Solid pseudopapillary neoplasm presenting as a primary ovarian mass in an eighteen-year-old female: report of a case and review of the literature

Primary solid pseudopapillary neoplasm of the ovary: Report of a case and review of the literature

“…Desphande et al first reported 3 cases located in the ovary in 2010 [2]. All cases of ovarian SPN have been reported to occur in the absence of ectopic pancreatic tissue [2][3][4][5][6][7][8][9][10][11][12]. In the present case also, despite the whole sampling of the specimen, we did not find any ectopic pancreatic tissue within or adjacent to the tumor.…”

“…The age of the patients ranged from 17 to 57, with a mean age of 35.5 years, and the median age of 25 in primary ovarian SPNs. Ovarian SPNs are located in the right ovary in 63.6% of the cases [2][3][4][5][6][7][8][9][10][11][12]. The diameter of tumors ranged from 3 to 25.5 cm, in our case it was 4.5 cm.…”

“…SPNs are often asymptomatic or are associated with uncharacteristic abdominal symptoms. Three patients presented with an abdominal mass [2,7,11,12] and dysmenorrhea [12]. Totaly nine cases, including ours, had abdominal pain or discomfort [2,3,5,6,8,10,12].…”

“…Extrapancreatic SPN has been documented in other areas such as retroperitoneum, omentum, mesocolon, gastroduodenal area, colon and liver, which occur in ectopic pancreatic tissue [1]. The most common extrapancreatic site is the ovary (totaly 14 cases, including the present case) [2][3][4][5][6][7][8][9][10][11][12]. Desphande et al first reported 3 cases located in the ovary in 2010 [2].…”

“…In these cases, the tumor mostly arises from ectopic pancreatic tissue [1]. There are only 13 previous cases of primary ovarian SPN in the English literature [2][3][4][5][6][7][8][9][10][11][12]. We report here, an additional case of ovarian SPN, which is morphologically and immunophenotypically similar to that of the pancreas, in the right ovary of a 30-year-old woman, with a review of the literature on extrapancreatic SPN.…”
