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...

SMAD4, also known as DPC4 (deleted in pancreatic carcinoma 4) was initially identified as a tumor-suppressor gene. It is located on 18q21, a region frequently deleted in pancreatic carcinoma. Functionally inactivating mutation of the gene also occurs in many cases of pancreatic cancer. Functional loss of SMAD4 is frequently detected not only in pancreatic carcinoma but also in colorectal carcin...

Adenoid cystic carcinoma (ADCC) is a pathology aff ecting exocrine glands originating primarily from the minor salivary glands. Although rare in incidence, but there are cases of seeding of cells of adenoid cystic carcinoma into intracranial sites via diff erent routes. We report of an intriguing case of remote metastasis of an intracranial tumor in the pituitary diagnosed as pituitary adenoma ...

Adenoid cystic carcinoma is a rare epithelial tumour, and comprises about 1% of all malignant tumours of the oral and maxillofacial region. It is a malignant tumour which may develop in the trachea, bronchus, lungs or mammary glands, in addition to the head and neck region. Occurrences in the head and neck are mostly detected in the major salivary gland, oral cavity, pharynx and paranasal sinus...

Adenoid Cystic Carcinoma (ACC) is a rare tumor constitutes for less than 1% of head and neck malignancies and 10% of all salivary gland tumors. Palate is the most common site to be involved in the oral cavity followed by parotid gland and submandibular gland. They are usually asymptomatic, slow growing, characteristically shows infiltrative growth and perineural invasion. This paper reports a c...

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...
