Primary low grade adenocarcinoma occurring in the inguinal region

Abstract

An unusual case of primary adenocarcinoma occurring in the inguinal region of an elderly woman is reported. It appeared to have arisen from the mesothelium of the canal of Nuck. It recurred and involved one inguinal lymph node three years after the diagnosis and seven years after the initial appearance of the mass. The absence of associated peritoneal tumor distinguishes this case from other reported primary malignant neoplasms of the hernial sac.

A case report of advanced ovarian cancer detected due to an inguinal metastasis in the canal of Nuck

“…We searched PubMed and Japanese medical abstract databases for cancer cases with a hydrocoele in the canal of Nuck and found four reported cases (Table 1) [[12], [13], [14], [15]]. All reported cases occurred on the right side.…”

Radical resection of an endometrioid carcinoma arising from endometriosis in the round ligament within the right canal of Nuck: a case report and literature review

“…Although they showed no invasion to tissues around the canal of Nuck, 2 of the 4 cases ( Table 1 , case 1, 2) showed recurrence in the inguinal region at 3 months and 3 years after the first surgery, respectively. Additionally, 2 of the 4 cases ( Table 1 , case 2, 3) showed lung metastasis at 21 months and 2 years after the first surgery, respectively ( Irvin et al, 1998 ; Ito et al, 2010 ; Mesko et al, 1988 ; Sun et al, 1979 ). D.…”

“…The entire fold is normally obliterated within the first year of life in female infants. Occasionally, the canal of Nuck remains patent and permits the seeding of endometriotic tissue in inguinal soft tissues ( Irvin et al, 1998 ; Ito et al, 2010 ; Mesko et al, 1988 ; Sun et al, 1979 ).…”

Endometriosis of the Canal of Nuck: A Systematic Review of the Literature

“…A total of 20 studies (18 case reports and 2 case series), which comprised 36 patients who were diagnosed with an endometriotic lesion arose in the NC, were finally considered eligible for inclusion in the qualitative analysis of the present systematic review [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41].…”
