Hodgkin lymphoma mimicking a large soft tissue sarcoma of the shoulder: the essential role of immunohistochemistry in histopathological diagnosis.

The shoulder and axillary regions contain various complex anatomical structures in close proximity, many of which can give rise to neoplasms. Determining the origin and hence the exact diagnosis of advanced (diffuse) tumours in this region may become problematic. In view of the tumour morphology and the affected location in this case, we highlighted the importance of Hodgkin lymphoma immunohistochemistry interpretation in a tumour which was initially suspected to be a soft tissue sarcoma.

Carcinosarcoma of the thyroid: a case report.

Thyroid carcinosarcoma (TC) is a very rare, aggressive thyroid malignancy with a clinical course similar to anaplastic carcinoma. A thorough search of the literature reveals limited information regarding its behavior and treatment modalities. TC has a high mortality rate despite the multi-modal approach.

Splenic tuberculosis presenting as pyrexia of unknown origin.

We report a case of a previously healthy 38-year old lady who presented with prolonged fever and hepatosplenomegaly. Intensive investigations were performed for pyrexia of unknown origin which revealed negative. CT scan of the abdomen showed multiple hypodense lesions which did not respond to broad-spectrum antibiotics.

Sinonasal inverted papilloma with malignant transformation in the middle ear: a multicentric origin?

Inverted papilloma is a rare, benign tumour representing only 0.5 to 4 per cent of all sinonasal neoplasms; its involvement of the middle ear is extremely rare. We present a case of multicentric inverted papilloma in the sinonasal region and middle ear in a 54-year-old man.
