Emma Louise Call (1847 – 1937) was an American physician and obstetrician.
Call was one of the first female physicians in the United States, and was the first female member of the Massachusetts State Medical Society. She gave much of her time to teaching younger women clinical medicine and obstetrics.
Call is eponymously remembered for her description of Call-Exner bodies in 1875.

I entered the Medical Department of the University the first year that women were admitted. The first class of women…were naturally the objects of much attention critical or otherwise (especially critical) so that in many ways it was quite an ordeal. I believe that only one of the medical faculty was even moderately in favor of the admission of women, so that it speaks well for their conscientiousness when I say (with possibly one exception) we felt that we had [a] square deal from them all.Emma Louise Call, 1924
Call-Exner bodies (1875)
Call-Exner bodies are small follicle-like structures that punctuate the sheet-like arrangement of 30-60% of granulosa cell tumours (GCTs).
GCTs are rare sex cord stromal tumours of the ovary, made up of granulosa cells (sex cord) and stromal cells (thecal cells or fibroblasts) which often secrete oestrogen. They are made up of amorphous, eosinophilic, periodic acid-Schiff-positive hyaline material surrounded by granulosa cells, and appear as rosettes of granulosa cells surrounding an eosinophilic material.
In 1875, Emma L. Call and Siegmund Exner described tiny cells among the ovarian granulosa cells in the rabbit ovary which resembled ova. They suggested that these may arise from the epithelium of the Graafian follicle as well as from the germinal epithelium.

These vacuolar areas of cystic degeneration surrounded by granulosa cells are indicative of granulosa growth and their presence can be an aid to the diagnosis of granulosa cell tumours, which often have a variable microscopic pattern. In the classic variety, the granulosa cells are arranged in clusters around the cystic cavity – Call–Exner bodies or rosettes.
Call-Exner-like areas can also be observed in gonadoblastomas; sclerosing stromal tumours of the ovary; and in endometrioid carcinoma of the ovary.
