Acute polyarthritis associated with birefringent lipid microspherules occurring in a patient with longstanding rheumatoid arthritis.

We describe a 52-year-old patient with longstanding rheumatoid arthritis (RA) who developed an acute polyarthritis of her hands and wrists. Synovial fluid analysis revealed the presence of intra and extracellular lipid microspherules with the typical appearance of Maltese crosses under polarized light microscopy. No other specific cause could be identified. This is the first description of an acute polyarthritis associated with lipid microspherules in RA.

Ultrastructural, immunohistochemical, and cytogenetic study of a malignant peripheral neuroectodermal tumor in a patient seropositive for human immunodeficiency virus.

A case of malignant peripheral neuroectodermal tumor occurring during the course of a human immunodeficiency virus (HIV) infection is reported. The patient was a male homosexual who presented with a rapidly enlarging tumor of the posterior lower thoracic wall. By light microscopic examination the tumor was a small cell tumor showing occasional structures suggestive of Homer-Wright rosettes. The strong positivity for neuron-specific enolase and the neurosecretory granules indicated the neural differentiation of the tumor. Its precise nature was shown cytogenetically by the presence of the t(11;22) translocation, which distinguished it from the classical neuroblastoma.

This report deals with such a case who presented with a mediastinal thymic tumor and superior vena cava syndrome. The authors emphasize the localization and the histological techniques that are utilized to ascertain the diagnosis.
