Nodular fasciitis of parotid region: A pitfall in the diagnosis of pleomorphic adenomas on fine-needle aspiration cytology

DIAGNOSTIC CYTOPATHOLOGY, Issue 3 2005
Ph.D., Reda S. Saad M.D.
Abstract Fine-needle aspiration cytology (FNAC) is routinely employed for the preoperative diagnosis of salivary gland lesions. Although most cases show morphologic features characteristic of specific entities, some lesions can be diagnostically challenging. We report two parotid aspirates, initially diagnosed as pleomorphic adenoma on FNA. The patients, a 33-yr-old white man, and a 24-yr-old white woman, presented with indurated lesions arising in the parotid gland region. The aspirates from both patients were markedly hypercellular. Smears showed a mixture of spindle cells with a well-demarcated cytoplasm showing occasional long cytoplasmic process; and cells with abundant cytoplasm with round to oval eccentric nuclei, giving the impression of plasmacytoid cells of pleomorphic adenoma. The nuclear chromatin was evenly distributed and finely granular with one or two occasional small nucleoli. Intermingled with the tumor cells were scattered neutrophils, eosinophils, and macrophages. Aggregates of spindle cells were also seen embedded in a mucoid background with occasional small tufts of a fibrillar mucoid stroma. These fibrillar tufts were magenta red in the Diff-Quik stain, giving the impression of matrix of pleomorphic adenoma. Both cases were later diagnosed on histologic examination as nodular fasciitis. Nodular fasciitis should be considered in the differential diagnosis of a mass arising in association with the parotid gland. Diagn. Cytopathol. 2005;33:191,194. © 2005 Wiley-Liss, Inc. [source]

Pyometra with inguinal herniation of the left uterine horn and omentum in a Beagle dog

JOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE, Issue 1 2007
Christopher G. Byers DVM
Abstract Objective: To describe a unique case of pyometra with inguinal herniation of the left uterine horn and omentum. Case summary: A 7-year-old, 19 kg, intact female Beagle dog presented for surgical treatment of presumptive pyometra and biopsy of a caudal abdominal mass in the left inguinal mammary gland region. Ventral midline celiotomy was performed, and a distended, fluid-filled uterus with passage of the distal aspect of the left uterine horn through the left vaginal process into the inguinal canal was identified. The patient recovered uneventfully following ovariohysterectomy and left inguinal herniorrhaphy. New or unique information provided: This is the first documented report of inguinal herniation of a uterine horn associated with a pyometra. [source]

Pilocarpine for the treatment of salivary glands' impairment caused by radioiodine therapy for thyroid cancer

ORAL DISEASES, Issue 3 2006
DJ Aframian
Objectives:, To study the effect of single-dose pilocarpine hydrochloride 5 mg on the whole unstimulated and stimulated salivary flow in patients suffering from thyroid cancer treated with radioiodine therapy, and to investigate the changes in vital signs during the treatment. Subjects and methods:, Five such patients were referred with complaints of dry mouth, rampant caries, and pain in the parotid gland region or history of chronic recurrent suppurative sialodenitis. A single dose of 5 mg pilocarpine hydrochloride was administered to each patient and blood pressure, heart rate, body temperature and salivary secretion rate were monitored at 1, 2 and 3 h. Results:, A significant elevation of unstimulated and stimulated saliva flow rate was observed in four patients without significant alteration of the monitored vital signs. Conclusions:, Treatment with pilocarpine hydrochloride may be beneficial in the case of impaired salivary function in patients treated with radioiodine. [source]

Morphological Features of the Stomach of Malayan Pangolin, Manis javanica

ANATOMIA, HISTOLOGIA, EMBRYOLOGIA, Issue 5 2010
C. Nisa'
With 6 figures Summary The morphology of the stomach of Malayan pangolin, Manis javanica was studied at macroscopic, light microscopic, and scanning electron microscopic levels. The stomach of M. javanica was C-shaped with short lesser curvature. At the oesophageal junction, the inner smooth muscle was thickened in the greater curvature side. The entire stomach was lined by a thick cornified stratified squamous epithelium, except at the duct orifices of glands and in the pyloric gland region. The wall of the fundus was thin and devoid of glands. The gastric glands consisted of mucous, oxyntic, and pyloric glands. The mucous glands were observed in the lesser curvature (Mg-L), in the greater curvature (Mg-G), and in the pyloric canal (Mg-C) respectively. The oxyntic glands were organized into gland mass, making an oval mound elevated to the gastric lumen, in the middle of the greater curvature. The oxyntic gland mass has a single common duct with opening directed to the pyloric side. This duct was surrounded by mucus gland (Mg-G). The pyloric glands were located caudal to the pylorus. There was no sphincter at the pyloric-duodenal junction. Large mucosal protuberance, the torus pyloricus was observed in the side of the lesser curvature of the pyloric canal. In the lumen of pyloric canal region, numerous spines and small pebbles were observed. The muscle layers in the wall of this region were considerably thickened. The present results on the stomach of M. javanica are thought to be closely related to the toothless and eating habits of this animal species. [source]

Thyroid gland neurofibroma in a NF1 patient

ACTA NEUROLOGICA SCANDINAVICA, Issue 1 2002
M. Anagnostouli
Neurofibromas are a hallmark of neurofibromatosis type 1 (NF1). They are usually benign and rarely present in the thyroid gland region. There is a suspected association between NF1 and intramedullary thyroid carcinoma and there is a well-known association between NF1 and pheochromocytoma. Here, we present a 55-year-old man with typical symptoms of NF1, whose course was complicated by a neurofibroma of the thyroid gland. His clinical spectrum of symptoms included bilateral cataract established before the age of 35 years, quadriparesis and an intrathoracic mass. The patient died because of abdominal carcinomatosis of unknown origin. The rarity of thyroid gland neurofibroma is discussed here, emphasizing the importance of early detection of these and other NF1 complications, also including the risk of malignant transformation with lethal outcome.
