Adenoid cystic carcinoma, or cylindroma, usually presents in the salivary glands or in the upper respiratory passages. We report an unusual case of adenoid cystic carcinoma in a 45-year-old woman who presented with a three-year history of progressive right trigeminal sensory palsy, most pronounced in the second division. There was, in addition, a right trigeminal motor palsy and a partial right...

INTRODUCTION Adenoid cystic carcinoma is a malignant neoplasm most commonly originating in the salivary glands. Its occurrence elsewhere is rare and its metastasis to the thyroid gland has been described only once. CASE REPORT We describe the case of a 66-year-old man who presented for a swelling in the midline neck of six months duration. A solitary palpable nodule was identified in the isth...

BACKGROUND: The metastatic ability of tumor cells is determined by level of expression of specific genes that may be identified with the aid of cDNA microarray containing thousands of genes and can be used to establish the expression profile of disease related genes in complex biological system. MATERIALS AND METHODS: Salivary adenoid cystic carcinoma cell line and its high metastases adenoid c...

PURPOSE OF REVIEW This purpose of this article is to review and provide an update of current publications on the evaluation and management of adenoid cystic carcinoma. RECENT FINDINGS Adenoid cystic carcinoma is an uncommon salivary gland malignancy that presents insidiously and is generally advanced when diagnosed. Current effective treatment modalities include surgery and irradiation, but l...

Introduction: Natural killer (NK) cells, of which CD56 is a specific marker, play an important role in host defense against tumors. Cancer stem cells, of which aldehyde dehydrogenase isoform 1 (ALDH1) is an immunohistochemical marker, are a group of tumorigenic cells which are involved in migration and tumor recurrences. We aimed to evaluate the expression of ALDH1 and CD56 in common salivary g...

A case of an adenoid cystic carcinoma of the minor salivary glands of then nasal cavity is reported. The tumour had spread locally and by perineural spread to the internal auditory mentus, causing facial nerve palsy.

  Background and Objectives: Adenoid cystic carcinoma (ACC), the most common malignant tumor of submandibular and minor salivary glands, is characterized by a high rate of local recurrence and distant hematogenous metastasis and tendency to invade peripheral nerves. In spite of radiotherapy and surgical treatment, the long-term prognosis is dismal. Today, many studies are being conducted using...

SUMMARY We report the CT and MR imaging findings in a patient with malignant peripheral nerve sheath tumor in the right nasolabial area, which exhibited typical imaging features of cystic adenoid carcinoma.

We compared 4 breast cylindromas with 50 dermal cylindromas and 8 adenoid cystic breast carcinomas. Except for a modest increase in the number of eccrine ducts and reactive Langerhans cells in dermal cylindromas, breast and dermal cylindromas showed identical histologic and immunohistochemical features. Both were characterized by epithelial islands containing central basaloid cells and peripher...

INTRODUCTION Adenoid cystic carcinoma (ACC) of the breast is a rare condition, and cases in male patients are even less common. CASE We describe a case of ACC of the breast with axillary lymph node metastasis, disseminated osteolytic bone metastasis and bone marrow involvement in a 41-year-old man. CONCLUSION Male breast ACC is an extremely rare malignancy; there can be difficulty in obtain...
