposure to high blood levels of both growth hormone and cortisol. The case was complicated by pituitary ...
Choroidal metastasis rarely reveals a primary cancer. At this stage, they are associated with multiple metastases. Adenoid cystic carcinoma also known as cylindroma is very rare and constitutes 1% of major and minor salivary glands malignancies. In the parotid gland, the ACC is relatively rare, constituting only 2–3% of all tumors. The purposes of this study are to report the first case of paro...
Basaloid squamous cell carcinoma (BSCC) is a rare and aggressive variant of squamous cell carcinoma (SCC) that occurs preferentially in the upper aerodigestive tract. We present two cases of BSCC, one arising in the conjunctiva and the other arising in a paranasal sinus. Clinical and pathological findings in these two cases, including immunohistochemistry is presented along with brief discussio...
OBJECTIVE To evaluate the incidence of unexpected histologic findings in routine tonsillectomy and adenoidectomy specimens. METHODS A retrospective medical record review was performed at a tertiary care children's hospital. The pathology records of 2062 children who underwent tonsil or adenoid surgery were analyzed and the final histologic diagnosis was recorded. RESULTS Four unexpected his...
