A 12-year-old child with a left small inhibitors scrotal mass was referred to our institution. On physical examination, the mass was located in the cefaled end of epididymis. Ultrasound examination revealed

normal testes on both sides and ipoechogenic mass 1 × 1 cm attached to left epididymis (Fig. 1). At operation, an encapsulated dark purple red mass was found attached to the head of the left epididymis. Frozen section showed normal splenic tissue. Accessory splenic tissue was not found in spermatic cord (Fig. 2). Postoperatively, ultrasound examination revealed that the orthotopic spleen was normal. We also performed abdominal and scrotal echographic examinations in parents and siblings. In a brother 14-year-old, an accessory little spleen (1.1 cm diameter) was found near to the splenic hilum (Fig. 3). SGF, first described in 1883 by Boestrem, represents 10% of scrotal masses. Different Decitabine concentration incidence in both sexes may be subsequent to a missed diagnosis because of ovary location and lack of symptoms. In the 4 cases reported in female patients, splenic tissue was adjacent to the ovary or mesovarium. Diagnosis may occur at any age (1-81 years): most reported patients (82%)

are younger than 30 years, but 50% of SGF have been described in children.1 In 1889, Pommer described a case associated with limb defects, micrognathia, anal atresia, and other congenital abnormalities. Antenatal ultrasound diagnosis GSK1349572 cost is reported in 2 cases.2 Unusual cases of right SGF were also described.3 A teratogenic insult occurring between 5 and 8 weeks of fetal life, when the spleen, gonads, limb buds, and mandible are developing has been postulated. Adhesion or lack of apoptosis at the interface between the splenic primordium and contiguous genital ridge may occur. Precursor structures of shoulder bones are very close: this is probably related to limbs malformations. The right-sided cases may be because of situs inversus. Colonization by splenic cells of an abnormal suspensory ligament of testis has been also suggested. The few cases of intragonadal spleen may be a consequence of induction of

hemopoietic potencies in gonadal mesenchyma. De Ravel 97 reported tetra-amelia and SGF in Roberts Histone demethylase syndrome and Alessandri in 2010 described a genetic mutation (RAB 23) in a family with Carpenter syndrome and SGF.4 Accessory spleen in a sibling, not previously reported to our knowledge, suggests familial predisposition of this disorder. Up to now, approximately 160 cases have been reported, mainly in the form of single case the majority was based on autopsy findings.1 Continuous type is associated with major congenital abnormalities (oro—facial and limb developmental abnormalities: SGFLD syndrome), cryptorchidism, spina bifida, cardiac defects, diaphragmatic hernia, hypoplastic lung, and anorectal abnormalities. Association with cryptorchidism is the most common (31%) particularly on the left side (65%).
