A neoformation has been surgically withdrawn from third finger extensor tendon of the right hand of a 52 year male subject. Light (LM) and electron microscope (EM) observations from a number of tissue fragments allowed the identification of tumor nature, which appeared a giant cell tendon sheath. Moreover, some structural patterns have been described and compared to the previously reported cases. In areas of major cell density, parenchyma does not show lobular or gland-like organization; on the other hand, wide zones characterized by an amorphous matrix, progressively replacing collagen and containing elongated cells, are present. Giant multinucleated cells, mostly localized close to collagen bundles, can also be revealed. Unexpectedly, no foam cells appear and no phagocytized cell debris can be identified in giant multinucleated cells. Engulfed crystals are, differently, evidentiated by electron microscopy, both in mono- and multinucleated cell cytoplasm. Their electron density and their localization within cytoplasmic vacuoles suggest the presence of calcium. A correlation between giant cells and osteoclasts is then proposed. Multiple variously oriented centrioles support the possible mitotic genesis of multinucleated giant cells, which never show, on the other hand, fusion features. Siderosomes and residual bodies are also present. An unusual, diffuse thickening of nuclear lamina, only interrupted at nuclear pore level, is described and discussed.
"Persian Gulf syndrome" refers to a group of clinical findings found in military personnel who served in the Persian Gulf War. The most commonly reported symptoms include chronic fatigue, headache, and neurologic disorders. Recently, new information has linked Whipple's disease and Ki-1 anaplastic large cell lymphoma to this syndrome. Presented here is an unusual case of multiple giant cell tumors of the hand in a patient with documented Persian Gulf syndrome. The epidemiologic significance between these two entities is unclear, because this is a single reported case. However, the practical message is clear. Physicians must meticulously evaluate patients who are veterans of the Persian Gulf conflict to further our understanding and confirm the existence of this syndrome.
