Fibrous dysplasia is a rare disorder of bone that is uncommon in the head and neck region. Herein, we present a rare case of polyostotic fibrous dysplasia involving the right temporal bone and thyroid cartilage in a 19-year-old male. This unique location necessitates close surveillance due to the proximity to the airway and the potential for malignant degeneration. DOI : 10.14302/issn.2379-8572...

Anatomical variants of the extrahepatic bile duct system occur in approximately 42% of the population. On the other hand, duplication of the common bile duct is a very rare congenital abnormality, which is often associated with recurrent cholangitis or pancreatitis, as well as an increased risk of malignant degeneration. Therefore diagnostics using MRI and ERCP as well as the therapeutic strate...

The congenital thymic cysts are rare. They have a congenital origin and they are benign. The differential diagnosis of acquired cysts, cystic thymoma and thymic malignancies in cystic degeneration can be particularly difficult. Rarely, they assume clinical relevance for the appearance of symptoms of compression, more typical of malignant lesions, and the association with thymoma was reported in...

Forty-five necropsied cases with primary degeneration of lower motor neurones are described and discussed. Of these, 36 are considered to be `typical' cases of motor neurone disease, eight of which showed no upper motor neurone lesions. The relation of the nine `atypical' cases to the remainder is discussed. It is concluded that motor neurone disease constitutes an ill-defined band in a broad s...

Swellings of the major salivary gland commonly lead to the differential diagnosis which includes benign and malignant tumors that are frequently associated with cystic degeneration or entirely cystic de novo. Only 6-9% of major salivary gland swellings are cystic lesions and 2-5 % are non-neoplastic in nature. This is a case report of such an asymptomatic unilateral parotid gland lesion in a 30...

Results: Benign disease was positive for p16 in 64%, EGFR in 50%, p53 in 30%, and cyclin D1 in 76%. IP with carcinomatous degeneration was positive for p16 in 14%, EGFR in 71%, p53 in 62%, and cyclin D1 in 76%. The differences in staining positivity between benign and malignant disease reached significance for p16 and p53 only. Mean percentage staining by tumor surface area for IP and IP with c...

A 60 year old woman with idiopathic Parkinson's disease had been prescribed thioridazine for schizophrenia. Five months after this was stopped, Sinemet also considered of dubious therapeutic value, was withdrawn. One week later she developed features of the neuroleptic malignant syndrome (NMS) accompanied by myoglobinuric renal failure. Post-mortem examination confirmed Lewy body degeneration i...

Adenomyoepithelial adenosis of the breast is extremely rare. We treated a 35-year-old woman with two small painless hard lumps in her breasts. On ultrasonography, the lesion in the right breast (upper inner quadrant) showed heterogeneous echogenicity and irregular, well-defined, uniformly hypoechoic nodules separated by funiform hyperechoic areas. The entire lesion had unclear boundaries. Excis...

Persistent Müllerian duct syndrome is a rare genetic disorder characterized by a male with retained Müllerian structures. Remnant excision must be considered due to the possibility of malignant degeneration. We review a case of delayed diagnosis in a 25-year-old man presenting with hematuria. Preoperative counseling must emphasize the risk of malignancy versus the risks to fertility. The da Vin...

Solid pseudopapillary neoplasm (SPN) of the pancreas is considered a low-malignant neoplasm with a good prognosis. However, 5% to 15% of patients with SPNs develop metastatic disease, most commonly in the liver. Metastatic hepatic malignancies that show pseudocystic features are rare. Here we describe the case of a middle-aged female with a cystic liver metastasis from SPN. To the best of our k...
