Solitary extramedullary plasmacytoma of the parotid gland in a patient with mixed connective tissue disease.

Solitary extramedullary plasmacytomas of the head and neck region are rare entities. Very few have been described in the parotid gland. They can clinically and radiologically mimic the rather common benign tumors of the parotid gland (pleomorphic adenoma and Wharthin's tumor), and subsequently the need careful consideration by the involving surgeon and pathologist is needed for a proper diagnosis.

Is there an association with Wilson's disease and multiple tongue dysplasia lesions and in situ carcinoma? A case-report based literature review.

Wilson's Disease (WD) is a rare autosomal recessive hereditary disease with copper accumulation in the body, particularly the liver, brain and cornea. WD is widely treated with chelation agents who enable the copper excretion. Since high concentrations of copper are toxic, WD is associated with hepatocellular carcinoma and cholangiocarcinoma, with low incidence of other types of cancer.

Odyssey of an elbow synovial chondromatosis.

Synovial chondromatosis of the elbow is an uncommon condition. However, a chondrosarcoma arising from the former is remarkably rare. The authors report a case of an elbow chondrosarcoma secondary to synovial chondromatosis in a 38-year-old woman.

Extrapelvic endometriosis: a rare entity or an under diagnosed condition?

Endometriosis is a clinical entity characterized by the presence of normal endometrial mucosa abnormally implanted in locations other than the uterine cavity. Endometriosis can be either endopelvic or extrapelvic depending on the location of endometrial tissue implantation. Despite the rarity of extrapelvic endometriosis, several cases of endometriosis of the gastrointestinal tract, the urinary tract, the upper and lower respiratory system, the diaphragm, the pleura and the pericardium, as well as abdominal scars loci have been reported in the literature.

Granular cell breast tumour mimicking infiltrating carcinoma.

Granular cell tumour (GCT) is a rare, usually benign neoplasm that can mimic carcinoma on breast imaging. GCT can originate anywhere in the body but is most frequently found in the head and neck region, particularly in the tongue. Of the reported cases, 6% have occurred in the breast, most commonly in the upper inner quadrant.

Lung ossification: an orphan disease.

Diffuse pulmonary ossification (DPO) is a rare entity which is characterized by metaplastic bone formation in the lung parenchyma. It is an uncommon condition without significant symptoms, which is usually diagnosed on autopsy. Diffuse pulmonary ossification can be easily misdiagnosed as one of interstitial lung diseases due to diffuse pulmonary lesions.

Primary glomangiosarcoma of the lung: A case report.

Background: Glomus tumor is an uncommon neoplasm derived from cells of the neuromyoarterial glomus or glomus body. Most glomus tumours occur in the dermis and subcutaneous tissues. A case of a primary pulmonary glomus tumour originating in the right upper lobe is presented.
