Nodular fasciitis a correlative cytologic and histologic study of 13 cases. 1981

I Dahl, and M Akerman

Nodular fasciitis, the most common pseudosarcomatous proliferative lesion of the soft tissues, is well defined histologically but not cytomorphologically. A histologic and cytologic study of 13 cases of nodular fasciitis is presented. Nodular fasciitis is characterized histologically by proliferating fibroblastlike cells that vary from thin, elongated and spindle shaped with elongated nuclei to plump with one or more large, oval nuclei. The appearance of nodular fasciitis in fine needle aspirations is characterized by the presence of tumor cells varying widely from spindle shaped with long cytoplasmic processes to more plump and cytoplasmatic with one or more nuclei with nucleoli. An attempt to correlate the histologic and cytologic appearances is made. It is stressed that all the cells in nodular fasciitis lack histologic and cytologic signs of malignancy. The differential diagnosis is discussed. The cytomorphology of nodular fasciitis is fairly characteristic, making it possible to recognize these lesions in fine needle aspirates.

D002467	Cell Nucleus	Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)	Cell Nuclei,Nuclei, Cell,Nucleus, Cell

D003593	Cytoplasm	The part of a cell that contains the CYTOSOL and small structures excluding the CELL NUCLEUS; MITOCHONDRIA; and large VACUOLES. (Glick, Glossary of Biochemistry and Molecular Biology, 1990)	Protoplasm,Cytoplasms,Protoplasms
D005208	Fasciitis	Inflammation of the fascia. There are three major types: 1, Eosinophilic fasciitis, an inflammatory reaction with eosinophilia, producing hard thickened skin with an orange-peel configuration suggestive of scleroderma and considered by some a variant of scleroderma; 2, Necrotizing fasciitis (FASCIITIS, NECROTIZING), a serious fulminating infection (usually by a beta hemolytic streptococcus) causing extensive necrosis of superficial fascia; 3, Nodular/Pseudosarcomatous /Proliferative fasciitis, characterized by a rapid growth of fibroblasts with mononuclear inflammatory cells and proliferating capillaries in soft tissue, often the forearm; it is not malignant but is sometimes mistaken for fibrosarcoma.
